C-RAN Is About to Get More Serious, but No, the RAN Will Never Disappear into the Cloud

Summary Bullets:

  • C-RAN’s adoption is likely to grow significantly soon, thanks in part to evolutions in the underlying technologies.
  • Long term, future RANs will see a dynamic mix of centralized and distributed functions.

In 2016, we’re likely to hear even more about C-RAN than we already have. It’s not a new concept, and plenty of operators have deployed mobile access network architectures in which the baseband processing units are centralized, stacked or pooled, linked to remote radio units elsewhere. As portions of the network become increasingly virtualized, baseband processing will become virtualized, too – thus, centralized RAN will evolve into cloud RAN. This won’t happen everywhere, of course, but its use is likely to spread thanks in part to some significant advancements in C-RAN technology coming soon.

LTE TDD: Driving the Universal Nature of LTE – Whether That’s Understood or Not

If I can believe my desk calendar, it’s almost summer. With the longest day of the year fast approaching, my mind has turned to all of the usual topics: fireworks, hot dogs, bitter jealousy aimed at European colleagues who take four-week vacations, LTE TDD.

Okay, summertime and LTE TDD might not go hand-in-hand, but there are some real reasons the TDD implementation of everyone’s favorite 4G technology has been on my mind. Earlier this month, I spent some time with my consumer analysts out in Kansas City visiting Sprint; with LTE TDD at the foundation of Sprint Spark, you know the technology was a major component of the discussions with them. This week, I’m sending some of my team to Shanghai in order to catch up with our friends at ZTE. Along with Huawei (which we visited in April), ZTE is expected to benefit significantly from LTE TDD deployments in China over the next year or so; the two vendors won the lion’s share of China Mobile’s LTE TDD awards. This was long-expected and the scale won in supplying these networks is expected to benefit them, particularly if the other Chinese mobile operators follow suit.

You can see why I’ve been thinking about the technology, right? Great. Then let me throw in another wrinkle. Continue reading “LTE TDD: Driving the Universal Nature of LTE – Whether That’s Understood or Not”
