- Dramatic increases in mobile data traffic are driving the evolution of wireless communications networks.
- Additional spectrum and advances in wireless standards (higher bits/Hz) are necessary and being implemented but are insufficient.
- Large deployments of base stations will also be required to meet capacity requirements over the next 8-10 years.
- Wireless network traffic distributions and constraints on site acquisition make the deployment of macro cells ineffective for the next generation of wireless networks.
- Instead, the majority of network growth will come from the deployment of massive numbers of small, low power cells (pico cells).
- These new architectures will solve capacity problems but bring their own set of challenges.
