Is Microwave the future of Wifi?

WiMax (Worldwide Interoperability for Microwave Access) isn’t new technology (the WiMax forum was created in 2001 to promote the standard), but it’s only recently that it has made people sit up and pay greater attention. According to Robert Morrow, a retired Air Force Academy electrical engineering professor, Wifi and cellular data are on the way out because the future belongs to WiMax. There are others, however, who are not quite as glowing in their praise of the emerging WiMax technology, and who believe that it will prove too expensive to have any real practical value.

In an article for LiveScience, Morrow explains why he believes WiMax is the way of the future. Even though WiMax will not be free, as Wifi is, it offers uninterrupted service. Its reach is longer than WiFi’s (several kilometres as opposed to several metres) and its signal is stronger, although this is dependent on the distance from base station antennaes piso wifi pause time what is 10 0 0 how do i unpause-a device from my wifi. In theory, users should be able to stay connected online all the way across the united states without losing signal once, a feat which is currently impossible even with mobile phone technology. This is because WiMax is compatible with a range of digital cellular service providers, and not just with one or two.

While WiMax doesn’t currently enjoy wide spread use, Morrow believes that within the next 2-5 years it will be commonplace in all major US cities, and that in 5 years time, it will be sold with all laptops, or none of them. Which seems rather contradictory, but he says that WiMax’s ultimate success will depend on how quickly laptop vendors will add WiMax modems to their products.

David Jarvis, a South African telecoms entrepreneur, is one those people who still believes in the power of Wifi. At the 2007 WiWorld Conference, Jarvis said that Wifi is still a more affordable alternative to WiMax. According to Jarvis, a WiMax base stations costs around $35, 000 (£17, 703) to build, while a Wifi station costs a mere $2, 500 (£1, 264). The CPE price of Wifi is also lower, $250 (£126) vs. $350 (£177) for WiMax. Other factors favouring Wifi include its already widespread adoption and the fact that it’s available in commonly used wireless devices.

The Wireless Access Providers’ Association of South Africa (WAPA) has compiled a list of reasons why Wireless Internet service Providers (WISPs) prefer Wifi, such as the tried and tested capability of Wifi. WiMax has yet to prove itself capable of living up to expectations and to justify the price increase from Wifi. In addition, the use of both technologies in the far east has shown that Wifi is superior to WiMax as a business model. Technology has revolutionized our life. The twentieth century has led to a series of technological innovations that dramatically reshaped the way people communicated at a global level. New means of communication speeded the pace of life and people started looking for more convenient ways to do things easily. This brought in portable and anytime accessible laptops with a standard wireless networking as known as Wifi.

Wifi, a widely used technology in wireless communication, is a local area network that uses high frequency radio signals to transmit and receive data over distances of a few hundred feet. It provides wireless access to applications. It was in 2002, the information technology industry made a break through with the launch of a product that worked on new standards. Today, we have Wifi signal strength meters developed on IEEE 802. 11 standards.

Wifi provides its users the freedom of connecting to the Internet from any place. They can use any device such as a personal computer, video game console, smartphone or digital audio player from their home, office or a public place without the hassles of plugging in the wires. Wifi is quicker than the conventional modem for accessing information over a large network. Using different amplifiers, the users can easily change their location without any disruption in the network access. The location where the users can connect to the network is called a Wifi hotspot. There are different Wifi software tools available in the market. They are specifically designed for different types of networks and operating systems. Some of them are Aircrack-ng, NetStumbler, OmniPeek, Stumbverter, Wifi Hopper, and APTools.

Wi-Fi uses radio frequency waves to transmit data between its nodes. These frequency waves are transmitted in the radio bands of 2. 4GHz to 5GHz spectrum that are similar to television signal transmission. It offers a safe and consistent connectivity. It is proved that 802. 11g is a better technology that provides a comprehensive platform for operating Bluetooth strategy, cellular phones, and other scientific equipments. Furthermore, it also provides excellent streaming quality of video, audio and voice channels.
