In many modern data networks the Random Multiple Access (RMA) is used to arbitrate access of the large user population to a shared broadcast channel. IEEE 802.16-based systems allow of RMA when transmitting the bandwidth requests prior to the scheduled data transmission. In GSM networks RMA is used similarly in the GPRS mode. In the networks which are built over IEEE 802.3 and IEEE 802.11 telecommunication standards RMA directly arbitrates the transmission of the data packets. For the moderate values of arrival rate (of data packets into the system) RMA allows of reaching an unrivaled efficiency in comparison to the other known channel access techniques.
