While Because In fact, Due to its higher cost, This higher frequency compared to The higher frequency also means Some vendors offer hybrid IEEE expanded on the original Vendors often prefer using these frequencies to lower their production costs. Being unregulated, However, by installing Aside from these five general-purpose Wi-Fi standards, several other related wireless network technologies offer slightly different value propositions.
The following IEEE Additional standards that are not mentioned here may also exist. However, they may have been supplanted or canceled and are not relevant to the information in this article. Actively scan device characteristics for identification.

This specification is not backwardly compatible with This standard was ratified in This extension provides for improved encryption methods and for the integration of the IEEE Uses multiple transmitter and receiver antennas also known as multiple-input and multiple-output, or MIMO to allow for increased data throughput and range. Pre-standard hardware is commercially available and not compatible with PittNet Wi-Fi.
The operating mode for wireless networks in which each end-user device is configured to associate with a wireless network access point through which network services are accessed. The operating mode for wireless service in which end-user devices interact with each other in a "peer-to-peer" configuration. Ad hoc mode does not require the use of a wireless network access point. Prior to the installation of any wireless devices, Pitt IT will review the usage requirements for the area in question to determine the optimum number of wireless access points needed to efficiently support all users in the area simultaneously.
Space configuration, construction materials, anticipated number of end-user devices to be served, and potential sources of radio frequency interference will be taken into consideration when conducting a site survey. Pitt IT will provide support for infrastructure mode installations only. These installations require at least one wireless access point. Ad hoc wireless mode will not be supported. In order to prevent problems caused by radio interference, to ensure the integrity of University resources, and to ensure the widest availability of reliable wireless networking services, the University shall remain the sole owner of all unlicensed spectrums of radio frequencies available for use on any of its campuses and related properties.
The maximum network bandwidth available through a single wireless access point under the A standard wired network port provides switched Mbps dedicated bandwidth. On a wired network, throughput per user is higher because direct bandwidth competition is eliminated for users of switched ports and a dedicated Mbps is allotted for each user.
Because wireless network access users share the available bandwidth, network performance can be diminished as additional wireless users connect to the access point. Bandwidth intensive applications will diminish the available shared bandwidth for all users in the coverage area. Actual throughput within wireless coverage areas will vary depending on the number of users and the types of applications being used on client computers.
Client computers using As such, Pitt IT recommends that client adapters support Wireless network installations work well for low-bandwidth activities, such as web browsing and email. High-bandwidth activities, including streaming video, MP3 sharing, and videoconferencing are likely to result in reduced performance and should be discouraged by University units until industry standards and equipment become available to support these activities.
Current wireless network technology effectively permits from users to utilize a single wireless access point effectively despite vendor claims that much larger numbers of users can associate with a single wireless access point. See the Bandwidth Usage Guideline section for additional details. Integration of wireless network access points or other wireless communications equipment to University of Pittsburgh network will only be performed by Pitt IT.
University students, faculty, staff, and units may purchase the Wi-Fi certified wireless network interface adapters of their choice to connect end-user devices to the University's wireless networks. University units will be required to remove any wireless network infrastructure equipment Wi-Fi routers and bridges not installed by Pitt IT. Wireless network access points will be connected to the University's wired network by means of a specially designated wireless port that will be installed specifically for this purpose.
University units and individuals may not disconnect a wireless access point from its associated wireless port or interfere with any components of the wireless AP assembly including antennas, antenna cables, or management cables. Wireless ports are specially configured to supply electrical power to the wireless access point and may cause permanent damage to an improperly connected end-user device.
Wireless network installations at University locations consist of the necessary Wi-Fi certified wireless access point devices. The number of access points required will be determined by initial estimates of demand for users and the size of the area to be covered. If the number of users to be served exceeds the practical number of users that can connect to single access point with sufficient bandwidth available to each user, additional access points may be installed.
In areas with a high density of users, such as classrooms and lecture halls, additional access points will be installed to satisfy the usage requirements. All wireless access point devices will be installed and maintained by Pitt IT. In order to ensure the reliable performance of the University's network, Pitt IT will investigate reports of specific wireless devices that are suspected of causing interference and performance problems in the same manner in which Pitt IT investigates reports of specific devices connected to wired ports that are suspected of causing disruption.
Although Pitt IT will not actively monitor content carried on the University's wireless network radio frequencies when investigating reports of potentially interfering devices, wireless network detection equipment will be used to detect unauthorized wireless network equipment.
Units will be required to remove any such equipment found in unit-controlled University space. Wireless access service is provided based on the anticipated utilization data gathered during initial site surveys conducted by Pitt IT.
As the number of users increases, effective wireless network performance may be diminished. Current industry standards for wireless network service do not provide sufficient throughput to effectively support bandwidth-intensive applications and network services.
Pitt IT will address problems encountered in the use of wireless network services according to the following priority list: public access, academic, research, administrative, and staff use.
Access to the University's wireless networks will require all authorized users in all areas to authenticate to the network using their assigned University Computing Account username and password through the use of University-provided wireless client software or Network access logs will be maintained containing the username, time of access, and duration of use for all users who access the network using wireless connections. The goal is to maintain backward compatibility with Final approval was expected in November There are some products in the home-entertainment and industrial-control spaces that have The goal of this standard is to help It reached draft status in November The group is targeting at least a 4X improvement in throughput compared to Approval is estimated to be in July Also known as Next Generation 60GHz, the goal of this standard is to support a maximum throughput of at least 20Gbps within the 60GHz frequency The standard is expected to be approved between September and November Keith Shaw is a freelance digital journalist who has written about the IT world for more than 20 years.
