5G Moves into the light: Holographic massive MIMO

CTN Issue: June 2016

This month we highlight new technology that uses optical holographic methods to literally image the signals coming off the massive MIMO antenna array, avoiding a lot of the difficult issues with ADC cost and beam processing. Could this be the missing technology to bring practical mMIMO to the field? We thought it was fascinating. Your comments are most welcome.

I've got you under my skin, no really: the technologies that will drive 5G and beyond

CTN Issue: May 2016

In this edition we wanted to take a little step out of the world of 5G and air interfaces and take a look at the technology that will, at the end of the day, give us a reason to want all of this new wireless capability. Ajith Amerasekera from the Berkeley Wireless Research Lab has kindly put together a selection of technologies that they are developing that he believes will be critical to the use of 5G and maybe beyond, including some that you may need a little outpatient surgery to take advantage of. I'm sure there are many other ideas in labs out there so comments and suggestions are welcome, as usual.

Neutral Hosting: A piece of the 5G puzzle?

CTN Issue: April 2016

Neutral Hosting is an idea that has been kicking around for quite a while now. This month we take a brief look to see if its time has come. Here, by Neutral Hosting we mean the operator essentially rents the equipment running the Radio Access Network (RAN) from a neutral third party who "hosts" the software/algorithms the operator wants to run. The radio access is then hooked back into multiple operator networks to allow the operators to complete the network portion of the system. So why would anyone do this?

5G: Down the Rabbit Hole

CTN Issue: March 2016

Fresh from Mobile World Congress, my favourite "tell it like it is" curmudgeon-cum-analyst Richard Kramer has kindly agreed to share his thoughts on the state of the industry and on 5G in particular. While reading his article, I had two thoughts that align with his position: 1) How long will it take to really do VoLTE well? and 2) 3G's lifespan was quite short and we should probably expect a lot more runway for 4G. Anyway, form your own opinions and send them to our comments page!
