Department of Telecom (DoT) has exempted wireless devices that operate in low frequency range like bluetooth, wireless chargers, internet-of-things (IoT) products, medical devices etc. from licensing requirement. The move aimed at facilitating ease of doing business for adoption of new technologies like IoT, machine-to-machine (M2M) communications both in industrial and consumer applications.
Henceforth, no licence will be required by any person to establish, maintain, work, possess or deal in any wireless equipment for purpose of usage of very low power radio frequency devices or equipments. It will be application for inductive applications in frequency bands of 302 to 435 KHz (kilohertz), 855 to 1050 KHz and 1.89 to 2.31 MHz on non-interference, non-protection and shared (non-exclusive) basis.
Department of Telecom (DoT)
It is nodal department of Ministry of Communications. It is headquartered in New Delhi. It is responsible for formulating developmental policies aimed at accelerating growth of telecommunication services in the country. It is also grants licenses for various telecom services like Unified Access Service Internet and VSAT service. It is also responsible for frequency management in field of radio communication in close coordination with international bodies. It also enforces wireless regulatory measures by monitoring wireless transmission of all users in the country.
The Telecom Regulatory Authority of India (TRAI) has recommended delicensing of chunk of spectrum in few bands to facilitate smooth roll-out of machine-to-machine (M2M) communications.
TRAI has suggested that no separate spectrum band will be allocated exclusively for M2M services, rather it will utilise existing license exempt airwaves.
Unlike person-to-person (P2P) communication, M2M technologies involve communication between two devices. The technology is basis for automated information exchange between machines. It enables wired and wireless devices to talk to each other using sensors. It is also a key component of the emerging Internet of Things (IoT) revolution. TRAI acknowledged its potential in National Telecom Policy 2012.
Applications of self-communicating machines using M2M communications can be deployed in new-age infrastructure projects and various industry verticals such as smart cities, smart grids, smart homes, smart transportation and smart heath sectors.
TRAI has suggested to Department of Telecom (DoT) that all existing operators should be allowed to provide connectivity for M2M services. Under this technology, devices will be fitted with SIM or universal integrated circuit card (eUICC).
TRAI has suggests delicensing of 1 MHz of spectrum from 867-868 MHz frequencies and another six units from the 915-935 MHz range for M2M communication services.
TRAI has suggested that government, through DoT, should identify critical services in M2M sector and these services should be provided only by connectivity providers using licensed spectrum. It also suggested that companies offering M2M services using unlicensed spectrum should be covered under licence through a new permit to be called Unified Licence (M2M).
