HN-1010/1510

Typical HopNet Applications

Introduction

The illustration below shows a complete network of multiple data sources connected
to a central base. Units that are out of range are connected through a repeater. See the
illustration of a point-to-point application on the next page.

Point to Multipoint

This common application consists of a central host and remote terminal units or other
data collection devices. The automatic repeat requests (ARQ) and acknowledgments
inside the radio are transparent to the computer system.
