The NB-Iot CAT-NB2 technology provides data transfer speed up to 130 kbps, which is five times faster than the current generation of the Internet of Things. The main advantages of the NB-Iot is a large radius of the action of one base station, for a long time of the autonomous operation of the devices and the high penetrating capacity of the signal, which allows sensors and devices to work confidently in buildings with a complex internal structure and in the basements.
“Now our“ Internet of things ”is five times faster compared to what the current generation network can show. In addition, the technology is also characterized by the highest energy efficiency - you connect a regular battery to the water flow sensor in the apartment, and the device will itself transmit readings on a mobile network for 6-8 years, ”said Frederick Vanoschuyze, director of technical innovation and infrastructure.
Together with the manufacturer of MediaTek chips, MegaFon specialists tested NB2 commercial devices. The use of Dual Harq function in them ensured the data transfer rate of about 130 kbps, which in some cases will allow industry, energy enterprises, and housing and communal services to reduce infrastructure costs and use one transmitting device instead of several sensors.
According to the AC & M Consulting research agency, at the beginning of the 3rd quarter of 2019, Megafon serves more than 8 million different IoT devices and, according to this indicator, takes the first place in Russia with a 43%market share. Since the beginning of the year, the number of SIM cards of the operator involved in the "smart" sensors has increased by 1 million units. An additional demand for IOT services will further ensure the housing and communal services sector - from July 1, 2020, it is recommended to equip all new multi -apartment and private houses with automated electricity meters.
Among the IOT solutions of Megafon, socially significant projects occupy a special place. On the territory of the Krasnoyarsk Territory and the Republic of Khakassia, the operator ensures the operation of mobile cardiographers in ambulance machines. In Tyumen and Nizhnevartovsk, IoT Megafon is used in the work of “smart” traffic lights, and in Syktyvkar more than 6 thousand SIM cards of the operator help control street lighting. On the mountain cuts of Kuzbass and Chelyabinsk, the Megafon SIM cards ensure monitoring the movement of white, fuel refueling and auxiliary equipment. In 2019, NB-Iot sensors are the basis of the TPP-1 monitoring system in Yoshkar-Ola.
