Radio point-to-point is a technology where the connection is established between two nodes or communication endpoints. You can take the example of a telephone where one telephone is connected with the other telephone. There 1:1 conversation is possible. This is just the opposite of point to multipoint communication or broadcast connection. In broadcast connection information from one node can be collected by many nodes.
Some Examples of Radio Point-to-Point
Below are some of the examples where radio point-to-point technology is involved
- Leased line
- Microwave Radio Relay
- Two-way Radio
This technology of point-to-point refers to wired connection when it is about computer networking or computer architecture. Radio point-to-point is unique in nature as only one communication device can be connected in this technology, unlike bus bar technology where multiple devices can be connected.
Radio point-to-point is also abbreviated as P2P, but while using P2P it is different from actual P2P which means peer-to-peer with reference to file-sharing network.
Work systems are not by any means the only method to comprehend low power system requirements for IoT applications. Truth be told, a greater part of low power, wide-territory arrange (LPWAN) innovations, notwithstanding WiFi and cell systems, utilize a star organize topology. A star system has a switch or passage in the center that interfaces with every one of the terminals or hubs.
The benefit of star topology is that all the intricacy in the system is headed to a focal hub, so the various hubs just need to convey in their time or recurrence opening. How they convey relies upon whether remote multiplexing is done through recurrence division various access (FDMA), time-division numerous entrance (TMA), or code-division different access (CDMA).
The essential impediment of star topology is that the radio connection between the portal and the end hub or terminal can be extremely long, which means the further a hub is away from the door, the more vitality it needs to consume handing-off a message. In any case, dissimilar to a work hub that must be always “alert,” star hubs can rest between message transmissions, helping ration the aggregate sum of vitality used by every hub.
Radio Point-to-Point – Basic things you need to know
Here links between data take place within two points only and there will not be any data or packet formatting. The computers on both ends will be responsible for the formatting of data between them. RS-232 was generally involved as an interface or communication medium between two computers. The computers that are close to each other may be directly connected through the interface cards installed in them and a wire.
A modem is required to connect two endpoints if the computers are placed far away from each other. In those types of cases, the endpoints will be connected with the modem. The analog telecommunication signal is converted into a digital signal in this process. It is also termed as a dedicated leased or private line when used by a telecommunication operator. The ARPANET (it was an early packet switching network that used TCP/IP protocol) used to provide radio point-to-point known as interface message processors.
Modern Radio Point-to-Point links
If talking about modern point-to-point links it has been transformed into wireless connections from a wired connection between two nodes or between two endpoints. TDMA (Time Division Multiple Access) technologies are involved in modern radio point to point links and are bi-directional in nature. The example of modern radio point-to-point is microwave relay link.
Microwave antennas are parabolic in shapes and are connected by each other by means of transmitters that transmits narrow beam of microwaves and the receiver at the other microwave antenna receives the signal transmitted by the other antenna. The thing which you have to keep in mind is that there must be clear LOS (Line of site) between the two microwave antennas.
Another example of radio point-to-point link is laser. There transmission of data takes place on a light beam. Like microwave antennas in case of lasers, a clear line of sight is required. Here the permissible range between the two points is approximately 40 miles.
I hope this blog is information-rich that gives you a clear understanding of what radio point-to-point is and which are the devices that use radio point-to-point.
