Point-to-point wireless link

Multipoint links are almost the same as point-to-point links. The only difference is that there is one receiver to which several transmitters send. Instead of one-to-one, an access point acts as the central receiver. The receiver then sends all the information it receives back to the transmitters. This allows several businesses, for example, to connect their networks to each other.

To connect two sites via Wi-Fi, you need two powerful outdoor Wi-Fi access points with built-in sector antennas. You place them on the roof (or on the facade) at both sites. You connect the access points to the networks behind them with an Ethernet cable.

The access points set up a connection together and act as both transmitter and receiver, so data is sent in both directions. Both access points therefore need to be aligned with each other. You can of course easily shield the signal from third parties with encryption.

To achieve a stable wireless connection, you do need a line of sight between the two sites. There must be no objects between the two access points that could block the view, because that causes too much attenuation. A line of sight (LOS) is therefore a requirement.

You can think of the wireless link as a long, invisible network cable. So it does not matter what kind of data you want to send over it (standard data, VoIP, video and so on). If you want to give certain traffic priority (such as VoIP), you can use Quality of Service or VLANs.

Wireless point-to-point equipment is available from just a few hundred euros. We take care of the alignment, so you have nothing more to worry about.
If you need the link for longer than 6 months, we usually advise buying. If you will not need it after that, you can also rent.

Wireless links are becoming increasingly popular. Thanks to ever cheaper equipment and high reliability, wireless links have become indispensable today. Wireless point-to-point links can reach distances of 220 km.

This is, of course, under perfect conditions.

A wireless link can also be many times faster than an ADSL or cable connection from a telecoms provider, so connections between sites run faster. Especially in very busy locations, a wireless link is often a very good alternative when no 4G connection is available.

RRB Security specialises in wireless solutions. Wireless links are also widely used for CCTV systems, to bridge long distances for cameras or simply because there is no way to connect them by cable.
