Connecting Radio Antennas to the Access Point HWIC
This section contains information about connecting the radio antennas.
Note
Before connecting the radio antennas, install the access point HWIC in the router. See
Installing Cisco
Interface Cards in Cisco Access Routers
for more information.
In addition to antenna orientation, wireless access point installation location with respect to all wireless
clients plays a significant role in determining overall network performance. Clients at the furthest
coverage points might have 10% to 50% of the bandwidth of clients close to it. Wireless network
coverage in one area or location might need to be lowered to improve the performance of other clients.
Because antennas transmit and receive radio signals, their performance can be adversely affected by the
surrounding environment including distance between access point and client, physical obstructions, or
radio frequency (RF) interference.
Follow these guidelines to ensure the best possible performance:
•
Wherever possible, mount the access point HWIC and antenna where the wireless devices would be
within sight and avoid physical obstructions. Barriers along the line of sight between client and
access point will degrade the wireless radio signals. access point HWICs and antennas can be
installed above floor level in office environments or near the ceiling for better performance since
most obstructions tend to be near floor level.
