Standards-Based Technology

The DWL-7100AP Wireless Access Point utilizes the 802.11a, 802.11b and draft 802.11g standard.

The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54Mbps* within the 2.4GHz band. The 802.11a standard also increases the data rate up to 54Mbps, but within the 5GHz band. Both 802.11a and 802.11g utilize OFDM technology.

This means that in most environments, within the specified range of this device, you will be able to transfer large files quickly or even watch a movie in MPEG format over your network without noticeable delays. This technology works by transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the amount of crosstalk (interference) in signal transmissions.

The DWL-7100AP offers the most advanced network security features available today, including WPA.

In addition to its compatibility with 802.11g and 802.11a devices, the DWL-7100AP is backward compatible with 802.11b devices. This means that if you have an existing 802.11b network, or a network with a mixture of 802.11g, 802.11a and 802.11b, the devices in that network will be compatible with the DWL-7100AP.

*“Maximum wireless signal rate derived from IEEE Standard 802.11a and 80211g specifications. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead lower actual data throughput rate.”
