Wireless broadband is a service that is currently being offered in a variety of locations and formats, the most prevalent of which is WiFi service delivered by restaurants, coffee shops, hotels, and internet cafes. The connectivity is created using a wireless router, which sends out a signal not unlike that of a radio wave. Users connect by enabling the WiFi device on their computer, thereby establishing a connection with the router. Once credentials are provided (passwords, payment information, etc), the user is able to access the internet via this connection.

COST

Some businesses provide the service at no charge, while others may require you to have an account with their ISP, or they will assess a usage fee for the service. Many businesses provide this service to both employees and customers, while others use security features to only allow authorized users onto the network. In some cities, WiFi service is provided municipally, meaning anyone with the ability to connect is able to use the service.

CONNECTIVITY

Depending on the type of equipment being used, the reach of the signal ranges from 150 feet to 300 feet. Those measurements are, of course, for best case scenarios, meaning that the actual distance will vary. There are other components available which will boost the signal, and the furthest known distance for a connection is 327 miles.

SECURITY

Other than issues with connectivity, security is likely the biggest drawback to WiFi service. If security features are not enabled, the information being sent over the network may be obtained and used for unscrupulous purposes. The most common forms of security are WPA and WEP. For free WiFi services, such as municipally offered service, security will generally not be provided, so it is a good idea to have protection software (firewall, spyware, ant-virus, etc) installed.

One way to get around such security issues is to use a data card from a cell phone company, such as AT&T, Verizon, or T-Mobile. Instead of relying on readily available, and perhaps unsecured, WiFi service, one can pay a monthly fee to one of these companies and receive internet access through the respective company's network.

For the cell phone networks, down- and upload speeds will not be as fast, but the network will be more secure. They are a bit costly, starting around $70/month, but if a person is consistently in need of secure service, this may be the best way to go. Essentially, they provide service in all areas in which cell phone service is available, but speeds will vary.
