4G mobile hotspots
21 March 2012, Telecoms, Datacoms, Wireless, IoT
Designed to take advantage of high-speed mobile broadband connectivity offered by new 4G networks, Sierra Wireless’ AirCard 753S and AirCard 754S Mobile Hotspots connect up to five Wi-Fi enabled devices simultaneously to the Internet over dual-carrier HSPA+ and LTE networks, respectively.
The devices are about the size of a deck of cards, lightweight and easy to set up and use; with no software to install, the average user can be connected in less than one minute. An integrated LCD display provides all the necessary information, including WiFi access information, battery life, network signal strength, and the number of devices connected. Audible alerts and an intuitive web interface also provide easy monitoring of device status. The web interface, which can be accessed from any common web browser, provides an intuitive way for users to change the hotspot’s administrative and security settings.
In areas where 4G network coverage is not available, both models automatically switch over to 3G networks, ensuring continuous connectivity and roaming across network boundaries. The vastly improved speeds offered by 4G networks provide users with plenty of bandwidth, even when shared across multiple devices. The AirCard 753S offers downlink speeds of up to 42 Mbps and uplink speeds of up to 5,76 Mbps on a DC-HSPA+ network. The AirCard 754S offers downlink speeds of up to 100 Mbps and uplink speeds of up to 50 Mbps when operating on an LTE network.
