IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of medium access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer communication. The standard and amendments provide the basis for wireless network products using the Wi-Fi brand and are the world's most widely used wireless computer networking standards. IEEE 802.11 is used in most home and office networks to allow laptops, printers, smartphones, and other devices to communicate with each other and access the Internet without connecting wires. IEEE 802.11 is also a basis for vehicle-based communication networks with IEEE 802.11p.
A network switch is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
AirPort is a discontinued line of wireless routers and network cards developed by Apple Inc. using Wi-Fi protocols. In Japan, the line of products was marketed under the brand AirMac due to previous registration by I-O Data.
Wi-Fi is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in home and small office networks to link devices and to provide Internet access with wireless routers and wireless access points in public places such as coffee shops, hotels, libraries, and airports.
The Linksys WRT54G Wi-Fi series is a series of Wi-Fi–capable residential gateways marketed by Linksys, a subsidiary of Cisco, from 2003 until acquired by Belkin in 2013. A residential gateway connects a local area network to a wide area network.
IEEE 802.11n-2009, or 802.11n, is a wireless-networking standard that uses multiple antennas to increase data rates. The Wi-Fi Alliance has also retroactively labelled the technology for the standard as Wi-Fi 4. It standardized support for multiple-input multiple-output (MIMO), frame aggregation, and security improvements, among other features, and can be used in the 2.4 GHz or 5 GHz frequency bands.
High-speed multimedia radio (HSMM) is the implementation of high-speed wireless TCP/IP data networks over amateur radio frequency allocations using commercial off-the-shelf (COTS) hardware such as 802.11 Wi-Fi access points. This is possible because the 802.11 unlicensed frequency bands partially overlap with amateur radio bands and ISM bands in many countries. Only licensed amateur radio operators may legally use amplifiers and high-gain antennas within amateur radio frequencies to increase the power and coverage of an 802.11 signal.
The DG834 series are popular ADSL modem router products from Netgear. The devices can be directly connected to a phone line and establish an ADSL broadband Internet connection to the ISP and share it among several computers via 802.3 Ethernet and 802.11b/g wireless data links.
The current portfolio of PowerConnect switches are now being offered as part of the Dell Networking brand: information on this page is an overview of all current and past PowerConnect switches as per August 2013, but any updates on current portfolio will be detailed on the Dell Networking page.
Netgear's Digital Entertainer line of products are digital media players that can pull multimedia content from home computers to the typical audio/video entertainment center. There are three products in the line, the EVA700, the HD EVA8000 and the current EVA9150 Digital Entertainer Elite. All support high definition video, the EVA700 via component output up to 1080i and the EVA8000/EVA9000 up to 1080p with both component and HDMI connectors. All models support audio, video, image and streaming audio and video formats and can be networked via wired and wireless Ethernet. The EVA700 is Intel Viiv certified.
IEEE 802.11a-1999 or 802.11a was an amendment to the IEEE 802.11 wireless local network specifications that defined requirements for an orthogonal frequency-division multiplexing (OFDM) communication system. It was originally designed to support wireless communication in the unlicensed national information infrastructure (U-NII) bands as regulated in the United States by the Code of Federal Regulations, Title 47, Section 15.407.
IEEE 802.11g-2003 or 802.11g is an amendment to the IEEE 802.11 specification that operates in the 2.4 GHz microwave band. The standard has extended link rate to up to 54 Mbit/s using the same 20 MHz bandwidth as 802.11b uses to achieve 11 Mbit/s. This specification, under the marketing name of Wi‑Fi, has been implemented all over the world. The 802.11g protocol is now Clause 19 of the published IEEE 802.11-2007 standard, and Clause 19 of the published IEEE 802.11-2012 standard.
The AirPort Time Capsule is a wireless router which was sold by Apple Inc., featuring network-attached storage (NAS) and a residential gateway router, and is one of Apple's AirPort products. It is essentially a version of the AirPort Extreme with an internal hard drive. Apple describes it as a "Backup Appliance", designed to work in tandem with the Time Machine backup software utility introduced in Mac OS X 10.5.
Linksys manufactures a series of network routers. Many models are shipped with Linux-based firmware and can run third-party firmware. The first model to support third-party firmware was the very popular Linksys WRT54G series.
The O2 Wireless Box is a wireless residential gateway router distributed by O2. The latest version is based on the 802.11n standard and also supports 802.11g and 802.11b devices. The device connects to the Internet using either an ADSL2+ or ADSL connection.
Hewlett Packard Enterprise Networking is the Networking Products division of Hewlett Packard Enterprise ("HP"). HPE Networking and its predecessor entities have developed and sold networking products since 1979. Currently, it offers networking and switching products for small and medium sized businesses through its wholly owned subsidiary Aruba Networks. Prior to 2015, the entity within HP which offered networking products was called HP Networking.
Ethernet Routing Switch 3500 series and Ethernet Routing Switch 2500 series or ERS 3500 and ERS 2500 in data computer networking terms are stackable routing switches designed and manufactured by Avaya.
Dell Networking is the name for the networking portfolio of Dell. In the first half of 2013, Dell started to rebrand their different existing networking product brands to Dell Networking. Dell Networking is the name for the networking equipment that was known as Dell PowerConnect, as well as the Force10 portfolio.
The Avaya Virtual Services Platform 4000 series are products that, in computer networking terms, are standalone switch/routers designed and manufactured by Avaya for Ethernet-based networks. The VSP 4000 hardware is a derivative of the earlier Ethernet routing switch 4000 series, leveraging certain shared components, but implementing a new, completely different, operating system derived from the virtual service platform 9000 series. The role of the VSP 4000 is to extend fabric-based network virtualization services to smaller, remote locations, thereby creating a single service delivery network.
