The Difference Between Line Of Sight and Non-Line Of Sight

Earlier wireless technologies (LMDS, MMDS for example) were unsuccessful in the mass market as they could not deliver services in non-line-of-sight scenarios. This limited the number of subscribers they could…

What is Fixed WiMAX ?

Fixed WiMAX offers cost effective point to point and point to multipoint solutions. What makes WiMAX so exciting is the broad range of applications it makes possible but not limited…

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…

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…

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…

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…

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…

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…

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,…

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…

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…

Emergence of Standards-Based Technology

In 1998, the Institute of Electrical and Electronics Engineers (IEEE) formed a group called 802.16 to develop a standard for what was called a wireless metropolitan area network, or wireless…
