Wireless
communications is a huge field, encompassing everything from
radio and television broadcasting through pagers, mobile phones,
and satellite communications. One of the expanding parts of
the wireless world is in wireless local area networks (WLANs).
Driven by widespread acceptance of the IEEE 802.11 standard,
wireless local networking for computers and other devices
is spreading rapidly.
Why Wireless Link?
Every business today needs an Internet connection. For a very
small business, a dial-up modem link may be appropriate, but
as the network becomes a mission-critical tool for communicating
with suppliers and customers, many businesses soon outgrow
the bandwidth of a dial-up link, and need something faster.
An E-1(2Mbps) link has long been the logical upgrade, but
E-1 links are expensive, especially for a business located
outside the metropolitan areas. The wireless system now provides
an alternative which is efficient as well as cost effective.
The wireless link implemented by the Brain Ltd is 100% reliable
and cost efficient. No competitor within Pakistan is yet able
to provide this type of solution.
Main
features of our wireless equipment are given below:
General
Features:
•
Interconnects heterogeneous sets of networks and application
hosts.
• Highly recommended for interconnecting offices with
in a metropolitan area.
• Allows installation of wireless, high-speed intranets.
• Bandwidth up to 11Mbps over RF link.
• Auto recovery within 1 min after a restart.
• CIR for a given bandwidth.
• Fair network availability under heavy loads.
• Operational temperature range –35 ?C to +65
?C.
• Routing support for all standard protocols.
• Highly efficient air time utilization.
• Uses spread spectrum technology for better RF performance.
• Uses different diversity techniques to avoid interferences
from outside world.
• Dynamically adapts to the environment by shifting
its operating channel to that portion of the band currently
free from interference.
Type
of Product / Services:
•
Wideband Internet
? Wireless link can be installed on your site to provide wideband
internet access ranging anywhere between 64Kbps – 11Mbps
[CIR].
• Interconnectivity
? Brain can deploy wireless link to provide interconnectivity
between your offices. A wireless link deployed at your site
connects you to our core fiber optic network through which
you can also interconnect to branch offices located within
reach of our core network.
Who
does Wireless appeal to?
Wireless
link solution is most appropriate for large enterprise organizations
located at remote sites where deploying wired network is both
costly and time consuming. Organizations that require a medium
that can carry wideband traffic can have a wireless link installed
at their site that is able to carry the required bandwidth
from Brain to their office. Wireless link is most suited at
locations where other reliable wired networks are not available.
What
are the benefits?
Wireless
broadband technology wields several advantages over wired
solutions. It is less expensive to deploy. It can be implemented
much more quickly and, arguably, more efficiently. It can
be configured for multiple applications. It is the source
of cheap, high-quality and high-bandwidth services. For many,
it is frequently becoming the source of choice. By deploying
a Brain’s wireless link at your site, it connects your
office to our core fiber optic network which enables us to
join your branch offices if they are located within reach
of our network. You can use our network for interconnectivity
of your branch offices as well as only for carrying internet
bandwidth.
Why
“Brain” for Wireless Services:
The
wireless link deployed by Brain incorporates many advantages.
Our wireless link is best suited for your highly regarded
organization. Some of the features associated with the deployment
of our wireless link are as follows:
•
Our Wireless transceiver system employs Direct Sequence Spread
Spectrum (DSSS) modulation, signal exploiting this method
can actually operate in regions with a negative SNR. Hopper
Plus transmissions are therefore detectable underneath ambient
noise levels - conventional radio scanners cannot intercept
them.
• 16 bits of scrambling can also be layered onto the
data stream; this permits over 65,000 unique scrambling codes.
• It can also be configured to be either open or closed
system - a further level of security. In a closed system,
remote units will never accept Ethernet packets from another
remote and pass them to their network segment.
• The wireless equipment has IP Address Filtering capabilities.
Only packets that contain destination IP addresses meant for
a specific network segment will transmitted by the bridge
to that segment - otherwise the packets are discarded.
• We provide customized point-to-point / point-to-multipoint
broadband connectivity according to the customer requirements.
