Trials Underway for Wireless Mesh Communications Device

Trials are underway for a new communications device just released for use with scalable, kinetic wireless mesh technology.

Rajant Corporation – which Rigzone reported on earlier this year – this week launched the CacheCrumb node, a wireless transceiver with built-in processing power that allows applications to be pushed to a edge of a network for quicker access, the company said in a July 22 press statement.

The new CacheCrumb is similar to Rajant’s ME4 line, but has an applications processor tuned for distributed video, sensors, algorithms and up to a terabyte of storage. CacheCrumb’s extra processing power and solid state memory means it can perform edge-processing, allowing video and other data to be stored, ‘groomed’ and consumed directly from the device.

Rather than adding multiple separate boxes and creating a much bigger footprint, CacheCrumb provides capabilities for that can support different applications through an integrated device, said Paul Hellhake, Rajant’s chief technology officer, in an interview with Rigzone.

CacheCrumb meets the demand for video that is growing not only in oil and gas, but other industries as well as companies want security and the ability to monitor equipment if case of failure. The device can store up to 30 days of video, meaning video can be accessed without having to send it across network resources until it’s needed. Video can be streamed immediately, meaning they don’t have to be collected and reviewed later, Hellhake noted.

Sensor data also can be stored on CacheCrumb, meaning bandwidth isn’t chewed up by data being sent to a central database. Rajant is working with one oil and gas client to help them address their needs, which include the ability to gather, storage and analyze data locally, Hellhake said.

Third party devices can be hooked with other breadcrumbs to provide the benefits of CacheCrumb, but would require additional power sources, such as a laptop hooked up on location to add processing capability. But hard drives tend to fail in outdoor environments, Hellhake noted.

Hellhake said the company is still looking at applications for monitoring with sensors, and expects to come out with new applications shortly.
