As a result of high installation costs and the desire to optimally place sensor elements without the limitation of wire access, there is a growing need for a reliable, low-cost wireless signaling method. It is now possible to make a 1/10 W spread-spectrum, 912 MHz carrier transmitter. This discussion is limited to the FCC's Part 15 treatment of spread spectrum. Spread-spectrum reliability, jamming performance range, and FCC regulations are discussed. Also, approaches and trade-offs concerning data collisions, fading, and battery life are highlighted.<>
