What is Wi-Fi ,[object Object],[object Object]

Standards ,[object Object],International standard for wireless networking that operates in the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a throughput of up to 11 Mbps with a range of just over 300 feet indoors. This is a very commonly used frequency. Microwave ovens, cordless phones, medical and scientific equipment, as well as Bluetooth devices, all work within the 2.4 GHz frequency band.

Standards ,[object Object],802.11b enables transfers of up to 11 Mbps. Comparable to 10BaseT in speeds, 802.11b is the most common wireless standard deployed today. In comparison T1 speeds are 1.54Mbps and DSL is normally in the 640Kbps range. Most deployments of Wireless utilize 802.11b

Standards ,[object Object],International standard for wireless networking that operates in the 5 GHz frequency range (5.725 GHz to 5.850 GHz) with a maximum 54 Mbps data transfer rate. The 5 GHz frequency band is not as crowded as the 2.4 GHz frequency, because the 802.11a specification offers more radio channels than the 802.11b. These additional channels can help avoid radio and microwave interference. Cost of 802.11a equipment is approximately twice that of 802.11b and current deployment is limited.

Wireline Other Comparable Technologies If you have a network installed today, wireline is what you. Does it satisfy your needs? There is not reason to abandon your current infrastructure for wireless if wireline currently serves all your needs. If it serves some, but not all of your needs, Wireless may be a good supplement.

HPNA Other Comparable Technologies HPNA is Phone Line Networking. HPNA allows you to transmit data over normal phone lines at the same time you use that phone for voice calls and DSL. HPNA v2.0 runs at 10Mbps over a standard phone line. V3.0 is coming soon and delivers 100Mbps. If you currently have a lot of phone lines running through your facility this may be an option to consider.

Bluetooth – 802.15 Other Comparable Technologies Bluetooth is the standard for wireless personal area networks or WPAN. It allows high speed transmission of data over very short distances. Bluetooth is normally used for transferring data between laptops, or in Internet Kiosk type applications where roaming is not needed.
