What Frequencies Do Tour Guide Systems Operate On And Where Can You Use Them Licence-Free?
Tour guide systems are essential tools for delivering clear, uninterrupted communication in group settings from museum tours and factory visits to multilingual conferences and outdoor excursions. But one of the most important considerations when choosing a system is frequency compliance. Understanding which frequencies are licence-free and where they can be used legally is crucial for smooth operation across different regions.
Common Frequencies Used in Tour Guide Systems
Tour guide systems typically operate on short-range radio frequencies that are either licence-free or require minimal regulation. The most commonly used frequency bands include:
2.4 GHz Band
• Frequency Range: 2.4 GHz – 2.4835 GHz
• Licence Requirement: Licence-free worldwide
• Examples: Williams AV Digi-Wave, AXIWI AT-320M, Tourtalk TT 100
• Usage: For international travel
DECT Band
• Frequency Range: 1.8 – 1.9 GHz
• Licence Requirement: Licence-free in UK and EU
• Examples: Televic Unite, Listen Technologies ListenTALK
• Usage: For secure interference-free communication and automatic frequency management.
UHF Band
863 – 865 MHz (UK Channel 70)
• Licence Requirement: Licence-free in the UK and EU
• Examples: Sennheiser 2020-D, Contacta RF-865, AXIWI AT-350, Tourtalk TT 21, Tourtalk TT 40, Tourtalk TT 200, Tourtalk TT 300
823 - 832 MHz (UK Channel 65/66)
• Licence Requirement: Licence-required in the UK some EU countries
• Licence-free: In most EU countries
• Examples: Tourtalk TT 21, Tourtalk TT 200, Tourtalk TT 300
606 – 614 MHz (UK Channel 38)
• Licence Requirement: Licence-required in the UK and most EU countries
• Examples: JTS TG-10
• Usage: For excellent sound quality and robust signals that can accommodate multiple systems simultaneously without degradation.
Most tour guide systems that have a tuning range that includes 832 – 832 MHz can also operate on (the licence-free) 863 – 865 MHz. Generally, users will choose channels that utilize 863 – 865 MHz first which will typically enable four separate tour groups to operate together without any annual costs. If more groups are required, then the channels that operate 823-832MHz can be used. A frequency table is supplied with UHF tour guide systems that show which channels are allocated to specific frequencies.
Regional Licensing Overview
United Kingdom
• Licence-Free Bands: 2.4 GHz, DECT (1.8–1.9 GHz), 863–865 MHz
• Regulator: Ofcom
Note: To operate on 823-832 MHz and 606-614 MHz a licence is required from Ofcom. This is very straightforward to purchase, and the cost is in the region of £75 a year.
European Union
• Licence-Free Bands: 2.4 GHz, DECT (1.8–1.9 GHz), 863–865 MHz, 823-832 MHz (in some countries)
• Regulator: Country specific
Note: Generally cross-border use is allowed under EU harmonisation rules however some countries have different regulations.
Rest of World
• Licence-Free Bands: 2.4 GHz
• Regulator: Country specific
Note: It is the operator’s responsibility to verify with local communications authorities for country-specific rules.

Why Wireless Frequencies Matter
Operating on the correct frequencies ensures:
• Hassle-free setup across borders
• No hidden costs or delays due to licensing
• Less risk of interference from other systems
• Compliance with international standards
Choosing the Right System
When selecting a tour guide system, consider:
• Where you’ll be operating (domestic or international)
• Group size and environment (indoor, outdoor, noisy settings)
• Battery life and range
• Multi-language support (dual transmitters, interpreter features)
Whether you're guiding a cultural tour in London or managing a multilingual event in Paris, choosing a frequency-compliant tour guide system is key to delivering a seamless experience.
