Canopy – A line-of-sight wireless technology, primarily used by ISPs to provide broadband internet; MotoMESH – A mobile wireless broadband product providing proprietary "Mesh-Enabled Architecture" and standards-based 802.11 network access in both the unlicensed 2.4 GHz band and the licensed 4.9 GHz public-safety band
Good audio characteristics. Some modems have an uncorrectably low signal volume or produce audio noise. Some modems are unable to recognize all but the best DTMF signals. Some modems do a poor job of recording, or detecting and reporting silence or the end-of-call voltage reversal, which some applications need. Support for caller ID, if needed ...
In 1994, Motorola re-organized ISG and combined Codex with Universal Data Systems products. The new group was called the Internet and Networking Group, [9] with John Lockitt remaining president and chief executive of Motorola Codex. [10] After the dot-com bubble collapse in 2000, Motorola was forced to close or sell off some of their own ...
Motorola was founded in Chicago, Illinois, as Galvin Manufacturing Corporation (at 847 West Harrison Street) [9] in 1928.. Paul Galvin wanted a brand name for Galvin Manufacturing Corporation's new car radio, and created the name "Motorola" by linking "motor" (from motor car) with "ola" (from Victrola), which was also a popular ending for many companies at the time, e.g. Moviola, Crayola.

Early modems were devices that used audible sounds suitable for transmission over traditional telephone systems and leased lines. These generally operated at 110 or 300 bits per second (bit/s), and the connection between devices was normally manual, using an attached telephone handset. By the 1970s, higher speeds of 1,200 and 2,400 bit/s for ...
Frequent use of a serial port is for a direct computer-to-computer connection. This requires an adapter called a null modem, which isn't actually a modem in the traditional sense, but rather a connector plug that simply crosses the complementary pins on two serial ports so the two sides can communicate.
However, a modem generally provides few other network functions. A USB modem plugs into a single PC and allows a connection of that single PC to a WAN. If properly configured, the PC can also function as the router for a home LAN. An internal modem can be installed on a single PC (e.g. on a PCI card), also allowing that single PC to connect to ...
