In the field of telecommunication or you can say wireless telecommunication Point to Multipoint wireless technology is also popularly termed as PTMP or PMP or P2MP. Here you can obtain many connections from one single connection. Hence you will obtain multiple paths from one single location.
In Point to Multipoint Point wireless technology there is a central antenna or an array of antenna that broadcasts to many other receiving antennas. This system mainly uses FDMA or TDMA that allows bidirectional flow of traffic. FDMA is generally known as Frequency Division Multiplexing and TDMA is known as Time Division Multiplexing.
In Point to Point or most popularly known as P2P refers to a mode of communication in which there is a connections in between two points or nodes or more specifically there is a connection between two end points. Like PTMP, here in P2P also two endpoints communicate by the process of FDMA or TDMA that allows traffic to flow in a bidirectional path. High gain Directional antennas are used here if the link type is fixed. For this reason long distance and high capacity links are obtained.
Practical Example of Point to Multipoint Wireless technology
You will find a cable free Point to Multipoint Base Station consisting of a Quad Radio base station along with antennas present in four sectors. This type of setup you will find in mobile network towers. This is nothing but a major hub for wireless broadband services. And this setup is an example of Point To Multipoint or P2MP wireless technology.
Some of the Devices where Point to Multipoint and Point to Point Wireless Technology
-
It is used in Radio Communications
Some of the commercial products with frequency ranging from 450MHz to 6GHz are available using both Point to Point and Point to Multipoint Wireless technologies. They both have integrated or external antennas.
-
It is also used in Cable Free P2MP Radio
Omni directional Antennas with four radio interfaces are present if short coverage is required also for greater coverage directional integrated antennas are used.
-
Used in Microwave Communication
Generally the technology behind microwave communication is Point to Point. There are only few companies that offers Point to Multipoint wireless technology for microwave communication. A cable free microwave antenna is parabolic in shape and can offer a speed up to 880Mbps or more.
-
Point to Multipoint Wireless technology is used in Millimetre Wave
Millimetre Wave is also known as MMW. Its frequency ranges from 58 to 90GHz. Some Point to Multipoint Wireless technology products at a frequency of 60GHz is also available.
-
Used in Free Space Optics
Radio Point to Point Technology is used in Free Space Optics due to narrow beamwidths and limited link margins. Cable less FSO unit is used for PTP or Point to Point Connection. An integrated optics is present in free space optics with no separate antenna. It has a capacity of around 0.5 degrees which you can say is a narrow bandwidth. Its capacity can extend up to 1.5Gbps.
