Want to understand where 5G stands today and what it could be in the future? Light Reading has just the event for you.

The webinar today (July 22) Exploring 5G: Performance Targets, Technologies & Timelines will address the early development of the fifth-generation (5G) wireless technology and what we can expect performance-wise as we move towards expected commercial deployment in 2020. Heavy Reading senior analyst Gabriel Brown will host the webinar along with Dr. Shahram G. Niri, most recently general manager of the 5G Innovation Center (5GIC) at the University of Surrey in the UK.

So, why are major operators and vendors already talking about a technology that is in what Heavy Reading's Brown describes as being in a "pre-standardization" phase. Follow the money, suggests Brown, explaining that vendors are allocating development money for various projects and 5G is amongst them.

"It's because people are trying to secure their R&D budgets now," Brown tells me.

Besides which, there are a lot of moving parts that still need to be nailed down with a wireless standard that is expected to go into initial commercial deployments within six years.

For instance, there is still a debate, Brown says, about whether 5G should deploy a range of well integrated radio interfaces to support various data speeds, applications, and radio frequencies or the industry should push towards an entirely new radio interface for 5G.

Brown and Niri will also discuss the spectrum issues around 5G. The gigabit-and-up download speeds expected to be offered by the 5G update will require swathes of new spectrum. This is expected to drive operators up into the millimeter wave bands to get more bandwidth and demand innovative approaches to eking the most out of low-band spectrum.

So, if you want to be a 5G smartie and impress your friends and family don't forget to register and log on at 12 p.m. EST Tuesday for this webinar.

5G Radio Interface
I think its clear there will be a new radio interface for 5G. The question is will it be single radio interface from sub-1GHz through to 100GHz? Or a variety of interfaces that are then integrated at a system level? And if so, how different will they be?

And what will happen to existing OFDM 4G radio? Is there migration path? Does it evolve? Will there be any backwards compatibility, or not?
