Transcription of Long-range RF communication - why narrowband …
{{id}} {{{paragraph}}}
Executive summaryA key parameter for a wireless communica-tion system is the communication range. Fundamentally, the range is dictated by the communication data rate. There are several technical options to increase range by reduc-ing data rate. Two solutions are compared here; scaling the receiver bandwidth to the signal to reduce noise seen by the receiver ( narrowband system), and adding coding gain on a higher rate signal to combat the high receiver noise in a wideband is shown that adding coding gain for long range communication will negatively affect sys-tem performance by.
Long-range RF communication: Why narrowband is the de facto standard March 2014 2 Texas Instruments increases the probability of interference/collisions with other wireless systems.
