Streaming video, gaming, advanced applications, and more are putting demands on today’s wireless networks and increasing the need for capacity and tower density. In response, carriers are looking at options, such as Wi-Fi underlay and backhaul, to limit the load on networks.
Simultaneously, various carriers are conducting trials and looking to introduce LTE-Advanced to the masses in 2013, which promises to make a performance leap by bringing more low-powered nodes closer to the user. However, issues around standards and how each carrier will make network handovers complicate things when deploying heterogeneous network components such, as smaller cell sites (e.g., picocells, femtocells, etc.).
