CW TEC encapsulated – A summary of the inaugural event. By Geoff Varrall, RTT Online



Geoff Varrall, Chair of CW TEC and opening speaker at the event concludes the Cambridge Wireless Engineering and Technology Conference series with a summary of key insights.


CW TEC exposed the fault lines in the mobile broadband industry with Jass Sarai , Technology Industry Leader of PwC, host and lead sponsor, high lighting the low entry costs for new entrants such as Google.  Andy Sutton, Principle Network Architect of EE, pointing out the dependency of OTT value on operator network investment

Graham Peters of Avanti identified the step function reductions in delivery cost required to service developing market low ARPU markets and the role of sparse network satellite systems in delivering next generation 5G access to developing and developed economies.

Sami Susaiho of BskyB exploded the current myths of public Wi Fi and illustrated how existing dynamic frequency selection algorithms limit capacity in 2.4 and 5 GHz networks.

The future of terrestrial broadcasting was explored by Kent Walker of Qualcomm, Alexander Schertz of IRT Germany and Chris Nokes of the BBC pointing out the differences in approach between the US and ROW broadcasting community.

Last but not least IoT connectivity was presented in terms of physical layer requirements (John Haine on narrow band sub channels repurposed from legacy GSM900 MHz channel bandwidth), processor requirements (Paul Morris from CSR on energy budgets) and user device and network economics (Raj Gawera, VP Head, Samsung Solutions Centre).

Our thanks to our generous sponsors PwC, InterDigital Europe Ltd, Microlease and Keysight Technologies, Anritsu and Interlligent, and to an inspiring and thought provoking mix of technical subject specialists who succeeded in generating heated debate in the best CW tradition.
