What is Functions of the ASN in Wimax ?
ASN – Access Service Network. Establish layer 2 connections between the BS and the MS. Transmit AAA messages to the home NSP of the MS. Assist the high level to…

Here I write on article How Wimax works and on wimax terminology
What are the Advantages of OFDMA in Wimax ?
OFDMA is essentially a hybrid of FDMA and TDMA: Users are dynamically assigned subcarriers (FDMA) in different time slots (TDMA) . The advantages of OFDMA start with the advantages of…
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…
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…
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,…
