MR76 with MA-ANT-23 in a warehouse

[turek]

Hi, we`re looking to get few MR76 APs for a new warehouse (10m high shelves, creating app 2.5m wide allies, ceiling roughly 12-13m high (considering use of poles for the APs)), with the MA-ANT-23 antennas.

- Does the MR76 have two fixed 2.4GHz and two fixed 5GHz radios, which means, that if client want to use 2.4GHz network only, only two MA-ANT-23 can be used per AP?

- Can I expect the 11db antennas signal to effectively reach >30m down the warehouse alley (there should be no other wireless network in the warehouse)?

Thanks and have a nice day.

The MR76 has 4x antenna connectors. One pair for 2.4GHz and the other pair for 5GHz. One MA-ANT-23 connects to both the 2.4GHz connectors. If you’re not going to use the 5GHz radio then you need to properly cap them and make sure the radio is turned off. Personally I’d set up the 5GHz antenna too, that frequency is less congested and provides better performance, and if you don’t use it now you may in the future (and it’s easier to set it up once rather than revisit APs 10m in the air).

With regards to will the signal reach 30m down an aisle, that depends on how the antenna is positioned relative to the aisle and how it is angled. You can get an idea from the antenna data sheet, https://meraki.cisco.com/lib/pdf/meraki_datasheet_antenna_2GHz_sector_11dBi.pdf, but performing a real world test with an AP and an antenna is the only way to be sure you get the experience you require.
