Why indoor positioning is a live question in India

Spatial Map is an indoor map and digital twin app that shows the positions your indoor positioning system reports — it does not compute them itself. An indoor positioning system in India works the same way as anywhere else: satellites cannot see inside buildings, so GPS, and India’s own NavIC system, stop being useful at the door. Something inside the building — beacons, anchors, access points or readers — has to take over.

The demand is easy to see. Indian cities have large multi-level malls, airports that handle very high passenger numbers, fast-growing metro rail networks in several cities, and big warehousing and logistics clusters on the edges of the major metros, such as the Bhiwandi area near Mumbai. Each of these has people, equipment or stock that someone needs to find quickly — and each needs a different kind of positioning.

The technologies, compared

TechnologyHow it worksTypical resultGood fit
BLE beacons + phone appThe phone hears fixed beacons and estimates its own positionRoom level to a few metres, depending on beacon density and calibrationVisitor wayfinding in malls and airports
BLE tags + gatewaysGateways hear battery tags; an RTLS engine estimates zone or x/yZone or room presence; x/y with dense gatewaysEquipment, trolleys, staff in large buildings
UWB tags + anchorsTime-of-flight between tags and fixed anchorsOften quoted at sub-metre for industrial systemsForklifts, tools, safety zones
Wi-Fi (fingerprinting, RTT)Devices measured against access pointsCoarse, metres to tens of metresTrends and floor-level counts with existing Wi-Fi
UHF RFID readers and portalsPassive tags read when they pass an antennaPresence at a reader or zone, not continuous positionPallets, cartons, IT assets, baggage
Phone sensors (PDR, geomagnetic)Step counting and magnetic signatures, often fused with BLEVaries widely by buildingApps that must avoid installed hardware

Every accuracy figure depends on the building: concrete, steel racking, glass and crowds all change radio behaviour. Ask vendors for results in a pilot on your own floor, not a brochure number. The RTLS software page explains how positioning engines and the software that displays positions divide the work, and BLE asset tracking goes deeper on tags and gateways.

What each kind of venue usually needs

VenueTypical goalCommon technology
MallsVisitor directions, footfall by zone, tenant and facilities operationsBLE beacons with an app; people counters; Wi-Fi counts
AirportsLocating wheelchairs, trolleys and ground equipment; crowding at security and gatesBLE tags and gateways; RFID for baggage; counters
Metro stationsCrowd flow on platforms and concourses, staff on duty, equipment statusCounters and cameras with on-site analytics; BLE for staff
WarehousesForklift and picker positions, pallets at docks, stock by locationUWB or BLE for vehicles; UHF RFID at docks and portals
FactoriesWIP carriers, tools, people in hazardous zonesRFID between stations; UWB or BLE for tools and safety

Radio rules for positioning hardware in India

  • UHF RFID — India uses the 865–867 MHz band for UHF RFID. It has been licence-exempt for low-power use since the mid-2000s, and the current short-range device rules (notified in December 2021) cover 865–868 MHz on a non-interference, non-exclusive basis, with power and bandwidth limits. Buy readers configured for the Indian band — equipment set for the US 902–928 MHz band is not the same thing.
  • BLE and Wi-Fi — the 2.4 GHz band, and parts of 5 GHz for Wi-Fi, are licence-exempt for low-power equipment, again with conditions.
  • UWB — confirm the regulatory position for the exact equipment with your vendor before you commit.
  • Equipment approval — wireless equipment imported or sold in India generally needs the relevant WPC approval; your hardware supplier should provide it.

Positions of people and the DPDP Act

Tracking a pallet raises no privacy question. Tracking a badge worn by a named employee, or a phone that belongs to a shopper, does. India’s Digital Personal Data Protection Act, 2023 governs digital personal data, and the Digital Personal Data Protection Rules, 2025 were notified in November 2025, with most obligations phasing in over the following 18 months. In broad terms, an organisation deciding why and how data is processed (a “Data Fiduciary”) must give notice, have a lawful basis — consent, or one of the “legitimate uses” the Act lists — keep data secure, and limit it to its purpose.

  • Track equipment, not people, where you can. A wheelchair tag answers most airport questions.
  • Count rather than identify. Zone counts from counters or Wi-Fi need no identity.
  • For staff tags, be specific. Say what is tracked, where, during which hours and why. The Act lists certain employment-related legitimate uses; how they apply to your tracking is a question for counsel.
  • Keep positions briefly. Raw positions for days or weeks, aggregates for longer.
  • Secure the data and know where it goes. Including the vendors that process it for you.

Where Spatial Map fits

Spatial Map sits after the positioning system. Your IPS, RTLS engine or RFID middleware writes positions or reads into a table over HTTP; Spatial Map places them on a multi-floor map of the building, next to the racks, rooms, sensors and stock they relate to, and keeps each row’s history. It is hardware-neutral: it does not sell tags, and it does not compute BLE or UWB positions from signal strength.

  • Floor plans from PDF, DWG or images, traced into rooms, walls, doors, stairs and lifts — or drafted by AI Map for you to review.
  • Walking routes across floors through stairs, lifts and escalators, with a step-free option. There is no live “blue dot” for the visitor.
  • In-app alerts on any table, such as “trolley not seen for 60 minutes”.
  • An app interface in English, Spanish, French, German, Arabic and Chinese; there is no Hindi interface today.
  • Published pricing in US dollars: a 7-day free trial, then Pro at $60 a month or $600 a year for up to four facilities. The MIT open-source edition can be self-hosted on your own servers.

Questions to ask an IPS vendor

  • What accuracy did you measure in a building like ours, and how was it measured?
  • How many beacons, anchors or gateways per 1,000 m², and who maintains their batteries?
  • Is the hardware configured and approved for Indian frequency bands?
  • How do positions leave your system — an API, webhooks, MQTT, files — and in what format?
  • Where is the data stored and processed, and how do you support our DPDP obligations?
  • What does a pilot on one floor cost, and what would make it a failure?
