What type of Antennas are officially supported by Cisco Context aware service?
A. Cisco does not support non-Cisco antennas for Context-Aware. If you use non-Cisco antennas, heatmaps are not generated, which means that the RSSIs received at these antennas are ignored during location calculation. On the WCS page these are marked as other antennas from the drop-down antenna list for each AP. These are things to remember when you use non-Cisco antennas: • No heatmaps are generated for these APs. • RSSIs received from these APs are ignored. • The antennas gains are allowed to be changed through WLC, which is required for FCC compliance. In order to ensure that APs radiate the correct Effective Isotropic Radiated Power (EIRP), you should use Cisco antennas. If you choose external antenna, and lower antenna gain than actually deployed antennas, then the APs transmit at a higher power level and can cross the FCC specified limits. If you use Cisco antennas, this avoids similar situations because the gains are precisely measured and used internally by the system.
