Schoolar: MWC 2015 RAN review – 5G, 4.5G, and some other random observations

As expected and even discussed here on FierceWireless prior to Mobile World Congress, the annual mobile confab was ripe with 5G talk. Just about every major RAN vendor, with the exception of Alcatel-Lucent, had something labeled in its booth as 5G. This doesn't mean Alcatel-Lucent didn't have plenty to say on the subject during MWC.

Schoolar: LTE could be just what 450 MHz needs

450 MHz has been something of a white elephant in the wireless community. Its propagation ability makes it a valuable commodity for trying to cover large, lightly populated areas. At the same time the limited spectrum availability in this band hinders performance, and revenue potential of building devices or deploying services at this band have so far limited the development of an ecosystem. Sure there are CDMA deployments in that band, but they haven't really make 450 MHz a hot market. Ovum estimates CDMA450 users represent well under 10% of the tal CDMA user base. However, LTE450 (LTE at 450 MHz) might finally change all of that.

Schoolar: 5G – how much longer until we get there?

What is 5G? When will we get to 5G? What will happen to 4G when we get to 5G?  All of those 5G questions are interesting, but ultimately none of them currently have a satisfactory answer and it will take time before those answers become known.

Schoolar: Multi-mode LTE getting a fresh look from operators

Looking back at the "What to expect from MWC 2014" column I wrote in early February, I would say the conference met my expectations. I want to say I'm the world's greatest prognosticator but that would be a lie. Surprises are rare with wireless infrastructure. Vendors often give me a heads up on what to expect and having watched this market for some time, I can tell you that if one or two vendors are doing something, you can be sure their competitors are working on something similar. But, that isn't to say I didn't encounter a surprise this past February while in Barcelona.

Schoolar: From top to bottom, it isn't easy being in the base station business

Having spent the last several months updating Ovum's RAN forecasts and market share estimates, one thing is very clear: the base station business is a very tough business to be in no matter where each vendor falls within the market share ranking.

Schoolar: 4 vendors to watch in optimization

Daryl Schoolar ovum

As you can imagine, as an analyst, I get the opportunity to talk with many of the companies in the optimization space. Some are well known, while others are just pulling the curtain back on their operations. Here are four start-up specialist vendors I have talked with recently that I think others should know about as well.

Schoolar: The song mainly remains the same for wireless infrastructure in 2013

Now that the Mayan apocalypse has passed without event, and we are all still here, there is no avoiding 2013. For an analyst like me, the start of a new year is a time to take stock of the previous year and to think about what the new one will bring.
