3.5.4 IDF Access Point Planning

MobileAccess recommends that each independent IDF Telecom closet is adequately planned for

installation of the access points to increase the amount of isolation and reduce the amount of RF

leakage between access points.

MobileAccess recommends the following options for access point installation:

• Wall Mounting of MobileAccess supported Access Point

• Rack-Mounting of MobileAccess supported Access Points

Utilizing the mounting hardware distributed from each supported access point vendor, Access

point can be mounted on a wall within the IDF or telecom closet and connected with the

appropriate low-loss jumper cables to the appropriate 860 WLAN module interface ports.

MobileAccess has also found that mounting the access points in a 19” rack system has proven to

be effective against RF leakage between access points. In this configuration,

two access points

can be installed per 19” shelving unit which takes up 1U of space per two access points.
