Enables High-Powered Edge Computing.

As a robust applications processor, CacheCrumb pushes intelligence to the extreme edge of the network to power real-time, distributed decision-making.

Removing Complexity with All-in-One Functionality

Rajant has simplified the way edge applications are developed, deployed, and managed with CacheCrumb, a platform bringing these powerful components together in one package:

A High-Powered Edge Web Server

As an HTML5 applications processor, CacheCrumb includes a built-in A9 SoC processor operating at 1GHz, 1GB of RAM, and 2GB of System Flash.

It also boasts one terabyte of SSD internal storage for rapid, high-volume capture and storage, and extensive I/O for extreme flexibility.

A Ruggedized BreadCrumb Node

CacheCrumb comes complete in a compact, extremely durable form factor and with all the dynamic mobile meshing capabilities of a Rajant BreadCrumb.

The portable, wireless mesh node can operate in extreme conditions and be easily affixed to stationary or in-motion assets, with an enclosure designed to IP67 standards.

A Secure, Open Standards Platform

CacheCrumb gives you full freedom of a flexible open source compute environment, and can be remotely administered without the need for a main controller or a control room.

Built for extreme security demands, CacheCrumb also supports several strong cryptographic options used for data and MAC-address encryption and per-hop, per-packet authentication.

Why Push Applications to the Edge?


Edge computing—also known as ‘fog computing’—pushes storage and processing for data-intensive, remotely distributed applications away from the central data center to the outer edges of the network—where the real-time action is happening, for real-time response.

This creates an ‘intelligent layer’ for localized processing closer to end-user clients and devices.

Cisco’s 2014 Consulting Services Global IoT Study revealed that 37% of respondents believe that in 3 years, most data generated by IoT solutions will be processed at the edge (mobile devices, applications, routers).

Enabling fog computing, CacheCrumb is ideal for applications that require:

  • Very low latency and real-time response
  • Time-sensitive data analysis
  • Streaming data and high-volume storage
  • Wide-spread geographical management and control
  • Wide area and real-time mobility access

Bringing these Next-Era Applications to Life


As a quantum leap in distributed application enablement, CacheCrumb is powering bold new progress across industries. Imagine the possibilities enabled for:

Municipalities – Powering ‘Smart Cities’

  • Distributed Video for Public Safety Surveillance
  • Traffic and Parking Optimization
  • Tourism Marketing and Infotainment
  • Energy Monitoring and Distribution

Transportation – Creating Complete Vehicle Interconnectivity

  • On-Board Vehicle Cameras and Communications
