Small Wireless Transceivers

Dec. 1, 2003
The XE900S family of smart wireless transceivers relies on Frequency Hopping Spread Spectrum (FHSS) technology to improve performance and reduce size for use in embedded remote data acquisition and remote monitoring applications.

The XE900S modules can be used to construct point-to-point or point-to-multipoint networks with up to 254 nodes. At 1.295-by-1.41-by-0.255 inches, the XE900S-500 and XE900S-10 modules are 40 percent smaller than the smallest competitive products, the vendor contends. The XE900S-10 has output of 1-10mW and power dissipation of 50mA at 3.3 volts with a 1mW transmit level, resulting in operational range of 200 feet, even through physical obstructions. Power output for the XE900S-500 is adjustable from 100 to 500mW. Power dissipation is 100mA at 3.3 volts with a 100mW transmit level, producing an obstructed operational range of 800 to 1,500 feet, the vendor says. Another module, the XE900SL-10 is provided in a smaller package, at 1-by-1-by-0.26 inches, with performance similar to the XE900S-10.
