Joe Hoffman, Practice Director ABI Research, recently visited the Nokia Networks Solution Experience Center at our facilities in Karaportti, Finland, and declared “Everything is awesome . . . when you have Centralized RAN!” Joe gives a nod to The LEGO Movie as a metaphor to share the improvements he saw in our C-RAN solution:
Being an industry analyst is like going to theater all the time: one occasionally sees “awesome things!” But just as in the theater, you are only a spectator and not part of the cast, just watching and never doing. So it was at the Nokia Networks Solution Experience Center where I was treated to a demo of Nokia Centralized RAN (C-RAN) and observed what the intelligence of a Smart Network can do when put to work solving a difficult problem. In this case, its C-RAN product roughly tripled performance and capacity in a live on-the-air demonstration that approximated a congested venue (such as a stadium event). Seeing this, the marketer in me sprang into action and noted “Everything is awesome!”
Centralized RAN is a special solution for situations with ultra-high subscriber density and uplink congestion. You can think of venues such as stadiums, concert halls, train stations, outdoor areas, or any situation where many people are getting together to share information as the key areas which benefit from C-RAN. In these locations, the traffic is “uplink heavy” as users upload pictures, videos, Instragram updates, Facebook updates, WhatsApp messages – really any content as they enjoy and share what they are experiencing. With many people uploading all of this data, the devices are creating enormous level of interference with each other, trying to shout to the base stations and compete for their attention. As a result, network capacity effectively shrinks because the capacity is impacted by the interference. Nokia Networks’ unique and patented innovation Centralized RAN has several sophisticated algorithms for reducing the interference in such environments.
ABI’s Joe Hoffman sees the benefits of Centralized RAN as the start of the many innovations that LTE will bring operators:
Innovations such as Nokia Centralized RAN are in production and reflect the early days of LTE innovation, so there is likely much more innovation to come. I can only hope to see this repeated with the iPhone 6 Plus, VoLTE, Wi-Fi, and VoWi-Fi in the mix. When that happens, we will know that “Everything is uber-awesome!”
