Artemis unveils pCell technology to boost LTE capacity

US start-up Artemis Networks has unveiled a new small cell technology aimed at boosting capacity in congested cells. The pCell technology was first demonstrated publicly at Columbia University on 19 February, and the company said it is already in trials in San Francisco and will be ready for its first commercial deployment by the end of 2014. 

pCell uses simple base stations called pWave radios, that, rather than having their placement restricted to a cell plan, can be placed anywhere convenient, whether outdoor, indoor, visible or hidden. For example, locations can be chosen where there is free or low-cost rent and backhaul. pCell works in all mobile bands, as well as in unlicensed spectrum, such as 900 MHz in the Americas, sharing spectrum with other unlicensed devices, enabling deployment by both major carriers with licensed spectrum as well as local entrepreneurs using unlicensed spectrum. 

pCell avoids the problem of interference from other radio signals in a cell by combining transmitted radio signals from multiple pCell base stations to synthesize tiny "personal cells", or pCells, around each mobile device. So rather than hundreds of users taking turns sharing the capacity of one large cell, each user gets an unshared pCell, giving the full wireless capacity to each user at once. pCell is compatible with standard, unmodified LTE devices.
