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 both the 5.2 and 5.7 bands and in both 10 and 20 Mbps. 5.7
backhauls can be used with reflectors on either or both ends. 5.2 backhauls cannot be used with
reflectors in the US or Canada due to regulatory agency restrictions.

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 data needs
and range needs. 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 is a 5200 and vice versa. While distance separation of
100 vertical feet (30 m) on a tower can allow use of co-located APs and BHs in the same band,
choosing cross-band APs and BHs is usually the better choice.
