Telefonica's LTE Nano Small Cell

The popularity of drones and balloons have made it possible to try and come up with innovative solutions for providing connectivity, surveillance and many other use cases. I have talked in detail about the UK operator EE's attempt to use Airmasts (which are now called E.M.M.A. - Emergency Mobile Mast Aid) and connect rural Scotland using Drones and Helikites.


In my Small Cells at MWC report, I talked about how there were many operators, vendors, etc. showing different things they were doing with drones and recently in my posts talked about Verizon's 'flying cell-site' and AT&T's 'Flying COWs'.

I only looked briefly at Telefonica's announcement about the LTE Nano.

From the press release:

This innovation, an evolution of the former project “LTE in a Box” presented at the MWC2015 that brought all the benefits of private critical LTE communications to the corporate world, will allow to bring the same advantages to new scenarios where small scale, low consumption and portability are paramount.  LTE Nano runs on a 40 grams SBC (Single Board Computer), on a Quad Core Cortex™-A53 processor and 2GB of RAM.

For the LTE Nano Project, Telefónica has integrated several components, one of the most essential being the EdgeCentrix virtual Enhanced Packet Core (vEPC) solution from Quortus, one of the most efficient and scalable software implementations of a mobile network functionality, able to run the essential elements of both 4G and 3G networks, including voice and data communications, with minimum HW requirements.

The most eye catching use of LTE Nano is for the rescue teams. An autonomous and portable LTE solution in a backpack, providing critical LTE communications in isolated places with no pre-existing coverage and difficult Access.

In addition, LTE Nano could be used to access retail intranets, though apps could do this job much better I think and
private LTE communications for small offices. Here I remain to be convinced that this scenario will not be superseded by WiFi calling, etc.

All these scenarios include the well-known Quality of Service provided by LTE networks in licensed spectrum which guarantee the absence of interferences and the security of communications, typical characteristics of regulated environments.

The presentation on LTE Nano is available here and a video from MWC is below (in Spanish):
