Things common technical classification and its corresponding frequency

Huge business needs, with a very significant vertical characteristics of the industry is currently one of the popular concept of the market。 The business scenario may be subdivided into a fixed or slow wireless data access (local IOT), a mobile wireless data access (moving things), ubiquitous wireless data access (WAN low power IOT) three cases。 If the transmission distance according to divide wireless technology, our common networking technology and telecommunications can be divided into short-range communication networking technology, broadly categorized as follows: Category LORA things, China Union LORA application (CLAA) recommended 470?510MHz。
The main frequency range of other areas in the following table: LoRaWAN area frequency range Europe 863to870 North America 902to928NB, Internet of things, the world of mainstream bands are 900MHz and 800MHz。
China Telecom will deploy the first choice as the 800MHz band of NB- of IoT, China Unicom will choose to deploy IoT NB- of 900MHz, and China Mobile may Chonggeng existing 900MHz band。 IoT main frequency NB- of the globe in the following table: Sigfox, Europe, Middle East: 868 (ETSI300220), North America: to 902MHz (FCCpart15), South America / Australia / New Zealand: 920MHz (ANATEL506, AS / NZS4268)。
SIGFOX area Frequency range (MHz) in North America, Europe 863to870 902to928Weightless, as an open standard LPWAN wireless technology, it works in the whole of unlicensed sub-GHz of ISM / SRD band can be deployed worldwide: 169/433/470/780 / 868/915 / 923MHz。 The Wi-Fi and Bluetooth support for Bluetooth, commonly deployed in the 2.Common frequency band, WIFI system and the other frequency of 4GHz ISM may refer to the following table: Bluetooth 2400to2483.5 (MHz) of the NFC, is reported that the Ministry will be released on 13.NFC technology is standard 56MHz。 NFC and other parts of the band reference the following table: NFC, RFID125kHzto134kHz6.7MHz13.56MHz (NFC) 27MHz433MHz865MHzto868MHz (Europe) 902MHzto928MHz (North America) 5.8GHz2.45GHz24.125GHzZ wave, the operating frequency is 868 in China.40MHz, comply with ETSI / EN300220 standard。
ZigBee theme, ISA100.11a to IEEE802 standards specifications are.15.4 be expanded, based on the general IEEE802.15.The device 4 with a frequency of 868/915 / 2400MHz of。
Specific reference to the following frequency: The ZigBee / thread / 6LoWPAN of (an IEEE 802.15.4) 169.4to169.475MHz250to750MHz779to787MHz863to879MHz896to960MHz1427to1518MHz2360to2483.5MHz3244to4742MHz5944to10234MHzZigBee3.0, thread, 6LoWPAN2360to2483.These are the days 5MHz vertical detection (Skylabs) combined with the current common networking technology and frequency band information corresponding public data collated, which may inevitably be missed or even mistakes, and therefore the information contained herein is for reference only。 Allocation of frequency bands specific countries with the latest information on ITU prevail。
