3.2 COLLOCATION OF 5.8 GHZ OFDM WITH STANDARD 5.7 GHZ CANOPY FSK When locating Cyclone OFDM (5.8 GHz) APs near 5.7 GHz standard Canopy FSK APs (especially on the same tower, but also in the same geographical area), the following practices should be followed to avoid interference between the two systems: Plan spacing between OFDM and FSK channels to provide 25 MHz center spacing, which gives a 10 MHz guard band between the 10 MHz OFDM channel and the 20 MHz FSK channel.
The syste em chooses its operation ra ate dynamica ally, based on Canopy’s intternal ARQ (A Automatic Repeat re eQuest) error control metho od. With ARQ Q, every data slot of every frame sent ovver the air (exxcept downlink broadcast) is expected to be acknowled dged by the re eceiver, and if acknowledg gement is nott received, the data is re esent. The sending unit mo onitors these resends, and adjusts the o operation rate e gly.
4.2 TRANSMITTER OUTPUT POWER (AND NO JITTER) The AP/BHM’s Transmitter Output Power is configured on the AP/BHM’s “Configuration => Radio” page. Radio Frequency Transmit Output Power Range Factory Default Setting Cyclone OFDM 5.7 GHz 5.8 GHz -30 dBm to +20 dBm (US) -30 dBm to +21 dBm (Outside US) 10 dBm In most regulatory regions, including the US, Canada, and Europe, Cyclone 5700-360.OFDM Series modules operating in the 5.

Figure 3: Max Range & Downlink Data on AP "Configuratiion => Radio ot settings as a function of number of SM Ms in the secttor are shown n in Table 3.
Control Slots are reserved for SMs’ bandwidth requests and never handle data. A higher number of control slots gives higher probability that an SM’s bandwidth request will be heard when the system is heavily loaded, but with the tradeoff that sector capacity is reduced by about 100 kbps for each Control Slot configured, so there will be less capacity to handle the request. Uplink Data Slots are used first for data.
After an AP A or BHM with DFS boots s it performs a channel ava ailability checkk on its main carrier freque ency for 1 minu ute, monitoring for the rada ar signature without w transm mitting. If no ra adar signature is detected during this s minute, the module then proceeds to normal beaco on transmit m mode. If it doess detect a rad dar signature,, the frequenc cy is marked for f a 30 minute non-occup pancy period, and the module moves to its 1st alterna ate carrier freq quency.
8: Active Reg gion Code on n SM Home => = General S Status page Figure 28 The AP or BHM always s operates un nder its manually configure ed Region Co ode (the one o on the Configura ation => Gene eral page), and so does no ot show a Reg gion Code on its Home => General Stattus page. Under norrmal operations, APs and BHMs operatting with DFS (see Table 4 4) will experience an additional minute aftter power-up or reboot beffore they will register r any S SMs or BHSs .
If radar is detected on the main frequency, either at startup or during operation, a Channel Availability Check will be performed on the 1st alternate frequency before it is then used for transmission. If radar is detected on the 1st alternate frequency, either during Channel Availability Check or during operation, a Channel Availability Check will be performed on the 2nd alternate frequency before it is then used for transmission.
Cyclone 5700-360.OFDM Series radios use FEC (Forward Error Correction) to extend the range of the modules. They use Reed-Solomon error correction optimized at 3/4 coding. The coding rate is not settable by the operator. 4.8 CYCLIC PREFIX (CONFIGURABLE ONLY ON CYCLONE OFDM AP/SM) OFDM technology uses a cyclic prefix, where a portion of the end of a symbol (slot) is repeated at the beginning of the symbol (slot) to allow multi-pathing to settle before receiving the desired data.
Installing an AP typically consists of four phases: 1. Configuring the AP at an operator's facility or at the installation site using the information and settings defined previously in Planning (Section 3) and Configuring (Section 4). 2. Assembling the AP (radio and antenna and brackets) and physically installing it using on the mounting structure. 3. Cabling the AP to the CMMmicro or CMM4 (for Cyclone OFDM APs), and grounding it to Protective Earth – PE using Procedure 4.
