Posts about Radio Access Networks

In an ideal world, installing a new radio base station (RBS) is simple. You power it up, connect it through a backhaul network to the mobile core, and you’re done. You’ve increased both the coverage and capacity of your mobile network. But in the real world things tend to go a little differently. When you install the RBS, you discover there’s no backhaul connectivity provisioned yet. Another site visit and several days later, and you’ve hopefully managed to connect your base station to the mobile core. It’s at that point that you find out that, for some unknown reason, they won’t talk to each other. Okay, your team will get this sorted on their next site visit. This finally gets it operational but, over the next few days, you discover performance is not as expected. This is a tricky one and it takes some time before the field services team eventually recognizes that there’s an issue with network synchronization. And I’m sure you’ll hear stories from field service guys with even more complications, additional levels of problems and all the related cost. Think about the waste and frustration it creates ...

Mobile operators are facing two important decisions when planning their small cell rollout in public areas. The first question to be answered is how to transport traffic from small cells to the edge of the mobile core, while the second question concerns interference management. Although these are two distinct decisions, they are closely related. The performance and functional capabilities of the network connecting small cells determines which solutions the mobile operator can use to mitigate interference. Vice versa, the choice of interference management tools drives the operator toward specific connectivity solutions.

LTE-Advanced Release 10 is a major enhancement of the Long Term Evolution (LTE) standard developed by the 3rd Generation Partnership Project (3GPP). This new technology is targeting peak data rates up to 1Gbps and introduces new concepts with the ultimate goal of designing a system that is drastically enhanced in both cell capacity and coverage.
