The problem with long range RF

Range increases with energy per information bit.

At given RF power budget, long-range implies low bitrate

For traditional modulation technologies, low bitrate means

narrow spectrum

A 30PPM quartz may deviate

as much as 25kHz on a

868MHz frequency…

FSK connectivity becomes

somewhat random below

20kbps !

Spread spectrum backgrounder (1)

Originally used for military communication, spread spectrum

transceivers transmit a known pattern of bits for each

information bit.

« 0 » « 01001011101001110101011101111011 »

« 1 » « 10011011011010101111101101110111 »

RF spectrum is « spread » accordingly

Spread spectrum backgrounder (2)

Receiver : incoming signal is multiplied by the known pattern

High complexity (synchronisation, doppler effects)

signal bits add up, noise bits tend to cancel each other

the information bit is recovered

Benefits of spread spectrum

Range : same performance as direct modulation of

carrier by information bit

Quartz alignment : spectrum is larger so the

quartz alignment issue is solved !

Same RF receiver may receive various bitrates

using different spreading factors (dynamic

adaptation to path loss)

Jamming resistance

Multipath transmission resistance
