Wireless Technology
Wireless and mobile technology has been around for a surprisingly remarkable duration. In 1940, a well-known actress, Hedy Lamarr, and film composer, George Antheil, discussed over dinner a scheme that would permit armed, radio-controlled torpedoes the ability to travel undetected by jamming enemy transmissions. They would patent the invention in 1942 that would later form the basis for what would be known as spread-spectrum communications. Their invention becomes even more incredible when it is taken into consideration that it came before the advent of digital electronics. Now, over 60 years later, spread-spectrum communications has been adapted to today's electronics to allow for an inexpensive way to communicate over long distances, wirelessly. Development of wireless radio technology, through spread-spectrum communication, was a decelerated process throughout the early 1940's when the United States Navy decided to buy into the technology but then decided not to use it and kept it a secret. It was not until the late 1940's that the concept of a cellular phone came to light. A company, which would later be known a Motorola, created a lightweight handheld two-way radio for the United States Army during World War II. Aft
Although some of these network nightmares can be resolved through encryption and the use of passwords, there are some other precautionary measures that can be taken by an organization's IT staff. In 1993, the first digital cellular networks, using spread-spectrum technology, were put into service throughout the United States and Europe. The widespread reliance on networking in business and the growth of the Internet and online services are evidence to the benefits of shared data and resources. In 1970, a professor with the University of Hawaii built upon this technology and created the first radio-based computer network, known as AlohaNet. This is what would eventually lead to the cellular boom. Each device should be thoroughly checked for compliance with the organizations network security protocol, the same as laptop and desktop computers. Soon many advanced features that we know today such as voice mail, fax, paging and text messaging quickly became available to the cellular phone user. WLANs are a type of network that communicates through high-frequency radio waves and infrared rather than using wires. On these "cells" the radio frequencies could be reused which allowed for an increased calling capacity. Cellular phones can now be used as wireless modems for Internet connection while the user is on the move. With proper inspection and enforcement of protected mobile devices, the benefits and invention of spread-spectrum technology of yesterday could mean big returns for corporations today. Many mobile customers are able to connect to corporate networks or intranets by converging on a "hot spot". Problems soon emerged when local radio frequency's quickly filled up with voice traffic and interference. These advanced features and capabilities have paved the road for the eventual direct connection between the wireless world and the World Wide Web.
