WiMAX versus 3G and Wi-Fi
How does WiMAX compare with the existing and emerging capabilities of 3G and Wi-Fi? The throughput capabilities of WiMAX depend on the channel bandwidth used. Unlike 3G systems, which have a fixed channel bandwidth,

Here I write on article How Wimax works and on wimax terminology
Narrowband Wireless Local-Loop Systems
Naturally, the first application for which a wireless alternative was developed and deployed was voice telephony. These systems, called wireless local-loop (WLL), were quite successful in developing countries such as China, India, Indonesia, Brazil,
The Benefit of OFDM & OFDMA in Wimax
Less complex modulation. OFDM is a simpler modulation technique that is better suited to deployments that do not require support for mobility. License-exempt bands. Mobile services require licensed spectrum to provide coverage in wide
why radio in a weather resistant or weatherproof enclosure near the antenna ?
The photo above shows the WiMAX radio deployed in an enclosure. Note from left to right: a) copper grounding cable on the inside of the enclosure b) Ethernet connection to the data source c)
why Most WiMAX solutions use radios separate from antennas ?
At the core of WiMAX is the WiMAX radio. A radio contains both a transmitter (sends) and a receiver (receives). It generates electrical oscillations at a frequency known as the carrier frequency (in WiMAX
Point-to point and Point-to-multipoint configurations
Point-to-Point(P2P) Point to point is used where there are two points of interest: one sender and one receiver. This is also a scenario for backhaul or the transport from the data source (data center,
What is Different Between Wimax & Wifi ?
One of the most often heard descriptions of WiMAX in the press is that it is "Wi-Fi on steroids". In truth, it is considerably more than that. Not only does WiMAX offer exponentially greater
What is Mobile Wimax ?
Mobile WiMAX allows any telecommunications to go mobile. Mobile WiMAX takes the fixed wireless application a step furher and enables cell phone-like applications on a much larger scale. For example, mobile WiMAX enables streaming
What Is WiMAX?
WiMAX is a coined term or acronym meaning worldwide interoperability for microwave access (WiMAX). What WiMAX is however at its heart is a standards initiative. Its purpose is to ensure that the broadband wireless
Wi-Fi Systems
In addition to 3G, Wi-Fi based-systems may be used to provide broadband wireless. Wi-Fi is based on the IEEE 802.11 family of standards and is primarily a local area networking (LAN) technology designed to
First-Generation Broadband Systems
As DSL and cable modems began to be deployed, wireless systems had to evolve to support much higher speeds to be competitive. Systems began to be developed for higher frequencies, such as the 2.5GHz
Evolution of Broadband Wireless
The history of broadband wireless as it relates to WiMAX can be traced back to the desire to find a competitive alternative to traditional wireline-access technologies. Spurred by the deregulation of the telecom industry
