ALOHAnet was an over-the-air wide area network system in Hawaii using ultra high frequency radios and made several assumptions that Metcalfe thought would not be correct in practice. History Xerox PARC (1972–1979) Īfter reading an article on ALOHAnet, Robert Metcalfe became interested in computer networking. 3Com's products, support, and technologies were eventually merged into HPE's Aruba Networks business unit following HP's acquisition of Aruba in 2015 and subsequent split into HPE later that same year. On April 12, 2010, Hewlett-Packard completed the acquisition of 3Com, and it no longer exists as a separate entity. 3Com products were sold under the brands 3Com, H3C, and TippingPoint. From its 2007 acquisition of 100 percent ownership of H3C Technologies Co., Limited (H3C) -initially a joint venture with China-based Huawei Technologies-3Com achieved a market presence in China, and a significant networking market share in Europe, Asia, and the Americas. The company was based in Santa Clara, California. Metcalfe explained the name 3Com was a contraction of 'Computer Communication Compatibility', with its focus on Ethernet technology that he had co-invented, which enabled the networking of computers.ģCom provided network interface controller and switches, routers, wireless access points and controllers, IP voice systems, and intrusion prevention systems. The company was co-founded in 1979 by Robert Metcalfe, Howard Charney and others.

3Com Corporation was a digital electronics manufacturer best known for its computer network products.
