Multipoint Microwave for O2 4G trial
Cambridge Broadband Networks and its VectaStar multipoint microwave hardware is to be used in the recently announced O2 4G mobile broadband trial in London. The 2.6 GHz band used by the trial 4G service, will have most of its tower sites backhauling using a 26 GHz microwave link.
The advantage of this way of getting data from a cell tower back to the core network is that it allows for more rapid deployment, and by aggregating capacity at a central point, will allow for efficiency cost savings, namely that a 10 Gig connection is a lot cheaper than 10 x 1 Gig links in separate locations.
For the use of 4G in increasing broadband coverage into parts of the UK where landline broadband fails to meet current expectations, the ability to send data from outlying cell towers to towns with existing and cheaper fibre backhaul provision will be important in delivering the fastest speed possible for every pound spent.
