Link Labs provides Internet of Things wireless connectivity and applicationdata management software for product and solutions companies.

Long Range Connectivity

www.Link-Labs.com

I. Adding connected intelligence to a product is a long and expensive

process for large OEMs and integrators.

II. Existing wireless technologies limit scale, add cost, and lower ROI.

III. Product companies underestimate the complexities and importance of

a robust data management application.

Symphony Link

Long Range, Low Power

Covers whole buildings to whole neighborhoods and is seamlessly

integrated to product data cloud with little integration.

- 10+ Years Battery Life- 10,000+ Connections per Gateway- Bi-Directional Data Communication

Everywhere, expensive, energy

Ubiquitous, but costly for service and hardware. Expensive and time consuming to develop new cellular products.

High density, short range

Works well for high, uniform density of connections, at short range.

Connectivity for Enterprise and Industrial Products

Replace High Density CellularSymphony Link has proven to be an effective replacement for cellular connections in fixed, medium-to-high density install

bases. Alarm panels and airport asset tracking are examples.

Battery Powered WhitespaceFor battery powered sensors and controllers, long range

wireless has not previously been possible. Symphony Link has successfully be integrated into wireless door locks,

parking sensors, and water meters.
