Verizon Boards the NB-IoT Train

Verizon says it has completed its first NB-IoT data session test and plans to deploy the Internet of Things-focused cellular specification across its LTE network in 2018.

Verizon Communications Inc. (NYSE: VZ) said Thursday that it used Ericsson AB (Nasdaq: ERIC) software to test the narrowband cellular tech in 180KHz of spectrum. Unlike consumer LTE, NB-IoT offers an efficient option for hooking up smart sensors and other machine-to-machine applications because it uses very little power for its 200 Kbit/s connections and very little spectrum, which gives devices a battery life that can be measured in years.

T-Mobile was the first carrier to offer commercial NB-IoT services in the US: It launched in Las Vegas in October 2017. (See T-Mobile Rolls Out $6-a-Year NB-IoT Plan.

Like T-Mobile, Verizon likes NB-IoT because it can be deployed in LTE spectrum "guard bands" that sit between LTE channels to prevent interference. Thus the dedicated 180KHz bandwidth for NB-IoT "does not share spectrum resources with commercial smartphone traffic," Verizon noted in a statement.

Huh? Are you referring to me? Because I've never "written off" NB-IoT as you suggest and, to date at least, you haven't commented on the stories I've written about AT&T and Cat M. See: http://www.lightreading.com/iot/nb-iot/us-carriers-place-bets-on-cat-m-and-nb-iot/a/d-id/736648http://www.lightreading.com/iot/nb-iot/us-carriers-place-bets-on-cat-m-and-nb-iot/a/d-id/736648 So I'm not sure what this is in reference to?

Humble pie? It must be getting difficult now for these so called "experts" who only 6 months ago were writing off NB-IOT. I constantly challenged their articles, because they were so full of mis-information. Now NB-IOT is everywhere, is growing rapidly and will dominate the IoT landscape. Anyone looking objectivly at all competiting technologies could see this was a no-brainer. Infrastructure already in place, open standards based eco-system open to all device vendors etc.

Commercial networks and prices are already avaiable, and the technology not only works great, but is being constantly improved by companies with billions of dollars invested in making this work.

So whilst I like reading some of these articles, I take a lot of them with a grain of salt.

Of course AT&T will fall into line. IoT cameras are a great idea, but hardly a battery powered, mass deployment opportunity. You can do great remote camera stuff now over 4G. They will soon be with the likes of Orange, trying to shoe-horn LTE-M into applications where NB-IOT makes mcuh more sense, at the expense of customers and device vendors. Having thoroughly tested both technologies, NB-IOT is the only way to go for battery powered sensors with long asset lives.


I look forward to the next article telling us how AT&T are now doing an NBIOT nation-wide rollout.
