I’ve recently deployed 3 900MHz AP’s on top of a water tower with sector antennas. the tower is domed so I had to place the AP’s in the middle with only about 45" of spacing between them. Has anyone had problems with radios being too close to each other?
As long as the APs are synchronized with a CMM, they can be as close together as you can mount them. If you’re trying to get by without synchronization, then you either need shielding or significant separation (100 feet) or both (a building in between). Motorola recommends synchronization for APs and BHs in the same band that are closer together than 4 miles.
thanks, that helps me immensly
