First Hacks: The Brand New Nokia 5G Gateway Router

Aside from being the focus of a series of bizarre conspiracy theories, 5G cellular networks offer the promise of ultra-fast Internet access anywhere within their range. To that end there are a new breed of devices designed to provide home broadband using 5G as a backhaul.

Via ADB a shell could be opened on Android, but on further  investigation it was found that the Fastmile is not a single device but two separate ones. Inside is a PCB with an Android 5G phone to handle the connection, and another with a completely separate home router.


With access to the Android side and a login prompt on the router side that was as far as he was prepared to go without risking bricking his Fastmile. It only remained to do a teardown, which reveals the separate PCBs with their own heatsinks, and an impressive antenna array. Perhaps these devices will in time become as ubiquitous as old routers, and we’ll see them fully laid bare.


It’s a shame that we’ve had to write more about the conspiracy theories surrounding 5G than real 5G devices, bu ..
