Why do you want to aggregate on Bluetooth?

In the middle of last month, the SIG released the Bluetooth specification, which indicates something bigger than the new wireless specification. This initiative has officially established the latest major developments in network skills, which will increase its use in the Internet of Things. Coverage on home and networked commercial devices is expanding, with more than half of network network standards or protocols.

In 2004, the Zigbee Alliance first released a low-power network, and now you can find it in smart home solutions, including networked lighting products from companies such as Philips and Osram, and smart meters that are widely dominated in the US and UK. The second-generation agreement, Thread, launched in 2015, was a great success when it was launched in 2015 with Nest and Google as founding members. Until this year, Bluetooth has connected more than 8.2 billion devices, and by 2021, Bluetooth devices will be used for 60% of wireless devices.

There are also many different versions of Bluetooth, from classic "one-to-one" communication, to continuous voice/audio streaming or device-to-device data transmission, to "one-to-many" broadcasting, and the latest is large-scale networking. Applications grow "many-to-many" communications such as smart homes, building automation and smart lighting .

Zigbee and threads pass a routing skill to pass information. In this skill, a message jumps from one node to another to reach the final destination. However, the Bluetooth network uses a "managed flooding" skill in which each device in the network sends information to other nodes. Although it can be either easier or more flexible in terms of simpler application methods, it will also increase the latency and power consumption of some large-scale networks. While the advantages of arguing that zigbee/thread routing and Bluetooth networking skills are humorous, what are the benefits?

Extended range : In a star network topology, all devices must be located within the radio range of the central device. Our mobile phones and Wi-Fi experience this: our calls can be or will be lost, or when we are out of range, our Wi-Fi connection is lost. For networks with other device routing messages, they can or end the communication even when they are not in range of each other.

Self-healing network : Many early home wireless technologies supported multi-hop performance, but network settings were manually set up during network assembly. Radio conditions and the environment change over time, and the network passes through multiple paths between the source and destination to provide autonomous self-healing.

Enhanced network reliability : Fully planned and well-functioning network network provisioning reliability as it can or better bypass error or intermittent connections.

Scalability : As the network grows to hundreds of devices, having a single central connection point can or can be an achievement. Building a larger, scalable network with an application network can or enable you to enhance your network's propagation radio load.

Improve energy efficiency and battery life : For devices that are frequently transmitted, transmission power is an important component of battery life. The network enables these devices to reliably handle communication achievements with or with lower transmit power and powered routers.

It remains to be seen how the Bluetooth network will perform in a large-scale network in the real world. We need to see more Bluetooth domain realities to assess its feasibility, reliability, scalability and performance. Mutual control will become a really important thing in the network. To date, Bluetooth-enabled products are often point-to-point solution planning, with one vendor controlling the application at both ends. However, in the real world of web application, we will see multiple products from different manufacturers that need to be controlled with seamless message routing and security end.
