LTE is now a market reality and is becoming firmly entrenched as a wireless network standard in markets all over the world. A recent report from the GSA (Global Mobile Supplier Association) stated that the number of commercial LTE networks now stands at 105, deployed across 48 countries. It is anticipated there will be 195 deployments by the end of 2013.
The progress of network development has been rapid. While some operators are still in the trial phase, the first movers to the technology have already deployed commercial ‘voice over LTE’ (VoLTE) services to their subscribers.
According to ARC Charts there will be over 74 million VoLTE enabled handsets in the market by 2016. So far, the delivery of LTE has been reliant on a ‘best-effort’ model to 4G service islands with a fallback in place to 3G networks. However, this will soon be replaced with a fully integrated VoLTE system with a stringent requirement for quality of service (QoS) tolerances to deliver premium quality voice.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
