WiMAX
WiMAX technology, also known as 802.16, will hit the market in 2005 and will function as a wireless alternative to cable modems and DSL. WiMAX plans to offer wireless connectivity up to 30 miles from an antenna at speeds of up to 75 mbps, cable modems bring in data at just over 1 mbps. WiMax, which carriers can use to wirelessly deliver broadband, will include the 802.16 standard, plus revisions and additions.
Wi-Fi
Also known as 802.11, AirPort and wireless LAN, Wi-Fi is a wireless network connection that uses a high-bandwidth radio transceiver to tap into networks at speeds of 11 mbps to more than 100 mbps, up to 350 feet from a base station. Wi-Fi cards most commonly found in laptops have the specifications 802.11a, b, and g. These three standards tap into different frequencies and allow for varying bandwidths. Most new cards can work with multiple standards.
TDMA
Division Multiple Access (TDMA) is a digital wireless service that divides a radio frequency into time slots and then allocates the slots to multiple calls, allowing a single frequency to support multiple, simultaneous data channels.
PCS
Personal communication service (PCS) is a second-generation mobile communications technology also referred to as digital cellular. The digital service, which works over CDMA, GSM and TDMA interfaces, operates at the 1900 MHz frequency range and can be used internationally.
iDEN
Digital Enhanced Network (iDEN) uses TMDA technology to provide cell phone voice communication, messaging, digital two-way radio and data transfers.
GSM
Global System for Mobile Communications (GSM) is a digital cellular system that uses TDMA, which allows a single frequency to support multiple, simultaneous data channels.
EDGE
Enhanced Data GSM Environment (EDGE) is a faster GSM wireless service that can deliver data at rates up to 384 Kbps on a broadband. The standard is based on the GSM standard and uses TDMA.
EV-DO
Evolution-Data Optimized (EV-DO) is a high-speed wireless data connection on a CDMA network. The technology allows users to access high-speed Internet through portable devices, such as cell phones, laptops and PDAs.
CDMA
Code Division Multiple Access (CDMA) is a digital wireless service that transfers data at rates from 40 to 144 Kbps. Unlike GSM, which assigns a specific frequency to each user, CDMA allows every channel to use the full available spectrum, allowing greater capacity and higher audio quality for more users.
802.20
Currently in development, 802.20 promises all the benefits of WiMAX 802.16, but it will be optimized for broadband wireless access while traveling at high speeds.
3G
3G is an International Telecommunication Union (ITU) specification for the third-generation mobile communications technology that was created for high-speed transfer of data and multimedia content, such as video, downloads, music and interactive games. 3G aims to increase bandwidth up to 384 Kbps when a device is stationary or moving at pedestrian speed, 128 Kbps in a car, and 2 Mbps in fixed applications. 3G will work over wireless air interfaces, such as GSM, TDMA, and CDMA. The new EDGE service was developed specifically to meet the bandwidth needs of 3G.
HSDPA
High-Speed Downlink Packet Access (HSDPA) is a 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity. Current HSDPA deployments support down-link speeds of 1.8, 3.6, 7.2 and 14.4 Mbit/s. Further speed increases are planned for the near future. The networks are then to be upgraded to Evolved HSPA, which provides speeds of 42 Mbit/s downlink in its first release.
UMTS
Universal Mobile Telecommunications System (UMTS) is one of the third-generation (3G) cell phone technologies, which is also being developed into a 4G technology. Currently, the most common form of UMTS uses W-CDMA as the underlying air interface. It is standardized by the 3GPP, and is the European answer to the ITU IMT-2000 requirements for 3G cellular radio systems.
HSUPA
High-Speed Uplink Packet Access (HSUPA) is a 3G mobile telephony protocol in the HSPA family with up-link speeds up to 5.76 Mbit/s. The name HSUPA was created by Nokia. The 3GPP does not support the name 'HSUPA', but instead uses the name Enhanced Uplink (EUL).
