Appendix B Frequently Ask Question

Q. What is MIMO?

A:MIMO (multiple-inputmultiple-output), a technique for boosting wireless bandwidth and range by taking advantage of multiplexing. MIMO algorithms in a radio chipset send information out over two or more antennas. The radio signals reflect off objects, creating multiple paths that in conventional radios cause interference and fading. But MIMO uses these paths to carry more information, which is recombined on the receiving side by the MIMO algorithms

Many wireless-LAN vendors expect that some form of MIMO will be the basis of work just starting in the IEEE 802.11n Task Group, which is creating a specification for WLANs having at least 100M bit/sec throughput. MIMO doubles the spectral efficiency compared with that of current WLANs.

Q. Can I run an application from a remote computer over the wireless network?

A. This will depend on whether or not the application is designed to be used over a network. Consult the application’s user guide to determine if it supports operation over a network.

Q. Can I play games with other members of the wireless network?

A. Yes, as long as the game supports multiple plays over a LAN (local area network). Refer to the game’s user guide for more information.

Q. What is the IEEE 802.11g standard?

A. The IEEE 802.11g Wireless LAN standards subcommittee, which is formulating a standard for the industry. The objective is to enable wireless LAN hardware from different manufactures to communicate.

Q. What IEEE 802.11 features are supported?

A. The product supports the following IEEE 802.11 functions:

‧CSMA/CA plus Acknowledge protocol

‧Multi-Channel Roaming

‧Automatic Rate Selection

‧RTS/CTS feature

‧Fragmentation

‧Power Management

Q.What is Roaming?

A.Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single Wireless Network Access Point. Before using the roaming function, the workstation must make sure that it is the same channel number with the Wireless Network Access Point of dedicated coverage area.
