HN-2010

Overview

Introduction

The HopNet 10 Series family of products provides reliable wireless connectivity for
either point-to-point or point-to-multipoint applications. The HopNet products are
built around the WIT2410 radio transceiver, which employs frequency hopping
spread spectrum technology. This technology ensures:

•

Maximum resistance to noise

•

Maximum resistance to multipath fading

•

Robustness in the presence of interfering signals

HopNet Products

The HopNet family of products is built with rugged enclosures compliant with IP 66
and NEMA 4X standards for outdoor and harsh industrial environments. All Hopnet
products work with each other and can be mixed and matched in a single network. All
HopNet Products are WIT2410 compatible and can be used with the WIT2410 OEM
based products as well as with the SNAP2410 10Base T access point. The HopNet
family consists of the following products:

External Antenna

HN-210X Base/Remote Unit

HN-510 Indoor Base/Remote Station

HN-1010 Outdoor Base/Remote Station

HN-1510 Indoor Base/Remote Station
