With the approach of 5G commercial timetable, Huawei, ZTE, Samsung, Ericsson and Nokia and other communications equipment vendors are vying for the cake in the 5G market. The White Paper on 5G Economic and Social Impacts issued by China’s Xintong Institute predicts that by 2020, 5G will indirectly drive GDP growth by more than 419 billion yuan; by 2030, 5G-driven direct output and indirect output will reach 6.3 trillion yuan respectively. And 10.6 trillion yuan. Recently, at the 9th Global Mobile Broadband Forum, Huawei announced that the company has been recognized by nearly 50 telecom operators around the world and has shipped 10,000 5G base stations, mainly to Europe, the Middle East and other markets. Huawei's 5G commercial contract has been signed 22, reaching half of the global share. In the field of 4G mobile communications, Huawei already has great advantages. The data shows that Huawei's 4G technology patents reached 603, ranking first, followed by Nokia, Erics

Today’s wireless routers are widely used, including TVs, mobile phones, computers and other household appliances. So how to set up wifi passwords to ensure that they are not leaked? Richerlink researched from the router itself, showing you how to set the  wireless router   password. There are two major password protections on the wireless router: (1) Wireless wifi password;  (2) Administrator password. 1.How to set the wireless router wifi password characters (1).Avoid using birthday or pure numbers to set up a wireless wifi password, such a very regular number, it is easy to be cracked. (2).When setting the wifi password, try to set the wifi password more complicated, and do not use four or six common password digits. You can add a space character to the password to increase the difficulty of cracking. (3). WIFI master key and other software with wifi sharing function, in the use of mobile phones, try to avoid sharing these wireless network passwords. (4).The wifi f

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 asynchronous ALOHA-based
