The capacity of 802.11(a,b, or g) systems is limited by two main factors; 1) The capacity of the DHCP Server and router and 2) the available bandwidth of the radio interface.\n\nThe typical residential wireless router has a built-in DHCP server to automatically assign wireless (and wired) users an IP address.  Residential DHCP servers usually max out at 256 users.  Enterprise wireless networks use dedicated DHCP servers capable of handling 1000s of users.\n\nThe next limitation is the radio link.  As you know, 802.11g supports link rates up to 54 Mbs.  54 Mbs is achievable only under the best conditions, meaning no other access points or users on the same channel in the area to generate noise.  \n\nAs users are added, the maximum rate available to each user is lowered accordingly, until the number of users are generating more noise than usable signal and effectively jam the access point.\n\nAnother factor in radio capacity is called Near-Far affect.  This occurs when one user has acquired service at a great distance with no interference.  Then a second user, located much nearer to the access point, acquires service and the Near users strong signal over powers the Far users weak signal, effectively jamming the Far users and reducing the access point capacity.

The term wireless networking refers to technology that enables two or more computers to communicate using standard network protocols, but without network cabling. Strictly speaking, any technology that does this could be called wireless networking. The current buzzword however generally refers to wireless LANs. This technology, fuelled by the emergence of cross-vendor industry standards such as IEEE 802.11, has produced a number of affordable wireless solutions that are growing in popularity with business and schools as well as sophisticated applications where network wiring is impossible, such as in warehousing or point-of-sale handheld equipment. \n\nFor futher Info , Click:

The WiFi band is broken down as follows:\n802.11a = 5Ghz\n802.11b = 2.4Ghz\n802.11g = 2.4Ghz\n\nUnfortunatelly b & g can get serious interference from microwaves, cordless phones, Bluetooth, and other equipment using the same 2.4 GHz.\n\nIn b & g there are 14 overlaping channels or bands.  the best ones to pick are 1 and 11.  Note that they do overlap, and the channels only represent the "center" of the frequency range.  The channels are 5Mhz appart.\n\nThe most interference you will get in a building is power, microwave and cordless phones.\n\nWiFi has been demonstrated to work 150+ miles without interference on a flat surface.\n\nI included a few links for further education.

yes, WIFI is a generic name given to wireless networking, it stands for Wireless fidelity.. if you are using it for internet access, it doesnt matter if you have b or d, because unless your internet provider is pushing more then 11 megs you will never notice the difference.

Many organizations utilize wireless local area networks (WLAN) because of their convenience. The trade-off made is convenience for speed. Today’s most advanced wireless standard, IEEE 802.11g, operates at roughly half the speed of the most common 100 Mbit/s wired LAN. The Institute of Electrical and Electronics Engineers (IEEE) began to address this speed differential in the middle of 2003. Their vision was IEEE 802.11n, which would provide speeds equal to or greater than 100 Mbit/s LANs. Their work has yet to be completed. The lack of approval has led some to release so-called Pre-N equipment, which seeks to give the benefits of the 802.11n standard without an official standard. Because there is no official standard, implementing these products has future implications to customers.\n\n\nStandards\n\nStandards are made for very specific reasons. Foremost, they ensure that devices can operate with devices made by other manufacturers. Essentially, when a company releases a product before the ratification of the standard, they must infer what the IEEE is going to set. These inferences mean that the product may be incompatible with the final standard. If this does occur, an organization may be locked in to purchasing only identical hardware to that which they own. This would ensure compatibility.\n\n\nImplications\n\nAnother possibility if incompatibility exists is the release of an upgrade. The company would not be required to release updates, but if it did, there would be considerable work for the support groups. This may include individually upgrading each device, a very time consuming proposition. Despite the time commitment, an upgrade would be the most responsible course of action for the company because the customers would be able to choose any 802.11n solution for their purposes.\n\n\nImplementation\n\nIf an organization chooses to implement the Pre-N technology, the theory is the same as previous wireless network implementations. The setup would most likely begin with a router. This would be hard-wired to the Internet connection. There are also wired ports on the rear of the router. These allow any wired device to be included on the network. The router would then provide access to any device in its range with a compatible network interface card (NIC.) Currently, NICs exist for both desktop computers and notebook computers.\n\n\nAdvantages/Conclusions\n\nThe advantages to using this technology are clear. It will allow computers to connect easily to wireless networks, without sacrificing the speed possible with a wired connection. Another concern that comes up is that gigabit Ethernet is also available. If an organization were to implement this, 802.11n would again be just one-tenth of the speed. The implementation of any wireless network must be carefully considered. Regardless of which standard is followed, the security threats are common. Data is still being broadcast over radio frequencies. Before deciding whether to use Pre-N technology, one must first decide whether wireless is appropriate for their application. Only then should 802.11n be considered.

802.11n is a newer standard of WiFi LAN, or wireless local area network technology, subsequent to standards 802.11a, 802.11b and 802.11g. Its proper name is IEEE 802.11n, as it is a protocol developed by the international non-profit Institute of Electrical and Electronics Engineers. The number “11” indicates the IEEE working group assigned to 802 standards, and the “n” refers to a special task group within this body, known as TGn.\n\nThe IEEE 802.11n standard is scheduled to be reviewed by TGn in November 2005 and should debut in the marketplace sometime in mid-2006. It will reportedly offer quadruple the data transfer rates of the current fastest WiFi technology. It will also operate on the 2.4 gigahertz (GHz) band, like 802.11b and 802.11g. This frequency does not require line-of-sight availability like 802.11a, which works in the regulated 5 GHz band. \n\nTo get an actual idea of the speeds expected in megabits per second (mbps), see the table below which compares the different 802.11 standards:\n\n802.11b 2.4 GHz 5-11 mbps \n802.11g 2.4 GHz 25-54 mbps \n802.11a 5.0 GHz 25-54 mbps \n802.11n 2.4 GHz 100-200+ mbps \n\nIEEE expects a smooth transition to the 802.11n standard with backwards compatibility built into new equipment, allowing consumers and businesses to upgrade network equipment gradually. The faster speeds will allow more robust applications to be effectively run over public hotspots and private LANs, and greater range is also projected.\n\nLike previous advanced WiFi standards, 802.11n will utilize multiple receivers and transmitters, a technology known as MIMO (multiple-input multiple-output). This allows parallel streams of data transmissions, or spatial multiplexing. The 802.11n standard will also incorporate OFDM, or orthogonal frequency-division multiplexing. OFDM splits signal frequencies up into several modulated channels for increased throughput. Aside from private and commercial LANs, 802.11n is expected to support an array of personal electronics including handheld devices. \n\nIf you are considering installing a wireless network in the near future, you might be interested in following the progress of 802.11n to see when it will hit the market. If so, you can track its status at the IEEE website.
