Tanzania - Inductive Applications

Regulatory Summary

Inductive applications, including wireless power transfer and RFID systems, are regulated by the Tanzania Communications Regulatory Authority (TCRA) under the Short Range Device (SRD) regulations issued in June 2024.

Key Regulatory Documents

  • Tanzania National Frequency Allocation Plan (NFAP) (June 2024) - Superseding framework
  • Technical Specifications for Short Range Devices (TCRA/TS015) (June 2024)

360 kHz Wireless Charging Analysis

✅ STATUS: PERMITTED

  • Frequency Band: Falls within NFAP 148.5 - 5000 kHz allocation for inductive applications
  • Power Limit: -15 dBμA/m at 10m
  • Licensing: License-exempt SRD basis under NFAP framework
  • Primary Service Constraint: Must not cause harmful interference to RADIONAVIGATION services (315-415 kHz band)
  • Regulatory Framework: NFAP  and  SRD regulation (june 2024)


Regulatory Requirements

Authorization Framework

  • General Principle: Use of radio frequency in Tanzania requires authorization from TCRA
  • SRD Exception: SRDs generally operate on a license-exempt basis when complying with technical specifications
  • NFAP Compliance: Equipment must operate within NFAP allocation parameters
  • Type Approval: TCRA mandates type approval for communication equipment used in Tanzania

Technical Constraints

  1. Power Limitations: Strict magnetic field strength limits apply across all frequency bands
  2. Interference Protection: SRDs must operate on Non-Interference Non-Protection (NINP) basis
  3. Secondary Basis: SRDs cannot claim protection from interference caused by primary services
  4. RADIONAVIGATION Protection: Special attention required for 315-415 kHz band

ISM Band Considerations

For frequencies in ISM bands (6.78 MHz, 13.56 MHz, and 27 MHz):

  • Special Authorization: Required by TCRA in coordination with other administrations
  • Interference Acceptance: Must accept harmful interference from ISM applications
  • Higher Power Limits: 42-60 dBμA/m at 10m depending on specific application

Commercial Implementation Guidelines

Wireless Charging (360 kHz)

⚠️ Technical Challenge: The -15 dBμA/m at 10m power limit is extremely restrictive and may limit practical commercial wireless charging applications. Technical feasibility assessment recommended before commercial deployment.

RFID Applications

  • Low frequency RFID (119-135 kHz): Permitted with spectrum mask compliance per EN 300 330
  • Medium frequency RFID (400-600 kHz): RFID-specific allocation with -8 dBμA/m limit
  • High frequency RFID (13.56 MHz): Higher power limits available (60 dBμA/m at 10m for RFID/EAS)
  • UHF RFID: Separate regulations apply (see Tanzania RFID article)

Recent Regulatory Updates

  • June 2024: TCRA issued comprehensive Tanzania National Frequency Allocation Plan
  • June 2024: Updated Technical Specifications for Short Range Devices published
  • Regulatory Hierarchy: NFAP established as superseding framework for frequency allocations
  • Technology Focus: Specifications revised for spectrum efficiency and interference immunity

General Allocation Ranges (NFAP)

  • 9 kHz - 148.5 kHz: Inductive applications explicitly mentioned with specific SRD band definitions
  • 148.5 kHz - 5000 kHz: Inductive applications mentioned in portions of this range under NFAP

Regional Context

Tanzania follows ITU Region 1 frequency coordination frameworks and participates in East African Community (EAC) telecommunications harmonization initiatives affecting spectrum management.
