An antenna is a component which directs the movement of radio active waves; the antenna directs the incoming and outgoing of the radio active waves. It is usually made up of metal; it is available in many shapes and sizes. The antenna is used for broadcasting of radio and television. An antenna uses the parabolic reflectors to focus the signals of ...
Amplifier is an electronic device using transistors or electron tubes. This is used to produce and amplification of an electrical signal. It also increases and restores the strength of the signals passing through it. It involves the controlled conduction of electrons especially in a gas or vacuum or semiconductor. An amplifier uses a small amount o...
Directional antenna is an electronic device used to transmit and receive radio signals. This antenna radiates greater power in one or more directions allowing for increased performance on transmit and receive and reduced interference from unwanted sources. Mainly there are two types of antennas indoor and outdoor antennas. The indoor antennas have ...
The omni directional antenna is an antenna system that radiates power uniformly in all directions. The only 3 dimensional omni directional antenna is the isotropic antenna, a hypothetical construct derived from actual antenna radiation patterns and used as a suggestion for specifying antenna gain and radio system effective radiated power. Practical...
It is an electronic device used to transmit and receive radio signals. A directional antenna is an antenna that radiates greater power in one or more directions. This allows increased performances on transmit and receive and receive and reduced interference from unwanted sources. All the antennas are slightly directional. The normal antennas have a...
The function of antennas at base stations of cellular radio systems has been proven to be a successful way to increase the performance and the channel ability of personal communication systems. In compare to those technically highly developed base station antennas, the exterior and the practical principle of car antennas with omni directional patte...
A cell phone is an electronic device that is portable for talking over long distances. Cell phone connects to the cellular network of the site of cell which is further connected to the telephone network of public. Mobile phone offers many services other then acting as a phone. It offer the services like SMS, access to internet and also the MMS faci...
The term grounding means a common return path in electrical circuits. Electricity grounding is nothing but the connection of part of an electrical circuit to an electrical ground. There are three types of grounds, static, RF and electrical. Static grounding is the most difficult. There will no be guaranteed results. The electrical grounding is t...
Booster is a device used for increasing power or effectiveness. It is an enthusiastic promoter. A booster is also called as a radio frequency amplifier. It helps to maintain or increase a protective immune response. Boosters are used in all the electronic devices. They turn the performance of the device to a high position. They significantly inc...
There are many indoor concrete buildings with no windows within 35 feet of the cellular phone units. Criteria for these new locations include low or unsound signal without the antenna booster installed. Tests conducted for indoor functionality of the antenna booster spanned over a period of time of no less than a couple of months. The rationale for...
