A wireless (Wi-Fi) WLAN
is a wire (cable) free local area network, extended on a limited area,
depending upon the equipments that are being used and their power,
which allows data transfer and internet using radio waves.
Eliminating all types of cables, enables a higher
network elasticity/flexibility, which can be configured in an optimum
way by professionals to satisfy the needs of each end-user.
It's good to know that the equipments are not efficient
without being correlated with the professionalism of the installation
and configuration team. This is the reason why so many clients contact
us after being disappointed by the low efficiency of their actual
terrestrial or wireless network, although they installed the latest
generation equipments with high overall costs.
Our team designs internet networks or wireless
distribution networks (Wi-Fi) using strict
measurements based on site-surveys, absolutely independent for each
client or ISP.
We also implement already configured wireless and radio
networks and solutions for corporations with coverages of 3 Km, 5 Km or
20 Km radius, like the iDirect solutions, that have already
implemented the administration interface for 200 end users. These
solutions are generally applicable to large societies, industrial
companies that have large surfaces to cover with direct visibility, and
who need vital mobile communications for their employees. These
solutions are preconfigured for a large, but also a constant number of
users, so they are not applicable for a growing ISP, or an ISP in
transition, or networks having future projects, because there are
For ISP clients, or for networks in transition with a
large surface to cover and a growing number of users, a principal
network is created, which later develops by adding additional
equipments and bridges, the structure being adapted exactly for the
It's good to know that Wireless Fidelity (Wi-Fi)
represents a category of products compatible with WLAN
standards based on IEEE 802.11. The new standards that
preceded 802.11 specifications, like 802.16 (WiMAX),
are part of the actual networks and offer lots of improvements, from
larger coverage areas to higher rates of transfer.
Generally, Wi-Fi networks can lose due to the wrong
conception of the network, improper equipment, too far distances or
natural phenomena (rain, snow, fog). Applicable laws limit the
standards and power of the equipment and in the same time the spectrum
for applicable frequency, reason for conceiving the network with regard to the
parameters imposed by low, represents a great challenge for our
differences between terrestrial networks and a wireless
radio network are multiple, the wireless networks bringing many
- Unlike other radio wave systems or networks, Wi-Fi
uses a radio frequency spectrum that doesn't need a license, so the
user doesn't need approval for utilization.
- It allows the development of a local WLAN network without using any
cables, reducing the necessary costs for the development of the network
and avoiding different obstacles in implementation.
- Wi-fi is a global standard, which means that Wi-Fi clients can work
in different countries.
- Various possibilities to connect the final user, through WLAN plug-in
cards like PCMCIA, PCI, USB or various Wi-Fi systems
like 802.11a or 802.11b or 802.11g integrated in most
of the modern notebooks.
- Alternative or combined possibilities for building the network using
Wi-Fi equipments, unidirectional or bidirectional, sectorial,
directional or omnidirectional Wi-Fi antennas, access points with
different powers and different gains.
The conclusion is that a performant wireless network is
based on high quality equipments and the most important... specialized
technicians in radio transmissions to implement it.
