Infrared is a wireless mobile technology used for device communication over short ranges using infrared light (just beyond visible light). With infrared, computers can transfer files and other digital data. 
The infrared transmission technology used in computers is similar to that used in remote controls. Infrared can be used for purposes other than remotes.
Infrared is used in a variety of wireless communications, monitoring, and control applications. Here are some examples:
  • Home-entertainment remote-control boxes
  • Wireless (local area networks)
  • Links between notebook computers and desktop computers
  • Motion detectors
  • Fire sensors
  • Night-vision systems
Infrared technology is designed for data transmission over very short distances. For example, two computers with infrared transceivers can communicate wireless as long as they have a short line-of-sight connection, generally within one meter.
Infrared supporting data rates up to 4Megabits per second and the maximum range is 100m.
Benefits of infrared is that it uses very little power, the cost of using infrared is minimal and it tends to be reliable.
Disadvantages of infrared is that the transmitters and receivers must be closely aligned to communicate by being directly in sight of each other.

Microwaves are high-frequency signals in the 300 MHz to 300 GHz range. The signals can carry thousands of channels at the same time, making it a very versatile communication system. Microwaves are often used for point-to-point telecommunications, which means that the signal is focused into a narrow beam. You can typically recognise microwave-based communication systems by their use of a large antenna, often in a dish format. This is in contrast to radio signals, which are typically broadcast in all directions. Radio signals operate in the 3 Hz to 300 MHz range.

Microwave signals are used for both satellite and ground-based communications. Many TV and telephone communications in the world are transmitted over long distances using microwave signals. They use a collection of ground stations and communication satellites. Ground stations are typically placed roughly 50 kilometres apart so they 'see' each other.

The maximum data transfer rate is 300gbps
The maximum range of the microwaves is 100m.
An advantage of microwave transmission is that rather than using cables or other physical wires, it uses electromagnetic waves with small wavelengths. The size of the wavelengths allows a transmitter to direct microwaves to a receiver in a narrow beam, improving efficiency.

The orbiting satellite transmits (and receives) its information to a location on Earth called the Network Operations Center or NOC (pronounced "knock"). The NOC itself is connected to the Internet (or private network), so all communication made from a satellite dish to the orbiting satellite will flow through the NOC before it reached the Internet.  
Cost Effectiveness - Cost of satellite capacity does not increase with the number of users/receive sites, or with the distance between communication points. Whether crossing continents or staying local, satellite connection cost is distance insensitive.]]> 2016-10-31 10:54:56 UTC https://padlet.com/James_Gould/26bkuzbj9a3q/wish/134171241 limitations its vey exspesive 286907 https://padlet.com/James_Gould/26bkuzbj9a3q/wish/134175470 2016-10-31 11:22:55 UTC https://padlet.com/James_Gould/26bkuzbj9a3q/wish/134175470
