Gigabit LTE is becoming a reality today and being strongly hyped at the moment, combining several techniques and frequency bands to achieve headline peak data rates. We review the different alternatives and consider if this is a threat to 5G.
There is a huge range of free OpenSource software and hardware designs for many applications. We looked at whether there’s enough available to build your own LTE small cell and found it wanting. At the moment, you’d be better off buying a professional product unless for lab and experimental purposes. Meanwhile several well-funded projects with substantial support from Facebook and several large operators are planning to change that, ultimately aiming for commercial deployment within major mobile networks.
Ericsson’s Radio Dot has been the company’s primary medium-sized in-building solution for some years, competing with Enterprise Small Cells and DAS systems. Last week saw four significant additional features being announced, which some would see as catching up with Huawei’s Lampsite 3.0 launch announced some months ago.
For me, CBRS was undoubtedly the key topic of the MWC Americas event. This lightly regulated 3.5GHz spectrum band using standard TD-LTE cellular service is unique to the US, and will open up a variety of new business models.
A half day seminar by the CBRS Alliance featured several strong supporters and painted a picture of how it will become available and who will use it first.
Three milestones are required before commercial services can commence:
Two technologies you are going to hear a lot about this month are CBRS and LAA, sometimes branded as Gigabit LTE. A recent announcement showcased Gigabit speeds purely on CBRS alone. For the medium term, we consider what the potential to combine licenced, CBRS and LAA spectrum are likely to be.
