Ready to deploy WISP

5 Ready to deployWISP is suited for Proof Of Concept, Pilots and low to medium volume applications. The WISP seemlessly connects to the WizziLab’s DASH7 Industrial IoT platform.

DASH7 Access Point (gateway) and Network Management Platform(https://dash7board.wizzilab.com)

For details visit our website : www.wizzilab.com/products

Its modular approach allows to validate the customer application and use cases with minimal investment.

The embedded firmware framework developed by WizziLab and the off the shelve companion board allows our team to create your specific applications very quickly and deploy to the first prototypes in weeks.

Should the volume grow, a custom design, cost optimized and with a custom form factor is recommended
