What is 'NB - IOT+”？ — — | _nb locks _nb smart lock

The Chinese government attaches great importance to the development of the Internet of things, in June 2017, the Ministry of Industry and Information Technology released on comprehensively advancing mobile Internet of things '( NB- 物联网) Notice construction development, accelerate the requirements of the network deployment, build the NB - 物联网( Narrow Band Internet of Things, narrowband Internet of Things) Network infrastructure, by 2020, NB - IoT network to realize comprehensive coverage, ordinary, underground pipe network for indoor, transportation network application scenarios such as depth of cover, base station size to about 1. 5 million. What is a '+'? Is a narrowband Internet of things ( 窄带网络的事情,NB - 物联网) Short for agreement, NB - IoT building in cellular networks, is only about 180 KHZ bandwidth consumption, can be directly deployed in GSM network, UMTS network, or LTE, in order to reduce the deployment cost, achieve a smooth upgrade. And '+' is used as the technology of wide coverage, connection, faster, more use of operator authorization frequencies, don't need to set up base stations, the deployment of simple, low maintenance cost features combine traditional industries, all walks of life, in a new field to create a new kind of ecology. Popular, '+' is '+ various traditional industry', but this is not a simple combination, but use protocol communication technology and the Internet of things platform, in-depth integration to traditional industry, create new development. It is good, for example, in the second industrial revolution, power to make earth-shaking changes have taken place in many industries, the future will be like electricity, formed many such as NB - based IoT of smart water industry, power industry, wisdom, intelligent household industry positioning industry, agriculture and sharing new formats such as industry, and is to permeate the first and second industry. Agriculture is from automatic unattended fields permeate, save labor costs for agricultural production. Intelligent transportation is from report timing positioning data field penetration, so as to realize intelligent transportation information real-time reporting location data.
