Animation Location Technology Choice

Location Technology Selector

Choose a positioning approach by matching requirements to real tradeoffs. Compare indoor and outdoor fit, accuracy, update rate, battery life, infrastructure, coverage, and cost before deciding whether one technology is enough.

-- Recommended technology
-- Fit score
-- Main caveat

Environment first

GNSS works well outdoors but usually fails indoors. Indoor systems need anchors, beacons, readers, or Wi-Fi data.

Accuracy costs

Centimeter and sub-meter location usually needs more infrastructure, calibration, power, or device cost.

Update rate matters

Tracking a moving worker needs different updates than finding a pallet once per hour.

Hybrid is common

Many deployments combine wide-area location with a precise indoor or gateway-level method.

1

Requirements

State what must be located and why.

2

Environment

Indoor, outdoor, or mixed conditions.

3

Accuracy

Match precision to the decision.

4

Constraints

Power, cost, update rate, and infrastructure.

5

Decision

Choose one method or a hybrid.

Requirements Start by describing what location decision the system must support.

What to compare Start with the use case

Location technology is chosen from the decision the user or system must make, not from accuracy alone.

Diagnosis Outdoor coverage drives choice

GNSS and cellular score well when outdoor coverage matters more than indoor precision.

Recommendation Use GNSS/GPS

Use GNSS for outdoor fixes, and add cellular or gateway fallback when coverage is uncertain.

Controls

Pick a scenario, play through the selection stages, then adjust requirements to see which technologies rise or fall.

How the Selector Scores Technologies

The score is a teaching heuristic for shortlisting. It helps explain tradeoffs, but a real deployment still needs a site survey and tests.

Accuracy fit accuracy_fit = penalty_when_typical_accuracy_is_coarser_than_required More precise than needed is acceptable, but it may still lose points through cost or infrastructure.
Environment fit environment_fit = indoor_share * indoor_strength + outdoor_share * outdoor_strength GNSS favors outdoor share; BLE, UWB, Wi-Fi, and RFID favor indoor or local zones.
Constraint fit constraint_fit = power_fit + infrastructure_fit + range_fit + update_fit + cost_fit Deployment constraints explain why the most accurate method is not always the best method.
Total score score = weighted_sum(accuracy, environment, power, infrastructure, range, update, cost) High scores are shortlist candidates. Close scores are a signal to test or combine methods.

Reference Material

Use these cards to connect the selector to practical IoT location decisions.

Quick Reference
GNSS/GPS Good for outdoor tracking with no local infrastructure; weak indoors and higher power than simple tags.
Wi-Fi positioning Useful where Wi-Fi already exists; accuracy depends on survey quality, density, and building changes.
BLE beacons Low-power indoor proximity or room-level tracking; RSSI distance estimates are noisy.
UWB High-precision indoor ranging when anchors are installed and geometry is good.
LoRa location Wide-area, low-power coarse location; useful when exact position is less important.
RFID/NFC Best for identification at portals, shelves, checkpoints, or zones rather than continuous coordinates.
Selection Checklist
State the decision Know whether the system needs a coordinate, a room, a shelf, a zone, or proof of passing a checkpoint.
Match the environment Separate indoor, outdoor, underground, metal, rural, and dense urban conditions before scoring.
Choose needed accuracy Do not demand centimeter accuracy if the task only needs a room, yard, or route segment.
Check update rate Fast movement, safety alerts, or navigation need more frequent updates than inventory audits.
Count infrastructure Anchors, beacons, readers, cabling, calibration, and maintenance often dominate total cost.
Plan fallback Hybrid designs help when the device moves between outdoor, indoor, and no-coverage areas.
Technical Accuracy Notes
Typical accuracy varies Numbers here are approximate. Multipath, antenna placement, calibration, and density can dominate.
RSSI is not a ruler BLE and Wi-Fi signal strength can support proximity, but walls and people make distance estimates noisy.
UWB needs geometry Precision depends on anchor placement, line of sight, clocking, and site-specific installation quality.
GNSS has urban limits Buildings, tunnels, foliage, and indoor areas can make GNSS unavailable or misleading.
Privacy matters People tracking requires clear purpose, consent or policy basis, retention limits, and access control.
Validate on site Always test with real devices, mounting positions, movement, interference, and maintenance workflows.
