UWB Active Tag	Ultra-Wideband ranging using time-of-flight or time-difference-of-arrival. Often supports IEEE 802.15.4z security features.	Typically about 10–30 cm in a well-designed installation. Performance depends on anchor geometry, line of sight, multipath, and calibration.	Requires UWB anchors or gateways using a compatible channel plan, ranging method, antenna design, and location engine. A tag is not automatically compatible with every UWB network.	Common UWB allocations are within the 3.1–10.6 GHz regulatory range, but permitted channels and power limits vary by country.	Usually rechargeable or replaceable lithium battery. Typical field life is approximately 6–24 months, depending on update rate, motion detection, transmit power, and temperature.	Industrial automation, tool tracking, worker safety, warehouse vehicle tracking, healthcare asset location, and high-value equipment monitoring.	CE / RED FCC UKCA RoHS REACH UN 38.3 for lithium batteries	Confirm country-specific UWB channels, indoor-only restrictions where applicable, transmit-power limits, antenna configuration, cybersecurity controls, and battery transport documentation.
Bluetooth Low Energy Tag	Bluetooth Low Energy advertising packets, with optional Bluetooth direction finding, angle-of-arrival, or angle-of-departure support.	Approximately 1–5 m with well-calibrated RSSI systems. Direction-finding installations can provide better accuracy, but require compatible antenna arrays and software.	Compatible with BLE gateways, smartphones, tablets, and standard Bluetooth scanners. Advanced direction finding requires support in both tags and infrastructure.	2.4 GHz ISM band, using Bluetooth LE channels defined by the Bluetooth specification.	Coin-cell, replaceable, or rechargeable battery. Typical battery life ranges from several months to multiple years, depending on advertising interval, sensor use, and transmission power.	Indoor asset tracking, retail, hospitals, visitor management, cold-chain monitoring, proximity alerts, and low-cost deployments across multiple countries.	Bluetooth SIG qualification CE / RED FCC UKCA RoHS REACH UN 38.3 where applicable	Check Bluetooth qualification status, regional radio approvals, privacy settings, gateway density, coexistence with Wi-Fi, and compatibility with the selected cloud or location platform.
Active RFID Tag	Battery-powered radio identification tag, commonly using proprietary or standards-based active RFID communication.	Commonly about 1–5 m in zone-based systems. Accuracy varies substantially with antenna layout, radio protocol, and site conditions.	Requires readers and antennas using the same active RFID protocol and frequency. Interoperability is often lower than with Bluetooth or passive RFID.	Common implementations use sub-GHz or 2.4 GHz radio bands. Exact frequency and channel plan must be verified for the destination country.	Replaceable or sealed battery. Typical service life is approximately 1–5 years, depending on beacon interval, sensor activity, and operating temperature.	Manufacturing plants, returnable transport items, vehicle identification, personnel safety, and long-range zone monitoring.	CE / RED FCC UKCA RoHS REACH Battery transport compliance	Verify the exact radio protocol, channel allocation, antenna gain, duty-cycle limits, reader interoperability, and availability of replacement batteries.
Passive UHF RFID Label or Hard Tag	Passive backscatter technology based on EPCglobal Class 1 Gen 2 / ISO 18000-63 in compatible systems.	Primarily provides portal, shelf, doorway, or zone identification rather than continuous precise coordinates. Read distance is often several meters and depends on reader power, antenna design, tag orientation, and material.	Requires UHF RFID readers and antennas supporting the applicable EPC / ISO air interface. Regional frequency profiles must match the reader configuration.	Regional UHF RFID operation generally falls within approximately 860–960 MHz, with different sub-bands and power limits across jurisdictions.	Battery-free. Tag life is normally limited by mechanical durability, adhesive performance, environmental exposure, and application conditions.	Inventory control, supply-chain visibility, asset check-in and check-out, pallet tracking, warehouse portals, and retail item identification.	EPC Class 1 Gen 2 ISO 18000-63 CE / RED for readers FCC for readers RoHS REACH	Select the correct regional UHF frequency profile, validate performance on metal and liquids, confirm reader power limits, test portal read rates, and check label adhesive or enclosure durability.
Passive HF RFID Tag	Near-field inductive coupling, commonly compliant with ISO/IEC 15693 or ISO/IEC 14443 depending on the application.	Usually near-contact to approximately 1 m, depending on tag size, reader antenna, operating standard, and environmental conditions.	Requires an HF reader supporting the same ISO standard and memory or security features. NFC-compatible tags may work with supported mobile devices, but not every tag supports every NFC function.	13.56 MHz ISM band.	Battery-free. Expected service life is determined mainly by materials, attachment method, and environmental durability.	Access control, equipment identification, library systems, ticketing, maintenance records, and close-range asset verification.	ISO/IEC 15693 or ISO/IEC 14443 NFC Forum requirements where applicable RoHS REACH	Confirm the exact HF protocol, smartphone compatibility, required memory capacity, encryption features, reader certification, and resistance to chemicals or sterilization processes.
LF RFID Animal or Industrial Tag	Low-frequency inductive RFID, commonly based on application-specific identification standards such as ISO 11784/11785 for animal identification.	Short-range identification, commonly from a few centimeters to approximately 1 m, depending on the reader coil, tag format, and installation.	Requires an LF reader using the same modulation, coding, and identification format. It is generally not interchangeable with HF or UHF RFID infrastructure.	Common LF systems operate around 125 kHz or 134.2 kHz. Exact permitted use and application requirements should be checked locally.	Usually battery-free for injectable, glass-encapsulated, or industrial tags. Durable versions can support long service periods when correctly installed.	Livestock identification, industrial component verification, access applications, and environments where metal or liquids limit higher-frequency performance.	ISO 11784/11785 where applicable RoHS REACH Local product and animal-health rules	Verify the destination market's animal-identification or industry requirements, reader format compatibility, encapsulation material, sterilization needs, and local import or veterinary documentation.
Cellular IoT GNSS Tag	GNSS positioning combined with LTE-M, NB-IoT, or other cellular data connectivity.	GNSS outdoor accuracy is commonly about 3–10 m under favorable conditions. Indoor performance may be unavailable or significantly degraded without supplementary sensors.	Requires support from destination-country cellular bands, carrier roaming or local SIM service, APN configuration, and a compatible cloud platform.	GNSS reception uses satellite navigation bands; cellular frequencies vary by LTE region and operator.	Rechargeable battery, often lasting weeks to several months depending on reporting interval, network coverage, motion detection, and GNSS usage.	Vehicle and container tracking, outdoor equipment, cross-border logistics, remote assets, and applications requiring wide-area connectivity.	CE / RED FCC UKCA PTCRB or operator acceptance where required RoHS REACH UN 38.3	Confirm LTE band support, network shutdown plans, SIM and roaming terms, data privacy obligations, eSIM provisioning, GNSS antenna performance, and battery shipping documentation.
Hybrid Multi-Technology Tag	Combines two or more technologies, such as UWB plus Bluetooth LE, BLE plus NFC, or RFID plus sensor connectivity.	Can provide high-accuracy indoor positioning and lower-power or wide-area fallback. Actual performance depends on each integrated radio and the location platform.	Requires interoperability across all included readers, gateways, software interfaces, firmware versions, and device-management systems.	Uses the frequency bands of each integrated technology. Every radio must be approved for the destination market.	Usually rechargeable or replaceable battery. Battery life is governed by the most energy-intensive operating mode.	Global logistics, hospitals, smart factories, campus operations, high-value assets, and deployments requiring indoor and outdoor continuity.	CE / RED FCC UKCA Bluetooth SIG where applicable RoHS REACH UN 38.3	Request a complete radio test report for every wireless function, verify simultaneous-transmission limits, confirm firmware update procedures, assess cybersecurity, and validate roaming or regional configuration before mass deployment.
