The technology development today, not only is the world of the Internet, but also the world of the IOT. The so-called “IOT” is the Internet where everything is connected, and all smart devices can realize intelligent and convenient interaction through the network, bringing users a better experience. Therefore, some people believe that the IOT in the next decade will be one of the most lively track.
Smart lock as one of the smart products gradually “fire up” in recent years, the same can not be separated from the Internet of things. Only through the way of networking, so that users can have experience of “door lock dynamic real-time monitoring” “real-time knowing of the family in and out of the home” “door lock low battery warning” “anti-pry alarm” and other functions.
However, most of the previous smart locks are networked through ZigBee, Z-ware, Bluetooth, etc., the biggest pain point of these communication methods is the need for a gateway to connect the door lock to the router, in order to connect with the user’s cell phone, so as to achieve the above-mentioned various networking functions, but the biggest feature of these communication methods is that the bandwidth is not large enough to carry out remote visualization and other functions. 
Nb-lot technology is based on cellular narrowband Internet of Things has become an important branch of the Internet of Everything network, that is, through the operator’s cellular network can achieve IoT functions, thus eliminating the need for a gateway.
The biggest feature of Nb-lot network is that it can connect countless terminals, and the management can manage dozens, or even hundreds, or thousands of smart locks through a back-end, and the smart locks of this networking method are mainly used in the field of public housing, short and long term rental apartments, and home locks are not used. And Nb-lot network by the operator network coverage, public housing and other places have Nb-lot network coverage, because the device can apply to the operator network base station coverage. Although, ZigBee, Z-wave and other communication methods can also manage public housing, long and short term rental apartments smart lock, but Nb-lot network has a late-stage advantage, has gradually become the main networking method of public housing smart lock.
Nb-lot network and ZigBee, Z-wave and other communication methods can not carry too much bandwidth, and today’s smart locks have tended to visualize, which means that to achieve remote visual intercom, remote monitoring and other visual functions, these communication methods can not meet. Therefore, only Wi-Fi can carry the bandwidth required for visualization functions.
For this reason, in the context of the increasing popularity of visual smart lock, Wi-Fi direct connection has become the main way of networking smart lock products, ZigBee, Z-wave and other communication methods in the field of smart locks will be less and less, the gateway will also become less and less. And the prevalence of Wi-Fi direct connection, in addition to the demand for product functionality upgrades, another reason is that the power consumption of Wi-Fi has been reduced, so the choice of Wi-Fi as a communication method manufacturers will also be more and more.
So there are some reason’s why nowadays Smart Door Locks Fewer Use Gateways ?
Ⅰ.The trend towards fewer smart door locks using gateways is the increasing popularity of Wi-Fi-based smart locks. Many newer smart door locks are equipped with Wi-Fi connectivity, allowing them to connect directly to the internet and bypass the need for a gateway. This makes it easier and more convenient for users to set up and control their locks, as they don’t need to worry about setting up a separate gateway device.
Ⅱ. The trend towards fewer smart door locks using gateways is the increasing availability of smart home platforms and voice assistants. Many smart home platforms, such as Google Home and Amazon Alexa, offer integrated support for a wide range of smart devices, including smart door locks. This means that users can control their locks using their voice or a smartphone app, without the need for a separate gateway.
Ⅲ. Increasing popularity of home security systems with built-in smart lock support. Many modern home security systems offer integration with smart locks, allowing users to control and monitor their locks directly from the security system app. This eliminates the need for a separate gateway and streamlines the user experience.
Ⅳ. The trend towards fewer smart door locks using gateways may also be due to the increasing simplicity and reliability of smart lock technology. Many newer smart locks are designed to be easy to install and use, with minimal setup required. This means that users can simply install the lock and start using it right away, without the need for a separate gateway or other complex setup steps.
So, the question arises: Wi-Fi gradually become the mainstream of smart lock networking, the gateway will exit the smart lock history stage?
