Professional two-way radio for industry, public safety and site operations across India, including ATEX-certified intrinsically safe transceivers for refineries, chemical plants and other hazardous areas. ASPL supplies handhelds, mobiles and repeater systems, and handles programming, licensing guidance and fleet rollout.
Land mobile radios are the handheld and vehicle-mounted two-way transceivers used by security teams, warehouse and port staff, construction crews, and factory floors to talk instantly across a site without relying on a mobile network. The category spans simple licence-free radios for small teams, licensed analog and digital handhelds and mobiles for larger operations, repeaters and controllers that extend coverage across a campus, and ATEX-certified intrinsically safe units built to operate around flammable gases and dust.
Two radios can talk directly to each other on a single shared channel (simplex), which is fine over short distances but limited by terrain, walls and antenna height. A repeater listens on one frequency and retransmits on another (duplex), picking up a low-power handheld's signal and rebroadcasting it at higher power from a rooftop or tower antenna to cover an entire site or town. Radios that transmit outside the small set of licence-free channels set aside for short-range use need a wireless operating licence from India's WPC (Wireless Planning and Coordination) wing, which assigns the frequency and authorises the equipment for that use.
