Book Title
Caution
Install the HWIC and any antennas away from appliances that share the same frequency bands.
Microwave ovens, cordless telephones, and security monitors can temporarily interfere with wireless
performance.
Caution
We recommend avoiding installing wireless antennas in or near rack-mounted equipment that include
networking equipment and computer servers whose radiated noise emissions can severely degrade radio
performance.
To extend the coaxial cable included with your antenna base, we recommend a ULL coaxial cable for
flexibility of installation without significant loss of range.
Table 2
provides insertion loss information about ULL extension coaxial cables available from Cisco.

shows the ULL cable recommended for Cisco 3G Wireless WAN HWICs.
