868MHz - 915MHz, supporting frequency - hopping communication.
Communication Protocol
Adopting GFSK radio frequency (RF) communication technology and an independent wake - up communication mechanism. This ensures low power consumption and high load capacity for communication: a single tag is woken up for data transmission, which guarantees a clean and reliable communication channel without interfering with other tag devices. In this way, both high load capacity and low power consumption as well as real - time performance can be achieved.
Transmission Distance
The communication radius is 30 meters, and there is no directionality. Deploying one base station every 30 meters ensures communication redundancy and reliability.
Penetrability
The radio frequency has strong penetration and is less affected by obstacles, making it suitable for application scenarios in warehouses with dense shelves and goods.
Power Consumption
The receiving standby power consumption is low. In typical applications, the average standby power consumption is less than 40μA. In scenarios where tags are operated 10 - 20 times a day, a service life of 1 - 2 years can be achieved. Moreover, parameters can be adjusted according to different usage scenarios to meet the requirements of either real - time performance or lower power consumption.
Scalability
Tags adopt a passive wake - up operation mode, so there is no limit on the number of tags in the warehouse. The number of tags can be flexibly increased or decreased, and the system supports an unlimited number of tags.
