The options I have found for these 3G cards is the the extension base that uses the Swivel Antenna (3G-AE015-R) and the ceiling mount (3G-ANTM1916-CM). Both of these are indoor solutions. The problem is that the building we are trying to deploy the cards in is a steel framed warehouse with a metallic exterior and the signal we get is poor for the 3G and CDMA2000 bands. Is there an outdoor mounting option for these cards? If we penetrate the roof we are able to get good signals on both networks.
For the HWIC-3G-CDMA-V , 3G Wireless WAN HWIC supporting -1xRTT, EVDO Rev A/Rel 0 (Verizon SKU) is supporting and HWIC-3G-CDMA-S , 3G Wireless WAN HWIC supporting -1xRTT, EVDO Rev A/Rel 0 (Sprint SKU) is supporting.
In addition to the Cisco 3G WWAN HWICs, Cisco provides a range of antenna solutions to accommodate a variety of installation environments. Here is the part number and description available.
