Doodle Labs
Doodle Labs, a leader in ruggedized, industrial wireless networking products, today announced the availability of the carrier-class IEEE 802.11 a/b/g wireless mini-PCI radio modules. These modules are the first ever >1000mW radios that support extended frequency ranges of 4.8 – 6.0 GHz (DLM105) and 2.3 GHz to 2.7 GHz (DLM106), programmable 5/10/20/40 MHz channel width for the operation in the licensed/unlicensed bands (e.g. WiFi, WiMax, Home Land Security, ISM bands).
In addition to the highest-power and extended frequency ranges, the radio modules also feature industry best receiver sensitivity, linear output power amplifiers in balanced mode to deliver high power at lowest EVM (Error Vector Magnitude), advanced filtering for improved noise immunity as part of their industry-leading performance offering. The mini-PCI modules are based on the Atheros 6th generation 802.11a/b/g AR5414A chipset and include advanced features such as Adaptive Noise Immunity, QoS, and latest IEEE 802.11i security standards.
The design of the DLM105 and DLM106 mini-PCI radio modules feature dual MMCX antenna connectors for flexibility in system design with diversity or internal/external antenna selection options. The low loss, rugged MMCX connectors allow for improved mechanical stability and the use of higher quality, lower loss antenna cables. The radios have built-in RF surge protection circuit, which can significantly improve radio reliability in harsh ESD and EMP sensitive environments. The operating temperature range is from -40º C to +85º C.
"The development of these radios was driven by our OEM customers who have been using our radio cards for almost 10 years in various applications deployed around the world," said Raghu PV, General Manager of Doodle Labs. "The feature set bundled in these radios is the result of an accumulation of suggestions and feedback we have obtained over the years from customer interactions and shared field performance experiences."
The DLM105 and DLM106 modules are now sampling and volume shipments will begin on March 1, 2009. The modules will carry modular FCC, IC, and CE approvals (in progress). The radio modules are compatible with Atheros’ Linux MADWIFI and Windows XP drivers as well as various Linux routing operating systems like Antcor Ikarus and Mikrotik.
