Next Gen 450SM.. With GPS perhaps?

Include a GPS chip in future PMP450 SM's for ability to auto map subscribers, seriously how isn't this a  thing yet could be a budget oem gps chip just enough for mapping subscrbers and removing a good deal of overhead, the cost of gps chipsets have gone through the floor lately, so i'm 99% sure in this modern age you can squeeze in a nice feature like this so your next gen wireless manager can FINALLY automap cpe's and ap's to locations.
