Wifi LANs

A Wireless local area network in your home, home office, or business premises when correctly installed can be an ideal way of allowing multiple users email and Internet access. However, a poorly configured wireless network can potentially be a serious threat to your business data and personal privacy.

In recent surveys around 70% of wireless networks were found to be accessible from outside the premises. With a cable based local area network your data is restricted to the cables, when a WiFi radio signal is carrying your data it doesn’t respect your home or business site’s perimeter boundaries, so must be securely encrypted, using for instance WPA PSK encryption. Otherwise anyone with a wireless enabled computer can quickly find you via your network’s transmitted (SSID) beacon and easily connect to your network.
With earlier encryption systems such as WEP there now exists freely available software that potentially will crack the security key on a busy network in just a few minutes, allowing unauthorised access to an apparently secure network.

Having a poorly configured wireless LAN is realistically a bigger danger than leaving your front door wide open, if an attacker has been accessing the Internet via your connectivity for illegal activity then once they have disappeared the trail ends at your PC or office, something law enforcement is not going to appreciate. If confidential information is removed from your network you or your company could have serious liability issues that far outweigh the costs of rectifying your deficient security.

Infolink Know Wireless Networks

Infolink Electronic Systems specialise in the installation, configuration and commissioning of secure 802.11b/g wireless networks to the highest available infrastructure standards.

Our consultants can advise you of the best way to proceed, from a small home network, allowing you to have the simple flexibility of a laptop computer without the wires, to a distributed, multi building, multi nodal configuration. We can also include directional point to point (inter-building, inter-site) connectivity, access points, repeater nodes, Ethernet bridges, multiple SSID interdepartmental accessibility etc.
We can also advise on network modifications for sites with limited or poor reception and wireless coverage.

Who do we work with?

• Home users in domestic premises.
• Small office / home office (SOHO) businesses or teleworkers.
• Small / Medium (SME) businesses in commercial premises.
• Larger companies and corporations, either at head office or regional locations.

What do we do?

• If you have an existing cable based local area network we can give you a quotation for adding wireless connectivity.
• We can expand connectivity on your exiting wireless network.
• If you have an existing wireless LAN we can give it a few security audit and prepare a report of any hardware, software or security inadequacies found.
• Enhance site wide coverage via radio frequency gain enhancement.

We can enhance your existing network via:

• Network Attached Storage. Wired or wirelessly add extra disk capacity for network users.
  
  
• Network attached FTP Server. Allow external systems access to a wired or wirelessly attached secure private area for the uploading and downloading of files without compromising the security of any individual users PCs.
  
  
• Wireless Printservers. Locate USB and parallel / Centronics printers where you want them to be, not where cables dictate. A wireless printer server is allows the printer to be located anywhere within the wireless network’s WiFi broadcast coverage. Users can share this resource without the need to leave a computer always switched on.
  
  
• Remote IPP Printing. Infolink Electronic Systems can configure your wired or wireless network to allow external, mobile and teleworking users to transmit documents directly over the Internet to a printer.
  Thus you can have an accessible, centralised, high quality or large format specialist printer useable by your entire staff.
  For your users it’s no more technical than printing to a printer on the same desk, it’s ideal for a wide variety of applications. Using this method gives immediate, measurable, cost and time benefits and savings by removing the need to have staff spending time printing incoming documents from email attachments, or having unnecessary application software licenses just for printing purposes.
