1. INTRODUCTION
From the leader in robust, high-performance wireless modules comes the next generation
of low-cost 2.4GHz spread spectrum OEM modules. The Cirronet WIT2450 provides the
unique combination of highly integrated low-cost components with Cirronet’s high
performance, high-reliability RF know-how that has made Cirronet products the first
choice of designers for mission critical applications. With the WIT2450, designers get
that same mission critical reliability and robustness but at a price that allows use in a
wide variety of cost-sensitive applications.
The WIT2450 radio transceiver provides reliable wireless connectivity for either
point-to-point or multipoint applications. Frequency hopping spread spectrum
technology ensures maximum resistance to noise and multipath fading and robustness in
the presence of interfering signals, while operation in the 2.4GHz ISM band allows
license-free use and worldwide compliance. A simple serial interface supports
asynchronous data up to 230400 bps. An on-board 1 KB buffer and an error-correcting
over-the-air protocol provide smooth data flow and simplify the task of integration with
existing applications.
