Saving £50 million NPL helped mobile network operators test the claims made by antenna manufacturers to ensure that the new network to support 3G was made up of antenna with comparable performance data. Background 3G mobile phone technology was a significant step up from earlier systems as it needs to carry large amounts of data quickly so users can view stream video and access the internet from handsets. To support 3G, network operators had to install a new network of antennas, capable of handling higher data volumes and higher network transmission speeds. By moving from older fixed tilt antennas to new electronically variable tilt models, the reliability and access to the network could be improved. However there were many different antennas available and it was difficult to evaluate the
