RX 1, TX 1 The RX and TX SMA ports for the Chain 1 Low-Band Duplexer or High-Band Duplexer (MIMO mode only). In SISO mode, these unused ports are protected by the Duplexer Cap.

Duplexer

N Connector Female N-type connector into which the antenna cable is plugged.
SMA Ports High-band and low-band channel SMA ports.

LEDs

Signal LEDs

Signal 4 LED will light blue when on.
Signal 3 LED will light green when on.
Signal 2 LED will light yellow when on.
Signal 1 LED will light red when on.
Bootup to airOS When powering on, the Power, MIMO, LINK, and Signal 1-4 LEDs light on. Once the CPU code takes over, the MIMO, LINK, and Signal 1-3 LEDs turn off. The Signal 4 LED remains lit to indicate the boot sequence is underway.
Initializing airFiber Software When the airFiber application begins to boot under airOS, the Signal 4 LED goes from solidly on to a 2.5 Hz flash. This continues until the AF-11FX radio is fully booted.
Signal Level Once fully booted, the Signal 1-4 LEDs act as a bar graph showing how close the AF-11FX is to ideal aiming. This is auto-scaled based on the link range, the antenna gains, and the configured TX power of the remote AF-11FX. Each Signal LED has three possible states: On, Flashing, and Off. All Signal LEDs would be solidly on in an ideal link. For example, if the link has a 1 dB loss, the Signal 4 LED will flash; a 2 dB loss and the Signal 4 LED will turn off. The full bar graph LED states are shown below.

dB loss	0	-1	-2	-3	-4	-5	-6	-7	-8	-9	-10	-11	-12	-13
	1	F	0	0	0	0	0	0	0	0	0	0	0	0

Alignment

Tips

• To accurately align the airFiber X radios for best performance, you MUST align only one end of the link at a time.
- You may need to use additional hardware to compensate for issues such as the improper orientation of a mounting pole or significant elevation differences between airFiber X radios.

Establishing a Link

Adjust the positions of the Master and the Slave to establish a link. The following section features the airFiber X antenna, AF-11G35.

Note: The Master must be aimed first at the Slave because the Slave does not transmit any RF signal until it detects transmissions from the Master.

Note: For complete details on the antenna, refer to the Quick Start Guide for your specific model.

1. Master Visually aim the Master at the Slave. To adjust the Master's position, adjust the azimuth and elevation:

Adjust the azimuth:

a. Loosen the four flange nuts on the two pole clamps.
b. Rotate the antenna to point towards the other end of the link.
c. Tighten the four flange nuts on the two pole clamps.

Adjust the elevation angle:

a. Loosen the eight hex head bolts to so that the washers can spin freely by hand.
b. Tighten or loosen the Elevation Adjustment Bolt to set the desired tilt.
c. Tighten the eight hex head bolts.

Note: Do NOT make simultaneous adjustments on the Master and Slave.

1. Slave Visually aim the Slave at the Master. To adjust the Slave's position, adjust the azimuth and elevation as described in step 1.
2. Check to see if a link is established. Ensure that the LINK LED is solidly lit green and the Signal LEDs of the Slave are displaying signal levels.

1. Slave Aim the Slave at the Master to achieve the strongest signal level on the Master.

Note: Refer to "Signal LEDs" on page 2 for details on the signal values.

Note: Maximum signal strength can best be achieved by iteratively sweeping through both azimuth and elevation.

1. Master Aim the Master at the Slave to achieve the strongest signal level on the Slave.
2. Repeat steps 4 and 5 until you achieve an optimal link, with all four Signal LEDs solidly lit. This ensures the best possible data rate between the airFiber X radios.
3. Lock the alignment on both airFiber X antennas by tightening all the nuts and bolts.
4. Observe the Signal LEDs of each airFiber X radio to ensure that the values remain constant while tightening the nuts and bolts. If any LED value changes during the locking process, loosen the nuts and bolts, finalize the alignment of each airFiber X antenna again, and retighten the nuts and bolts.

Chapter 5: Wireless Tab

The Wireless tab contains options to set up the wireless part of the link. This includes wireless mode, link name, frequencies, output power, speed, wireless security, and advanced wireless settings.

Test Changes To try the changes without saving them, click Test Changes. A new message appears. You have two options:

• Apply To immediately save your changes, click Apply.
• Discard To cancel your changes, click Discard. If you do not click Apply within 180 seconds (the countdown is displayed), the AF-11FX radio resumes its earlier configuration.

Revert Changes To cancel your changes, click Revert Changes.

Save Changes To save your changes, click Save Changes.

Write down the settings you configure on the Wireless tab. You will need to enter the same settings on the AF-11FX radio at the other end of your PtP link. The exceptions are as follows:

• Wireless Mode Configure one AF-11FX radio as the Master and the other as the Slave.
• TX Frequency, RX Frequency The TX Frequency and RX Frequency on one AF-11FX radio are configured as the RX Frequency and TX Frequency, respectively, on the other radio.

Basic Wireless Settings

In this section, configure the basic wireless settings, such as wireless mode, link name, country code, frequencies, output power, speed, and gain.

Wireless Mode By default, the Wireless Mode is Slave. You must configure one airFiber X radio as Master because each PtP link must have one Master.

Link Name Enter a name for your PtP link. This name must be the same on both Master and Slave radios in order for them to connect.

Country Code This is preset to Licensed and cannot be changed.

Channel Bandwidth Select the appropriate channel size: 3.5, 5, 7, 10, 14, 20, 28, 30, 40, 50, or 56 MHz.

Note:. The available channel bandwidths depend on the regulatory requirements of the currently selected country or region.

Radio Mode Use this setting to configure the mode of the radio to MIMO or SISO.

Output Power (EIRP) Defines the maximum average transmit output power (in dBm) of the airFiber X radio. To specify the output power, use the slider or manually enter the output power value. The transmit power level maximum is limited according to country regulations.

Note: The Antenna Gain and Cable Loss should be configured before the Output Power. This is because the range of the Output Power field is affected by the Antenna Gain and Cable Loss values – changing the antenna gain or cable loss adjusts the maximum and minimum values you can select using the Output Power slider. Since the Output Power already includes the antenna gain and cable loss, it represents EIRP; therefore, the value of Output Power is actually the total power the radio is transmitting over the air. The current transmit power is displayed by the TX Power (EIRP) field on the Dashboard.

Note: The airFiber X radio may limit the output power to a value less than the value specified by this field, to comply with regulatory region requirements. For a list of maximum output power values by country and region, refer to "Frequency Ranges and Power Levels per Country/Region" on page 47.

Antenna Gain Enter the gain in dBi of the antenna that is used in your installation. An improper value could cause DFS false detections when operating on DFS frequencies.

Cable Loss Enter the cable loss in dB of the cable that is used in your installation. An improper value could cause DFS false detections when operating on DFS frequencies.

Receive Target Power To use the Automatic Transmit Power Control (ATPC) feature, enable this option and enter the desired power level that the receiver (on the far end of the link) should see from this radio.

In ATPC, each airFiber X radio monitors the amount of power received by the radio at the other end of the link. If the reported value differs from the Receive Target Power value, the radio automatically adjusts its transmit output power to match the Receive Target Power value. The radio will use its Output Power (EIRP) setting as the maximum level at which it will transmit to maintain the Receive Target Power.

Maximum Modulation Rate or Modulation Rate Higher modulations support greater throughput but generally require stronger RF signals and a higher Signal-to-Noise Ratio (SNR). By default, Automatic Rate Adaptation is enabled, and Maximum Modulation Rate is displayed. This allows the airFiber X radio to automatically adjust the modulation rate to changing RF signal conditions. Under certain conditions, you may prefer to lock the Maximum Modulation Rate to a lower setting to improve link performance.

When Automatic Rate Adaptation is disabled, Modulation Rate is displayed. Lock the Modulation Rate to the setting of your choice.

Select one of the available modulation rates. The available values depend on the Radio Mode setting:

• If Radio Mode is set to MIMO:

• 10x (1024QAM MIMO)
• 8x (256QAM MIMO)
- 6x (64QAM MIMO)
• 4x (16QAM MIMO)
• 2x (QPSK MIMO)
• 1x (QPSK SISO)
• 1/4x (QPSK SISO)

• If Radio Mode is set to SISO:

• 5x (1024QAM SISO)
• 4x (256QAM SISO)
• 3x (64QAM SISO)
• 2x (16QAM SISO)
• 1x (QPSK SISO)
- 1/4x (QPSK SISO)

Automatic Rate Adaptation Enabled by default, this option allows the airFiber X radio to automatically adjust the modulation rate to changing RF signal conditions.

Frequency Settings

The Valid Frequencies for your Country Code selection are displayed. Ensure that you use frequencies that comply with the local country regulations.

TX Frequency Enter a valid TX frequency. The current state is displayed.

RX Frequency Enter a valid RX frequency. The current state is displayed.

Wireless Security

airFiber uses 128-bit, AES (Advanced Encryption Standard) encryption at all times.

Key Type Specifies the character format.

• HEX By default, this option uses hexadecimal characters. 0-9, A-F, or a-f are valid characters.
• ASCII ASCII uses the standard English alphabet and numeric characters (0-9, A-Z, or a-z).

Key Select the format of the MAC address.

- HEX Enter 16 bytes (eight, 16-bit hexadecimal values). You can omit zeroes and use colons, similar to the IPv6 format. The default is:

0000:0000:0000:0000:0000:0000:0000:0000

Note: The airFiber Configuration Interface supports IPv6 formats excluding dotted quad and “::” (double-colon) notation.

- ASCII Enter a combination of alphanumeric characters. Using 128-bit SHA1 (Secure Hash Algorithm 1), the airFiber X radio hashes the ASCII key to create a 128-bit key for AES.

Advanced Wireless Settings

Enhanced MIMO Select this option to enable the Enhanced MIMO feature. Enhanced MIMO increases sensitivity which may result in greater TX throughput in low-noise environments. If enabling this feature does not result in improved throughput, the noise level is too high and you should disable this feature. This feature is disabled by default.

Automatic Power Backoff This feature allows the radio to automatically adjust the maximum TX power per modulation so that the radio never transmits at a higher power than each modulation rate can decode. The default values in the Max 10x/8x/6x/4x Conducted Power fields are values determined to work at all temperatures and all frequencies supported by the radio.

It may, however, be possible to increase the maximum TX power for one or more modulations based on your radio's operating environment. For example, if a radio is running at 6x and trying to switch into 8x operation, you can increase the Max 8x Conducted Power value 1 dB at a time to see if the radio can maintain 8x operation (Automatic Power Backoff must be enabled to allow the Max Conducted Power fields to be edited). The same can be done with 6x and 4x up to the maximum conducted power of the radio.

Max 10x/8x/6x/4x Conducted Power The maximum conducted power for the 10x/8x/6x/4x modulation rates. Each field is editable only if Automatic Power Backoff is enabled.

Restore Default Backoffs Click Restore to restore the default Max Conducted Power values.

Chapter 6: Network Tab

The Network tab allows you to configure settings for the management network. There are two ways to access the airFiber Configuration Interface:

• Management Port Enabled by default. Use a direct connection to the Management port for out-of-band management.
• In-Band Management Enabled by default. In-band management is available through the local Data port or the Data port at the other end of the link.

The Management port and in-band management share the default IP address of 192.168.1.20.

Test Changes To try the changes without saving them, click Test Changes. A new message appears. You have two options:

• Apply To immediately save your changes, click Apply.
• Discard To cancel your changes, click Discard. If you do not click Apply within 180 seconds (the countdown is displayed), the AF-11FX radio resumes its earlier configuration.

Revert Changes To cancel your changes, click

Revert Changes.

Save Changes To save your changes, click Save Changes.

Management Network Settings

In-Band Management Enabled by default. In-band management is available through the local Data port or the Data port at the other end of the link.

Note: If In-Band Management is enabled, ensure that each airFiber X radio in a link has a unique IP Address. If the airFiber X radios use the same IP Address, you may lose access via the Data ports.

Management IP Address The airFiber X radio can use a static IP address or obtain an IP address from its DHCP server.

- DHCP Keep the default, DHCP, to use DHCP reservation on your router to assign a unique IP Address. The local DHCP server assigns a reserved IP address, gateway IP address, and DNS address to the airFiber X radio.

Note: If you select the DHCP option, ensure that you use DHCP reservation because if you do not know the IP address, then the only way to manage the airFiber X radio is to reset the airFiber X radio to its factory default settings. (Press and hold the Reset button for more than five seconds.) Its default Management IP Address is reset to 192.168.1.20.

• DHCP Fallback IP Specify the IP address the airFiber X radio should use if a DHCP server is not found.
• DHCP Fallback Netmask Specify the netmask the airFiber X radio should use if a DHCP server is not found.

• Static Assign static IP settings to the airFiber X radio.

Note: IP settings should be consistent with the address space of the airFiber X radio's network segment.

• IP Address Specify the IP address of the airFiber X radio. This IP will be used for device management purposes.
• Netmask When the netmask is expanded into its binary form, it provides a mapping to define which portions of the IP address range are used for the network devices and which portions are used for host devices. The netmask defines the address space of the airFiber X radio's network segment. The 255.255.255.0 (or "/24") netmask is commonly used on many Class C IP networks.
• Gateway IP Typically, this is the IP address of the host router, which provides the point of connection to the Internet. This can be a DSL modem, cable modem, or WISP gateway router. The airFiber X radio directs data packets to the gateway if the destination host is not within the local network.
• Primary DNS IP Specify the IP address of the primary DNS (Domain Name System) server.
• Secondary DNS IP Specify the IP address of the secondary DNS server. This entry is optional and used only if the primary DNS server is not responding.

Management VLAN If enabled, automatically creates a management Virtual Local Area Network (VLAN).

- VLAN ID Enter a unique VLAN ID from 2 to 4094.

Auto IP Aliasing If enabled, automatically generates an IP address for the corresponding WLAN/LAN interface. The generated IP address is a unique Class B IP address from the 169.254.X.Y range (netmask 255.255.0.0), which is intended for use within the same network segment only. The Auto IP always starts with 169.254.X.Y, with X and Y as the last two octets from the MAC address of the airFiber X radio. For example, if the MAC address is 00:15:6D:A3:04:FB, then the generated unique Auto IP will be 169.254.4.251. (The hexadecimal value, FB, converts to the decimal value, 251.)

The Auto IP Aliasing setting can be useful because you can still access and manage devices even if you lose, misconfigure, or forget their IP addresses. Because an Auto IP address is based on the last two octets of the MAC address, you can determine the IP address of a device if you know its MAC address.

airView Port The port number associated with the airView spectrum analyzer tool. The default value is 18888.

For detailed information on the airView tool, refer to "airView" on page 38.

Mgmt Speed This is the speed of the Management port. By default, the option is Auto. The airFiber X radio automatically negotiates transmission parameters, such as speed and duplex, with its counterpart. In this process, the networked devices first share their capabilities and then choose the fastest transmission mode they both support.

To manually specify the maximum transmission link speed and duplex mode, select one of the following options: 100 Mbps-Full, 100 Mbps-Half, 10 Mbps-Full, or 10 Mbps-Half. If you are running extra long Ethernet cables, a link speed of 10 Mbps could help to achieve better stability.

Full-duplex mode allows communication in both directions simultaneously. Half-duplex mode allows communication in one direction at a time, alternating between transmission and reception.

Data Port Ethernet Settings

DATA Speed This is the speed of the Data port.

The default is Auto, which allows the radio to operate at a speed of 1 Gbps. The airFiber X radio automatically negotiates transmission parameters, such as speed and duplex, with its counterpart. In this process, the networked devices first share their capabilities and then choose the fastest transmission mode they both support.

To manually specify the maximum transmission link speed and duplex mode, select one of the following options: 100 Mbps-Full, 100 Mbps-Half, 10 Mbps-Full, or 10 Mbps-Half.

Full-duplex mode allows communication in both directions simultaneously. Half-duplex mode allows communication in one direction at a time, alternating between transmission and reception.

Flow Control If enabled, the airFiber X radio generates and responds to Ethernet layer PAUSE frames. The airFiber X radio regulates inbound traffic from the customer's network to avoid buffer overflows within the airFiber X radio. Flow control has the effect of controlling the inter-packet spacing of packets headed into the airFiber Data interface.

Multicast Filter If enabled, the filter blocks multicast traffic from overloading the CPU when in-band management is enabled. This allows the airFiber X radio to be managed in-band when the customer's network is carrying large volumes of multicast traffic, such as IPTV. The filter does not block multicast traffic going over the radio; it simply blocks it from reaching the airFiber X radio's management interface CPU.

Ethernet Carrier Drop Settings

The Ethernet Carrier Drop settings are used to control failover switching between the primary and backup link in response to capacity loss due to rain.

Carrier Drop Operation This setting is used to control the Ethernet Carrier Drop feature. Settings are: Disabled, Enabled, and Use Pulse. The default is Disabled.

Use Pulse and Enabled are the two different methods used to signal to the failover mechanism that it should switch to the backup link:

• Use Pulse The LAN link is toggled off.
• Enabled The LAN link will be turned off and left off.

Pulse Duration (Available if Carrier Drop Operation is set to Use Pulse.) This is the length of time that the LAN link remains down to trigger failover. The default is 5 seconds.

Block Data After Pulse (Available if Carrier Drop Operation is set to Use Pulse.) Enable this option to stop data from passing through the link when it is experiencing loss of capacity. The default is Off.

Enable Ethernet If No Session Enable this option to allow management data (such as GUI, SNMP, and ping packets) to pass, even if the Block Data After Pulse option is enabled. The default is Off.

Wait for First Session Enable this option to cause the system to wait until the Ethernet link has been successfully established following a power cycle, to keep the link from being dropped due to the throughput being below threshold. The default is Off.

First Session Validation Timer Use this setting to specify how long to wait before triggering a link failure due to insufficient threshold capacity following a power cycle. The default is 0 seconds.

TX Capacity Low Threshold This is the minimum allowable TX capacity; if the TX capacity goes below this threshold, the Ethernet link will be dropped. The default is 0 Mbps.

TX Capacity High Threshold This is the TX capacity required before a dropped link can be declared to be operational again. The Ethernet link will remain down until the TX capacity reaches this threshold. The default is 0 Mbps. This setting should be greater than the TX Capacity Low Threshold to avoid flutter and multiple OSPF convergences.

RX Capacity Low Threshold This is the minimum allowable RX capacity; if the RX capacity goes below this threshold, the Ethernet link will be dropped. The default is 0 Mbps.

RX Capacity High Threshold This is the RX capacity required before a dropped link can be declared to be operational again. The Ethernet link will remain down until the RX capacity reaches this threshold. The default is 0 Mbps. This setting should be greater than the RX Capacity Low Threshold to avoid flutter and multiple OSPF convergences.

Low Threshold Timer This is the number of continuous seconds that the radio must remain under the minimum TX or RX capacity threshold before the link is dropped. If set to 0, then as soon as capacity drops below a set limit, the Ethernet link will be dropped. Default is 0 seconds.

High Threshold Timer This is the number of continuous seconds that the radio must remain above the maximum TX or RX capacity threshold before the link is declared operational again. The default is 0 seconds.

Ping Watchdog

Ping Watchdog sets the airFiber X radio to continuously ping a user-defined IP address (the Internet gateway, for example). If it is unable to ping under the user-defined constraints, the airFiber X radio will automatically reboot. This option creates a kind of "fail-proof" mechanism.

Ping Watchdog is dedicated to continuous monitoring of the specific connection to the remote host using the Ping tool. The Ping tool works by sending ICMP echo request

packets to the target host and listening for ICMP echo response replies. If the defined number of replies is not received, the tool reboots the airFiber X radio.

Ping Watchdog Enables use of Ping Watchdog.

• IP Address To Ping Specify the IP address of the target host to be monitored by Ping Watchdog.
• Ping Interval Specify the time interval (in seconds) between the ICMP echo requests that are sent by Ping Watchdog. The default value is 300 seconds.
• Startup Delay Specify the initial time delay (in seconds) until the first ICMP echo requests are sent by Ping Watchdog. The default value is 300 seconds.

The Startup Delay value should be at least 60 seconds as the network interface and wireless connection initialization takes a considerable amount of time if the airFiber X radio is rebooted.

• Failure Count to Reboot Specify the number of ICMP echo response replies. If the specified number of ICMP echo response packets is not received continuously, Ping Watchdog will reboot the airFiber X radio. The default value is 3.
• Save Support Info Enabling this option generates a support information file.

SNMP Agent

Simple Network Monitor Protocol (SNMP) is an application layer protocol that facilitates the exchange of management information between network devices. Network administrators use SNMP to monitor network-attached devices for issues that warrant attention.

The airFiber X radio contains an SNMP Agent, which does the following:

• Provides an interface for device monitoring using SNMP
• Communicates with SNMP management applications for network provisioning
• Allows network administrators to monitor network performance and troubleshoot network problems

For the purpose of equipment identification, configure the SNMP Agent with contact and location information:

SNMP Agent Enables the SNMP Agent.

• SNMP Community Specify the SNMP community string. It is required to authenticate access to Management Information Base (MIB) objects and functions as an embedded password. The airFiber X radio also supports a read-only community string; authorized management stations have read access to all the objects in the MIB except the community strings, but do not have write access. The airFiber X radio supports SNMP v1. The default SNMP Community is public.
• Contact Specify the contact who should be notified in case of emergency.
• Location Specify the airFiber X radio's physical location.

Web Server

The following Web Server parameters can be set:

Secure Connection (HTTPS) If enabled, the Web Server uses secure HTTPS mode.

- Secure Server Port If secure HTTPS mode is used, specify the TCP/IP port of the Web Server.

Telnet Server

The following Telnet Server parameters can be set:

Telnet Server This option activates Telnet access to the airFiber X radio.

- Server Port Specify the TCP/IP port of the Telnet Server.

NTP Client

Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. You can use it to set the system time on the airFiber X radio. If the Log option is enabled, then the system time is reported next to every log entry that registers a system event.

NTP Client Enables the airFiber X radio to obtain the system time from a time server on the Internet.

- NTP Server Specify the IP address or domain name of the NTP server.

Dynamic DNS

Domain Name System (DNS) translates domain names to IP addresses; Each DNS server on the Internet holds these mappings in its respective DNS database. Dynamic Domain Name System (DDNS) is a network service that notifies the DNS server in real time of any changes in the airFiber X radio's IP settings. Even if the airFiber X radio's IP address changes, you can still access the airFiber X radio through its domain name.

Dynamic DNS If enabled, the airFiber X radio allows communications with the DDNS server.

• Host Name Enter the host name of the DDNS server.
• Username Enter the user name of the DDNS account.
• Password Enter the password of the DDNS account.
• Show Password Check the box to display the password characters.

System Log

System Log This option enables the registration routine of system log (syslog) messages. By default it is disabled.

- Remote Log Enables the syslog remote sending function. System log messages are sent to a remote server, which is specified in the Remote Log IP Address and Remote Log Port fields.

• Remote Log IP Address The host IP address that receives syslog messages. Properly configure the remote host to receive syslog protocol messages.
• Remote Log Port The TCP/IP port that receives syslog messages. 514 is the default port for the commonly used system message logging utilities.

Every logged message contains at least a system time and host name. Usually a specific service name that generates the system event is also specified within the message. Messages from different services have different contexts and different levels of detail. Usually error, warning, or informational system service messages are reported; however, more detailed debug level messages can also be reported. The more detailed the system messages reported, the greater the volume of log messages generated.

For more information on the system log, refer to "Log" on page 40.

Device Discovery

Discovery Enables device discovery, so the airFiber X radio can be discovered by other Ubiquiti devices through the Discovery tool.

CDP Enables Cisco Discovery Protocol (CDP) communications, so the airFiber X radio can send out CDP packets to share its information.

Charts

Enable top chart Check the box to enable the top chart. Select the desired chart to display in the top chart panel on the main view. There are two options:

- Waterfall This time-based graph shows the aggregate energy collected for each frequency since the start of the airView session. The energy color designates its amplitude. Cooler colors represent lower energy levels (with blue representing the lowest levels) in that frequency bin, and warmer colors (yellow, orange, or red) represent higher energy levels in that frequency bin.

The Waterfall View's legend (top-right corner) provides a numerical guide associating the various colors to power levels (in dBm). The low end of that legend (left) is always adjusted to the calculated noise floor, and the high end (right) is set to the highest detected power level since the start of the airView session.

- Channel Usage For each channel, a bar displays a percentage showing the relative "crowdedness" of that specific channel. To calculate this percentage, the airView Spectrum Analyzer analyzes both the popularity and strength of RF energy in that channel since the start of an airView session.

Note: airFiber X radio channels are not related to Wi-Fi channels which are determined by IEEE standards. airFiber X radio channels are numbered consecutively starting with 0 and are 28 MHz in width.

Enable Waveform chart (middle) Check the box to enable the middle chart. This time-based graph shows the RF signature of the noise environment since the start of the airView session. The energy color designates its amplitude. Cooler colors represent lower energy levels (with blue representing the lowest levels) in that frequency bin, and warmer colors (yellow, orange, or red) represent higher energy levels in that frequency bin.

The spectral view over time will display the steady-state RF energy signature of a given environment.

Enable Real-time chart (bottom) Check the box to enable the bottom chart. This graph displays a traditional spectrum analyzer in which energy (in dBm) is shown in real time as a function of frequency. There are three traces in this view:

• Current (Yellow) Shows the real-time energy seen by the device as a function of frequency.
  • Average (Green) Shows the running average energy across frequency.
  • Maximum (Blue) Shows updates and maximum power levels across frequency.

Real-Time Traces

The following settings apply only to the Real-time chart:

Current Real-time Trace Check the Enable box to enable the real-time trace. When enabled, the yellow outline on the Real-time chart represents the real-time power level of each frequency. The refresh speed depends on the FPS.

Averages Trace Check the Enable box to enable the averages trace. When enabled, the averages trace is represented by the green area on the Real-time chart, which displays the average received power level data since the start of the airView session. To enable a shaded green area, check the Shaded Area box. To display only a green outline without the shaded area, uncheck the Shaded Area box.

Maximum Power Levels Trace Check the Enable box to enable the maximum power trace. When enabled, the maximum power trace is represented by the blue area on the Real-time chart, which displays the maximum received power level data since the start of the airView session. To enable a shaded blue area, check the Shaded Area box. To display only a blue outline without the shaded area, uncheck the Shaded Area box.

Frequency Range Select the amplitude of the frequency interval to be scanned from the Frequency Range drop-down list. Available frequencies are device-dependent. There are pre-defined ranges for the most popular bands. You can enter a custom range; select Custom Range from the Frequency Range drop-down list and enter the desired values in the Start and End fields.
