Hopnet Data Integrity; Flexible Power Management; Advanced Features - Murata Hn-210 Manual

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

The power can be set at 10 milliwatts or 100 milliwatts using the included software.
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.

Advanced Features

HopNet modems have many advanced features:
• Employ frequency hopping technology with up to 75 channels in the 2401 to
2475 MHz frequency range
• Support digital addressing for up to 64 networks, with 62 remotes per
network.
• Use transparent ARQ protocol
• Use same hardware for all supported data rates
• Supports up to 115 Kbps asynchronous data rates
• Full Duplex operation
• Store setup configuration in nonvolatile memory (FLASH)
• Fast acquisition – less than 2 seconds is the typical time to acquire hopping
pattern
• Smart power management features
