Super Bowl of Wireless: Phones at Microwave

Super Bowl of Wireless: Phones at Microwave

Super-Bowl-2-of-Wireless-Phones-vs-Aviat-Microwave-Radios-February-5-2016Here at Aviat Networks we have the privilege of extremely close proximity to the site of Super Bowl 50, at Levi’s Stadium in Santa Clara, California. We are about a half mile away and from our building parking lot we can clearly see the venue where the Carolina Panthers and Denver Broncos will clash for the championship of American professional football.

And while hundreds of millions of Americans and hundreds of millions more people around the world will watch the game raptly on television, 75,000-plus fans at the ballpark will see it in person. Not only will they watch it with their own eyes but also use their iPhones, iPads and Android smart devices to tweet, post YouTube and Vine videos or otherwise cheer or jeer the real-time action of the game on Facebook.

What many don’t know concerns the game within the game: how all this wireless data will get out of the stadium to the mobile service provider networks and finally onto the Internet and social media. As it turns out, Aviat Networks will also have an up-close virtual seat to this tilt of the cellular subscribers vs. their wireless carriers.

Layer 3 intelligence: cell sites need more than dumb pipes

Once upon a time, cell sites served as little more than passive pass-throughs for phone calls and text messages. Because voice calls and SMS posts did not require much wireless capacity cell sites did not require very robust provisioning. Now that the Internet has gone fully mobile with streaming videos and real-time applications such as VoLTE and IPTV regularly crushing network capacity design parameters, the time to get smart about backhaul and access traffic has arrived. The time for Layer 3 intelligence is now.

In fact, for some time mobile cell sites have transitioned from simple Layer 2 connected sites for 1990s-style mobile phone and data access to multipurpose centers for delivering new, smart device services. However, they can only provide new, smart services if they are built upon Layer 3 technology that offers intelligent handling of wireless traffic. Only IP routing technology is capable of such functionality.

But here comes the catch regarding IP routers providing Layer 3 intelligence at the cell site. With more than 50 percent of the wireless traffic in the world going to and coming from mobile sites through backhaul radio, Layer 3 intelligence must have awareness of microwave networking. And regular routers just do not offer microwave awareness. A new class of device must fill the void left by regular routers that frankly do not have enough “smarts” to deliver Layer 3 intelligence for cell sites that depend on microwave backhaul. A device that combines the best attributes of microwave radios and IP routers.

To provide a closer examination of this issue, Aviat Networks has authored a new white paper—no registration required—that makes the case for Layer 3 intelligence at the cell site. And how to implement a new class of “smart” devices that enable microwave radio awareness with IP routing.
