A large number of engineers and developers involved in the Internet of Things (IOT) services, and create a lot of equipment. With the occurrence of this situation, developers began to consider the degree of congestion of these devices in space and frequency. For all engineers have been necessary, consider creating some of the following three examples of devices:
Power efficiency
Any device requires power. Consumption and Tx / Rx parameters
"How much is consumed, how much waste" is the designer must pay attention to the problem
The result will be considering the power compact unit
Cost efficiency
Not only saves power consumption
The lower number of components, the lower cost
Extend equipment life, and maintaining low temperatures, lower costs
Reliability efficiency
Since the effective power management, networking equipment longer life
Simple centralized communication data results in a short time Tx / Rx activities
Communication errors and omissions will remain intact network of security and health
These three things are planned designers for their products things implemented, will allow the creation and spread of so-called LPWAN (low-power wide area network) products, such as NB-IoT module . We focused solely on things designers and developers to present the new protocol to deal with these billions of devices being studied. The reason LPWAN integrated into the Internet of Things is possible to ensure the use of data bandwidth, speed and efficiency, so as to maintain a safe and reliable network.
LPWAN technology
Some companies are being set up and alliances to create protocols needed to create LPWAN. Like Sigfox company has made some significant progress, the company is to enable a protocol, the protocol focuses on all devices work together in short packets. Another group of companies formed an alliance called Lora alliance, it is also moving forward. Lora Union are also developing their own protocol, called LoRaWAN. Another company called Link Labs have developed a protocol called the Symphony Link. Finally, a company called nWave also have similar programs, such as Sigfox, it has made progress in the field of LPWAN. Therefore, Sigfox example, its agreement to get so much attention because it is the overall strategy, while cost savings, combined with efficient power-things device. Sigfox focus on the work of the packets in 200Khz bandwidth of the field, you can let the world billions of Things devices work together seamlessly.
