A GSM antenna sends and receive information with the many cellular handsets inside the area (cell) assigned to it . . . while a microwave antenna sends and receive information from another single microwave antenna that it it's mate in a point-to-point connection.

Which type of antennas are used at microwave frequency?

A horn antenna or microwave horn is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horns are widely used as antennas at UHF and microwave frequencies, above 300 MHz.

What is GSM antenna function?

GSM is Global System for Mobile communication, and is the most popular standard for mobile phones. GSM Antenna will boost the signal strength in receiving and transmitting.
...
Frequency band.

What is a microwave antenna used for?

Microwave antenna is used for radiating microwave signal into space and receiving microwave signal from space. Microwave antenna acts as a transition region between free space and guiding structure like a transmission line in order to communicate between two or more locations.

Is a satellite dish a microwave antenna?

A microwave antenna includes a satellite dish used for radio, TV or data communications.

Are microwave antennas dangerous?

As previously noted, bare element antennas can burn skin on contact if an active transmitter is connected to them. Microwave dishes and “whip antennas” can create heating of the body, if the intensity of the RF field is sufficient.

What is pyramidal horn antenna?

Pyramidal horn (a, right) – a horn antenna with the horn in the shape of a four-sided pyramid, with a rectangular cross section. They are a common type, used with rectangular waveguides, and radiate linearly polarized radio waves.

Is GSM still used?

In the US, Sprint, Verizon, and US Cellular use CDMA. AT&T and T-Mobile use GSM. Most of the rest of the world uses GSM. The global spread of GSM came about because in 1987, Europe mandated the technology by law, and because GSM comes from an industry consortium.

What is full GSM?

The Global System for Mobile Communications (GSM) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.

What is a GSM number?

The GSM system uses TDMA to split a frequency into time slots. Probably the most useful thing to know about the Global System for Mobile communications (GSM) is that it is an international standard. If you travel in Europe and many other parts of the world, GSM is the only type of cellular service available.

Why do microwave antennas need line of sight LOS communication?

The requirement of a line of sight limits the separation between stations to the visual horizon, about 30 to 50 miles (48 to 80 km). For longer distances, the receiving station could function as a relay, retransmitting the received information to another station along its journey.

How far can microwaves travel in air?

Therefore, on the surface of the Earth, microwave communication links are limited by the visual horizon to about 30–40 miles (48–64 km). Microwaves are absorbed by moisture in the atmosphere, and the attenuation increases with frequency, becoming a significant factor (rain fade) at the high end of the band.

Do cell towers use microwaves?

Cell phones communicate with nearby cell towers mainly through RF waves, a form of energy in the electromagnetic spectrum between FM radio waves and microwaves. Like FM radio waves, microwaves, visible light, and heat, they are forms of non-ionizing radiation.
