Recently, the concept of passive IoT has been brought on fire by a group of companies making Bluetooth, UWB, and even 5G, because it has a larger imagination space for the number of connections than active IoT.
。
The industry's expectation for the connection of passive IoT is hundreds of billions. As a kind of passive IoT technology, RFID has been widely used already.
Compared with other wireless technologies, passive RFID can transmit farther, and RFID is the best passive IoT technology;
The cost advantage of RFID is obvious. RFID is the answer to the solutions of future hundreds of billions of low-cost IoT connection.
Of course, RFID technology also has its limitations. For example, it can only store and transmit a small amount of data, and UHF RFID cannot interact with mobile phones. ?…
Different scenarios require different solutions, and other passive IoT technologies will also find their own application space.
