Let's keep a close 👀eye on the Notice issued by Ministry of Industry and Information Technology？ The Notice requires that wireless LAN equipment manufactured or imported for sale or use in China that adopts IEEE 802.11be technology shall comply with the requirements set forth in the Notice on Strengthening & Standardizing the Radio Management of 2400 MHz, 5100 MHz, and 5800 MHz bands (MIIT 2021 No. 129), and meet and meet three new test requirements for Multi-Link Operation (MLO) characteristics, Multi-Resource Unit (MRU) spectrum templates, and Error Vector Magnitude (EVM). #wireless #LAN #radio #China

Regulators have issued updates over the past week including a public consultation on the newly drafted Circular to amend and supplement of existing Circular 04/2023/TT-BTTTT in Vietnam and an announcement outlining the technical requirements and test methods for Wireless LAN devices that support IEEE 802.11be in China. #RegulatoryChange #RegulatoryAffairs #PCregupdate #TypeApproval #GlobalMarketAccess #Compliance Kiwa UK

📢 MSIT Revises Wireless Equipment Technical Standards Notice to Facilitate Domestic Introduction of Wi-Fi 7   In an effort to facilitate the domestic adoption of Wi-Fi 7, the Ministry of Science and ICT (MSIT) has announced plans to revise the notification regarding the technical standards for unlicensed wireless devices. Public comments will be accepted until May 20, 2024, after which the notification will be revised and implemented.   - The occupied frequency bandwidth of a specific low-power wireless device for wireless connectivity systems, including the 6 GHz band WLAN, is expanded from 160 MHz to 320 MHz.   - The radiated power of certain low-power wireless devices for wireless connectivity systems, including 6 GHz band WLANs, increases from 250 mW to 500 mW as the occupied frequency bandwidth increases.

LAC,RAC &TAC....... ? LAC :- is used in GSM and UMTS networks to identify location areas. RAC:-is a more general term for codes used in network routing but isn't specifically defined in mobile network standards as LAC or TAC. TAC:- is used in LTE networks to identify tracking areas, playing a similar role to LAC but in newer network technologies.

In Canada, the available channel width for WiFi networks typically adheres to the regulations set forth by #IndustryCanada, which oversees spectrum allocation and usage in the country. The #5GHz band offers more channel options and typically supports wider channel widths compared to the #2.4GHz band. In Canada, the 5 GHz band can include channels from 36 to 165, with additional Dynamic Frequency Selection (DFS) channels available. Common channel widths used in the 5 GHz band include 20 MHz, 40 MHz, 80 MHz, and even 160 MHz in some cases. However, the use of wider channel widths may be subject to regulatory restrictions and DFS requirements to mitigate interference with radar systems. It's important for users and network administrators to be aware of local regulations and guidelines when configuring WiFi networks to ensure compliance with spectrum regulations and optimal performance in Canada. #BitronTech #WiFiInnovation #DFSIntegration #WirelessNetworking #WiFiOptimization
