These IoT networks are 'unapologetically slow'

While the International CES this week emphasized home networks and LTE-equipped cars, a different kind of network that can send tiny messages across a city crept toward a future that some people think may be huge.The concept is low-power, wide-area networks (LPWANs), which make up for extremely low data rates by going farther than a cellular signal and working in tiny devices that can last months on a small battery. They won’t carry TV shows or virtual reality games, but they may help to gr
