Wireless networking is a relatively new concept for most companies & consumers. Like the title says-No wires are used, instead wireless “bridges” or "Access points" are used to connect PC’s together. Also, if required, these can be connected to a traditional wired network (Like in the diagram opposite). The advantages?
- No wires!!-Ideal for busy environments where trailing wires would be a danger.
- Cost effective-If you have a remote site sometimes leased lines are the only alternative-these cost ££ to run! Wireless would pay for itself within months!
- Mobility-Change room layouts without the worry or cost of re-cabling.
- No mess! Avoid unsightly wires and unnecessary drilling!
Wireless networking is also growing in popularity in the home environment. We can install a wireless router and configure your laptop and/or PC's to access your email and access the Internet! Charges start from as little as £180 for this service. This can be performed for ADSL users, ISDN users and even dial-up users! The simplest way to share an Internet connection throughout the home.

What is 802.11a & 802.11b & 802.11g?
802.11a is a WLAN communication standard. 802.11a is one of the wireless Ethernet standards in the 802.11 series.
802.11a wireless networks support a maximum theoretical bandwidth of 54 Mbps. 802.11a's principal advantage over 802.11b, that supports 11 Mbps, is improved performance. However, 802.11a access points (AP's) and adapters also cost significantly more than their 802.11b counterparts.
802.11a transmits radio signals in the frequency
range above 5 GHz. This range is "regulated," meaning that 802.11a
equipment utilises frequencies not used by other commercial wireless products like cordless phones.
In contrast, 802.11b utilises frequencies in the unregulated 2.4 GHz range and encounters much more radio interference from other devices.
Examples: Though it helps improve network performance and reduce interference, the range of an 802.11a signal is limited by use of the high 5 GHz frequency. An 802.11a AP transmitter may cover less than one-fourth the area of a comparable 802.11b AP. Brick walls and other obstructions affect 802.11a wireless networks to a greater degree than they do comparable 802.11b networks.
802.11g
In 2002 and 2003, WLAN products supporting a new standard called 802.11g began to appear on the scene. 802.11g attempts to combine the best of both 802.11a and 802.11b. 802.11g supports bandwidth up to 54 Mbps, and it uses the 2.4 Ghz frequency for greater range. 802.11g is backwards compatible with 802.11b, meaning that 802.11g access points will work with 802.11b wireless network adapters and vice versa.
What About Bluetooth?
Bluetooth is an alternative wireless network technology that followed a different development path than the 802.11 family. Bluetooth supports a very short range (approximately 10 meters) and relatively low bandwidth (1 Mbps). In practice, Bluetooth networks PDAs or cell phones with PCs but does not offer much value for general-purpose WLAN networking. The very low manufacturing cost of Bluetooth appeals to vendors.
The future........
802.11n is an upcoming industry standard for high-speed Wi-Fi networking. 802.11n is designed to replace the 802.11a, 802.11b and 802.11g Wi-Fi standards for local area networking.
Once finalized, 802.11n will support bandwidth greater than 100 Mbps and perhaps even greater than 200 Mbps. Some manufacturers offer "pre-N" wireless equipment based on early drafts of the standard. However, this equipment may turn out to be incompatible with true 802.11n equipment, expected to hit store shelves sometime in 2006.
