10.8 MENU: LoRa Settings

From this menu user may change LoRa RF parameters.

  • Group Address and Device Address can be changed for the device itself
  • Tx Group Address and Tx Device Address is for the Tx Group. TLM can make link with only Tx Group Address and can send data to Tx Device Address in that Group
65535 which is 0xFFFF in Hexadecimal is broadcast address and can be used to send data to all devices in that group.
  • LoRa Signal Bandwidth and spreading factor can be changed

TLM uses Semtech’s LoRa proprietary spread spectrum modulation technique. This modulation, in contrast to conventional modulation techniques, permits an increase in link budget and increased immunity to in-band interference. It achieves sensitivities 8 dB better than FSK modulation.
LoRa also provides significant advantages in both blocking and selectivity, solving the traditional design compromise between range, interference immunity and energy consumption.
TLM offers three bandwidth options of 125 kHz, 250 kHz, and 500 kHz with spreading factors ranging from 7 to 12.
The spread spectrum LoRa modulation is performed by representing each bit of payload information by multiple chips of information. The rate at which the spread information is sent is referred to as the symbol rate (Rs), the ratio between the nominal symbol rate and chip rate is the spreading factor and represents the number of symbols sent per bit of information. The range of parameters which can be configured are given in the following tables.

Spreading Factor Chips/Symbol SNR/[dB]
7 128 -7,5
8 256 -10
9 512 -12,5
10 1024 -15
11 2048 -17,5
12 4096 -20

Note that the spreading factor must be known in advance on both transmit and receive sides of the radio link as different spreading factors are orthogonal to each other. Note also the resulting signal to noise ratio (SNR) required at the receiver input. It is the capability to receive signals with negative SNR that increases the sensitivity, so link budget and range, of the LoRa receiver.

  • LoRa error coding can be changed

To further improve the robustness of the radio link, TLM provides cyclic error coding with different coding rates. With using this coding scheme forward error detection and correction can be applied.

Coding Rate Chips/Symbol Overhead Ratio
1 4/5 1,25
2 4/6 1,5
3 4/7 1,75
4 4/8 2

TLM uses Semtech’s patented LoRa modulation technique which combines spread spectrum modulation and forward error correction techniques to increase the range and robustness of radio communication links compared with traditional FSK or OOK based modulation. Typically examples of TLM receive performances are given in the following table.

Signal Bandwidth/[kHz]  Spreading Factor  Sensitivity/[dBm] 
125 7 -123
125 12 -138
250 7 -121
250 12 -135
500 7 -116
500 12 -130

In this page user can enter decimal values and page will format it to hexadecimal automatically after cursor is moved out of scope
