Aironet Wireless Communications
Aironet Wireless Communications, Inc. was an American manufacturer of wireless networking equipment. It was started by ex- Marconi Wireless employees in 1986 as Telesystems SLW in Canada, right after the United States Federal Communications Commission opened up the ISM bands for spread spectrum license-free use. Telxon acquired Telesystems SLW in 1992, and Aironet Wireless Communications was spun off from Telxon's RF Division in 1994. Cisco Systems acquired Aironet in 1999 and kept it as a subsidiary for several years. One of its pre-acquisition direct competitors was NCR and its successors (AT&T and Lucent), who sold the WaveLAN wireless networking technology.

Gigabit Ethernet
In computer networking, Gigabit Ethernet (GbE or 1 GigE) is the term applied to transmitting Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T, is defined by the IEEE 802.3ab standard. It came into use in 1999, and has replaced Fast Ethernet in wired local networks due to its considerable speed improvement over Fast Ethernet, as well as its use of cables and equipment that are widely available, economical, and similar to previous standards. The first standard for faster 10 Gigabit Ethernet was approved in 2002. History Ethernet was the result of research conducted at Xerox PARC in the early 1970s, and later evolved into a widely implemented Physical layer, physical and Data link layer, link layer protocol. Fast Ethernet increased the speed from 10 to 100 megabits per second (). Gigabit Ethernet was the next iteration, increasing the speed to . The initial standard for Gigabit Ethernet was produced by the IEEE in June 1998 as IEEE 802.3z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computer Companies Established In 1986
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of compute ...

Wireless Networking Hardware
Wireless communication (or just wireless, when the context allows) is the transfer of information (''telecommunication'') between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth, or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio ''wireless technology'' include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications invo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acquisitions By Cisco
Cisco Systems, Inc., commonly known as Cisco, is an American computer networking company. Cisco made its first acquisition in 1993, which was followed by a series of further acquisitions. History Founded in 1984, Cisco did not acquire a company during the first seven years of its existence; but, on September 24, 1993, Cisco acquired Crescendo Communications, a LAN switching company. Following the first Cisco takeover purchase, acquisitions have constituted 50 percent of the company's business activity. The company's largest acquisition is the purchase of Splunk—a software company that develops software for the analysis and monitoring of machine-generated data—28 billion. Cisco's previous largest acquisition was tied between Cerent Corporation and Scientific Atlanta for $6.9 billion in 1999 and 2005 respectively. The majority of companies acquired by Cisco are based in the United States (U.S.) and a total of 149 companies had been acquired . Most of the compani ...

Aironet ARLAN
ARLAN is a family of both proprietary non- 802.11 and 802.11-compliant wireless networking technologies developed and marketed by Aironet Wireless Communications in the 1990s prior to Aironet's acquisition by Cisco Systems. Operating in the 900 MHz and 2.4 GHz ISM bands and offering a nominal 2.0 Mbit/s throughput, the non-802.11 DSSS products competed directly with NCR's WaveLAN technology. After acquisition, the ARLAN lineup was renamed to Cisco Aironet; the non-802.11 products were supported briefly then discontinued. Hardware The ARLAN lineup consisted of several offerings: 900 MHz DSSS non-802.11 *Half-length ISA card, part number 655-900, RP-TNC connector. Cisco part number 200-001292. * MCA card, part number 670-900, RP-TNC connector *PC card, part number 690-900, large external antenna dongle *900 MHz access point, part number 630-900 *900 MHz bridge, part number 640-900 2.4 GHz DSSS non-802.11 *Half-length ISA card, part number 655-240 ...

Computer Networking
A computer network is a collection of communicating computers and other devices, such as printers and smart phones. In order to communicate, the computers and devices must be connected by wired media like copper cables, optical fibers, or by wireless communication. The devices may be connected in a variety of network topologies. In order to communicate over the network, computers use agreed-on rules, called communication protocols, over whatever medium is used. The computer network can include personal computers, Server (computing), servers, networking hardware, or other specialized or general-purpose Host (network), hosts. They are identified by network addresses and may have hostnames. Hostnames serve as memorable labels for the nodes and are rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the tr ...
