CCTV in Austria plus Public WLAN

The wireless mesh MRX technology (mobile router) allows you to build a large, flexible and robust wireless network based on the IEEE802.11s standard. The special protocol allows the combination of many MRX stations into a meshed (radio) network with redundancy and autonomous pathfinding. The communication and payload traffic within the meshed network is encrypted, and only stations that know the mesh key can join the network and become part of the system.

Any new station that gets within range of the mesh and has the right mesh key installed will automatically be integrated into the system and the possible new paths will be considered for use. When stations disappear from the grid, either due to power failure or too high attenuation, the changed structure of the network is recognized, taken into account and an autonomous realignment is performed. For the preparation of such cases, no alternative routes need to be defined. The network works without external help or interaction - this makes it so robust and flexible.

Each MRX station also serves as a possible entry point into the mesh. Clients can be connected via various interfaces (WiFi access point, Ethernet with and without PoE). Laptops, mobile phones, cameras etc. as well as entire networks can be connected to the meshed system and use the provided (variable, dynamic) infrastructure.

The mesh may have one or more uplinks (WAN ports) to connect to other systems such as the WWW and allow access to the connected clients. Such WAN port may be an integrated mobile uplink (2G, 3G, 4G) or an Ethernet connection to an external modem / router (DSL, Cable, SATCOM).

The MRX can be mounted on walls and masts as well as in vehicles (ground, water, air). Special housings are available for the harshest environmental conditions.

Radio over Mesh

The extension of digital and analog radio (radio) over alternative transmission paths offers many possibilities. So it is possible to bypass existing technical obstacles (supply in underground garages, tunnels, etc.) but also the rapid interconnection of radiotelephone systems in a larger network.

The use of the mobile and robust mesh for extension of the radio coverage helps authorities and industry to improve the structure and increase safety in particular areas.

Object - Monitoring

In addition to many mobile applications of the MRX family, stationary applications are also a progressive trend. With object monitoring, even remote areas can be accessed via the mesh, even if they are several kilometers away. By using cameras, live images as well as voice data can be sent to a reception point integrated in the mesh and evaluated there. With autonomous pathfinding, the mesh always chooses the best connection in the ratio of bandwidth to signal strength. The failure of links is compensated by the redundant system, without the need for external intervention. Clients who know the mesh key can use this infrastructure and join the mesh. The mesh is secured by AES 256 encryption, which makes the meshed system secure against eavesdropping and protects against espionage. The consumption of the individual MRXpoe relay stations is <20W. In addition, the hardware is fanless and maintenance-free.

Monitoring of tunnel systems

The monitoring of tunnel systems can be realised even with tunnel lengths of several kilometres through a "pearl necklace" of MRX stations. By using cameras, live images - which have detected an accident or smoke development, for example - can be sent to a receiving centre via the mesh system.

The failure of lines is compensated by the redundant system without the need for external intervention. Clients that know the mesh key can use this infrastructure and join the mesh. The mesh is secured by AES 256 encryption, which makes the meshed system tap-proof and protects against espionage.

In addition to the standard power supply via an AC power cable, an optional PoE++ supply via a LAN cable is offered. The PoE interfaces of the MRX can supply up to 4x PoE cameras. The supply of PoE+ cameras is also possible here.

The consumption of the individual relay stations is <20W. In addition, the hardware is fanless and maintenance-free.

The monitoring of larger rural areas such as forests, moors or mountain landscapes where no infrastructure is available, but where monitoring via cameras is necessary.

With its high protection class and the equipped hardware and software, the MRX.compact has been designed precisely for these applications.
