We are going to be replacing out existing wireless infrastructure at one of out sites. Currently this site has 6 Cisco AIR-Cap1532e 5 of them have 5ghz Directional antennas and there is one (on the main building) with dual omni antennas.
We are thinking about replacing them with MR74 and I am looking at the best suggestion for antenna choices or suggestions on different AP if need be.
MR74 requires two antennas, one for 2.4GHz and one for 5GHz. Unless you buy a 3rd party antenna that is dual-band already with 4 connectors, then you don't have to worry about it. However support won't help you if you have issues unless you use a Meraki antenna.
