Specialist Application Products

 

ViaNET heavy industry WLAN products provide a unique, specialised system with no known direct competition. This system enables high data rate radio link connection capacity and uninterruptible packet data stream from moving vehicles to network infrastructure. Communication links are created and maintained between moving vehicles such as trains, metro cars and trucks. All these vehicles share the need to be connected to wireless communication services such as data transfers of data, audio and video in real time. The ViaNET system is installed and deployed in dedicated network areas. ViaNET Access Points (AP) provide radio coverage for the Mobile Terminals (MT). The Access Points communicate with Mobile Terminals over an IEEE 802.11 b/g radio link. As the Mobile Terminals installed in vehicles or machines move throughout the network shifting from the coverage area of one Access Point to another, the connections from the Mobile Terminal roam between the Access Points. At application layer, users can experience an uninterrupted media stream e.g. video camera application. From application perspective the ViaNET system provides a zero delay handover time, which is created with the system solution.

 

Software and network design

 

ViaNET Mobile Terminals and Access Points are based on HW and SW supporting advanced 802.11 OFDM radios. Products have been designed to support zero delay handover enabling uninterrupted application data stream from/to the vehicles. ViaNET network design is based on a bridged network solution, where the wireless communication solution is a transparent part of the network. For example, end users only need to configure their camera and voice applications and its signal use to meet their needs, while the data transfer is provided with a wireless solution. The ViaNET system has been tested with different customers running CCTV (closed circuit television) and remote control applications on top of the ViaNET system.

 

Deployed with external antennas

 

ViaNET AP and MT radio units are used with external antennas. This is because of the need to support versatile installation and deployment requirements. Heavy-duty industrial antennas are available in Access Point and Mobile Terminal versions.
