Wireless Messaging System Overview
The Wireless Messaging System (WMS), the Motorola two-way advanced messaging solution,
is part of the FLEX family of protocols. The FLEX protocol is the high-speed, standard
protocol in the one-way paging industry. The ReFLEX messaging protocol includes a
reverse channel to support two-way messaging. The InFLEXion messaging protocol is a
robust two-way voice and data messaging protocol.
With small, lightweight, low-power subscriber pagers, ReFLEX- and InFLEXion-based
services offer many advantages:
High transmission speeds, up to 6400 bits per second (bps) for more than 140,000
alphanumeric pagers per channel
High resistance to signal fading
Two-way messaging including ReFLEX messaging protocol (text messaging), InFLEXion
messaging protocol (voice messaging), message receipt acknowledgment, and message
retransmission
Ability to change speed to match the system daily traffic pattern
Extended pager battery life
