Introduction

According to the Ministry of Industry and Information Technology's document "Notification on Issuing Technical Requirements for < Micropower (Short Range) Radio Equipment>" [2005] 423) to use the 174MHz~216MHz, 407MHz~425MHz, and 608MHz~630MHz frequency bands Biomedical telemetry equipment, ie radio transmitting equipment for transmitting signals for measuring physiological phenomena in humans or animals, limited to hospital or medical research The use within the organization shall not interfere with the radio astronomy business. This standard has established anti-interference in the frequency bands of 174MHz~216MHz, 407MHz~425MHz and 608MHz~630MHz. Low-speed wireless personal area network physical layer specification, MAC layer specification see GB/T 15629.15-2010. Telematics between information technology systems and Information exchange LAN and MAN specific requirements Anti-jamming low-speed wireless personal area network physical layer specification

1 Scope

This standard specifies the anti-interference of 174MHz~216MHz, 407MHz~425MHz and 608MHz~630MHz frequency bands Low-speed wireless personal area network physical layer specifications, including physical layer general requirements, O-QPSK, and GFSK physical layer requirements. This standard applies to operation in the 174MHz ~ 216MHz, 407MHz ~ 425MHz and 608MHz ~ 630MHz frequency band Development and design of biomedical telemetry equipment.
