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. |
