We strongly believe that today’s wireless networks will not be able to cope with the coming bandwidth explosion that will result from increase use of mobile data and video applications. In our opinion, there are several areas of the network that will have to be upgraded (and possibly augmented by usage restrictions) if mobile data grows anywhere near what Cisco predicts for the ‘Zettabyte Era’ :
1. Access networks will have to be re-organized to use pico cells, Distributed Antenna Sysems (DAS), or equivalent user segmentation scheme for efficient spectrum re-use within a given metro area.
2. Many networks will still be congested during periods of heavy video and multi-media downloads/ uploads or streaming. In that case, the operator will have to meter service or even restrict/ block certain apps, e.g. AT&T blocks Sling Box video to handsets.
3. The other choice is to upgrade the mobile access network to an OFDM/OFDMA wireless access technology like WiMAX or LTE. . Those networks use spectrum more efficiently and have enhancements like MIMO that further contribute to better utilization.
Problem with this is that it takes a lot of capital to build out a new infrastructure. Further, mobile LTE is a lot farther from being commercially realized then most people expect. That leaves mobile WiMAX as a viable option, but………..???????
4. Both local and metro backhaul segments will need to be upgraded. The current average cell backhaul is equivalent to only 5 x T1′s and it must be increased in accordance with the volume and bandwidth of traffic in the access network. Microwave backhaul is the solution for local backhaul and will compete with fiber (where available) for metro and longer distance backhaul.
