U.S. Robotics Courier Cellular Modem/Wireless Router

Easy Conversion of Legacy Dial-up Solutions to the Cellular Network

The new USRobotics® Courier® Modemulator™ and Cellular M2M Gateway is a drop-in cellular replacement for legacy analog systems that require peer-to-peer connectivity. Emulating a dial-up modem allows equipment to seamlessly connect over a cellular network instead of over the PSTN in legacy M2M applications. Existing legacy hardware and software systems remain untouched when used with the Modemulator - providing extended product life and simplified cellular deployments. Compatibility with both the PSTN and packet switched data networks provides network flexibility that allows an open ended transition plan and eliminates the need for a system overhaul - saving both time and money. By providing a 2-in-1 device, analog customers can transition select sites to cellular in the most efficient and cost-effective way while utilizing the network that is right for the situation. USR's Modemulator & Cellular Gateway provides reliable, secure connections for mission critical M2M applications.

The gateway provides LAN to WWAN routing and GPS functionality in a single device certified on all major 3G cellular networks (CDMA/EVDO and WCDMA/HSPA+). An embedded serial port allows quick implementation for a wide variety of serial based systems already out in the field making it ideal for M2M Serial applications including remote maintenance and control, Point of Sale, monitoring, and automation. The Courier Cellular Gateway is simple to configure locally or remotely from your PC, tablet or smartphone with the cloud based management system allowing fast implementation - reducing customer costs significantly and lowering the entry barriers to a wide range of M2M solutions and an easier transition from analog to cellular. USRobotics' Courier Modemulator & M2M Cellular Gateways continue to offer reliable, secure connections for mission critical applications - for both GSM and CDMA networks allowing more flexible and cost-effective global solutions.
