Report on Wimax

Is social media safe enough for schools to allow students to use it on their school WiFi? Or is it too threatening? Why should schools allow students to use their WiFi for social media? Numerous schools restrict students from using social media on their WiFi by blocking them from being used. Although schools currently block social media on their WiFi to ensure student safety, social media should be unblocked on the school WiFi because it can guide students to become more knowledgeable about opportunities in their school, classrooms can use it in their schoolwork, and when abstained from use by high users it can evoke anxiety and depression.

This is a direct extension of the 802.11b that extends the maximum data rate to 54Mbps, making it possible to serve up to five times as many users. Our Wi-Fi network is based on the IEEE 802.11 b/g standards, which is the most commonly used standard. We have added Wi-Fi access points in our network to give easier access to corporate data and services. Most of the devices in this network, for example the personal computers, smartphones, digital cameras, tablets and digital audio players connected using the Wi-Fi technology. The hotspot will be in the range of 20 meters (66 feet) indoors and a greater range outside.

WiMAX can transmit speeds up to 50km at 280mbps, and provides options for use in point to point and multipoint configurations.

Wireless DSL is a type of fixed wireless which requires a line of sight between communicating transmitters. Unfortunately; this makes its application limited, because in order to be effective, it requires tall buildings or towers. Most multitenant buildings such as hotels, remote office buildings and apartments use this. Transmitters are what connect the building to the ISP, and the DSL used inside the building connects to the wireless transceiver. Fixed wireless can be point to point or multipoint. Satellite is another form of fixed wireless. Both the point-to-point and multipoint versions have data transmissions ranging from 1.5 to 54 Mbps, dependent on the vendor. Mobile wireless service can be set up by the provider in a package one the WAP network protocol is fixed to support it. (Wireless Application Environment) (Fitzgerald, 349-350).

20. __________ are built by attaching a wireless access point (WAP) to the edge of the wired network.

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

5G is the fifth generation wireless broadband technology based on the IEEE 802.11ac standard. 5G is provide high speed then 3G and 4G. 5G operates on 5GHZ signal and set is to offer speed up to 1 GB/s.

wireless network and the most widely available wireless broadband network in the country. The U.S.

1. 40 Mhz bandwidth (channel bonding) which can get data rates as high as 600Mpbs which is a ten-fold increase as compared with 802.11 a thru g.

It’s very important to determine the device and application requirements based on bandwidth, protocols and frequency. In wireless network, bandwidth, protocols and sometime environmental conditions affect the speed of the channel so we need to calculate the aggregate throughputs before designing the network. Today, users carry Wi-Fi devices such as notebooks, laptops, tablets and Smartphone’s so total throughput must be calculated by estimating number of connections rather than the number of the seats. Some common wireless networking standards such as 802.11a/b/g/n invented in the IEEE association must be supported by wireless network. For better performance and for faster devices (802.11n devices), dual-ratio access points should be deployed. Table1 [3] illustrate the different IEEE standards and throughput.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

The improvement of innovation is making a wide range of things should be possible all the more effectively. Included is a technique for conveying information to one or different PCs on the double. Perhaps we are a layman, don 't see how the procedure of the conveyance or dispersion of the information, in subtle element. Generally we know just restricted utilization of the fibre optic link in the conveyance process information. Also, and still, after all that just quickly information. As Human nowadays, Internet is already be part of our lives. An internet connectivity is a must in this modern era due to the technology that has grown rapidly. Wi-Fi has been with humans for about 30 years. And the first Wireless Technology introduced was the WaveLAN. And from that moment, the name of Wi-Fi became booming around the world and human uses a lot until now. Li-Fi was invented by Harald Haas from the University of Edinburgh, Scotland in 2011, when he exhibited surprisingly that by flashing the light from a solitary Drove, he could transmit significantly a larger number of information than a cell tower (Crew 2015). This technology has been demonstrated at the 2012 Consumer Electronics Show in Las Vegas using a pair of Casio 's smartphone data exchange by using light of varying intensity were released from their screens , were detected at a distance of up to ten meters. Which then this points to a question of many people asking, is Wi-Fi generation will be

Wireless Local Area networks (WLANs) have been employed to add mobility features to office and campus networks since the late 1980s. This article presents a discussion of the current state of WLAN technology and some of the products available.

Some of the benefits of WiMAX compared to T3 over SONET connection are that a single WiMAX station can serve hundreds of users, it has a much faster deployment of new users comparing to wired networks, and it can reach a speed of 10 Mbps at 10 kilometers with line-of-site customers. It also supports Non line of Sight customers; it is standardized, and same frequency equipment should work together and it has short delay. Drawbacks of WiMAX are that weather conditions like rain could interrupt the signal; other wireless equipment could cause interference, multiplied frequencies are used, WiMAX is a very power intensive technology and requires strong electrical support, and it has high installation and operational costs.

WiMAX technology has been approved by Bangladesh Government in last quater of 2008 in Bangladesh. Use of this technology has been increased through the passage of time. WiMAX combines the performance of Wi-Fi with the range and quality of service (QOS) of a carrier-grade cellular technology. WiMAX networks can be as small as single base stations with a few subscriber units, to much larger networks with thousands of users. 4G WiMAX gives us incredibly fast wireless access to the internet from four to ten times faster than 3G wireless. WiMAX technology will allow the subscribers to enjoy the amazing experience of high speed internet along with data, voice and video.There are few WiMAX service provider in Bangladesh, among them
