BARCELONA — At Mobile World Congress, hundreds of companies showed off new smart city technologies, some that are just in the start-up phase while others are being implemented in select cities.

One concept further along in deployment is a smart parking meter made by Paris-based Parkeon that’s in use in 12,000 locations, ranging from New York City to beaches in Australia. Parkeon showed a deluxe meter that takes credit cards and includes a display that can offer news. In Sydney, for instance, the parking meter provides tips on surfing conditions off the Australian coast.

During MWC, Parkeon and Sierra Wireless announced that Sierra Wireless AirPrime HL Series embedded modules will be used to enable cellular connections to the smart city parking meters, running on 2G, 3G and 4G technologies.
