The World’s Most Cost-Effective Multi-Beam Phased Array Broadband System

Curvalux is both an advanced multi-beam phased array wireless access and backbone technology with a built in backhaul relay architecture. Curvalux provides frequency re-use, high directivity and gain of the antenna thereby dramatically increasing the throughput and range of wireless broadband connectivity to low powered and low-cost end-user terminals. The next generation 5G mobile systems are also multi-beam phased array technologies but Curvalux beats those systems in terms of mass, size, power and most importantly cost for the fixed wireless access application

Sheffield The Outdoor City

Sheffield is The Outdoor City:

The historic and spiritual home of the Peak National Park, UK climbing; unrivalled downhill mountain biking; infamous road cycling and a hive of activity for kayakers, cavers , walkers and runners of all ability. We recognise that this is not only part of our local character, but it also is about community, health and wellbeing, and we are incredibly lucky to have this resource as part of our urban landscape.

It has not all happened by design – it is partly the result of the city’s unique geography (of which 1/3 sits in the Peak District National Park) but also the amazing clubs, facilities and communities and people who live there because of it. On top of this there is a thriving cultural scene around music, art and beer, which means the nights are as much fun as the days.
