Ethernet Direct has introduced the Falcon FWO-800: an industrial 2.4GHz 802.11b/g outdoor wireless mesh system. The Falcon FWO-800 is a cost-effective layer-two wireless mesh product; it comes with a single radio work in 2.4GHz band, two sets of SSID and time division for backhaul and AP operations simultaneously. It comes with a WMM option to enhance user performance and density QoS, supporting bandwidth priority to voice (voice over internet protocol) and image (surveillance/IPTV). The device can be deployed for mobile applications and outdoor and indoor applications, such as city areas, factory plants, communities, campuses, parks, camps, hotels, malls, condos and offices.

IDC Introduces Wireless Call Button IDC has added the wireless-based ZB112 call button to its Zigbee range of interactive paging and call systems products, for use in hospitals, clinics, nursing homes and disabled facilities. The ZB112 is programmable and battery powered, removing the requirement for external power supplies or control cables. The device has extremely low power consumption, enabling it to operate for years without the need to replace batteries in most applications. The ZB112 is designed for use in hospital wards, toilets, bathrooms and rest facilities - anywhere where there is a requirement for patients to call for assistance quickly. It can be sited at any convenient location, as it requires no external cabling. The device integrates a single large button - with the facility for customisation by the addition of further buttons, if required. The button has a tactile feel for ease of operation and offers back lighting when depressed. The ZB112 is programmable and con...

LDMOS Transistors Aid Design Of Wireless Stations Infineon Technologies AG has introduced a range of high-power LDMOS transistors for the design of broadband wireless-network base stations. The transistors, introduced at the IEEE MTT-S International Microwave Symposium, feature power levels up to 300W and video-bandwidth exceeding 90MHz. They support the high peak-to-average power ratios and high data-rate specifications required for the evolution from 3 to 4G wireless networks. The new transistor range achieves higher gain and higher power-density than alternative devices operating in the 1.4 - 2.6GHz cellular bands. This allows the use of packages with a 30 per cent smaller footprint, to enable smaller and lower cost amplifier designs. High peak-power is valuable for Doherty-based amplifier designs, as well as for reducing parts count in other architectures. Illustrative performance of the new transistors, in a two-carrier WCDMA signal at 2170 MHz, 30V, 8dB PAR and 3.84MHz channe...
