pCell uses data centers to calculate the shaping of wireless transmissions to target individual antennas of target users.
LTE networks today achieve a spectral efficiency (SE) of 1.7 bps/Hz. Practical pCell systems today achieve average spectral efficiency of 59 bps/Hz, a 35X leapfrog with unmodified standard LTE devices, such as iPhone 6/6 Plus, iPad Air 2 and Android devices, as well as Wi-Fi devices. pCell’s spectral efficiency scales indefinitely, while remaining compatible with legacy devices.
VenueNext, the mobile services provider for Levi’s Stadium, and other venues throughout the world, is trialing pCell in high-density, high-traffic venues, to enable concurrent usage by 10s of thousands of fans of HD video-rich services and high-bandwidth upstreaming of images and HD video
pCell technology accomplishes this through an entirely new approach to wireless: rather than avoiding interference like cellular or Wi-Fi systems, pCell embraces interference, utilizing interfering transmissions to synthesize a tiny personal cell, a “pCell”, around each individual user device, enabling every user to utilize the full capacity of the spectrum at once. Instead of many users sharing the limited capacity of one cell, resulting in steadily declining data rates as new subscribers join the network, with pCell technology, each user gets a personal cell
