Verizon Issues First 5G Radio Spec

Verizon said Monday that it has finished its initial 5G radio specification -- pushing ahead of the industry-wide standardization process -- before it launches a fixed wireless broadband pilot in the US in 2017.

Verizon Communications Inc. (NYSE: VZ) formed its 5G Technology Forum (V5GTF) late in 2015 with Cisco Systems Inc. (Nasdaq: CSCO), Ericsson AB (Nasdaq: ERIC), Intel Corp. (Nasdaq: INTC), LG Electronics Inc. (London: LGLD; Korea: 6657.KS) , Nokia Corp. (NYSE: NOK), Qualcomm Inc. (Nasdaq: QCOM) and Samsung Corp. The operator says the group "has created a common and extendable platform for Verizon's 28/39 GHz fixed wireless access trials and deployments." (See Verizon & Partners to Field Test 5G in 2016.)

Verizon is expecting to launch a 5G fixed wireless trial in 2017. It has been testing a 28GHz pre-5G specification with Samsung in multiple locations in New Jersey, Massachusetts and Texas this year. (See Verizon Will Pilot 5G Fixed Wireless in 2017.)

"End users will experience gigabits-per-second throughputs and single-millisecond latencies," Verizon says in its 5G radio page.

The "5G" radio interface comprises the interface between the User Equipment (UE) -- i.e. handsets and smartphones -- and the network. The radio interface covers Layers 1, 2 and 3. (See Is This the 5G You're Looking For?)

Verizon's radio interface will use Orthogonal Frequency Division Multiplexing (OFDM) with a cyclic prefix (CP) to buffer the signal from the interference in the downlink and uplink. (See 5G Needs More Joined-Up Thinking – Heavy Reading.)

Verizon is getting its radio specification out way ahead of the official first 3GPP 5G radio specification. The New Radio (NR) requirements are supposed to be agreed by September 2016, with Layer 1 and 2 work slated to be completed by 2017. The first 3GPP 5G radio is due to be "baked" by June 2018.

"They created a platform for Verizon's 28/39 GHz fixed wireless access trials, which have been ongoing since last fall. Because they're oriented towards current trials, the standards could be revised before 5G goes live for consumers, something Verizon says it intends to accomplish as early as next year."

OFDM may work for fixed mmwave 5G, but it definitely doesn't work as well for mobile mmwave 5G.

"I think OFDM will be there for lower bands but at higher bands I am not certain and my personal thinking is probably I will not use OFDM, I will use pencil beams which will be non-OFDM. But in reality in lower bands I will probably use OFDM." - Hossein Moiin, Nokia CTO

Kickstarting 5G?
Verizon says that releasing this spec will help vendors develop products. Seems like they are betting on the eventual 5G radio interface being OFDM-based.
