Small Wireless Transceivers

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.
