Celona Tees Up Bigtime on CBRS

Private 5G networking has been discussed a lot over the last year. Engineers and installers are getting trained on design, installation, and support. Though it’s not exactly a new topic, it is still fairly exotic. It’s like we’re all kind of waiting for CBRS to take some big, meaningful step forward that signals “OK, it’s really finally here. Really, like for real.” With Celona’s latest news, that big step has arguably just been taken.

Back in February of this year, I pondered on the past and short future of CBRS in this blog. I’ve gotten to know Celona (the private mobile network company) up close and personal at Mobility Field Day events last year and in 2020 and through a number of private briefings. From where I sit, the entire CBRS and Celona thing has been kind of a slow simmer- waiting for things to break open and get real.

We’re there now.

Platform, Products

Celona is ready to rock and roll the CBRS-hungry enterprise crowd with all the makings of a build-it-yourself 5G networking solution. The details are here, but the short version goes like this- product components of Celona’s integrated solution architecture include:

Celona RAN: Indoor and outdoor CBRS LTE access points built for Enterprise environments. They provide up to 25K indoor sqft and 1M outdoor sqft of coverage. Radio functions are fully automated via Celona software with their power level and frequency channel assignments in the CBRS spectrum, no manual configurations required.

Celona Edge: Private LTE/5G core Enterprise appliance that’s designed to integrate with any existing network environment. Deployable on-premises for strict SLA enforcement for local applications, within private / public / edge clouds for service scalability, or both.

Celona Orchestrator: The AIOps platform that enables remote installation of Celona’s access points and Edge software, across multiple enterprise sites. Orchestrator provisions Celona SIM cards against required device level access control policies within the enterprise network. Providing more than monitoring of infrastructure components, Orchestrator also keeps track of application and device KPIs for Celona MicroSlicing™ (think QoS on steroids, but there’s more to it than just that).

Everything you need to build your own private 5G environment.

Aruba Networks Partnership

Celona has also formed a partnership with Aruba networks, who will sell Celona gear where a given customer is looking for not just Wi-Fi but also private mobile networking. Given Aruba’s lofty position in the WLAN space, this is a good thing for Celona as they set out to conquer this new market.

A Fat Wad of Series B Funding Never Hurts

Not that further validation that Celona is doing things right is needed, but one could argue that the cash the company has just secured is another indicator that industry is taking both Celona and their new tech solution seriously.

There are some decent folks at Celona that I’ve known in different roles at other companies, and it’s exciting to see them move their collective vision forward. I’m looking forward to seeing how this unfolds for Celona, the fledging CBRS industry, and for the customers about to go down this road.

See the new Celona Platform.

It’s Time for YOU to Get Wise About CBRS

CBRS search

It stands for Citizens Broadband Radio Service, and has nothing to do with CB radio despite the similarities in the acronym. It’s time for my fellow Wi-Fi types to start paying attention to CBRS for real, and I’ll explain why in a bit.

A Quick Look Back to 2105

The CBRS thing been simmering for at least a half-dozen years. Let me quickly take you back to 2015, where I sat in on a related session at Wireless Network Field Day 8, by Dave Wright. Back then, Dave worked for Ruckus Wireless, now he’s the Director of Regulatory Affairs & Network Standards at CommScope, and President of the CBRS Alliance. Dave’s a fantastic gent, if you ever get the chance to talk with him. But even though that 2015 presentation could not have been delivered by anyone better, it still felt kinda faraway and foreign to the ears of a room full of Wi-Fi folks.

Almost There- 2019

But 2015 gave way to the future, and Dave’s vision very much would come to fruition. Sticking with Field Day, I was fortunate enough to go to Mobility Field Day 4 in 2019. This time the presenting vendor on the topic was startup Celona (new company, but staffed with some deep wireless experience and familiar names to us in the WLAN industry). At the time Celona presented, CBRS had long since advanced from being a twinkle in the eye of folks like Dave Wright, but still wasn’t quite ready for market as a production option for Private LTE and other applications. (What other applications? There’s a good paragraph on that in this Network World article.)

Early 2020- The FCC Opens the Floodgates for CBRS

Just a few weeks ago (it’s mid-February as I write this), the FCC delivered the news that everyone with a stake in CBRS, Private LTE, and in-building cellular was waiting for: the 3.5 GHz spectrum was officially available for sharing for these applications. Here’s a good article on that, along with the FCC’s own reference pages on 3.5 GHz.

Now things are moving… and we get to why we as Wi-Fi folks need to start paying attention.

Our Turf is Soon to Be Trampled On

I find the marketing blather that has 5G making Wi-Fi extinct, or that has Wi-Fi 6 making cellular irrelevant, to be pretty asinine. But then again…marketers. Whatever. It’s pretty clear that several trains have left the station, and they all will impact our environments and possibly/hopefully our employment, skills, and project opportunities.

Wi-Fi 6 is a given- it’s what comes next for us WLAN doers. 5G has new relevance given that a small cell will need to bolted up to every street light, cactus, bus stop and homeless person to get the coverage and performance that the mobile industry is promising out of Millimeter-wave 5G systems. Bringing 5G (or even 4G) inside of modern RF-unfriendly buildings gets us back to discussions of CBRS and private LTE. And so does the notion of industrial settings where maybe LTE-style wireless makes more sense than Wi-Fi for wireless connectivity, for a number of reasons.

We need to not only understand the changing wireless landscape, but also to embrace it and try to stake our claims in it.

Get Educated

There are no shortage of general-information articles out there for CBRS, private-LTE, etc. here’s a great one from Corning (I just spoke with them on this topic, but that will be it’s own blog). And there is certainly a lot of marketing floofypoo to be stepped around.

But if you want more formalized learning, check out this offering from CommScope. I have not taken it yet, but have heard good things from esteemed colleagues who have. Coursera also has a CBRS offering, and I have every reason to believe that CBRS will eventually manifest itself through CWNP’s excellent training materials in some form or fashion.

So… why care about CBRS? It’s here, for real, for starters. It’s being deployed. Someone needs to design it’s coverage, and tools like iBwave are already being used by many of us to do Wi-Fi. Why not get a piece of the new pie? If we don’t, someone else will. People are gonna luuuuuuv their Wi-Fi 6, yet are still going to demand rock-sold in-building cellular after spending fat coin on those $1K+ mobile devices and as more devices become “wireless” in every possible definition of the word.

This is the new world, my friends. Digital transformation, blah blah blah. There’s no escaping it.
