The Nokia 30 is a ‘GSM Connectivity terminal’ which lets you control stuff remotely from your mobile phone. It’s dual band, can attach via a serial port and can also act as a wireless modem. It’s part of the company’s range of M2M (machine to machine) products, which I think show off some of Nokia’s coolest technologies.
‘…attach the Nokia 30 terminal to a device such as electric door lock, heating system or domestic alarm, and you can monitor and control the device’s status by text messages with your own mobile handset.’
