About Wireless Modems

Wireless modems transmit modulated data using electromagnetic waves. This grouping includes radio modems ad access points. Radio modems are radio frequency transceivers for serial data. They connect to a serial port (RS232, RS422, etc.) and transmit to and receive signals from another matching radio modem. Access point enables wireless network connectivity. A modem (Modulator-Demodulator) is a device or program that enables a computer to transmit data over telephone lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.

Products & Services Related to Wireless Modems

Access Points

Access points are transmitter / receivers (transceivers) that connect to a network through an interface such as a bus or connector. They receive, store, and transmit data between the wireless LAN and the wired structure.

Network Modems

Network modems (modulators-demodulators) are devices or programs that allow computers to transmit data over telephone lines. They convert digital computer data to analog sound waves and then demodulate the carrier signals to decode the transmitted information.

Radio Modems

Radio modems are radio frequency transceivers for serial data. They connect to serial ports (RS232, RS422, etc.) and transmit to and receive signals from another matching radio modem.
