Worldwide Standards for Gb/s WPAN Using the 60 GHz Unlicensed Band
[attachment=22699]
Motivation for Gb/s Standards
Ever increasing amount of digital data for consumer applications
High definition uncompressed streaming video*
Interactive gaming
Digital photography
Digital home movies
Data and file transfer
Present wired standards/data rates
Wired: de facto standard presently for high data rates
Gigabit Ethernet- 1 Gb/s for consumer, typical interoffice
Firewire/IEEE 1394 - 400 Mb/s to 800 Mb/s (rates up to 3.2 Gb/s defined)
DVI/HDMI – 3.986 Gb/s to 4.5 Gb/s ( 10.2 Gb/s for versions 1.3a and 1.3b)
USB 2.0 (Hi-speed) 480 Mb/s
Present deployed wireless WPAN/WLAN standards/data rates
802.11 b/g/n –
.11n advertises rates up to 300 Mb/s
Note that these are maximum data rates
Sustained rates are usually ½ or less than the max
Recent benchmarking of several commercially
available systems indicate maybe ¼ advertised
rate is more accurate
Notable features and accomplishments:
Channel Model
Developed comprehensive indoor model based on measured data for line of sight (LOS) model
NLOS model derived from LOS model and verified through selective measurement
Required an large amount of resources and time to complete
Implemented in MATLAB
Recommended for Tgad 60 GHz model
WirelessHD
WirelessHD
Formed in 2006
Generate next generation specification for consumer targeted A/V applications
Coalition includes: Intel, Broadcom, LG, Panasonic,
Sibeam and others
Lots of press, hype, CES “demos” and so on
Specification released January 2008
First generation production chip set – limited availability and access
Key features: OFDM exclusively, beam steering (low rate PHY only)
