802.15.3
An IEEE standard for multimedia streaming over wireless personal area networks.
The 802.15.3 standard purports to connect as many as 245 wireless fixed and portable devices at speeds to 55M bit/sec over distances to 100 meters.
802.15.3, like its other 802.15 brethren and 802.11b networks, operates in the 2.4-GHz unlicensed frequency band. It specifies raw data rates of 11M, 22M, 33M, 44M and 55M bit/sec. The highest rate will reportedly support low-latency, multimedia connections and large file transfers, while 11M bit/sec and 22M bit/sec rates reportedly target long-range connectivity for audio devices. For quality of service, the standard specifies the use of Time Division Multiple Access.
The IEEE says users increasingly want to connect multiple portable devices at low cost, yet run high-bandwidth applications, such as multimedia, digital images and high-quality video. The standard also addresses user priorities such as network economy, frequency performance, power consumption and data-rate scalability, the IEEE says.
To keep costs low the IEEE limited the need for external components and allowed the radio and protocol to appear on no more than two chips that fit within a compact flash card.
