802.15 are popularly
known as WPAN (Wireless Personal area Network). 802.15 entirely deal
with short distance wireless networks and addresses wireless
networking of portable and mobile computing devices. WPAN has laid
down the standards for communication, interoperability of such
in a proximity
IEEE 802.15 working
group addresses the standards for WPANs. It has been split into four
802.15.1: This task group is responsible for developing the standards for
low-power, low-cost, flexible WPANs and is fully based on Bluetooth
Specification and is fully compatible with Bluetooth 1.1.
802.15.2: This task group is responsible for developing recommended practices
on how 802.11 WLAN and 801.15 WPAN can co-exist in the 2.4 GHz band.
Speed): This task group is responsible for developing and
delivering the higher speed WPANs from 10 Mbps to 55 Mbps at a
distance less than 10 meters.
Speed): This task group is responsible for creating standard for
simple, low-cost, low speed WPANs. Data transmission ranges from 2
Kbps to 200 Kbps and uses DSSS modulation in the 2.4 GHz and 915 MHz
ranges. It uses 16 channels in the 2.4 GHz band, 10 channels in the
915 MHz band, and one channel in 868 MHz band.
