Abstract
Wireless protocols in the unlicensed spectrum are developed for different requirements in terms of transmit range and power, which makes it difficult for multiple nodes having disparate transmit ranges to coexist in the same unlicensed spectrum. A short-range wireless node uses adaptive preambles to signal presence to long-range wireless nodes outside of its transmit range. In addition, a long-range wireless node detects an adapter preamble and backs-off transmissions for reservation period dedicated to short-range nodes.
