The entire wireless industry is on the cusp of a transitive time where Layer 3 IP services will be needed in the access portion of the network. And the backhaul will be needed to provide them.
Under the pain of restating the obvious, we have all seen the explosive growth of smartphones, tablet computers and other radio-frequency-loving gadgets like e-readers. All these new-fangled high-tech contraptions need Layer 3 IP/MPLS services in the access and backhaul in order to deliver a satisfying, seamless user experience—especially for enterprise services. The question is how will the mobile network operators (MNOs) be able to deliver these services from their thousands or tens of thousands of cell sites?
Typically, the answer would involve deploying a regular router for IP services at each and every cell site. But have you seen the prices of routers lately? Cisco didn’t get to where it is today without having some heavy pricetags attached to all the heavy iron it’s shipped over the last 20-odd years. Suffice to say, it would be a pretty penny if MNOs equipped all their cell sites with their own dedicated routers. So what else can be done, you query?
It just so happens that Aviat Networks’ director of corporate marketing, Gary Croke, has posted an article at RCR Wireless going over what to do in these types of situations. But we’ll give you a hint: the IP router function should be folded into a single multi-service, multi-layer cell site device. Read the rest and let us know what you think.
