Jellyfish Bridge is a unique AMR-to-AMI conversion solution that prolongs existing meters and rescues stranded AMR assets.

Drive-by/walk-by readings are replaced with regular remotely transmitted data configurable to 5-minute readings. Excellent VFM is delivered with up to 8 meters which were concentrated and decrypted using Patent technology in a single Bridge using a single SIM, vSIM or Token. Patchy AMI resulting from deep-pit transmission challenges are rescued by leveraging short range AMR thus maintaining the asset, delivering the data and causing zero disturbance to water supply or customer.

Providing unique and complete data-driven solutions to achieve Per Capita Consumption (PCC) reduction and Leakage elimination, we’re playing a crucial role to secure UK’s supply of water for the next fifty years.

Jellyfish Bridge by B4T

Solving deep pit connectivity

Convert your AMR (drive-by/walk-by) fleet into 15min/hourly/daily AMI. A super cost-effective, battery-powered Jellyfish solution concentrates up to 4x meters transmitting Open Meter Standard (OMS) EN13757. Installations on street furniture or in dry-risers in blocks of flats means you never need touch your existing installation. On-board decryption and remote key-handling enables efficient use of Low Power Wide Area Network (LPWAN) implementations such as Sigfox, MIoTY, LoRaWAN & NB-IoT.

Making sense of the data

Making sense of the data

Delivering insights otherwise hidden in data for rapid, automated responses and improved decision making with PROG.

PROG is built from the ground up with the specific purpose of scaling massive IOT. Its cloud based architecture is orchestrated by Kubernetes to scale horizontally for near zero integration of new sensors, data sources and customers, and vertically with automatic load balancing for unlimited performance.

deviceStatus is a software module that combines a sensors health and purpose in one view. This makes troubleshooting and operations consolidated for one user.

Advancing crop protection with high resolution sensors

Our solution opens new perspectives to farmers to address the challenges that are leading them to face decreasing incomes. According to the World Research Institute, the earth’s population will reach nearly 10 billion by 2050 - about 3 billion more mouths to feed than in 2010. To feed this increased population sustainably, the Institute has identified three gaps that must be closed.
