Digital Ocean, Inc., was a maker of wireless products from 1992 to 1998, when it was bought by Harris Semiconductor and its assets made part of Harris's Intersil Division, which was spun off in 1999 into Intersil Corporation. The company was founded in May 1992 by Jeffery Alholm and headquartered in Lenexa, Kansas. Several contracts with Apple Inc.,〔 AT&T, Aironet Wireless Communications〔 (later acquired by Cisco as its wireless LAN division), Harris Semiconductor, the United States Department of Defense,〔(【引用サイトリンク】url=http://digitaloceaninc.files.wordpress.com/2012/08/announcement-23-september-1994-dept-of-defense-goes-wireless-at-medical-centers-do-supplies-dod-with-newton-wireless-connectivity.pdf )〕 and several others made Digital Ocean the leader in developing and manufacturing state-of-the-art wireless products for the entire line of Apple’s desktop, portable, and pen-based devices. It was a co-developer of the IEEE 802.11 wireless standard and of the industry’s first 802.11 chipset. It developed the Seahorse, arguably the world's first smartphone. In addition, by specializing in rapid, custom development, the company concluded multiple individual development contracts for application specific wireless products in vertical markets. Digital Ocean was granted approximately 20 patents for its development of wireless technologies. In 1998 it was sold with its assets to Harris Semiconductor to become part of their Intersil division; Intersil was then spun off from Harris one year later. ==Products== Starfish Wireless Access Point for LocalTalk and EtherTalk Macintosh Starfish with Microcellular Roaming Software〔(【引用サイトリンク】 url=http://digitaloceaninc.files.wordpress.com/2012/08/starfish-ad-page.pdf )〕 Enabled seamless roaming. Starfish II Ethernet Access Point ''Business Wire Magazine'' explained, "The Starfish II connects to wired networks and acts as the access provider for Manta and Digital Ocean's other station products." Manta 500EN EtherTalk Wireless Station with AAUI Connection〔 Manta 10BaseT Wireless network connections at full ethernet speeds.〔 Grouper Line The Grouper line of products were networking devices that used spread-spectrum radio waves to communicate. Groupers could be attached to any PowerBook or used freestanding with any desktop Mac. Placing one Grouper on a wired network would have it serve as a hub for up to 15 other wireless Groupers. Keeping with Digital Ocean's theme, the collection of networked computers was called a school. Wireless devices could access the Grouper-enabled network from within a 250-foot distance indoors to an 800-foot distance outdoors, and the Grouper only used one-sixtieth the power of other comparable wireless devices. * 200LTS Wireless LocalTalk Station for Macintosh〔 * 100MPS Wireless local area connectivity for all Newton MessagePads. * 100MPS+ Wireless local area connectivity for all Newton MessagePads; included additional port for serial devices, such as wand barcode readers, laser barcode scanners, and printers. * 105MPS Package included Grouper 100MPS+ with Digital Ocean Pen Reader, bundled with AllPen barcode software for wireless data collection. * 100LTS LocalTalk for Macintosh The original Wireless LocalTalk station for Macintosh that mounted directly to the bottom of 100xx PowerBooks. Tarpon All-In-One PDA The Tarpon integrated an Apple Newton and Digital Ocean Grouper〔 with backlighting, a water-resistant and ruggedized case, and built-in wireless LAN, WAN, modem, voice capability for anything from simple peer-to-peer conversations to full telephony, and optional GPS via the PCMCIA slot.〔〔(【引用サイトリンク】 url=http://digitaloceaninc.files.wordpress.com/2012/08/tarpon-tech-specs.pdf )〕 The addition of wireless capabilities to Newton-based devices was called "a major step forward" because "without it, they are not really useful." The Tarpon began as the SuperTech 2000, but was then further modified and released to the general public under the new name. Seahorse A rugged handheld computer based on the Newton OS 2.0, the Seahorse was backlit, lightweight, and durable, with a variety of integrated communication capabilities: the first CDPD modem ever in a wireless PDA, PCMCIA slot, WLAN modem, and a modular snap-on nose for optional GPS and diffused infrared capabilities. A rugged boot protected Seahorse, while large-capacity, slide-in rechargeable batteries provided around eight hours of continuous use. Together these features made Seahorse a good solution for: remote handheld access to customer service databases, wireless Internet access, precision location applications utilizing handheld GPS systems, and wirelessly accessing corporate and Internet databases to utilize schematics and manuals while in the field.〔(【引用サイトリンク】 url=http://digitaloceaninc.files.wordpress.com/2012/08/seahorse-product-brochure-p-1.jpeg )〕〔(【引用サイトリンク】 url=http://digitaloceaninc.files.wordpress.com/2012/08/seahorse-product-brochure-p-2.jpeg )〕 Digital Ocean began sales of the Seahorse in 1996. Though not its original intention, the Seahorse arguably contained all the intellectual property and engineering in one integrated device to constitute the world’s first smartphone,〔 as defined by four parameters: # a PDA # with an integrated data/voice phone # which can access the Internet via a graphical browser # and complete email tasks ''Business Wire Magazine'' wrote, "'The UB-1 provides Seahorse with a fully featured, economical module in an easy to integrate form factor,' said Jeff Alholm, president and chief executive officer of Digital Ocean. 'Combining PCSI's proven cellular voice and data technology with Seahorse's power performance and options makes Seahorse a leading industry choice for users seeking a versatile and affordable handheld computer.'"〔 As such a groundbreaking product, the Seahorse received the Cellular Telephone Industry Association’s (CTIA) 1996 award for Product of the Year.〔 Skyway Bridge ''Business Wire Magazine'' said, "Skyway Bridge wirelessly connected Ethernet-compliant networks in multiple buildings at distances up to 20 miles apart and can be used in conjunction with Digital Ocean's in-building wireless LAN products, including Starfish II, Manta II and Grouper. With a bandwidth of 2 Mbps, Skyway Bridge is faster and less expensive than T1 lines." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Digital Ocean」の詳細全文を読む スポンサード リンク
