How Smart Cities Are Making Safety a Top Priority
Creating a safe, secure city requires preparing for a wide variety of challenges, from protecting critical infrastructure to mitigating the risks of terrorism and cyber attacks. Deploying a 24/7 crime prevention and public safety strategy is essential to proactively maintain safety, while also allowing emergency professionals to respond quickly in a crisis situation.
Firefighters, police and rescue services depend upon wireless communications. Police officers check remote databases for outstanding warrants. Paramedics need to access medical histories and patient data. Firefighters often need blueprints and building plans. Better data enables first responders make better decisions, but traditional radio communications have limited bandwidth and are difficult to integrate with other systems. Public LTE networks can offer more bandwidth and geographic coverage, but these networks are vulnerable to overloading and interruption during emergency events.
Fortunately, 4G LTE routers can connect to dedicated emergency first responder networks like AT&T’s FirstNet™. These provide reliable, high-bandwidth, wireless data communications for public safety agencies and supporting organizations. Where mobility is required, LTE routers provide that, too. LTE routers, such as the ICR-3241 from Advantech, serve as a mobile gateway with LTE, Wi-Fi and GPS to support connectivity to critical web applications. LTE routers support modern security technologies and prevent unauthorized intrusion into sensitive information. They connect with modern data networking equipment as well as legacy devices, such as RS-232 fingerprint scanners and streetlight control terminals, thus protecting investments in older technologies.
Much of what enables innovation in city environments is built on high-speed physical layer connectivity. A hybrid deployment of both fiber and wireless is essential for communities to support converged broadband connectivity, which promotes edge computing, 24/7 performance expectations and economic development.
Low-Power Wide-Area Network (LPWAN) technology is also a key element to fulfill growing smart city demands. LoRaWAN, a type of LPWAN designed specifically for wide-range, low-power communications, is ideal for smart city applications because it enables wireless, battery-operated IoT and secure bidirectional communication, mobility and localization service. To make building a wireless LoRaWAN IoT environment quick and easy Advantech provides sensor nodes, gateways and cloud services.
