GSM GPRS Ethernet Gateway  

3G/4G Mobile Routing with Wireless Cellular Routers

Wireless cellular router technology makes it possible to establish wireless connections in remote locations for primary or backup data communication. A 3G wireless router or 4G wireless router from Wireless cellular router can be customized with the features required of your application.

CDMA and GSM Networks

Wireless cellular router 3G router and 4G router products operate on over 40 networks worldwide and feature a variety of protocols including LTE, HSPA+, HSUPA, HSDPA, UMTS, EDGE, GPRS, EVDO Rev A and 1xRTT. A Wireless cellular router CDMA router or GSM router provides the flexibility of selecting your preferred service provider and plan based upon your usage needs. Digi wireless cellular routers are certified by most major carriers, including AT&T, Sprint, Verizon, Vodafone and other global carriers.

4G LTE Routers, 4G HSPA+ and 4G WiMAX Routers

Wireless WAN carriers each have their own definition of 4G. According to Wikipedia, “One base advantage of 4G is that it can at any point of travelling time provide an internet data transfer rate higher than any existing cellular services…Two 4G candidate systems are commercially deployed: the Mobile WiMAX standard … and the first-release Long Term Evolution (LTE)…”

Wireless cellular router provides commercial grade HSPA+ routers, WiMAX routers and LTE routers for applications requiring high speed data connection including such as mobile computing, transit, video and electronic signage. Some 4G implementations also provide much lower latency communications, enabling such applications as industrial control, utilities SCADA solutions and other time sensitive applications.

Additional Connectivity Options

In addition to a complete list of cellular standards, Our line of industrial cellular routers and enterprise-class mobile 3G routers and 4G routers support additional device connectivity options including serial (RS-232), USB, Ethernet, Wi-Fi (802.11b/g/n), GPS, I/O, CAN and accelerometer.

Enterprise Class Specifications

Applications in markets such as finance, retail and gaming require added data security and reliability. Features such as async/sync serial ports, stateful firewall inspection, integrated VPN security, and other advanced routing capabilities make Wireless cellular router products ideal for critical and sensitive data. These security features make it possible to integrate high-speed cellular connections into a PCI DSS compliant application.
