4M Wireless to Exhibit 3G/4G Multimode User Equipment Operation at MWC


4M Wireless, a supplier of software solutions for mobile communications, will be demonstrating 3G/4G multimode User Equipment (UE) operation on the MIPS architecture at the Mobile World Congress 2011.


The 4M Wireless PS100 LTE (News - Alert) Protocol Stack is a 3GPP Release 8 compliant implementation of the LTE protocol stack for User Equipment (UE) terminals. It consists of a fully optimized Layer 2, Layer 3 and NAS LTE protocol software enabling the highest uplink and downlink data rates. This protocol stack will be demonstrated on a MIPS32 24K core running the Android (News - Alert) operating system to underline the seamless bi-directional handover between a 3G WCDMA protocol stack and 4M Wireless’ 4G LTE protocol stack.

4M Wireless intend to cater to SoC developers need for a high-performance, low-power processors with optimizations for 3G/4G multimode protocol stacks so that handsets built using them are capable of supporting both 4G and 3G technologies.

Designed to power through graphics, Java and demanding code and with features like an ultrafast multiply, intelligent caches, floating point support and the CorExtend capability—which allows users to supercharge application performance by defining and adding their own instructions—the MIPS32 24K architecture is alleged to be the ideal choice for performance driven applications.

MIPS expressed excitement by the traction it is seeing for the MIPS architecture in the mobile market. To speed further penetration into this huge and fast growing market, it is building reference designs and optimizations for all of the key protocol stacks, operating systems and other technologies needed for its customers' development efforts.

4M Wireless is claimed to have shared benchmark results of its LTE protocol stack running on the MIPS-Based Android platform, achieving LTE CAT4 data throughput with packet sizes as low as 128 bytes over a lossy channel simulating a 10 percent transport block loss rate.

Atif Malik, CEO of 4M Wireless commented that the 4M Wireless LTE stack is the industry's most mature stack available today. It is optimized for embedded performance and integrated in several commercially available customer products.

Malik added that the company is delighted to work with MIPS to show such great results of its LTE stack running on a MIPS-Based Android platform, and is looking forward to continued cooperation with MIPS in bringing its technology to other MIPS licensees' platforms.
