Tiny Modem Module Simplifies Communication

Oct. 13, 2005

If your embedded design requires a modem, Radicom Research offers a potential solution with its Half-Inch Modem. Actually, the module is a 1- by 1- by 0.3-in. board, but that's still tiny enough. The modem uses an AT command set. It also features Digital Line Guard (DLG) support and a built-in data-access arrangement for direct connect to a telephone line. There's support for data connections up to 56 kbits/s and fax connections of 14.4 kbits/s. Voice recording and playback, dual-tone multifrequency, distinctive ring, and Caller ID detection are supported, too. The module consumes only 65 mA, or 18 mA in sleep mode. Pricing starts at $21. www.radicom.com

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
