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:

About HopNet Products
Introduction
This section provides operational information about the HopNet products.
Operating Frequency
The HopNet family operates in the 2.4 GHz ISM band that allows for license-free use
and worldwide compliance.
HopNet Frequency Hopping Spread Spectrum Advantages
In the frequency domain, a multipath fade can be described as a frequency selective
notch that shifts in location and depth over time. Multipath fades typically occupy
five percent of the band. A conventional radio system typically has a five percent
chance of signal impairment at any given time due to multipath fading.
Frequency Hopping Spread Spectrum reduces the vulnerability of a radio system to
interference from jammers and multipath fading by distributing or spreading the
signal over a larger region of the frequency band.
The fade resistant, HopNet frequency-hopping technology employs up to 75 channels
and switches channels over 100 times a second to achieve high reliability throughput.
HopNet Data Integrity
An on-board 3 KB buffer and error correcting over-the-air protocol ensure data
integrity even in the presence of weak signals or jammers. The serial interface
handles both data and control of asynchronous data rates of up to 230 Kbps.
Flexible Power Management
You can set the transmit power at 10 milliwatts or 100 milliwatts. Reduced power can
reduce the size of the coverage zone, which may be desirable for multiple network
indoor applications. You can also place the transceiver module in a power-save mode,
which enables smart power management. Smart power management allows a remote
unit to drop into a lower current standby mode during transmission or receiving gaps.
This feature also allows Hopnet products to be used in various countries where the
output power requirements may vary due to regulation.
