FLO Air Interface Enables Multicast to Mobiles

The new FLO (Forward Link-Only) Air Interface Specification (AIS) has been ratified by the FLO Forum, an association of wireless industry leaders. The technical requirements captured in the AIS form a foundation for compatibility standardization for FLO based terrestrial mobile multimedia multicast systems.


FLO technology is a new air interface originally developed by Qualcomm with multicasting capabilities designed to increase capacity and reduce content delivery costs to mobile handsets.


The AIS includes a complete description of the Physical layer, which uses Orthogonal Frequency Division Multiplexing (OFDM) and advanced forward error-correction techniques, and a complete description of the Stream/Control and MAC layers, which multiplex a multiplicity of simultaneous multimedia services into logical units distinguishable at the radio interface (physical) layer. The specification enables the delivery of multiple, multimedia streams over the standard TV channel allocation bandwidths while ensuring fast service acquisition, robust performance in mobile fading links, and low receiver power consumption. The AIS, the first technical specification produced by the FLO Forum, will be forwarded to Standards Development Organizations (SDOs) for inclusion in new standards that address the delivery of terrestrial mobile multimedia multicast services to mobile devices.

  • FLO Technology is independent of the cellular network but complements CDMA2000 1X, 1xEV-DO and WCDMA cellular network data and voice services.


  • In September 2005, QUALCOMM announced the first live, over-the-air demonstration of "FLO" (Forward Link Only) Technology delivered to a wireless handset. The demonstration will feature over-the-air delivery and viewing of multiple channels of wireless multimedia content, both streaming video and multicast packet data on a form factor accurate (FFA) handset.


  • In July 2005, QUALCOMM and other key members of the wireless industry announced the establishment of The FLO Forum, a new non-profit industry association that promotes the development of products and services related to the delivery of advanced multimedia services to wireless devices around the world using "FLO" (Forward Link Only) technology.
