Network jargon explained - PTP and PTMP

Technical jargon can be a pain. Often people (particularly the engineers and installers) just expect the client to understand it. Then the client feels like they can't ask what it means and by the end of the conversation, nobody is any further forward.

So here it is, PTP and PTMP networks explained.

PTP - Point To Point:

If you have a situation where you need to get a network connection between two buildings and you can't run a network cable due to the length or terrain, then a PTP link is a great solution.

It consists of two antenna that beam a signal between them, this is encrypted so only those two antenna can interpret the signal. Very quick to setup, relatively low cost and a great solution for many rural setups or large sites.

We've used them to extend a network across a farm, between two parts of a holiday park, to a detached garage/workshop or even between two properties.

Your only real limitation is any obstacles between the two points and also other equipment broadcasting on similar frequencies in the area.

PTMP - Point to Multi Point:

As the name suggests, it is similar to PTP but this time you have one radio antenna that allows several antenna to connect to it. A prime example is on a holiday park where you have one main antenna sending out a signal to 20 static caravans. Each caravan has an antenna on it, each receives a network connection.

Just like the PTP network the connections are encrypted and each point can only connect to the main host antenna, they cannot interconnect.

This is how wireless rural broadband solutions work such as Airband. Again the only real drawback is obsticles in the way of the antenna. Weather can also play a part, particularly in strong winds if antenna fixings are not secure.
