Customer needs both wireless location services and also wireless voice. My thought is to use 802.11a for voice with the 7921G and 802.11b for location services. Since location services requires the highest AP density, it would seem that an 802.11b survey for location services would result in the resulting AP grid likely being able to support voice at 802.11a. Has anyone had experience with this? What are some suggestions for spectrum use and for performing a survey when both wireless voice and wireless location services are required?
