ATM cells are transmitted from base stations to mobile terminals. Mobility functions are performed at an ATM switch in the core network, known as a ''crossover switch'',<ref name="watm5">[http://www.barnesandnoble.com/w/wireless-atm-and-ad-hoc-networks-c-k-toh/1112737100?ean=9780792398226 Book on Wireless ATM Networks] - [[Chai Keong Toh]], Kluwer Academic Press 1997</ref> which is similar to the [[mobile switching center]] of GSM networks.

The advantage of wireless ATM is its high bandwidth and high-speed handoffs done at layer 2. In the early 1990s, [[Bell Labs]] and [[NEC]] research labs worked actively in this field.<ref name="watm10">[https://www.researchgate.net/publication/3233809_WATMnet_a_prototype_wireless_ATM_system_for_multimedia_personalcommunication WATMnet: a prototype wireless ATM system for multimedia personal communication], D.

The forum was supported by several telecommunication companies, including NEC, [[Fujitsu]] and [[AT&T]]. Mobile ATM aimed to provide high-speed multimedia communications technology, capable of delivering broadband mobile communications beyond that of GSM and WLANs.
