WiMAX is a telecom protocol that provides fixed and completely mobile net access. The existing revision of WiMAX supplies up to 40 Mbit/s and the IEEE 802.16m update is anticipated to offer about 1 Gbit/s fixed speeds.The name "WiMAX" was made by the WiMAX Forum, which was formed in June 2001 to push compliance and interoperability of the standard.

Mobile broadband is the name used to explain numerous sorts of wireless fast web access through a transportable modem, phone or other machine. Assorted network standards might be used, example; GPRS, 3G, WiMAX, LTE, Flash-OFDMA, IPW, iBurst UMTS / HSPA, EV-DO and some mobile satellite-based systems.However, typically the term makes reference to EVDO (sister system to CDMA-1).

Universal Mobile Telecommunications System is among the third-generation mobile telecom technologies, which also became a 4G technology. The 1st deployment of the UMTS is the release99 (R99) design.It is specified by 3GPP and is a component of the world ITU IMT-2000 standard. The most typical type of UMTS uses W-CDMA (IMT Direct Spread) as the base air interface but the system also covers TD-CDMA and TD-SCDMA (both IMT CDMA TDD).
