Long-range Capability: High Link Budget
Maximizing the radio link budget between devices compensates signal attenuation indoors and outdoor, as well as for low antenna gain inherent to tiny footprint industrial designs and low-cost solutions. Then, maximizing link budget enables effective wireless links for hard-to-reach devices.
Highly sensitive receivers are specified to obtain acceptable operating range and last-mile coverage in the field, helping to avoid loading networks with dedicated repeater nodes. The Wavenis specification on receiver side is as follows:
• -110dBm sensitivity @ 19.2 kbit/s (50 kHz bandwidth channel)
• -113dBm sensitivity @ 4.8 kbit/s (25 kHz bandwidth channel)
Performance is achieved by combining data processing techniques such as fast Frequency-hopping spread spectrum (FHSS), Forward Error Correction (FEC) with BCH(21,31), data interleaving (16x16 bytes matrix) to increase reliability and also contribute to power savings by maximizing the success of communications on the first attempt.
• In compliance with FCC15.247 (North America) and ETS300.220 (Europe) wireless regulations, link budget features :
> 113dB with output power of 0dBm (1 mW)
> 124dB with output power of +14dBm (25 mW)
> 137dB with output power of +27dBm (500 mW)

Famous quotes containing the words high, link and/or budget:
“Esteem must be founded on preference: to hold everyone in high esteem is to esteem nothing.”
—Molière [Jean Baptiste Poquelin] (1622–1673)
“All successful men have agreed in one thing,—they were causationists. They believed that things went not by luck, but by law; that there was not a weak or a cracked link in the chain that joins the first and last of things.”
—Ralph Waldo Emerson (1803–1882)
“A budget takes the fun out of money.”
—Mason Cooley (b. 1927)
