We saw Raspberry pie hotspots before but this one, created by Reddit user Treasure Hunter613, has a few extra features that really add to the on-the-go experience. This Pi-powered LTE WiFi access point doubles as a NAS and comes with all the support that the Raspberry Pi provides.

According to Treasurehunter613, the module consumes very little power, which makes it ideal for travel. Expanding NAS storage capacity is as easy as connecting a second drive. The NAS aspect of the build is via Samba a free software reimplementation of the SMB networking protocol. Samba is very popular with creators of Raspberry Pi network storage projects.

The project doesn’t even require the latest Pi, relying on a Raspberry Pi 3B+. While still a formidable Raspberry Pi, the Raspberry Pi 4 has the power and support for Gigabit Ethernet. For LTE support, it has a Waveshare 3G/4G/LTE HAT as well as two Proxicast 3G/4G/LTE antennas. To keep things compact, a SanDisk Extreme Pro 1TB SSD flash drive is used for NAS storage space while the battery makes the whole operation mobile.

Treasurehunter613 has documented the parts and setup steps needed for anyone to recreate the project. The steps include setting up Wi-Fi hotspots and setting up the 4G HAT.

Although there are already many modules offering mobile WiFi support, the advantage here is in the versatility of the Pi. Attaching a larger MIMO antenna or larger drive for the NAS is always an option. It also adds functionality that can be shared with multiple users who can access media hosted on the NAS using their mobile devices locally.
