From: Bob on 12 Mar 2010 05:02 OFCOM has produced a couple of studies this year which may be of interest to some:- 1." With consumer demand for high-quality, multimedia-rich services expected to increase in the next decade, network operators are starting to deploy new access networks with fibre all the way to customer premises in order to dramatically increase the bandwidth they can provide. It is often thought that these fibre networks offer infinite capacity; however, in reality, the practicalities of deployment, architectural choices and performance constraints of networking equipment will lead to capacity being limited." <http://www.ofcom.org.uk/research/technology/research/emer_tech/fibre/fibre.pdf> 2.They have focussed on STB's and cellphones but may still be of interest.I don't know why they have done it as 2 separate documents as they are very similar. "This study examines issues involved in improving the performance of radio receivers in consumer equipment such as TVs and cellular devices. The study focuses on the cost / performance trade-off to make a receiver less susceptible to interference from other frequency bands, based on technologies that can be envisaged over the next ten to twenty years." <http://www.ofcom.org.uk/research/technology/research/speclib/receiver/receiver.pdf> <http://www.ofcom.org.uk/research/technology/research/speclib/receiver/appendices.pdf> |
