| 802.11.x |
Specification for wireless LAN technology; over-the-air
interface between wireless client and base station, or between two
wireless clients. Provides 1 or 2 Mbps transmission in 2.4 GHz band;
uses either frequency hopping spread spectrum (FHSS) or direct
sequence spread spectrum (DSSS) (vs. orthogonal frequency division
multiplexing encoding in 802.11a. Developed by IEEE in
1997 |
| 802.11a |
Developed by IEEE in 1999, this specification provides up to
54 Mbps transmission in 5GHz band; typically flows at 6, 12 or 24
Mbps; uses orthogonal frequency division multiplexing encoding
scheme (vs. FHSS or DSSS in 802.11) Developed by IEEE in
1999 |
| 802.11b |
IEEE Wireless LAN system providing throughput of about 11
Mbps |
| 802.11g |
Improvement over 802.11b, increasing bandwidth to 54Mbps.
See WiFi |
| 802.15.x |
See Bluetooth |
| 802.16.x |
Specification for fixed broadband wireless MANs that use
point-to-multipoint architecture. Operates between licensed 10GHz
and 66GHz and between 2GHZ and 11GHz (licensed and unlicensed)
frequency ranges. aka "WirelessMAN™" or "Air Interface Standard".
Defines MAC layer that supports multiple physical layer
specifications customized for frequency band of use and associated
regulations.Supports very high bit rates in both uploading to and
downloading from base station up to 30 miles for such services as
VoIP, IP connectivity, TDM voice and data. Developed by IEEE in
2002 |
| 802.16a |
Iteration of 802.16, allowing devices within 802.16 standard
to support lower frequency ranges – 2GHz-to-11GHz band – to offer
less-expensive services to consumers. Lower frequency spectra will
result in lower data rates, making services more likely to target
homes or small-to-midsize enterprises |
| 802.1P
Prioritization |
Ethernet Layer 2 control for traffic prioritization, dynamic
multicast filtering. Supports time-sensitive applications such as
VoIP |
| 802.1Q
Tagging |
Ethernet Layer 2 controls. Determines how to break large
amounts of data so broadcast and multi-cast traffic won't grab more
bandwidth than necessary. Establishes standard method for inserting
VLAN membership information into Ethernet frames |
| 8PSK |
Phase Shift Keying (PSK) with 8 states, allowing the coding
of 8 bit combinations. It is used in EDGE |
