Does the Short Road to 4.5G Mean a Long Road to 5G?!

4.5G vs. 5GBrowse through industry literature or conference proceedings and trade shows, and you’ll be inundated with talk about 5G. On the other hand little is to be found on “4.5G”, or technically speaking, LTE Release 12 and 13 branded as LTE-Advanced Pro [which incidentally I find to be a bad choice of terms that I prefer to use 4.5G even as I don’t like the nomenclature!]. Why is there little to discuss on 4.5 G and much to talk about on 5G? What does this tells us about 4.5G and 5G? And, is there something between the lines that we can read? Read more of this post

The State of IoT Connectivity

IoT: LPWA vs. NB-IoT LTEMWC16 was a great venue to check the pulse of developments in IoT connectivity. We summarized part of our observations which we shared and published (link). It caused many follow ups by colleagues and friends who voiced a wide range of opinions that I thought some further color would be useful.

To start, the main challenge in IoT is applications. The challenge is not technology which exists. Rather, the issue is in making the business case for IoT to arrive at a functional solution. That cycle is long and expensive. When we drill deeper into many IoT activities, the question becomes “who will pay for this service.” Technology can lower the cost, but there are many elements that are not technology related which gate the process.

Which IoT Technologies Will Die Out?

LPWA LTEIoT use case are fragmented with different requirements. To match these requirements, a number of IoT connectivity solutions are available including wide-area low-power (LPWA), cellular wireless technologies (EGPRS, UMTS, LTE of different varieties), and short range technologies adapted to cover wide areas through mesh networking (ZigBee, WirelessHART, etc.) or extension of point-to-multipoint technologies (e.g. 802.11ah/HaLow). Each of these technology spaces is crowded with options, so which will survive and which will die out? Read more of this post
