Cisco introduced a gateway router designed to extends corporate 3G/4G wireless WAN network services to small devices in challenging environments far beyond the confines of headquarters. 
The Cisco 819 Integrated Services Router (ISR) Machine-to-Machine Gateway brings networking capabilities into non-traditional IP devices for machine-to-machine (M2M) connectivity. Cisco estimates that technologies such as the Cisco 819 ISR will help connect more than 50 billion devices to the Internet by 2020.
The Cisco 819 ISR is optimized to support very large numbers of M2M connections. It offers advanced security features including stateful and application inspection firewall, intrusion prevention, content filtering, and encryption for VPNs, which enables it to be used in sensitive environments. Additionally, its QoS features can optimize voice and video applications in remote sites, so end-users experience the same service levels as they would at headquarters. A hardened version for outdoor deployments can withstand temperatures as low as -13F (-25C) and as high as 140F (60C). http://www.cisco.com
