Wireless data network
For data exchange between operator's computers (nether the less rugged or simple) and management system must be installed wireless data network. A little bit earlier in the industrial objects (container terminals, logistics centers, warehouses) where used low radio frequency (licensed 450 -470MHz) data communication technology "Narrow band". The main advantage of this system - bigger possible max senders power up to 1W, which means bigger possible covered area. Disadvantage is low speed up to 9,6Kbps. Rising possibilities of computer applications brings need of bigger dataflow between server and clients and it is impossible to do this with narrow band.

In this case companies started to look at higher speed wireless technologies, such as 802.11b, 802.11g, working in non licensed radio frequency range 2.4GHz. The disadvantage of these technologies is lower possible max sender’s power up to 100mW, which means lower covered area by one device. Designing such a network requires having experience in calculation and measuring access points quantity and installation points.

For several years Autepra is a partner of USA company LXE inc. Autepra has a great experience in designing and implementation of wireless networks. LXE has installed networks in more than 160 container terminals all other the world. There are very complicated conditions for WLAN installation on the container terminal: open sea absorbs big quantity of senders radiated energy, containers stored by rows make shields to radio waves. In all LXE projects the wireless network, which has been installed in container terminal, works without any reproach.

LXE 2.4GHz data network benefit is special RF antenna – Spire®. This is omni directional antenna with maximum homogeneous relay characteristic to all the directions.

With a help of competence partner LXE, Autepra makes 2.4GHz data networks design and implementation in industrial objects. We give guarantee to all our projects: if installed wireless network does not cover the area which has been specified in the technical requirements, we add all additional equipment in our own expense.
