Mercury5G Bridges Dual Band Wireless Networks

9 April, 2003 - Synad, the fabless WLAN System-on-Chip (SoC) company, has announced that it is demonstrating to customers its Mercury5G dual mode chipset for 802.11a, b and g wireless standards.

Mercury5G is based on Synad’s AgileRFTM technology, devised by Synad to deliver interoperability between the three 802.11 standards without compromising data throughput, range or performance. The AgileRF technology enables dynamic monitoring and switching between 802.11a, 802.11b and 802.11g, without loss of connectivity to the user, to whichever Access Point provides the optimum service.

“Synad defined the term dual band WLAN and has developed a solution from the ground up. Our early lead in this market has enabled us to develop a highly integrated and optimised dual band solution and customer response shows clear demand for a solution that enables the user to be standards agnostic,” said Mike Baker, CEO, Synad.

Featuring a Mercury5G mini-PCI card in a Windows based laptop PC environment the demonstration showcases Synad’s end to end capability and total solution, from NDIS based drivers through to the form factored reference design including the chipset.

The demonstration highlights Mercury5G interoperability between the 5GHz 802.11a and 2.4GHz 802.11b and 802.11g standards with data transfer across both bands including high quality video streaming.

Mercury5G is standards compliant and this is illustrated through operation with third party access points as well as Mercury5G based cards.

Mercury5G Specification

Mercury5G is a highly integrated two-chip solution, comprising a direct conversion (Zero IF) dual band radio chip and a modem/MAC chip, both fabricated in low cost CMOS technology.

The dual band radio chip features an integrated synthesiser and VCO as well as all baseband filtering. The direct conversion radio architecture avoids expensive external components associated with other techniques.

Mercury5G uses integrated system memory, enabling a very low cost client adapter that requires no external SRAM or flash memory components.

Mercury5G uses optimal partitioning between hardware and software based functionality. By combining hardware accelerators with a powerful ARM CPU, Mercury5G is able to deliver the sustained high speed data throughput demanded yet retain the flexibility needed to adapt to enhancing standards.

Mercury5G delivers the enhanced MAC functionality that is critical to the future of high performance wireless networks.

Powerful security features include hardware accelerated WPA, WEP and AES encryption along with support for 802.1x authentication protocols. The result is high security with uncompromised data throughput.

High quality multi media streaming is supported with Point Co-ordination Function (PCF) and other Quality of Service (QoS) protocols enabled by an advanced Direct Memory Access (DMA) engine that delivers packet prioritisation.

With advanced spectrum management functions that include Transmit Power Control (TPC) and Dynamic Frequency Selection (DFS) Mercury5G offers the ability to meet harsher spectrum regulatory requirements that prevail in many parts of the world, as well as reduced power consumption.
Mercury5G is fully supported by a comprehensive developers kit, including reference designs for common configurations such as mini-PCI and Cardbus32 PC Cards, software drivers, API’s and support tools.
