The wireless Internet revolution has nearly come full-circle. Wireless technology is quickly approaching the point where wires and cables will be completely superfluous for the delivery of data, the streaming of music and videos, and all manner of other services provided over the Internet. Though there is a great bounty of potential offered by the promise of a fully integrated wireless Internet system, there are several notable obstacles and drawbacks to the implementation of such a system.
Costs
The development of a fully integrated broadband wireless system will take years to construct and implement, at a considerably high cost. Costs associated with wireless Internet include research and development, manufacture of parts and accessories, constructing the transmission systems in outlying rural areas and gathering a staff to administer, beta test and secure such a system. As opposed to Internet service provided through cable and DSL, wireless Internet faces a huge obstacle in delivering service in inclement weather or in unstable atmospheric conditions.
Technology
The technology itself, though technically available on a small scale, needs significant development and testing to scale up the system for a medium to large city to put in place. The city of Minneapolis recently found itself ensnared in a massive boondoggle. A plan to offer free wireless Internet service throughout the city floundered in the planning stages after years of work and millions of dollars spent. The city of Minneapolis has nothing to show for their efforts, because the technology required to make such a system work cannot be slapped together on such a large scale. Beta testing alone should be confined and concentrated to a small, finite space such as a rural proving ground that can be quickly set up and taken down.
Security
One of the biggest concerns with wireless service is the security issues involved. Whereas cable and DSL provide a measure of security through direct transmission of data, wireless Internet broadcasts its signal for the consumption of all. Computers will download data off of this wireless signal, and upload data onto it. Any thief or hacker can easily intercept this signal in transmission and have full access to your data. Also, hackers can use the constant signal to hack into your system and steal data. While this is also a problem with current wired Internet service providers, a wireless system makes it so much easier for criminals to act.
Interference
Another concern with wireless Internet is that simple electronic devices can interfere with its operation. Imagine how a cell phone affects other electronic devices nearby, especially computer speakers. It is the same principle with wireless Internet service. The signal is at significant risk of interfering with other equipment near your computer, and vice versa.
Health Concerns
There are also significant health concerns with wireless Internet service. Much like the uncertainty of whether cell phones can cause certain types of cancer with repeated use, so to are there concerns with wireless Internet being broadcast 24 hours a day throughout cities all over the world.
