Handheld radios will be used as the primary communication device. Each radio will be fully charged prior to the event, and set to channel 1.

The radio is the most interesting because it has changed the way entertainment works. The inventor of the radio is still unknown however there are many great people that contributed to the creation of the radio. Heinrich Hertz, a German scientist has proven that radio waves occur in nature. In 1896 Guglielmo Marconi had sent a Morse code radio signal and had also received it. This was the spark of the radio. He had applied for a patent in wireless telegraphy and was granted.

2) In 1919 the very first radio station was invented. The radio was a form of entertainment, advertisement.

It provides the hardware means of sending and receiving data on a carrier, including defining cables, cards and physical aspects.

4. Radio: most common form of wireless transmission, typical of home routers and most wireless devices to use this form. Infared uses low frequency light waves to carry data using line-of-sight.

On old radios the antenna was detrimental to the radio’s operation. Today, the antenna is not necessary. AM radio does not have as good of quality as FM but it can travel farther distances. FM signals can be interfered by things such as mountains or other barrier

The Radio was introduced to society because of the telegraph and the telephone. These inventions don’t do the same things but their similar branch of technology. “Radio technology began as “wireless telegraphy”. “It all started with the discovery of radio waves, electromagnetic waves that have the capacity to transmit music, speech, pictures and other data invisibly through air.” [Bellis] Majority of technology uses electromagnetic waves to send data information or TV broadcasts. During the 1860’s, Scottish physicist, James Clerk Maxwell predicted the existence of radio waves; and in 1886, German physicist, Heinrich Rudolph Hertz showed how fast the variation of electric current could be placed into space in the form of

More specifically, a sensor is "a device that responds to phenomena, such as light, pressure, or heat, and generates a signal that can be measured or interpreted" [16]. The sensor network community often defines a sensor node as a wireless device which is small, capable of responding to one or several stimuli, processing the data and transmitting the information over a short distance using a radio link. Sensor nodes contain electronic circuits for minimizing power consumption [17]. Sensors are for measuring sound, light and temperature that is typically thought. However, sensors can measure other variables, such as vibrations or electromagnetic fields [18]. Sensor transmits values wirelessly to one or several BSs

For entertainment purposes, the radio station is the pinical of inventions. This would allow for anyone to tune in and listen to music, news and talk shows. The radio was the main way for information to be transford from a news station to the home next to newpapers. This would soon become outdated with a new kind

The best feature of this instrument is that it was capable of taking images in four different spectral positions and the rotating polarizer was capable of measuring magnetic fields.

The equation for radiation resistance is given in (1). As can be seen, the greater the radiation resistance, the more energy is radiated or received by the antenna. When the radiation resistance of the antenna matches the resistance of the transmitter or receiver, the system is optimized. Antennas also have ohmic or loss resistance which decreases efficiency. It can be shown that an efficient antenna must be comparable to a wavelength in size.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

The radio changed the communication technology it was the first technology people could use wirelessly without having to use wires. The radio was invented by Guglielmo Marconi in the early 1890’s. Heinrich Hertz experimented the different frequencies or waves that made the radio possible in the early 1910’s. The radio transmitter from radio stations were used to send radio waves out to give radio’s signal. The radio became really popular in the early 1920’s where people could listen to the news, talk shows, music, etc. After World War l, the radio was a form of entertainment people can listen to in their homes and driving in their cars. By the end of the 1930’s 80% percent of the U.S population had a radio. When People got far away from the radio signal they were listening to they had to tune into another station. Radio is still very popular today and has modernized. Today people still use traditional style of radio, there is satellite radio that has a monthly fee that people can listen to what they want, and people can also listen to the radio on the internet.

An antenna is a system of similar antennas oriented similarly to get greater directivity in a desired direction.

operation but also needs to have an appropriate proposed design. It employs two techniques to improve the radiation pattern. These techniques are the use of an angled dipole and vertical copper plates arranged on the ground plane for improvement in the radiation pattern of lower and upper bands, respectively radiation profile in both bands, namely similar gain, wide beamwidth. One of the popular techniques for broadening the patch antenna bandwidth is to incorporate a U-slot on its surface. They have the ability to confine the power in certain directions instead of scattering the power everywhere.
