3G Wireless WAN Interface Cards REVIEW DRAFT-CISCO CONFIDENTIAL Related Documentation For more information about connecting the 3G-ANTM-1919D to the HWIC-3G-GSM or HWIC-3G-CDMA, see the Cisco Multiband Swivel Mount Dipole Antenna (3G-ANTM1919D) document. For more information about connecting the 3G-ANTM1916-CM to the HWIC-3G-GSM or HWIC-3G-CDMA, see the Cisco Multiband Omnidirectional Ceiling Mount Antenna (3G-ANTM1916-CM) document. Faceplate-Mounted and Ceiling-Mounted Antennas and Cabling Depending on the wireless environment, wall-mounted or ceiling-mounted antennas may be preferred for optimum radio coverage. If the length of the coaxial antenna cable is insufficient to cover the distance between the 3G wireless HWIC and the location of the installed antenna, you can use ultra-low-loss TNC extension cables between the 3G wireless HWIC and the antenna cable. RF energy is carried between the antennas and the radio equipment through a coaxial cable. An antenna cable introduces signal loss in the antenna system for both the transmitter and the receiver. Although the cable run can be 100 feet (30 m) or more from the 3G wireless HWIC to antenna locations, the longer the cable run, the greater the signal loss. To reduce signal loss, minimize the cable length and use only ultra-low-loss antenna cables to connect radio devices to antennas. To connect faceplate-mounted or ceiling-mounted antennas, follow the installation instructions for your antenna: • For more information about connecting the 3G-ANTM1919D to the HWIC, see the Cisco Multiband Swivel Mount Dipole Antenna (3G-ANTM1919D) document. • For more information about connecting the 3G-ANT1916-CM to the HWIC, see the Cisco Multiband Omnidirectional Ceiling Mount Antenna (3G-ANTM1916-CM) document. • For more information about connecting the 3G-AE015-R the HWIC, see the Cisco Extended Antenna Base (3G-AE015-R) document.
