I had a customer ask me yesterday if the new MG52 is compatible with the AT&T FirstNet Public Safety network. This gave me the perfect opportunity to test out the MG52 that I got at Cisco Live earlier this month. I popped in the customer's activated FirstNet Sim card and the gateway quickly connected to the cellular network. I entered in their private APN that isolates their network traffic from other customers networks on FirstNet and that worked too. So even though the MG52 is not FirstNet certified, which Cisco is working on, it still works just fine. Here's a couple of pictures of the MG52. This is one of the first ones made and I do not know if the additional MG52 and MG52E will also be green or white in color. I ordered an MG52E yesterday and will report back on what color it is when it arrives next week.
