IEEE 802.15.3a:

i) The IEEE 802.15.3a has set out to develop a flexible standard which enables high data rate WPAN (110 Mbps at 10 m, 200 Mbps at 4 m, and 480 Mbps at 2 m) using a cost-effective architecture.

ii) The standard enables a broad range of applications including the wireless transmission of images and video. The IEEE 802.15.3a is only concerned with physical layer alternatives and uses the same MAC sublayer as IEEE 802.15.3.

iii) The IEEE 802.15.3a task group established technical requirements and selection criteria for the physical layer (see Table).

iv) The task group set forth goals for low-power consumption and low-cost devices to ensure that the standard could be implemented in CMOS technology.

v) Below Table shows Summary of technical requirements and selection criteria of IEEE 802.15.3a physical layer.

Parameter	Details
Data rates	110, 220, and 480 (optional) Mbps
Range	10 m, 4m and 2 m
Power consumption	100 mW and 250 mW
Power management modes	Capabilities such as power saving, wake-up, etc.
Co-located piconets	4
Interference susceptibility	Robust to IEEE systems, PER <8% for a 1024 byte packet
Co-existence capability	Reduced interference to IEEE systems, interfering average power at least 6 dB below the minimum sensitivity level of non- 802.15.3a device
Cost	Similar to Bluetooth
Location awarness	Location information to be propagated to a suitable management entity
Scalability	backward compatibility with IEEE 802.15, adaptable to various regulatory regions
Signal acquisition	<20 micro seconds for acquisition from the beginning of the preamble to the beginning of the header
Antenna practicality	Size and form factor consistent with original device
