    Canopy 400 Series OFDM AP and SM User Guide 3 Planning Canopy 400 Series products use a 10 MHz channel size configurable on 5 MHz centers. This channel size, along with some different characteristics due to the use OFDM carrier technology and QPSK, 16 QAM, or 64 QAM modulation, supports somewhat different channel planning than for standard Canopy.

WEATHER RADAR Spectrum between 5600 and 5650 MHz (sometimes called the “weather notch”) is used by some weather radar and is not allowed for use by regulations in some regions, including Canada and, for new equipment, Europe.

    Canopy 400 Series OFDM AP and SM User Guide 3.5.2 Frame Calculations and Configuration Settings Interference between collocated Canopy systems can be avoided by following two practices: 1. Use a CMM. This synchronizes frame start, so that all collocated APs begin transmitting at the same time each 2.5 millisecond frame.

    Canopy 400 Series OFDM AP and SM User Guide GHz band because the regulations are for spectral power density and with half the channel size (10 MHz vs 20 MHz), Canopy OFDM is allowed half the power (27 dBm vs 30 dBm). To meet 27 dBm EIRP with the 17 dBi antenna that comes with the 5400AP, the maximum setting allowed is 10 dBm (the default) since 27-17=10.

  • Page 19: Table 4: Release 8.4 Operation Based On Region Code

    Canopy 400 Series OFDM AP and SM User Guide 4.4.1 Background and Operation The modules use region-specific DFS based on a new “Region Code” selected on the module’s “Configuration => General” page. By directing installers and technicians to set the Region Code correctly, the operator gains confidence the module is operating according to national or regional regulations, without having to deal with the details for each region.

  • Page 21

    Canopy 400 Series OFDM AP and SM User Guide IMPORTANT! Operators under regulatory requirements for DFS must ensure the new Canopy parameter “Region Code” is set correctly. This applies to initial configuration, after a module is reset to factory defaults, or after a module is upgraded.

    Canopy 400 Series OFDM AP and SM User Guide An SM has both a configurable Region Code and, once it registers to an AP, an active Region Code. After an SM registers to an AP, it uses the Region of the AP to determine its DFS behavior and displays the AP’s Region Code on its Home =>...

  • Page 30: Figure 9: Ground Lug Highlighted On Ap

    Canopy 400 Series OFDM AP and SM User Guide Figure 9: Ground lug highlighted on AP Unlike standard Canopy APs, the Canopy 400 Series AP have metal-to-metal contact from the tower or support structure, through the antenna, through the coax cable, to the radio. Due to this, to provide the best protection from near lightning hits, it is strongly recommended to install surge suppression at the AP.

    Canopy 400 Series OFDM AP and SM User Guide The Canopy 400 Series SM has a ground/Protective Earth lug, just like the AP. Although not as critical as in the case of the AP (where there is metal-to-metal connectivity through the coax and antenna to ground), the lug can be used to ground the SM for additional protection.
