Getting Started: Initial PMP Link Setup, Requisite AP Configuration



The default IP of 450 platform modules is

Quick link setup – requisite AP configuration

The Canopy system consists of a family of highly flexible fixed wireless access devices that can be put into service very quickly and with a minimal configuration.  Follow the procedure below to configure an AP for management access and SM registration:


Ensure that the module is powered on and that an Ethernet cable is connected from the accessing device to the power supply data port.  The accessing device must be configured with and IP address in the subnet.

Configure your Region and Country of operation

To comply with various international regulations, a region setting is required. This unit will NOT transmit unless a valid region code is set. Please select your region code from the drop down menu. If your region does not appear, then select "Other".

This parameter automatically implements frequency band range restrictions for the selected region. Units shipped to regions other than the United States must be configured with the corresponding Region Code to comply with local regulatory requirements.

Configure the Carrier Frequency

This field indicates the current operating center frequency, in MHz.

To communicate, each Access Point (AP) and Backhaul (BH) timing master must be assigned a specific carrier frequency. By default, this frequency is not set at the factory to ensure that new units do not accidentally transmit on an unintended frequency. For our purposes, frequency selection for OFDM platforms has two basic rules:

Two radios located at a single location (such as an AP cluster) and on the same frequency should not have an overlapping pattern.

Generally, for PMP 450, no guard band is needed. With the exception of 3.5/3.65 GHz platform, which can also operate with no guard band if "Adjacent Channel Support" is enabled. Otherwise 3.5/3.65 will need a guard band of 5/3/2 MHz for 20/10/5 MHz channel bandwidths. For PMP 430 and PTP 230, 5/5/2.5 MHz guard band is required for 20/10/5 MHz channels bandwidths.

We recommend multipoint AP clusters use frequencies separated by 15 MHz where convenient. For a 360 degree multipoint AP, each frequency is used twice with the back-to-back units sharing the same frequency.



Configure the Channel Bandwidth

Channel bandwidth is the channel size used by the radio for RF transmission. The setting for the channel bandwidth must match between the AP and the SM. You can choose between 5/7/10/15/20/30 MHz bandwidth whichever applicable for the model.



Configure the Frame Period

The frame period determines the length of the TDD time slot in milliseconds. You can choose between 2.5 and 5ms frame period.

The 5ms frame period configuration provides higher throughput as a result of reduced frame overhead during transmission. In turn, the 2.5 ms frame period configuration affords reduced latency in the system, half of that introduced by the 5 ms frame configuration.



Configure the Color Code

For registration to occur, the color code of the SM and the AP must match. Color code is not a security feature. Instead, color code is a management feature, typically for assigning each sector a different color code. Color code allows you to force a SM to register to only a specific AP, even where the SM can communicate with multiple APs.

Select the Synchronization source

When any radio transmits, it radiates energy. If a nearby radio is trying to receive at the same time another is transmitting, interference can result. One of the mechanisms used by Canopy to avoid this issue is to synchronize all transmissions. This approach ensures that all Canopy units will transmit and receive during the same time interval.

To accomplish this, Canopy Cluster Management Module's (CMM) each contain a GPS receiver. This receiver is used to create a precision timing signal which is then used by the attached APs/BHs (Backhauls). For systems that have only one AP/BH, this signal can be generated by selecting "Generate Sync" which causes AP/BH to use a simulated synchronization. For systems that have multiple APs/BHs, GPS synchronization should be used.

Each AP or BH timing master (BHM) must be programmed to either generate its own synchronization pulse (for single AP/BHM use only) or to use an external pulse. If you are using a CMM or other source of synchronization timing, you should select "AutoSync"; if not, you should select "Generate Sync". There are three methods on the AP/BHM from which the synchronization is received:
1)Power Port (Not applicable for PTP450)
2)Timing Port
3)On-board GPS (PMP 450 AP only)
If the power port is being used, only one cable is necessary to obtain power and the synchronization pulse. If the timing port is used, two cables will be necessary, one to obtain power and the other for the synchronization pulse.

Selecting "AutoSync + Free Run" will allow the AP/BHM to continue to transmit even after the sync pulse is lost. Otherwise if "AutoSync" is selected and synchronization pulse is lost, the AP/BHM will immediately stop transmitting. This is done to prevent interference with other Canopy systems.

Please be aware that operating multiple APs/BHs without an external GPS timing source may lead to degraded system operation.

Also, use the Frame Calculator tool for complete transmit and receive synchronization across different Canopy products.

Configure the LAN1 Network Configuration

The IP address of the Canopy AP/BH timing master is used to talk to the unit in order to monitor, update, and manage the Canopy system. If you are viewing this page (which you appear to be doing now), your browser is communicating with the Canopy AP/BH using this IP address.

Each network has its own collection of IP addresses that are used to route traffic between network elements such as APs, BHs, Routers, and Computers. You need to select the IP address, Default Gateway, and Network Mask which you intend to use to communicate with the AP/BH timing master in the space below.

If you don't know what these are, please consult your local network specialist.

Configure SNMP Settings

Operators may use SNMP commands to set configuration parameters and retrieve data from the AP and SM modules. Also, if enabled, when an event occurs, the SNMP agent on the 450 Platform Family sends a trap to whatever SNMP trap receivers configured in the management network.
