PureWave to supply pWave radios for Artemis

Monday 24 February 2014 | 14:15 CET | News

US start-up Artemis Networks and Wimax equipment manufacturer PureWave Networks have been working together on the design and development of the base stations for Artemis' recently announced pCell technology. PureWave has been selected by Artemis to supply the pWave radios for its upcoming trial deployments, and will supply pWaves in various bands and power levels to wireless carriers that deploy the pCell System, both for initial deployments and to add additional capacity using the same spectrum as mobile data demand continues to grow. PureWave's design leverages the new TCI6630K2L System-on-Chip (SoC) from Texas Instruments, combined with TI’s new analog front end transceiver, the AFE7500.

The pCell software-defined radio C-RAN is connected through fronthaul to pWave radios distributed throughout the coverage area. In a pCell system, the radio signals from pWaves deliberately interfere, so as to synthesize a 1 cm diameter ‘personal cell’ (a pCell) around the antenna of each standard, off-the-shelf LTE device (such as iPhone, Android phones, tablets and dongles) in the coverage area. As result, each LTE device can utilize the entire spectrum concurrently.

At Columbia University, Artemis Networks has recently demonstrated a pCell system streaming multiple 4K Ultra HD video streams at once, using off-the-shelf Release 8 LTE dongles each concurrently using the same 10 MHz of spectrum.

Since pWave radios deliberately interfere with each other, they do not need to be deployed in a specific plan to avoid interference, but rather are deployed ‘serendipitously’, wherever it is convenient and there is minimal site and fronthaul cost, whether indoor, outdoor or both.

Using the same spectrum, each additional pWave radio adds to the aggregate capacity of the pCell coverage area, so as mobile data usage grows, the carrier simply adds more pWave radios to the coverage area.
