An increasing number of businesses, municipalities, and individuals are seeing the benefits of wireless Internet access. It’s really no wonder that this type of technology is growing increasingly popular because of its flexibility and the fact that it offers an economical way to put a lot of different devices and their users onto the Internet or a Local Area Network. Wireless hot spots are great for flexible use and varying numbers of users. After all, how could there be a better way to supply Internet access to all of the computers in an office, as well as the laptops and Blackberry type devices that employees bring in and use on a variable basis? The same flexibility makes wireless hot spots an attractive thing to install in coffee shops, airports, libraries, and even homes.There are currently several widely available varieties of wireless Internet access. The most common by far is Wi-Fi. Wi-Fi is a short range type of wireless networking that’s commonly associated with the wireless hot spots you’d find in a coffee shop or bookstore. It’s extremely cost effective and easy to set up just by hooking a wireless router into a broadband Internet connection.G3 is another popular way to get onto the Internet wirelessly. A G3 network uses technology that’s similar to the cellular technology that allows for the used of mobile phones. G3 technology allows smart phones and laptops to connect to the Internet over cell phone towers and while moving at extremely fast speeds like on a train or in a car(the Doppler effect can ruin some types of wireless connections even at relatively slow speeds) and over a very wide area. It’s been the technology of choice for professionals who need to stay connected while on the go.Now there’s a type of wireless technology that could serve as severe competition to G3. This type of technology is called WiMax and it combines many of the best points of both Wi-Fi and G3 technologies. Like G3, WiMax can operate over extremely large distances- up to 30 miles. Like Wi-Fi, WiMax is extremely effective indoors- which is something that G3 technology doesn’t do so well. WiMax is also much faster than Wi-Fi. The combination of speed and large coverage area makes WiMax extremely effective for providing large numbers of people with high speed Internet access.One thing that WiMax doesn’t do as well as G3 is provide mobile Internet access. That’s because at the frequencies that WiMax carriers are currently licensed to operate at the Doppler effect is an issue, while the frequencies that G3 is licensed to use aren’t as effected by the movement of the user.However, this shortcoming of WiMax compared to G3 is simply a regulatory issue. WiMax would be just as good for mobile devices as G3 is if it was licensed to use the same frequencies. And there lies the major explanation for why it hasn’t been widely adopted yet- lobbying on the part of companies that have a lot invested in G3 networks and don’t want the competition of a technology that could serve more people in a wider variety of ways.Of course there is the hope that the two technologies will be able to coexist- even possibly in the same devices- so that they can be used in the situations that suit them best.
