4.6 Wireless Operation The M4-2000 point-to-point wireless communication system consists of a primary unit and a secondary unit. They operate in a master / slave relationship, with the primary unit responsible for establishing Time Division Duplex (TDD) link timing while the secondary unit locks onto the downlink in order to synchronize the uplink properly. The TDD frame duration is 1 ms, divided into separate uplink and downlink subframes. When the link starts, the ratio between uplink and and downlink is 50-50; once communication is established the ratio will change to either a configured fixed setting or else dynamically adapt to optimize for the throughput observed in each direction. The TDD ratio ranges from 30% downlink to 70% downlink, in increments of 1%. The overall 1 ms TDD frame size results in low data transfer latency. The system can operate over channel bandwidths of 10, 20 or 40MHz. 4.6.1 Carrier Aggregation The M4-2000 system features carrier aggregation where two radios combine seamlessly into a single, large data pipe. The radios can operate in the same or different bands, licensed or unlicensed, but are required to use the same channel bandwidth and TDD ratio. Each radio has separately configured transmit and receive frequencies. Normal configuration is a single frequency for radio 1, and a separate frequency for radio 2. Kwikbit M4-2000 User Guide Confidential & Proprietary

M4-2000 User Guide However, each radio can split the channel into separate downlink and uplink frequencies. This hybrid mode maintains the TDD channel turn-around alternating between uplink and downlink, but also alternates the transmit frequency between uplink and downlink. Each of the dual radios is capable of hybrid TDD operation, with independently configured Transmit and Receive frequencies for each radio. Bearer plane data is always distributed evenly between the two radios. 4.6.2 MIMO / XPIC operation Each radio in the M4-2000 system operates in Cross Polarization Interference Canceling (XPIC) mode with dual data streams doubling the channel capacity. 4.6.3 Adaptive modulation and coding Each M4-2000 unit adapts its modulation and coding level to maximize data throughput based on received signal quality. Each receiver evaluates signal quality by measuring signal strength, signal to noise ratio, and the rate of corrected bit errors. The receiver feeds this information back over the air to its peer transmitter to optimize the modulation level used. The MCS level is continually adjusted on 1ms frame boundaries. The system automatically switches between nine modulation and coding modes, indicated by number as shown Level Modulation /

M4-2000s header compressor examines ingress packet flows and removes Ethernet and IP header bytes from continuous flows. The header de-compressor at the receiver then restores headers using previously cached values. The header compression feature provides the following link enhancements:
Ingress packet classification determines compression profile (example: IPV4, IPV6) Within each profile, flows are assigned a compression context. A new context is automatically established and runs as long as the flow is present. The context is discarded when the flow ends Up to 1024 contexts are supported Compression efficiency will vary. Best case:

Configure radio 1 (on both primary and secondary nodes) with DL (downlink) and UL (uplink) frequency. On the primary node, the term Downlink refers to the radio transmitter, whereas on the secondary node the Downlink configuration applies to the radio receiver. Use of the terms Downlink and Uplink (instead of transmit and receive) means both nodes share the same frequency configuration making it easier to compare configurations or switch roles. Both primary and secondary nodes must have the same configuration for Radio 1 DL and UL frequencies in order for the link to connect. Radio 1 frequency configuration is referred to as the hailing channel, and serves as the starting point whenever either node restarts, or the link fails for any reason. If Dynamic Channel Selection is enabled (DCS described in a subsequent section) radio 1 will potentially move to alternate frequencies after its started. However the link will always start with radio 1 on the hailing channel. If DCS is disabled, then of course Radio 1 will remain on the hailing channel. Unless you are working around a specific known interference issue at one location, its reasonable to use a single frequency for both DL and UL. The frequency configuration is visible on the Web UI via Configure Radio Link Radio 1 L Frequency, UL Frequency Kwikbit M4-2000 User Guide Confidential & Proprietary

M4-2000 User Guide The corresponding SNMP configuration variables are in the first row of the cfg58RadioTable, the variables are cfg58RadioDLFrequency.1 and cfg58RadioULFrequency.1 The frequency value is entered as kHz with a resolution of 100 kHz. The allowed range for radio 1 is show in the following table:
channel bandwidth 10 MHz 20 MHz 40 MHz U-NII-1 band U-NII-3 band 5160000 : 5245000 5735000 : 5845000 5160000 : 5240000 5735000 : 5840000 5190000 : 5230000 5755000 : 5830000 The radio frequency as configured will take effect when the link is started. After changing the frequency, you must manually restart the link in order to trigger the new configuration setting to take effect. For radio 1, the frequency must be configured on both the primary and secondary nodes. Once changed, both nodes thus require an administrative restart in order for the new configuration to take effect. Take special care to restart the remote end of the link first, before resetting the local end, in order to maintain connection over-the-air to the remote end. Note that a loss of the link, due to RF path obstruction for example, and subsequent recovery will not trigger a configuration refresh; it is triggered only via administrative link toggle. Link Toggle Administrative toggle of the link (that is, turn it off, then on again) is required for various changes of configuration. Link toggle is automatic when changing frequencies via the Web UI. When the submit button is pressed, the link will automatically be stopped, then started. Make sure to modify the remote end prior to changing the local end; that is, to change the hailing channel set it first on the secondary node at the remote end of the link and hit submit. At this point, the changes will take effect and the link will go down (since the frequencies on the secondary node no longer match the primary node). Then change the local primary node and hit submit. When the changes take effect, the link will be re-established. Using an SNMP management station, the link toggle is accomplished via setting the following:
m4gNlosPtpControlAirlink.0 = restart Other Radio 1 configuration In addition to radio 1 frequencies, both primary and secondary nodes must be properly configured for Radio 1 Antenna Mode and Channel Bandwidth. Antenna mode configuration is visible on the Web UI via:
Configure Radio Link Radio 1 Antenna Configuration Kwikbit M4-2000 User Guide Confidential & Proprietary
- 22 -
Channel Bandwidth is found under M4-2000 User Guide Configure Radio Link Link Features Radio Channel Bandwidth The corresponding SNMP variables are:
cfg58RadioAntennaMode.1 m4gNlosPtpCfgGenChannelBandwidth.0 Configured vs active frequencies If the DL and UL frequencies are changed when the link is already running, then the currently running frequencies will not match the pending active configuration. To observe note the Web GUI top panel always shows the currently running set of frequencies, whereas the panel Configure Radio Link Radio 1 DL Frequency, UL Frequency shows the configured values. The SNMP status values for the currently operating frequencies are found in the m4gNlosPtpDevStatusRadioLinkTable, the variables are rltDLFrequency.1 and rltULFrequency.1 Frequency configuration errors If a radio 1 frequency configuration error is discovered when the link is started, the status of radio 1 will show 0 as the operating frequency, and the link will not start. For example, suppose the channel bandwidth is 10 MHz and the DL Frequency is 5170000. If the channel bandwidth is subsequently changed to 40 MHz, the DL Frequency setting will become out-of-bounds, since the lowest center frequency of a 40 MHz channel bandwidth is 5190000. The SNMP status in m4gNlosPtpDevStatusRadioLinkTable, rltDLFrequency.1 will show a value of 0, which indicates the error. Likewise, the top banner of the Web UI will show the Radio1 Tx frequency 0.000, also indicating an unacceptable value. To correct, set the frequency to a valid value, say 5200000, restart the link and the DevStatusRadioLinkTable value will show the corrected value, likewise the top banner of the Web UI will show the corrected value and the link connected. 4.6.6 Configuration of Radio 2 Frequencies The M4-2000 is a dual radio system whereby radio 1 always performs initial link establishment, and then initiates a second link using Radio 2. The primary node always uses the initial Radio 1 connection to communicate the frequencies to be used by Radio 2. To configure the starting frequencies for Radio 2, it is only necessary to configure the DL and UL Frequency values on the primary node. Once the Radio 1 link is established, the Radio 2 configuration is interpreted by the primary node and used to set up radio 2 link. Kwikbit M4-2000 User Guide Confidential & Proprietary
- 23 -
M4-2000 User Guide If the configuration is invalid for any reason (out of range or overlapping the first radio for example), the primary node will automatically adjust to an appropriate frequency. If this occurs, you may note that the current operating frequency for Radio 2 differs from its configuration. Configure the Radio 2 frequency on the primary node via the Web UI:
Configure Radio Link Radio 2 DL Frequency, UL Frequency Note on the remote node these fields are greyed out. Values that may appear are not relevant. The corresponding SNMP configuration variables are in the second row of the cfg58RadioTable, the variables are cfg58RadioDLFrequency.2 and cfg58RadioULFrequency.2 Likewise, on the secondary node these variables exist but they are ignored as long as the node is configured as a secondary node; the radio 2 frequencies are always controlled by the primary node. 4.6.7 Dynamic Channel Selection The M4-2000 system features an advanced interference avoidance feature. Known as Dynamic Channel Selection (DCS), this feature automatically hops the radio away from a degraded frequency and selects the best available alternate frequency. Switching frequencies is quick with very little or no packet loss over the link. In the background, the system periodically scans across the channel plan to measure the signal level at each plan center frequency. The resultant accumulation of frequency observation data insures selection of the optimal frequency when a channel hop is necessary. The system can select different channels for uplink and downlink (i.e., F-TDD) to avoid localized intereference on either side of the link. To enable DCS, on the primary node Web UI select Configure Radio Link Link Features DCS Mode enabled The corresponding SNMP variable is m4gNlosPtpCfgPriEnableDCS.0 Changes to the EnableDCS parameter will take place immediately. The operational details of DCS follow. Channel Plan The channel plan file contains a list of channel numbers and center frequencies that partition the 5.8 GHz band into a set of operational center frequencies. DCS operation depends on the channel plan in order to make background RSSI measurements on plan frequencies. These measurements are the basis by which the system selects an optimal frequency. Configure the channel plan filename via Web UI:
Configure Radio Link Dynamic Channel Selection Available Channel Plans The corresponding SNMP configuration variable is cfg58RadioChannelFileName.0 Kwikbit M4-2000 User Guide Confidential & Proprietary
- 24 -
M4-2000 User Guide Channel Plan filenames must end with .cpx extension. The search path for Channel Plan files is:
/etc/m4g/58_cfg/
/etc/m4g/58_cfg_local/
By default, the filename is default_plan.cpx. If you want to create a custom channel plan file, use the default as a template. Rename the file
(keeping the cpx extension) and copy your custom channel plan into the directory 58_cfg_local in order to prevent subsequent software updates from disturbing your custom plan file. Channels defined in a plan must have non-overlapping frequencies. There are separate sections in the plan file for channel bandwidths of 10, 20 and 40 MHz. The primary and secondary nodes must be configured with the same channel plan file. The system reads and processes the channel plan file only at system boot. Therefore, after a change to the channel plan file, reboot the system for the new plan to take effect. When DCS mode is enabled, the sytem is restricted to operation on plan frequencies because background monitoring of interference occurs only on plan frequencies. However, the Radio 1 hailing channel configuration is not restricted to plan frequencies. Therefore, after the link initially comes up on the hailing channel, and prior to full DCS operation, the system will hop from the configured hailing channel to the nearest plan frequency. Radio 2 configuration likewise is affected by DCS operation. If Radio 2 is configured to a non-plan frequency, when DCS is enabled the system will automaticically start Radio 2 on the nearest plan frequency. Runtime change to EnableDCS If EnableDCS is changed from disable enable at run time, when the airlink is up, the system will immediately hop radio 1 to the nearest plan frequency, then hop radio 2 to the nearest plan frequency, and then begin DCS operation. If EnableDCS is subsequency changed back from enable disable, the system will simply cease DCS operations, it will not revert the currently operating frequencies back to their previous values. Of course, if the airlink is stopped then started it will always start on the hailing frequency. DCS Operation Dynamic Channel Selection involves the following elements background measurement over plan frequencies of received signals monitoring the current airlink for signal quality hopping away from a degraded channel onto an alternate channel when required Background measurements are displayed via the Web UI via Monitor Spectrum Background Noise The graph shows a relative signal level of noise and/or interference. DCS Operation: background measurements Kwikbit M4-2000 User Guide Confidential & Proprietary
- 25 -
M4-2000 User Guide The background monitor operates by iterating over the channel plan and collecting a signal measurement for each frequency. The background monitor very briefly tunes the radios to the target frequency, listens just long enough to collect a measurement, and then resumes operation on the current frequency. These ongoing measurements create small gaps in the bearer plane which effectively consume a small percentage of the airlink, reducing available bandwidth and slightly increasing maximum latency. The background monitor operates at a rate controlled via the parameter m4gNlosPtpCfgPriBandRefresh.0 BandRefresh can be set to low, medium, or high. Select the rate that provides the optimal trade-off between the amount of gap time introduced (and the resultant loss of airlink capacity) and the time required to refresh the measurements over the entire channel plan. A setting of low consumes approximately 1% of the airlink and will refresh the entire channel plan in about 20 seconds; a setting of high will consume approximately 4% of the bandwidth while refreshing the channel plan in about 5 seconds. Normally low should be sufficient, the high band refresh is intended to address highly varying interference environments where more rapid measurement accumulation may provide improved channel selection when hopping around. DCS Operation: airlink quality optimization Whenever DCS is enabled the airlink quality is continually monitored. If the link degrades sufficiently, (triggered by a drop in MCS level to below 2,) the system will quickly hop to an alternate channel. A channel hop may also be triggered when some alternate channel remains sufficiently better
(approximately 9 db lower background RSSI measurement value) over some period (approximately 5 measurement periods) compared to the current channel. 4.7 Ethernet operation The M4-2000 system utilizes Gbit Ethernet interfaces for customer data network(s) and the management data network. On each M4-2000 unit there are two RJ45 connectors for customer data and one RJ45 connector for the management LAN. The unit operates with an internal, managed layer 2 switch where the management interface is preprogrammed to connect to the internal IP stack of the device itself. This connection is used for operation, configuration and management of the device. 4.7.1 Customer Data Network The Ethernet traffic of the three data interfaces is switched over the airlink to the remote unit based on configured internal switch options. Following are highlighted features of the integrated switch capabilities:
2,048 byte jumbo frame support 8K MAC addresses QoS o 4 queues per port o 802.1p, port, TOS/DS, IPv6, TC, MAC o Programmable QoS Weighting Kwikbit M4-2000 User Guide Confidential & Proprietary

This management agent is IP addressable with in-band and out-of-band interfaces. The default IP address is 192.168.0.51. If the programmed IP address is lost, it can be reprogrammed using the serial interface by an authorized service technician. The management interface can be configured to transmit and receive either VLAN tagged, untagged, or unmodified Ethernet frames. The management agent can be connected with standard network management protocols including SNMPv3, web http, web https, CLI, ssh, and syslog. The SNMPv3 MIB defines the canonical management information database. The proprietary M4-2000 MIB contains device configuration, status and statistics information. It also defines device notification alarms. 4.7.2.1 Web-Based Management The M4-2000 units management system includes a web server. This provides a convenient way to configure and operate the equipment from a locally connected device (Ethernet or Wi-Fi) or a management station on the management network. Management traffic to remote units is bridged over the air, which provides an easy and secure method to manage both sides of the link. The web agent provides status, configuration, statistics and security functions that are organized into the following sections:
Main/Home: summary of unit status, performance and configuration information Monitor: short and longterm statistics graphs for the unit throughput, RSSI, CINR, packet rate, header compression and temperature Configure: separate pages for general unit configuration, radio link configuration, IP configuration, L2 switch configuration (including, ports, VLAN and QoS), and time source configuration Fault Isolation: SNMP alarms and syslog view Security: user security settings for management access Administration: configuration backup and upload, as well as unit software upgrade features Kwikbit M4-2000 User Guide Confidential & Proprietary

5.1.4 Installer Link Setup Tool M4-2000 User Guide In addition to the full management console, each M4-2000 unit hosts a Link Setup Meter page optimized for mobile devices. The simplified interface, showing the real-time link score for each radio, enables installers to align links rapidly. The link score aggegates RSSI, SINR, and CRC error rate into a link quality metric that ranges from 0 to 100. The objective of link alignment is simply to position the device to maximize the score: higher score is better. Advanced users can view SINR, MCS and CRC errors. In order to use the Link Setup Meter, connect to the management port and point your browser at the unit. On the initial page, simply select launch of the link setup meter on the bottom of the page, no login is required. 5.1.5 M4-2000 Physical Installation Select a mounting location for the M4-2000 unit that permits easy adjustment of its vertical and horizontal orientation and, at the same time, allows for cable connectivity and management.

A PoE injector needs to be installed in-line with the Management or Data network cables connected to one of these ports as shown. Make sure that the length of the Ethernet cable between the unit and the injection point does not exceed 30 meters. 5.1.6 Aligning Link Antenna Before performing the units antenna alignment for optimal link performance, make sure you have completed the physical installation procedure for the units on both sides of the link. If the pre-
configuration tasks were not performed prior to physical installation of the units, perform the pre-
configuration tasks before proceeding with the alignment procedure. 1. Power up the units on both sides of the link. The PWR indicator light on both units should be illuminated green. The primary unit will begin broadcasting signal and the secondary unit will enter receiving mode, attempting to obtain signal. The main page on the web management interface will reflect this state and the LNK indicator light on the unit will start blinking green. Once the radio link and data connection is established, the LNK light becomes continuously lit. Observe the LEDs to determine initial connectivity between the units when performing next steps. Table 3.4.5 details the states indicated by LED activity. 2. At each side of the link adjust the units to point towards the unit at the other side of the link. Use a compass or other tool to perform this task Kwikbit M4-2000 User Guide Confidential & Proprietary

M4-2000 User Guide 3. Without moving the Primary unit, adjust the azimuth and elevation angle of the Secondary unit for maximum link quality. Link quality is to be monitored via a units Link Setup Meter as described in the previous section 4. Without moving the Secondary unit adjust the azimuth and elevation angle of the Primary unit for maximum link score 5. Repeat steps 3 and 4 to fine tune the alignment. Note: If the installation is in a complete NLoS situation, repeat the alignment process by pointing the Primary antenna in different directions for maximum CINR reading on the Secondary unit. 6. Once the alignment process is complete and the best signal quality is achieved, secure the Primary and Secondary units by tightening the mounting screws 5.2 System configuration After the Primary and the Secondary units are preconfigured and installed, connect to both units from a Management PC on the Management network. The Management PC needs to have an IP address on the Management network to be able to communicate through the pre-configured Management IP gateway. To verify connectivity from a terminal window, issue the ping command as follows:
ping [M4-2000 units assigned IP address]
Once connectivity is established, open a browser window on the Management PC and enter the target units IP address in the URL field. On the Login page enter the pre-configured Name and Password. The Main management page will open, which provides a summary of unit status, state and configuration information. To further configure the unit, follow the configuration pages from the main menu on the left side of the Main page. Please see Section 6 for configuration options. Following configuration of the Primary unit, connect to the Secondary (remote) unit by entering its IP address in the URL address field. Note that in order to be able to connect to the remote unit management over the airlink, pre-configuration step 17 in section 4.1.3 must have been performed.
