Canopy 30/60 and 150/300 Mbps OFDM Backhaul Radios - Differences:
The differences between the OFDM Backhaul Radios provide the operator with a selection of choices
based on features, bandwidth requirements and price points to cost effectively establish a long range LoS
or a challenging nLoS or NLoS wireless link. The OFDM Backhaul radios primary feature differences are:
• Hardware
- 30/60 and 150/300 use different hardware (electronics)
- No difference in hardware between 30 Mbps BH and 60 Mbps BH
- No difference in hardware between 150 Mbps BH and 300 Mbps BH
• Software
- Maximum bandwidth of 30/60 Radios determined by software key; a 30 Mb BH can be
easily upgraded to a 60 Mbps BH
- Maximum bandwidth of 150/300 Radios determined by software key; a 150 Mb BH can
be easily upgraded to a 300 Mbps BH
- 30/60 and 150/300 run on entirely different software
• Power Supply - one key difference between the 30/60 power supply and the 150/300 power supply:
- 150/300 Mbps BH PIDU powers the radio over CAT 5e 1000Base-T Gigabit Ethernet
- 30/60 Mbps BH PIDU powers the radio over CAT5e 100Base-T Ethernet

• Spectrum
- 30/60 Mbps BH uses 12MHz of spectrum
- 150/300 Mbps BH uses 30MHz of spectrum.
• Modulation
- 30/60 Mbps BH ranges from BPSK to 64QAM
- 150/300 Mbps BH ranges from BPSK to 256QAM
• T1/E1 Capability
- 30/60 Mbps BH must be paired with a T1/E1 Multiplexer; it has a TDM Mode software
feature that generates a new set of Adaptive Modulation margins which reduces the
probability of codeword errors (and hence packet loss).
- 150/300 Mbps BH has built in T1/E1 port in the radio. 150 Mbps BH has one built-in
T1/E1 port and 300 Mbps BH has two. The 150/300 Mbps BH can also be paired with a
T1/E1 Multiplexer t to transport voice.
• Fiber Option
- The 150/300 Mbps BH has an optional fiber conversion kit (see page 17 for details).
• WiMAX Spectrum Management Control for 150/300 Mb BH
- 30/60 Mb BH includes two Spectrum Management Options
- 150/300 Mb BH includes three Spectrum Management Options
- Explanation of three options:
 DFS – Dynamic Frequency Selection continually monitors the 5.7GHz spectrum
looking for the channel with the lowest level of on channel and co-channel
interference.
 Fixed Channel – Fixed frequency mode allows the installer to fix transmit and
receive frequencies on the radio.
 WiMAX – WiMAX mode allows the installer to assign WiMAX compatible
channelisations. An additional side effect of configuring the WiMAX mode is to
enable the WiMAX SNMP MIB support.
