Broadband Internet: WiMAX, LTE, and 3G/3.5G – Article

An article on broadband technologies, specifically, WiMAX, LTE, and 3G/3.5G has been published in website. Though, we can find each of these technologies described separately in their own context, it is hard to compare and contrast the same. The article aims at bringing out the similarities and differences between these technologies.

WiMAX is a wireless digital communications system, also known as IEEE 802.16 that is intended for wireless “metropolitan area networks”. WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 – 10 miles (5 – 15 km) for mobile stations. In contrast, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 – 300 feet (30 – 100m).

The contents of which include WiMAX and its features, architecture, how it works, advantages and disadvantages in comparison with with 3G, 3.5G and LTE. Intel (INTC), Sprint Nextel (S), Motorola (MOT), and Clearwire (CLWR) are all WiMax partners and provide various components of WiMAX such as WiMax chips,  WiMax equipment and handsets.

WiMax is considered most useful for “last mile” connectivity in rural and emerging markets where laying fiber, cable, or DSL is cumbersome or economically not feasible. xDSL is widely used by carriers, because it can provide high data speeds over a dedicated telephone line. ADSL and SDSL reach speeds up to 6 Mbps.

The article also provides a list of broadband equipment providers and service providers such as AT&T, Verizon Communications, Vodaphone, NIT, Earthlink, O2 Broadband, and others.
