Public Access Wireless LAN's are arguably the most important commercial use of WLAN's today. Modern wireless Internet access is actually quite fast, and is comparable to DSL, ISDN, or cable. There are four different standards currently in widespread use: 802.11a, 802.11b, 802.11g and 802.11n. The majority of sites use 802.11g or b; it's the least expensive. The slowest with a maximum theoretical speed of 11 Mbps is the 802.11b; 802.11a was developed at around the same time as 802.11b, but it has less range. The 802.11g is the "now accepted " standard that combines the best of both 802.11a and 802.11b. It's got a maximum theoretical speed of 54 Mbps, and is backwards compatible with 802.11b. The 802.11n completely redefines Wi-Fi speed, offering a whole new level of network performance. If you combine 802.11n client and router you will find a wireless experience that outpaces all previous wireless Standards. It's theoretical throughput clocks in at 160 Mbps or seven times faster than 802.11g networks. The key to this speed is MIMO (multiple input/multiple output) which uses multiple antennas (2 to 3) to send and receive digital data in multiple simultaneous radio streams, in turn multiplying total performance. The only caution to bear in mind is; you can share data, photos and music among multiple devices greater distances or better speeds than ever before. The following system fit into the category of wireless:

• Bluetooth
• RFID (Radio Frequency Identification)
• PDA (Personal Digital Assistant)
• Smart Phones (Palm Pilot, iPAQ, Blackberry etc.)

Small and medium Site Owners

Business owners are introducing WLAN access services to attract customers and to increase customer retention at their location.  They may also be introducing WLAN access as a revenue generating service. The wireless access service is not the "core" revenue source of the business; therefore, they tend to utilize Avant Garde to provide technical expertise, Installation, customer support and the billing mechanism for the Wireless access.  With our wireless system, business owners have the option of charging customers for this additional service.


Travelers' Wireless Internet Access (hotels, airports, train stations etc.)

These days there are many Wireless Internet access options available for travelers. It is not uncommon for airports and coffee shops to offer Wireless Internet connections (some on a pay-per-usage basis, but most are limited free time). It is now also now quite common for hotels and motels to offer Wireless Internet connectivity (usually on a pay-per-diem basis or free to registered guests). Libraries and parks are getting in the act by offering Wireless Internet access, and usually for free under a limit access rules. Internet access for the road warrior is easier now than it has ever been, some hotel guests will forgo a hotel with a good rate but with no internet access and opt for one with a higher rate and internet access. Hotel guests are making reservations based on this criteria. Today's traveler is more demanding than ever, they expect to have internet access and it is up to the businesses to provide these services.
