This information note serves to help consumers for an informed choice of legitimate Wi-Fi devices for use in Hong Kong.
Wi-Fi devices are conventionally operating in the 2.4 GHz and 5 GHz bands1 based on the IEEE 802.11 series of standards. In particular, those in compliance with the IEEE 802.11n, 802.11ac and 802.11ax standards are commonly known as Wi-Fi 4, Wi-Fi 5 and Wi-Fi 6 devices respectively. Since 2022, new classes of Wi-Fi devices, namely Wi-Fi 6E and Wi-Fi 7, have emerged in the market. Wi-Fi 6E is based on the IEEE 802.11ax standard whereas Wi-Fi 7 is based on the IEEE 802.11be standard. They are both capable of operating in a new frequency band of 5.925 – 7.125 GHz ("the 6 GHz band") in addition to the conventional 2.4 GHz and 5 GHz bands. In this regard, consumers should note that only those Wi-Fi 6E and Wi-Fi 7 devices operating within the lower part of the 6 GHz band (i.e. the 5.925 – 6.425 GHz band, hereinafter referred to as "the designated 6 GHz band") are permitted for use in Hong Kong.
Persons who are in possession, use and sale of Wi-Fi devices operating in the 2.4 GHz and 5 GHz bands are exempted from obtaining a telecommunications licence, subject to meeting the stipulated requirements under the law2. Pursuant to the Class Licence for 6 GHz Device (“the Device Class Licence”) created by the Communications Authority (“CA”), any person might also possess, use and sell Wi-Fi 6E and Wi-Fi 7 devices operating within the designated 6 GHz band, subject to fulfilment of the conditions of the Device Class Licence. As far as users are concerned, the Device Class Licence for Wi-Fi 6E and Wi-Fi 7 devices and licence-exemption for Wi-Fi devices achieve the same effect, i.e. users do not need to individually apply for a telecommunications licence and no licence fee would be incurred, for use of compliant Wi-Fi devices. The licensing requirements for Wi-Fi devices are summarised below -
2.4 GHz band | 5 GHz bands | 5.925 – 6.425 GHz (the designated 6 GHz band) |
6.425 – 7.125 GHz | |
---|---|---|---|---|
Wi-Fi 4 | ||||
Wi-Fi 5 | ||||
Wi-Fi 6 | ||||
Wi-Fi 6E | ||||

Table 1: Licensing requirements of Wi-Fi devices in Hong Kong
At present, some economies, including Canada and the United States, allow Wi-Fi 6E and Wi-Fi 7 devices to operate in the entire 6 GHz band rather than limited to operate within the designated 6 GHz band. It should be noted that the CA is considering the identification of the upper part of the 6 GHz band, i.e. the 6.425 – 7.125 GHz band or parts thereof, for public mobile (including 5G) services. In this regard, Wi-Fi 6E and Wi-Fi 7 devices capable of operating outside the designated 6 GHz band, i.e. in the 6.425 – 7.125 GHz band or parts thereof, are not covered by the Device Class Licence and are not permitted for use in Hong Kong to avoid radio interference with other radiocommunications services to be licensed in the future.
Wi-Fi devices generally fall under two categories – access points3 and client devices4. All Wi-Fi devices are required to comply with the technical specifications prescribed by the CA, in particular, they cannot operate in the 6.425 – 7.125 GHz band. Under the Device Class Licence, certification of Wi-Fi 6E and Wi-Fi 7 access points against the relevant technical specifications and affixing the label prescribed by the CA (“CA label”) on certified Wi-Fi 6E and Wi-Fi 7 access points offered for sale in Hong Kong are compulsory requirements. Such requirements aim to deter the supply and use of non-compliant Wi-Fi 6E and Wi-Fi 7 access points, which may cause radio interference to other legitimate radiocommunications services in Hong Kong.
Since Wi-Fi 6E and Wi-Fi 7 client devices generally operate under the control of and at lower power than access points, they are less likely to cause radio interference to other legitimate services. Thus, certification and labelling of Wi-Fi 6E and Wi-Fi 7 client devices remains voluntary, following the same current practice for Wi-Fi 4, Wi-Fi 5 and Wi-Fi 6 devices.

Wi-Fi 4, 5, 6 devices | Voluntary | Voluntary |

Table 2: Certification and labelling requirements of Wi-Fi devices
Consumers shall purchase Wi-Fi 6E and Wi-Fi 7 access points bearing the CA label either affixed on the device or its packing as per sample below.
On the other hand, as the certification and labelling of Wi-Fi 4, Wi-Fi 5 and Wi-Fi 6 devices (both access points and client devices) as well as Wi-Fi 6E and Wi-Fi 7 client devices (not Wi-Fi 6E and Wi-Fi 7 access points) are voluntary, such devices may or may not bear the CA label. Nevertheless, consumers are encouraged to purchase Wi-Fi devices which have been certified to comply with the relevant technical specifications and may therefore be used legally in Hong Kong. A list of certified equipment models is available on the OFCA website.
Consumers are strongly reminded not to bring back Wi-Fi 6E or Wi-Fi 7 access points to Hong Kong from overseas (such as the United States and Canada), particularly those that operate in the 6.425 – 7.125 GHz band, and do not meet the technical specifications and requirements adopted in Hong Kong. Pursuant to the Telecommunications Ordinance (Cap. 106), possession or use of unauthorised radiocommunications equipment not meeting prescribed technical specifications and requirements will be liable to a maximum penalty of HK$50,000 fine and 2-year imprisonment.
Note 1: | 2.4 GHz band: 2400 – 2483.5 MHz 5 GHz band: 5150 – 5350 MHz, 5470 – 5725 MHz and 5725 – 5850 MHz |
Note 2: | Pursuant to the Telecommunications (Telecommunications Apparatus) (Exemption from Licensing) Order (Cap. 106Z). |
Note 3: | Access points include fixed Internet routers, portable Internet routers (commonly known as “pocket Wi-Fi” or “Wi-Fi eggs”), bridges, repeaters, extenders, etc. which control the operations, including the use of frequency channels, of other Wi-Fi devices connected to them. |
Note 4: | Client devices include Wi-Fi dongles, smartphones, tablets, laptop computers, smart home appliances, etc. which normally work under the control of an access point. |
