Broadband Wireless Access (Wi-MAX)


Wi-MAX is an acronym that stands for World-wide interoperability fir Microwave is an ideal method for ISP to deli ever high speed broadband to location where wired connection would be difficult or costly.

Wi-MAX delivers a point to multi-point architecture.It doesn't require a direct line of sight between the source and end point and it has a service range of 50 KMs. It provides a shared data rate of up to 70Mbps,which is enough to service up to a thousand subscriber with high speed access.

The Main advantage of Wi-MAX are

High speed of broadband service up to 70 Mbps.

Wire less rather than wired access,so that it would be a lot less expensive than cable or digital subscriber line and much easier to extend to suburban and rural areas.

Broad coverage like the cell phone network instead of small Wi-fi hot spots, 50 Kms

Wi-MAX Standards

1. IEEE 802.16-2004 is for fixed point to point and point to multipoint wireless access. It is akin to a faster,airborne version of Digital Subscriber Line [DSL] or cable-modem is also called first Non Line-of-Sight, Broadband wireless access [BWA] standard.

2. IEEE 802.16e is for mobile wireless access fir laptops and hand held. It is analogous to a faster version of third generation 3G telecommunication technology.

Working of Wi-MAX

Wi MAX op rates similar to Wi-fi but at higher speeds, over greater distances and for a greater number of consist of following parts

A Wi-MAX tower similar in concept to a cell phone tower and which can provide coverage to a very large area as big as three thousand sq miles.

1. A Wi-MAX receiver and antenna could be like a PCMIA (personal computer memory card international association) card, or they could be built into a laptop similar to Wi-Fi access.

Services Provide

i) The non-line-of-sight Wi-Fi sort of service, where a small antenna on your computer connects to the tower. In this mode Wi-MAX uses a lower frequency range 2 Ghz to 11 Ghz [similar to Wi-Fi]. As lower wavelength transmission are not as easily disrupted by physical obstruction they provided non-line-of-sight coverage.

ii) The Line of sight services, where a fixed dish antenna points straight at the Wi-MAX tower from a rooftop or pole. The line 0f sight connection is stronger and more stable,so it is able to send a lot of data with fewer errors. Line of Sight transmission use higher frequencies,with ranges reaching a possible 66 Ghz. At Higher frequencies, there is less interference and lots more bandwidth.

Wi-MAX Specifications

  • Range 30 Miles radius from base station.
  • Speed 70 Mbps
  • Line-of-Sight not needed between user and base station.
  • Frequency bands: 2 to 11 Ghz and 10 to 66 Ghz.
  • Define both MAC and PHY layers and allows multiple PHY layer specifications.


Wi-MAX is going to provide seamless connectivity throughout the geographical area. It is specially suited to the requirement of rural as well as urban population. This is also provide an alternative media of telecommunication for the poorest and the remotest customer.
