Other devices requiring wireless connectivity

Integration Reduces Space, Power and Cost. The SocketModem GPRS wireless modem integrates the controller, RF transceiver, antenna interface and SIM socket in one communications device. This integration requires low power, low real estate and provides an overall reduction in costs.

Reduces Development Time. The SocketModem GPRS wireless modem enhances your product while you focus on developing its core features. It actually provides faster time-to-market because it relieves the burden and expense of obtaining PTCRB and RF approvals.

Internet-enabled. The SocketModem GPRS wireless modem includes an embedded TCP/IP protocol stack to bring embedded Internet connectivity to any device. Using the Internet protocols and the wireless connection to an IP network, it sends and receives data over the Internet.

SocketModem GPRS Pin-Out. The SocketModem GPRS wireless modem interfaces easily with existing products through a standard serial communication channel. The serial DTE channel is capable of transfer speeds to 115.2K bps and can be interfaced directly to a UART or microcontroller. The complete on-board RF transceiver interfaces with an antenna for direct connection to wireless SMS, circuit-switched dial-up, or packet data networks. It also includes an onboard LED to display network status.

Universal Socket Connectivity. Multi-Tech’s universal socket is a flexible, comm-port architecture that provides cellular, Ethernet, PSTN or Wi-Fi network access with interchangeable communications devices. This means you can utilize one system design and populate it with your connectivity device of choice accommodating multiple connectivity requirements. In addition, you are assured a seamless migration to future technologies.
