Referring to the short-range wireless communication technology in the Internet of Things, many people may think of Bluetooth and WiFi in the first place. But in fact, other technologies, including Zigbee , are growing at a faster rate and quickly occupying the market. Since the beginning of the past few years, the domestic market has made a significant shift in the development attitude of Zigbee technology. More and more Chinese manufacturers have joined the Zigbee Alliance, including WULIAN, Huawei, and the United States, all of which have become members of the Zigbee Alliance. Zigbee technology development accelerates China's market attitude has changed significantly. The global Zigbee activation equipment market 2016-2020 report predicts that the global Zigbee activation equipment market will achieve a CAGR of 29.73% during 2016-2020. At the same time, more and more Chinese companies are joining the Zigbee Alliance. For the Zigbee Alliance, this is a big change, because in ...

The difference between NB-IOT and Lora

图片
NB-IOT and Lora Introduction The wireless technologies of the  Internet of Things  are mainly divided into two categories: (1) One type is short-distance communication technology such as Zigbee, Wifi, Bluetooth, Z-wave; (2) The other type is LPWAN, which is a low-power wide-area network. LPWAN can be divided into two categories:  LoRa , SigFox, etc., which work on unlicensed spectrum, and 3GPP, which work in licensed spectrum. 2/3/4G cellular communication technologies such as EC-GSM, LTE Cat-m, NB-IoT, etc. The difference between NB-IoT and Lora 1. Frequency bands, quality of service and costs.  LoRa works in unlicensed frequency bands below 1Ghz, and does not require additional charges when applied. NB-IoT and cellular communication using licensed bands below 1 GHz are authorized and chargeable. 2. Battery life.  There are two important factors to consider regarding battery life, the current consumption of the node and the protocol content. LoRa is an a...

Can you distinguish between the light cats, routers, TV boxes in the home network?

Nowadays, the Internet has entered thousands of households, and the Internet has become an indispensable thing in life. Moreover, with the continuous improvement of the network speed and the development of “light into copper retreat”, most new residential communities and network users have now achieved fiber-to-the-home. In this way, the average network user will have several boxes at home, such as light cats, routers, network TV boxes, etc. Sometimes there is a failure, the user does not know how to distinguish, how to describe them, can not quickly and correctly declare obstacle. 1.Light cat Light cat is a common name. The modem from the early dial-up era, commonly known as the cat, is called a modem, and turns a digital signal into a device that transmits analog signals over a telephone line. After entering the era of optical network, the optical signal transmitted by the optical fiber arrives at home, and a device needs to be converted into an electrical signal to communicate wi...
