In the field of LPWAN (low power consumption wide area network) technology, ZETA, a carrier-grade LPWAN technology with independent intellectual property rights in China, is independently developed by Longitudinal Technologies and has more than 10 invention patents at home and abroad. With unique low-power MeshAccess, active two-way communication, multiple protocol versions and other advantages, Longitudinal technology to provide users with excellent low-power Internet of Things communications solutions.
Network architecture
The ZETA network consists of access points (AP base stations, PoE or solar powered), Mesh trunks (optional, battery powered) and sensing terminals (battery powered). The base station connects the ZETA network with the Internet cloud.
Trunks can be deployed anywhere it needs it, with relays, signals can be easily reached at destinations, such as behind metal shields, inside underground passages, and so on. A large number of trunks interconnect with each other to form a Mesh Network, which effectively extends wireless coverage and improves network robustness and QoS.
ZETA appliances are easy-to-deploy and power-independent, enabling network coverage across the entire city in just a few weeks.
2 technical characteristics
Active two-way communication
The uplink (data feed) and downlink (control signaling) data transmission can be triggered at any time or according to any event according to user requirements.
Multi-hop self-network access
Flexible networking, blind coverage, node integration, network self-healing.
A variety of agreement mode
A variety of protocols to suit different applications, but also customized according to user needs.
Ultra-low power consumption
Much of ZETA device lifecycle is in ultra-low-power deep-sleep mode, extending battery life to 5-10 years.
Long transmission distance
The high receiver sensitivity of ZETA devices ensures a stable transmission of 2-10 km in urban environments and further in suburban or ideal deployment environments.
Large network capacity
Through innovative distributed network architectures, virtual OFDMA and ultra-narrowband transmission technologies, ZETA offers 3-10 times the network capacity of other LPWAN technologies.
safety
ZETA offers an efficient security solution for IoT applications: Supports hopping over 50 channels, access authentication, MAC address filtering, AES-128 (optional), LCG lightweight data encryption, and more.
Rate and spectrum
ZETA can operate in multiple sub-GHz frequency bands (such as: 433,470,500,787,868 and 915MHz, etc.), and supports 100bps-50kbps transfer rate. In addition, ZETA can also operate on a proprietary frequency band by changing configurations.
3. Ecological status quo
Through years of deep plowing and accumulation of the industry, the joint industrial chain partners, longitudinal technology has formed a smart city, smart lighting, smart community-based three vertical industry solutions, products and programs for many countries and regions around the world Providing services and establishing strategic cooperation with ZTE Microelectronics, China Tower, CLP Infrastructure Operation Company, Tunneling Corp., Fushun Optoelectronics, Kangshu Technology (Taiwan) and UKTI. Through the cooperation with Shanghai Tower, Shanghai has now built the largest LPWAN network in China, covering tens of thousands of metal covers with a transmission loss of 60dB at a cost of only 1 / 20th of NB-IOT, 1 / 5.
On the basis of MC-I spec, the square spec pulse dust filter with cloth bag MC-II is the amended and improved one. In addition to the advantages that I spec is high in the dust removing efficiency, big in the air capacity, stable in the performance, easy in operation and maintenance, MC-II has the better result than MC-I. Such as: it is not easy to build up the powder and its application is wide and so on. The device is widely used for the ventilation, dust removing and powder restoration in the grain, food, feed, metallurgical, chemical, building material, medical and other industries.
