Locations: A geolocation list is required. This allows a device to specify its current location plus additional anticipated locations when allowed by the regulatory domain. At least one location must be included. Geolocation must be given as the location of the radiation center of the device's antenna. If a location specifies a region, rather than a point, the database may return an UNIMPLEMENTED error if it does not support query by region.
There is no upper limit on the number of locations included in a available spectrum batch request, but the database may restrict the number of locations it supports by returning a response with fewer locations than specified in the batch request. Note that geolocations must be those of the master device (a device with geolocation capability that makes an available spectrum batch request), whether the master device is making the request on its own behalf or on behalf of a slave device (one without geolocation capability).
