WIT910 - 4/10/08

Powerful

With a full 1/2 Watt transmit power and a receive sensitivity of -103dBm, the WIT910 can achieve ranges in excess of 20 miles using 3dB omni-directional

antennas. When long range isn’t needed, the WIT910, measuring just 80.2mm x 46.5mm x 8.6mm and weighing just 35 grams is a powerful performer at

low power, consuming less than 100mA at 3.3 volts.

With the same size and mounting dimensions of the industry-leading WIT2410 module, the WIT910 can be used in place of the WIT2410 in existing designs,

creating a 900MHz product with practically no development effort.

Versatile

All of the module parameters are configurable under software control. Even transmit power can be selected through a straightforward command set. Point-

to-point and point-to-multipoint modes are supported. Standard communication rates between the 910 and the host are supported between 1200 bps and

57.6 Kbps. Non-standard rates are supported as well.

Reliable

The WIT910 provides both reliable communication and reliable operation. With Frequency Hopping Spread Spectrum technology, the WIT910 provides

immunity to jamming as well as immunity to multipath fading. Using Automatic Retransmit Request (ARQ) in addition to a 512 byte buffer, transparent error-

free communication is automatic. The built-in data scrambling adds a measure of security.

Reliable operation is assured through our stringent QA processes. All WIT910s are manufactured in an ISO9000 certified facility; another reason

CIRRONETTM is the choice of hundreds of designers.

Simple

Simple to use and simple to integrate. Although the WIT910 offers great flexibility, the factory default settings work for many applications. For those other

applications, software control makes changing settings simple.

The WIT910, with its small size and low power consumption, is simple to integrate into your product. The RS-232 style interface with standard CMOS signal

levels makes the electronic integration easy. Since the WIT910 is FCC certified, your 910-based product does not have to repeat the FCC type approval.
