DIGITAL WIRELESS CORPORATION OEM MODULE
WIT2400 Frequency Hopping Transceiver OEM Module
Based on wireless expertise developed over the last 10 years, the WIT2400 is the ultimate OEM solution for wireless products. Operating in the unlicensed 2.4GHz ISM band, the WIT2400 combines extraordinary range with immunity to both jamming and multipath fading. With both FCC Part 15 and ETSI 300.328 compliance, the WIT2400 can be used anywhere in the world - license free. All in a small, simple to integrate package. And best of all, the WIT2400 has been FCC certified with a variety of antennas. This means your product will not have to undergo FCC type approval. Reliable. The WIT2400 provides both reliable communication and reliable operation. With Frequency Hopping Spread Spectrum technology, the WIT2400 provides immunity to jamming as well as immunity to multipath fading. Utilizing Automatic Retransmit Request (ARQ) in combination with a 6KB buffer, transparent error-free communication is automatic. The WIT2400 has built-in data encryption adding a measure of security to the reliability. Reliable operation is assured through our QA processes. All WIT2400s go through a full 48-hour burn-in. And compliance with ISO9002 is on schedule for completion by Q2 `99. With thousands of units in the field, the WIT2400 has a proven track record of reliability. Flexible. The WIT2400 gives you the systems designer the flexibility to tailor the WIT2400 to your application. Practically all variables are under your software control. Even transmit power can be selected through software. Need guaranteed channel availability? No problem. Simply select TDMA mode rather than CSMA. You can also choose between synchronous and asynchronous communication. Standard communication rates between 1200 bps and 115.2 Kbps are software selectable as well as nonstandard rates. The WIT2400 supports point-to-point and point-to multipoint modes. And with multiple hopping patterns, co-locating systems is not a problem. Simple. Simple to use and simple to integrate. Although the WIT2400 provides great flexibility, the default settings work for many applications. And those settings to be changed are modified through a straightforward command set. The WIT2400 is simple to add to your product. Its small size and low power consumption reduce the

impact of the radio on your system design. And its CMOS signals make the electronic integration easy. Add the fact that your WIT2400-based product does not have to repeat the FCC type approval, and you have the solution to get your product to market much more easily, quickly and less costly than designing your own. Let us be your experts. The WIT2400 lets you be an expert on your product and lets Digital Wireless be the expert on wireless transceivers.
