1 Scope

GB/T 46803.2-2025 is the Chinese national standard covering the data link layer above that physical layer - the framing and addressing, the channel access for thousands of devices that wake rarely, the acknowledgement and retry, and the security of a link that must cost almost no energy. At 97,500 words it is the largest 2025 standard published so far in this catalogue. Part 2, first edition. It was issued on 2 December 2025 and has been in force since 1 July 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the data link layer technical requirements and test methods for low-power wireless communication networks based on polar codes. This document applies to the development of low-power wireless communication network devices based on polar codes.
