We are excited to announce that we have launched our new Hive Community! HiveNation will remain as an archive, but all new posts, discussions, and articles will be created on Hive Community. You can visit our new community at thehivecommunity.aerohive.com
The individual advertisements themselves are not very energy intensive, so your battery-powered beacon will likely perform consistently until the point that you no longer have enough energy potential in the battery to advertise at all. And then -- ack! -- it's dead.
One of the reasons our RadBeacon USBs have been so popular is that they can be plugged into any USB power source -- a standard USB power supply, an Aerohive AP with an available USB port, an existing POS system, etc. -- and the need to be concerned and to maintain batteries goes away entirely.
