The frequency bands 2.4 GHz and 5 GHz are among the radio frequency bands that widely used in radiocommunication devices nowadays. Radio Local Area Network (RLAN) is one of the radio frequency technologies that operates in the 2.4 GHz and 5 GHz frequencies. RLAN is a Wireless Local Area Network (WLAN) that uses radio waves to connect devices wirelessly. WLAN network enables wireless data transmission within a limited area such as an office, home or school. The commonly used standard of WLAN is the IEEE 802.11 (Wi-Fi), which mostly operates in radio frequency bands 2.4 GHz and 5 GHz.
Based on current regulation in Thailand, radiocommunications equipment using radio frequency 2.4 GHz and 5 GHz is required to meet technical standard of NBTC TS 1035-2562. Therefore, in this article we will discuss all about technical standard NBTC TS 1035-2562 and its Thailand type approval requirements.
Technical standard NBTC TS 1035-2562
Technical standard of NBTC TS 1035-2562 specifies the minimum technical specifications for telecommunication and radiocommunication equipment operating in the frequency bands of 2.4 GHz and 5 GHz, both for fixed (base unit/access point) and mobile/portable units, in the following radio frequency ranges:
- 2.400 GHz – 2.500 GHz
- 5.150 GHz – 5.350 GHz
- 5.470 GHz – 5.725 GHz
- 5.725 GHz – 5.850 GHz
The technical specifications of telecommunication and radiocommunication equipment operating in the 2.4 GHz and 5 GHz frequencies are specified in the radio frequency requirements, electrical safety and radiation exposure requirements.
Radio frequency requirements
Frequency band 2.400 – 2.500 GHz
Technical standards for telecommunication and radiocommunication equipment using Broadband Wireless Access technology in the form of Radio Local Area Network (RLAN) shall be as follows:
- The output power must have an equivalent isotropically radiated power (e.i.r.p.) of not more than 100 milliwatts (mW).
- The technical characteristics of the transmitter and receiver shall comply with one of the following standards: EN 301 893 (V2.1.1) or FCC Part 15.407.
Frequency band 5.150 – 5.350 GHz
Technical standards for telecommunication and radiocommunication equipment using Broadband Wireless Access technology in the form of Radio Local Area Network (RLAN) shall be as follows:
- The output power must have an equivalent isotropically radiated power (e.i.r.p.) of not more than 0.2 watts (W).
- The technical characteristics of the transmitter and receiver shall comply with one of the following standards: EN 301 893 (V2.1.1) or FCC Part 15.407.
Frequency band 5.725 – 5.850 GHz
Technical standards for radio frequencies of telecommunication equipment and devices operating in the frequency band 5.725 – 5.850 GHz shall be specified as follows:
- The output power must have an equivalent isotropically radiated power (e.i.r.p.) of not more than 1 watt (W).
- The technical characteristics of the transmitter and receiver shall comply with one of the following requirements:
- Radiocommunication equipment using Broadband Wireless Access technology in the form of Radio Local Area Network (RLAN) must comply with one of the following standards: EN 302 502 (V2.1.1), FCC Part 15.247 or FCC Part 15.407.
- Radiocommunication equipment that uses Long Term Evolution (LTE) technology and used for private networks must comply with one of the following standards: EN 302 502 (V2.1.1), FCC Part 15.247 or FCC Part 15.407.
- Long Term Evolution (LTE) technology of radiocommunication equipment that uses International Mobile Telecommunications (IMT) must comply with one of the following standards: ETSI TS 136 104 (V13.2.0) or ETSI TS 136 101 (V13.2.0).
Safety requirements
Electrical safety requirements
Technical standards for electrical safety of telecommunication and radiocommunication equipment using 2.4 GHz and 5 GHz frequencies shall be as specified in one of the following standards: TIS 1561–2013, IEC 60950-1 or IEC 62368-1.
In the case where radiocommunication equipment using 2.4 GHz and 5 GHz frequencies is used with other products, it must show compliance with that radiocommunication equipment only or use the electrical safety standards of that product.
Radiation exposure requirements
The use of radiocommunication equipment using frequency bands 2.4 GHz and 5 GHz must comply with the requirements of the standards for human health safety from the use of radiocommunication equipment, including the criteria and measures for regulating human health safety from the use of radiocommunication equipment as determined by the National Broadcasting and Telecommunications Commission (NBTC).
NBTC certification under standard NBTC TS 1035-2562
Radiocommunication equipment using frequency bands 2.4 GHz and 5 GHz must demonstrate compliance with the standards specified in the announcement of the NBTC Office regarding the inspection and certification of standards of telecommunication equipment as follows:
| Frequency Band | NBTC Type Approval |
| 2.400 – 2.500 GHz | SDoC |
| 5.150 – 5.350 GHz | SDoC |
| 5.470 – 5.725 GHz | SDoC |
| 5.725 – 5.850 GHz | SDoC |
| Class A |
