WPC-ETA Approval – Guides & Updates

Ultra-wideband is the quiet revolution inside the last few generations of flagship devices. The precise “find my keys” arrow on a phone locating a tracker tag, digital car keys that unlock only when the owner is actually beside the door, indoor positioning systems tracking assets to within centimetres in a warehouse, radar sensors detecting a

Not every radio transmitter looks like a radio. A Qi wireless charging pad, an induction-based toothbrush charger, an EV charging system, a wireless power bank, an inductive proximity sensor, a metal detector, an anti-theft EAS gate at a shop exit — all of these devices generate radio-frequency magnetic fields in the kilohertz range, and in

Few wireless applications carry stakes as high as medical radio. A cardiac pacemaker that reports arrhythmia data to a bedside monitor, an implanted insulin pump adjusted through a wireless programmer, a continuous glucose monitor streaming to a phone, a swallowed capsule endoscope transmitting images from inside the body — these devices depend on radio links

Below 1 GHz lies the quiet workhorse spectrum of the connected world. Sub-GHz radio — and the 433 MHz band in particular — carries an enormous share of the world’s short-range wireless traffic: car key fobs, gate and garage door openers, wireless doorbells, weather stations, tyre pressure monitoring systems, industrial remote controls, alarm sensors, smart

Radio Frequency Identification (RFID) and Near Field Communication (NFC) have moved from niche logistics tools to core infrastructure across the Indian economy. UHF RFID drives warehouse automation, retail inventory, tolling ecosystems, and asset tracking; 13.56 MHz technology powers contactless payment cards, access control, metro ticketing, and every NFC-enabled smartphone and POS terminal; low-frequency RFID underpins

Wi-Fi and Bluetooth are the two most widely shipped radio technologies on earth, and they sit inside almost every product category entering India — smartphones, laptops, routers, smart TVs, wireless earbuds, speakers, wearables, smart home devices, POS terminals, industrial gateways, drones, and connected appliances. Every one of these products transmits in spectrum regulated by the
