Spread-spectrum radio made affordable at last
Available now from Low Power Radio Solutions, the LX2400 is the first in a new family of ultra-low-cost spread-spectrum radio modules from AeroComm.
Wideband transceiver prolongs battery life
The STD-403 is a fully self-contained eight-channel wideband transceiver module optimised for low-power-consumption high-speed half-duplex telemetry applications
A typical setup can comprise a basestation communicating simultaneously with up to six mobile units, each capable of reliable operation at ranges up to 300m line-of-sight.
DECT brings its own advantages to the low-power radio market, in particular a combination of a relatively unused part of the radio spectrum, together with a full set of embedded full-duplex communications protocols.
According to LPRS Managing Director Barry Gillibrand, it is this that is most likely to appeal to users: "Particularly in complex data-telemetry applications, communications protocols have been a weak link in low-power radio systems.
With DECT, all the protocols are defined and the system is effectively ready to use".
Operating in the DECT allocated band between 1.88 and 1.9GHz also brings benefits when compared with the highly populated 2.4GHz spread-spectrum band which is fast becoming heavily populated with the increasing uptake of Bluetooth systems.
As a result, users can expect reliable operation and, as the DECT spectrum is defined worldwide, designers can produce a single radio system for world markets.
Data transmission rates range from 32 to 192Kbit/s, including the ability to operate in quasi-full-duplex mode, and all data are protected.
In addition, unlike most low-power systems, the DataDECT 251 can also be used for speech transmission.
Modules are particularly compact, measuring just 63 x 35 x 7mm.
Power consumption is also low, with a typical quiescent current drain of less than 100mA from the unit's 3.3V supply, making them ideal for battery-powered portable applications.
Modules are available now, starting at around ?50 in 1000-off quantities. Request a free brochure from Low Power Radio Solutions ...
