Around 80 percent of our time is spent indoors with approximately 90 percent of our information exchanges being generated whilst in the home or office. However, the poorest cellular access is probably experienced within buildings. If high-speed data services are to provide the next revenue boost, then femtocells (or something similar) will have to be deployed. These units have the added benefits of offloading traffic from the cellular backhaul and delaying the need for more 3G base stations.
