| 10 Base-T | Basic Ethernet at 10 Mbit/sec |
| 100 Base-T | Ethernet running at 100 Mbit/sec |
| 1000 Base-T | Ethernet running at 1,000 Mbit/sec |
| 1G | First Generation. Refers to analog cellular systems |
| 2.4GHz | Unlicensed band. Use includes cordless phones, small appliances, wireless video security systems, data modems |
| 2G | Second Generation. Refers to digital cellular and PCS wireless systems oriented to voice and low speed data services |
| 2R | Receive, Reshape (an optical signal) |
| 3G | Third Generation. Refers to the next generation of wireless systems - digital with high speed data. Being standardized by 3GPP and 3GPP2 |
| 5.2 Ghz | Unlicensed band. Use includes cordless phones, small appliances, wireless video security systems, data modems |
| 5.7 Ghz | Unlicensed band. Use includes cordless phones, small appliances, wireless video security systems, data modems |
| 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 |
