U.S. Robotics Corporation, often called USR, is a company that produces USRobotics computer modems and related products. Its initial marketing was aimed at bulletin board systems, where its high-speed HST protocol made FidoNet transfers much faster, and thus less costly. During the 1990s it became a major consumer brand with its Sportster line. The company had a reputation for high quality and support for the latest communications standards as they emerged, notably in its V.Everything line, released in 1996.

With the reduced usage of analog or voiceband modems in North America in the early 21st century, USR began branching out into new markets. The company purchased Palm, Inc. for its PilotPDA, but was itself purchased by 3Com soon after. 3Com spun off USR again in 2000, keeping Palm and returning USR to the now much smaller modem market. After 2004 the company is formally known as USR. It is one of the few companies left in the modem market today, and now employs about 125 people worldwide.^[1]

USR was founded in 1976 in Chicago, Illinois (and later moved to Skokie, Illinois), by a group of entrepreneurs, including Casey Cowell, who served as CEO for most of the company's history, and Paul Collard who designed modems into the mid-1980s. The company name is a reference to the fictional company U.S. Robots and Mechanical Men which featured prominently in the works of Isaac Asimov. The company has stated it was named as an homage to Asimov because in his science fiction works U.S. Robots eventually became 'the greatest company in the known galaxy',^[2] and USR appeared in I, Robot (2004) as the fictional company itself.^[3]

USR was one of many companies to offer dial-up modems for personal computers. Prior to the development of standards such as the V.32 family of protocols, USR introduced its own HST (High-Speed Transfer) protocol in 1986, which operated at 9600 bit/s (bits per second). In 1989 HST was expanded to 14.4 kbit/s, 16.8 kbit/s in 1992, and finally to 21 kbit/s and 24 kbit/s.

USR was not the only company making modems with proprietary protocols; Telebit's TrailBlazer series offered speeds up to 19.2 kbit/s, and Hayes also introduced the 9600 bit/s Express 96 (or 'Ping-Pong') system. However, USR became the most successful of the three, due to a marketing scheme that offered large discounts to BBSsysops.

The proprietary nature of HST allowed USR to maintain its market predominance even when off-brand V.32-based modems began selling for less than equivalent HST modems. As the price differential decreased, however, V.32-based modems eventually became a cost-effective alternative to HST. USR countered by creating ever-faster HST protocols, starting with a 16.8 kbit/s mode, and by producing 'dual-standard' modems that were able to communicate with both HST and V.32 modems at high speeds.

During this period, USR differentiated between its high and low-end product lines by supporting only the V.32 modes on its low-end Sportster models, while its high-end Courier models supported V.32, HST, or both in the Courier Dual Standard models. The Sportster used the same motherboard as the Couriers, and on certain 14.4 kbit/s models a sequence of AT commands could be issued to enable the faster 16.8 kbit/s HST mode.^[4] The Courier modems remained a favorite in the BBS and emerging Internet service provider world, where they were known to run without problems for extended periods of time (although the initial large-scale deployment of Courier modems in the CompuServe network uncovered a serious bug, which would cause the modems to crash and stop answering calls under high call volumes).

A similar situation emerged a few years later when the 56kbit/s V.90 standard was first being proposed. USR developed its own 56k standard known as X2, while a consortium of other companies introduced its own K56flex. In contrast to the success of HST, neither X2 nor K56flex saw any real market uptake, as it was clear they would soon be followed by V.90 modems. After the introduction of V.90, USR abandoned support for X2. In a further effort to reduce the retail price of its modems, USR also marketed a Winmodem that used software running on the host computer to perform some of the modem functions.

Some models of Courier modems were known for their long-term upgradeability, because they used an upgradeable DSP design. For example, when the Courier V.Everything modem was first released in 1994 under the product label 'Courier V.34 Ready'.,^[5] it shipped with only V.FC support, because V.34 had not been released. A free V.34 firmware upgrade^[6] was made available later via FidoNet, as well as the Internet. USR then surprised many early Courier V.Everything modem owners with a limited-time free offer of an X2 firmware upgrade, which added 56K speed capability. Finally, USR released a V.90 upgrade that was compatible with X2-upgraded Courier V.Everything modems. Even the 1994 hardware released pre-V.34 was fully V.90-upgradeable without hardware modification.

There was a licensing key needed for some Courier V.Everything V.90 flash upgrades. The firmware could be loaded onto the modem, but it would work in 'degraded' V.34 mode. After paying a fee, and having the modem dial USR, a license key was installed that enabled the V.90 functions.

Commoditization[edit]

USR acquired Palm, Inc. in 1995 and subsequently merged with 3Com Corporation in June 1997.^[7] It was then recreated as a spin-off of 3Com in June 2000, assuming 3Com's entire client modem business except for the Palm-related portion, which itself had been spun off with Palm three months earlier. Other portions of the original USR remained part of 3Com as the CommWorks Corporation. USR then quickly built up its device portfolio, including not only traditional dial-up modems, but also wired- and wireless-networking components.

USR was acquired by private equity firm Platinum Equity for an undisclosed amount of cash in 2005, believed to be between US$30 million and US$50 million.^[8]

By 2010 the company was focused only on the traditional modem business.

In 2013, USR was acquired by UNICOM Global.^[9]

U.S. Robotics’ Raise 802.11g Speed to 100 Mbps

ATLANTA – June 03, 2003 – U.S. Robotics® is enabling wireless network users to send and receive data faster, more securely and with greater compatibility. Announced today at SuperComm 2003 (Booth 10819), U.S. Robotics 802.11g Wireless Turbo family is powered by the company’s exclusive “Accelerator Technology,” which increases performance levels up to 100 Mbps1 on a single channel. Available in July throughout North America, the U.S. Robotics 802.11g Wireless Turbo portfolio includes a router, multi-function access point, PCI adapter and PC card.
“U.S. Robotics’ exclusive Accelerator Technology provides our Wireless Turbo users with 54 Mbps accelerated to 100 Mbps performance,” said Kevin Goulet, director of product management for U.S. Robotics. “The new portfolio is actually capable of delivering data with the fastest throughputs available—nearly double over other 802.11g products.”
To ensure the fastest data throughput rates at all times, U.S. Robotics designed the 802.11g Wireless Turbo line for total compatibility with all 54 Mbps 802.11g, 22 Mbps and 11 Mbps 802.11b wireless devices. Competitive products will commonly experience network slowdowns in mixed mode networking environments, which essentially sacrifices data throughput for compatibility. U.S. Robotics 802.11g Wireless Turbo products ensure that each device will securely connect independently at the highest speed possible with any combination of 54 Mbps 802.11g, 22 Mbps and 11 Mbps 802.11b wireless devices.
Unlike other high-speed networking technologies, Goulet added that U.S. Robotics maximizes network capacity by placing all the speed on a single channel. “Our Wireless Turbo users reap the benefits of the speed purchased due to greater compatibility with 802.11g and 802.11b. Each device connects at the fastest speeds possible, which is important for network owners with multiple users who require the highest performance to be maintained,” he said.
Because security is a critical concern in any network, U.S. Robotics 802.11g Wireless Turbo products are designed to be up to 10 times more secure than standard wireless networking products. This high level of integrated security includes a number of features to make wireless networking safe and reliable. Built-in 256-bit Wired Equivalent Privacy (WEP) encryption, 802.1x network authentication, and MAC address authentication provides a highly secure, yet easily maintained wireless network. Additionally, all U.S. Robotics 802.11g Wireless Turbo products will also support Wi-Fi Protected Access (WPA) encryption once the 802.11i security standard is ratified. Users can work wirelessly with the confidence of knowing they have the highest level of security protecting their network data and communications.
The versatility and ease of use of U.S. Robotics 802.11g Wireless Turbo products mean a wireless network can be easily set up with an existing wired network without expensive infrastructure costs. A quick and easy three-step installation process instantly allows users to be more productive with their new wireless network. The unique, stackable case design of the router and multi-function access point require minimal space, so that both home network users and small-to-medium size business owners alike can grow their networks with an entire family of other U.S. Robotics networking and broadband devices.
The U.S. Robotics 802.11g Wireless Turbo product line includes the following solutions designed to optimize any network:

• U.S. Robotics Wireless Turbo Access Point & Router is ideal for sharing a high-speed cable or DSL Internet connection, data files, music and games among multiple computers. The router includes four products in one—an 802.11g Wireless Turbo Access Point, 4-port Ethernet switch, router and firewall. (Model 8054)
• U.S. Robotics Wireless Turbo Multi-Function Access Point is a professional-grade access point that has the power and features of a high-performance client adapter for Windows and non-Windows devices. The access point includes five products in one—an Access Point, Bridge, Multi-Bridge, Client and Repeater. The repeater function relays signals across multiple access points for greater wireless range and coverage, and a powerful class-leading ARM9 processor that allows for maximum data transfer in large, critical networks. The device is capable of bridging both wired and wireless networks, includes full SNMP management for network administration, and incorporates configurable transmit/receive power control for optimal network configuration. (Model 5450)
