ABSTRACT:
Inbound channel access is facilitated in a two-way messaging system (FIG. 1) utilizing a frequency-hopped spread-spectrum modulation technique on a set of hopping frequencies. First and second subsets of the set of hopping frequencies are defined (504), the first and second subsets being orthogonal to one another. Scheduled transmissions are communicated (514) on the first subset, and ALOHA transmissions are communicated (514) on the second subset.
