There are three main ways to locate people and assets indoors: UWB time-of-flight ranging, Bluetooth Direction Finding (AoA\/AoD), and BLE proximity via RSSI<\/a>. (1)(2)(3)<\/a><\/sup><\/p>\n\n\n\n

How Each Indoor Positioning Technology Really Works<\/h2>\n\n\n\n

Ultra-Wideband (UWB): High-Precision Time-of-Flight Ranging<\/h3>\n\n\n\n

UWB systems use time-of-flight ranging procedures between participating devices to measure distance. (3)<\/a><\/sup> In Lansitec\u2019s UWB Anchor<\/a> system, anchors synchronize timing, calculate distances to nearby UWB trackers<\/a>, and can provide up to 10 cm accuracy with a specified receiving range up to 23 m (environment-dependent). (4)<\/a><\/sup><\/p>\n\n\n\n

BLE Angle-of-Arrival (AoA): Direction-Aware Bluetooth Positioning<\/h3>\n\n\n\n

Bluetooth Direction Finding adds standardized direction to Bluetooth LE signals via Angle of Arrival (AoA) and Angle of Departure (AoD) methods. In AoA, a transmitter (for example, an asset tag) uses a single antenna, while the fixed receiving locator uses multiple antennas arranged in an array to collect data used to compute signal direction. (2)<\/a><\/sup> Bluetooth\u2019s technical overview also describes the limitations of traditional beacon positioning and why direction finding improves what can be derived from the RF signal. (1)<\/sup><\/a><\/p>\n\n\n\n

\u201cMost of the cost is infrastructure, not the tags\u201d<\/em> is generally true in practice, but the exact cost split is deployment-specific.<\/p>\n\n\n\n

BLE Proximity (RSSI): Simple & Scalable Zone-Level Tracking<\/h3>\n\n\n\n

Classic BLE proximity estimates distance from received signal strength (RSSI<\/a>) and a reference transmit power value, but it is often not accurate enough for higher-precision use cases and can be affected by environmental conditions. (1)<\/a><\/sup> Lansitec\u2019s LoRaWAN Micro Bluetooth Gateway<\/a> is an example of an RSSI-driven proximity approach, advertising 3 m indoor accuracy, IP68 enclosure, and 6-plus years of battery operation under stated scanning conditions. (5)<\/a><\/sup><\/p>\n\n\n\n

We\u2019ve learned to treat these as layers, not rivals. UWB gives you surgical precision where centimetres matter; BLE gives you breathable coverage everywhere else. (4)(5)<\/a><\/sup><\/p>\n\n\n\n

How to Smartly Choose the Right Technology by Use Case<\/h2>\n\n\n\n

When to Use UWB:<\/strong> Mission-Critical Centimeter Accuracy, and you want published system constraints you can design around (accuracy, receiving range, device capacity, environmental ratings).<\/p>\n\n\n\n

When BLE AoA Makes Sense:<\/strong> Directional Indoor Positioning, and you can deploy fixed locators with antenna arrays in the environment. Exact \u201c1\u20133 m dot\u201d expectations vary widely with locator density, mounting height, and multipath.<\/p>\n\n\n\n

UWB anchorsWhen BLE Proximity Wins: <\/strong>Long Battery Life & Wide Coverage, and zone\/room-level presence is enough. RSSI<\/a> proximity can be made useful at scale, but it remains sensitive to environment and calibration. Micro gateways<\/a> and UWB anchors<\/a> can both use a LoRaWAN<\/a> backhaul in Lansitec\u2019s portfolio, which simplifies pilots and rollouts.<\/p>\n\n\n\n

Infrastructure & Power Planning: The Hidden Success Factor<\/h2>\n\n\n\n

This stage often determines whether a project succeeds or fails.<\/p>\n\n\n\n

Anchor spacing and geometry: If you\u2019re using Lansitec UWB Anchors, the published receiving range is up to 23 m, which sets an upper bound for layout sketches, then you tighten spacing based on the site. (4)<\/sup><\/a><\/p>\n\n\n\n

Device density and lifetimes: Lansitec specifies up to 512 UWB trackers<\/a> per anchor and a stated battery-life envelope (depending on density and reporting). (4)<\/sup><\/a> For Micro Bluetooth Gateways<\/a>, Lansitec specifies >500 beacons<\/a> tracked, plus payload\/airtime handling details that impact network planning. (5)<\/a><\/sup><\/p>\n\n\n\n

Backhaul: In the cited Lansitec examples, UWB Anchor<\/a> data and Micro Gateway BLE data are sent via LoRaWAN<\/a>.<\/p>\n\n\n\n

Cost & TCO Comparison: What You\u2019ll Really Pay<\/h2>\n\n\n\n

UWB accuracy<\/a> is fundamentally tied to time-of-flight ranging procedures and system design. (3)<\/a><\/sup> In Lansitec\u2019s implementation example, the UWB Anchor<\/a> emphasizes long-life industrial batteries (spec\u2019d as Li-SoCl\u2082 19000mAh\u00d74) and environmental hardening (for example, IP66 and industrial temperature ratings). (4)<\/a><\/sup><\/p>\n\n\n\n

With BLE AoA, the Bluetooth SIG describes the need for antenna arrays and fixed locator infrastructure for direction finding. (2)<\/a><\/sup> Your real-world cost profile will depend on cabling, mounting, and compute architecture.<\/p>\n\n\n\n

BLE proximity offers the simplest roll-out path: you can deploy gateways<\/a> and get room\/zone-level presence quickly. Lansitec\u2019s Micro Gateway positions itself as a low-maintenance option with stated longevity, ruggedization, and RSSI-driven precision targets. (5)<\/a><\/sup><\/p>\n\n\n\n

Why Hybrid BLE + UWB Systems Consistently Win<\/h2>\n\n\n\n

We often run a BLE blanket + UWB islands. Why? Because the hybrid system works in two layers:<\/p>\n\n\n\n

    \n
  1. Deploy Micro Bluetooth Gateways<\/a> for broad presence and zone alerts (RSSI-driven positioning), with long battery life and high beacon capacity. (1)(5)<\/li>\n\n\n\n
  2. Add UWB Anchors around choke points and high-value zones where tighter accuracy is needed, using the UWB Anchor\u2019s stated accuracy and range envelope as your design constraints. (3)(4)<\/a><\/sup><\/li>\n<\/ol>\n\n\n\n

    Both layers can ride the same LoRaWAN<\/a> backhaul in the Lansitec examples, which keeps operations saner.<\/p>\n\n\n\n
