Full Form of SRD
What is SRD?
A Short Range Device (SRD) refers to a category of radio frequency (RF) gadgets that operate over limited distances, typically up to a few hundred metres. These devices transmit at very low power, which is why they do not require an individual spectrum licence from regulators like the Telecommunication Engineering Centre (TEC) in India. Common examples include Bluetooth speakers, Wi-Fi routers, remote-controlled toys, wireless doorbells, and RFID tags used in malls and toll plazas across the country. In India, SRDs are governed under the National Frequency Allocation Plan and play a vital role in the rapidly growing Internet of Things (IoT) market, smart home systems, and contactless payment infrastructure. The Department of Telecommunications classifies these devices into specific frequency bands, with sub-1 GHz and 2.4 GHz being the most common. For students preparing for competitive exams like GATE, IES, or UPSC, understanding SRD classification is important as it appears in technical sections dealing with wireless communication and spectrum management. Businesses rely on SRDs for indoor communication, asset tracking, and automation, making them the backbone of modern low-power wireless networks across the country.
