The new generation of Internet of Things (IoT) standard - Weightless-N version 1.0 was officially released. The Weightless Special Interest Group (SIG) launched a series of developments for the Weightless-N standard last year. The Weightless 1.0 version of the architecture was confirmed to be based on low-power, wide-area network coverage, using sub-GHz spectrum. And ultra narrow band (Ultra Narrow Band) technology, can meet more IoT applications.
Weightless SIG CEO William Webb said that the Weightless-N standard is designed to help developers build better products, help them reduce development costs, increase choices, reduce risk and promote innovation, so that the Weightless-N standard can finally To the popularity.
Weightless-N has good signal transmission characteristics, and it can transmit signals to a few kilometers away even in a city with a complex signal. Thanks to its extremely low power consumption, this technology extends the life of traditional small batteries and advanced design batteries, reducing terminal hardware and network costs.
It is known that Weightless-N is a differential binary phase shift keying (DBPSK) digital modulation (ModulaTIon) scheme, which can support the transmission of narrow frequency band hopping (Frequency Hopping) algorithm, reduce interference and improve security. In addition, the specification also provides encryption and implicit authentication, using a Secure Key mechanism to encode and transmit messages via the 128-bit Advanced Encryption Standard (AES) algorithm.
In addition, Weightless-N supports mobile network auto-routing (RouTIng), which can transmit terminal messages to the correct destination. For example, multiple networks and typical operations of different companies can be placed in the same location (Co -located) Each base station will seek a central database to determine which network terminals have been recorded in order to decode and route the data in sequence.
Compared to other proprietary low-power wide area network (LPWAN) technologies, Weightless enables a competitive, free and fair market and allows developers to use resources from specific vendors or network service providers. Every company can use Weightless technology to develop low-cost base stations and end equipment for free; in general, Weightless can create end equipment for less than $2, with a bill of materials (BOM) costing less than $3,000. station.
Jonathan Wiggin, NWave's CEO and core member of the Weightless SIG, points out that in this competitive environment, Weightless is an open standard that leads developers toward lower cost, higher security, less risk and continuous innovation. Provide an excellent solution for developers and end users.
