Weightless™
Carrier-grade Private Low Power Wide Area Network (LPWAN)
Weightless™ is a proven, high-performance LPWAN connectivity technology for the Internet of Things (IoT). It uses a narrowband modulation scheme, offering fully acknowledged bidirectional communications, to enable carrier-grade Quality of Service (QoS) and add-on functionalities.

Features




Reliable bidirectional communication
-
Supports both network-originated and device-originated traffic
-
FDMA+TDMA in 12.5 kHz narrowband channels offer optimal capacity for uplink-dominated traffic from a very large number of devices with moderate payload sizes
-
Operates over the whole range of license-exempt sub-GHz ISM/SRD bands for global deployment: 433/450/470/868/915/923 MHz
-
Adaptive data rate and Forward Error Correction from 625 bps to 100 kbps to optimize radio resource usage depending on device link quality
-
Transmit power control for both downlink and uplink to reduce interference and maximize network capacity
-
Acknowledgment and retransmission

System architecture
Weightless™ network uses a star topology and is composed of end-device communication modules and base stations. Crews of end-device communication modules connected to one base station for full bidirectional communication through Weightless™ protocol, which also manages device authorization and radio resource allocation. Ubiik offers base stations for both indoor and outdoor environments to meet customer needs. Base stations connect to the backend system through Ethernet or 4G backhaul for data processing and applications.

Why choose Weightless™?
Weightless™ offers the promised performance, network reliability and security characteristics of carrier-grade solutions.
