PRODUCT DESCRIPTION
Canopy Backhaul
Backhaul links provide point-to-point connectivity either as a standalone link or feeding an Access
Point cluster as part of a Canopy network.
Backhaul modules are available in 2.4, 5.2, and 5.7 bands and in both 10 and 20 Mbps. 2.4 and
5.7 backhauls can be used with reflectors on either or both ends. Regular 5.2 backhauls cannot be
used with reflectors in the US or Canada due to regulatory agency restrictions. Extended Range
(ER) 5.2 Backhauls have very low transmit power and it is recommended to use reflectors at both
ends.
The following table shows typical ranges for each type of backhaul.

When using Backhauls in standalone links, the type of Backhaul is selected based on RF
environment, throughput, and range needed. When using Backhauls in a network and co-locating a
BH with Access Points, the type of backhaul is usually selected based on having the BH in a
different band than the APs. In other words, if the APs are 5700s, the BH could be a 5200 or a
2400. If the APs are 2400s, the BH could be a 5200 or a 5700. While distance separation of 100
vertical feet (30 m) on a tower can allow co-locating APs and BHs from the same band, choosing
cross-band APs and BHs is usually the better choice.
