Radar Detector :: Speeding Driving Technology Essays

Radar Detector Every person has a tendency to speed while they are driving. But most people still drive slowly because nobody wants to get a speeding ticket. But now, during the development of technology, people invented something called the radar detector, which can avoid you from getting caught while you are driving over speed. In this paper, I want to talk about the Passport 8500 X50 comparing to the Valentine One and Bel 985, which is known as the world’s best radar detector. Before trying to discuss this detector; it is important to know either the history of the radar detector or the difference of the police signals. Escort, the name of the organization that manufactures different varieties of radar detectors, developed passport 8500 X50. They have also developed Solo S2 (the best wireless radar detector) and Passport 7500 (cheaper, but has lower quality than Passport 8500). The use of radar detectors is prohibited only in Washington DC and Virginia. Any other states in the United States accept the use of radar detectors. This company has maintained its existence in the radar business for about 25 years. At first time, radar was used to tell a driver when construction was in the way of the driver so the driver could drive carefully. But nowadays, many road constructions don’t give off the signal to the radar detector and the driver uses the radar detector not to avoid the construction but to avoid the police. There are many different types of signals in this world, but only three signals that police use to detect speed. There are X, K, and Ka bands. The first signal that police used was the X band. It was used until the mid-1970s. Police of Ohio and New Jersey invested a lot of money in X band radar so even now; most police in those states still use this band. The second band is K band which was invented in 1976. Its frequency is twice as long as the X band. It means the accuracy is better in K band. The last band is Ka band. It has a better frequency than all other bands. Nowadays, the use of Ka band is relatively high. Most police use this band to catch people speeding. Passport 8500 X50 operates at X band in a frequency 10.525 GHz  ± 25 MHz, at K band in a frequency 24.
