Intel Corp. has introduced its Centrino mobile technology, which integrates wireless capability into mobile PCs, enabling users to connect to enterprise WLAN systems, as well as public WLAN "hotspots".

The solution includes a new mobile processor, chipsets, and 802.11 wireless network functions that have been tested and validated to work together. In addition to wireless communications, the Centrino technology includes features designed to enable extended battery life, and thinner and lighter notebook designs.

"Our focus on integrating all the elements of mobility allows Intel Centrino mobile technology to deliver an outstanding wireless computing experience and marks the first time we've put a combination of technologies under a single brand," said Intel CEO said Craig Barrett.

"This breakthrough innovation, together with industry-wide investment and Wi-Fi hotspot deployments, brings new computing and communications capabilities to businesses and consumers, adding value to mobile PCs," he added.

Mobile Processor

The Pentium M processor is based on a new mobile-optimized microarchitecture that delivers high performance and low power consumption to enable longer battery life. Key features include Micro-Ops fusion which combines two micro-operation into one to enable the microprocessor to execute instructions faster; Advanced Branch Prediction which is claimed to reduce overall latency; and a Dedicated Stack Manager to reduce the overall number of micro-operations.

The processor is manufactured using the company's 0.13?m process and consists of about 77 million transistors. It has a 400MHz system bus, 1MB low-power L2 cache, and provides support for SpeedStep Technology and Streaming SIMD Extensions II.

Mobile-optimized chipset

The company has also expanded its 855 chipset family to include the 855PM chipset that supports discrete graphics and the 855GM with integrated Intel Extreme Graphics 2 technology.

Both support the company's SpeedStep technology and feature a Deeper Sleep Alert State and an internal timer that automatically turns off the chipset clock when the chipset is inactive. The 855GM chipset also includes a low-power graphics power management mode.

They feature a 400MHz processor system bus and support for up to 2GB of DDR 266 memory, along with support for USB 2.0 and Intel's I/O Hub Architecture.

Also part of the Centrino technology is the PRO/Wireless 2100 Network Connection wireless card which has been designed and validated to connect easily to 802.11b WiFi certified access points. It also supports advanced wireless LAN security including 802.1x, WEP and VPN technologies, and will be software upgradeable to support WPA.
