Table 6 An overview of the characteristics of uplink communication by SigFox, LoRaWAN, and DASH7 [24, 25, 35, 37, 40]
SigFox | LoRaWAN (according to EU regional parameters) | DASH7 | |
|---|---|---|---|
Modulation | Differential Binary Phase Shift Keying (DBPSK) | CSS / CSS / Gaussian Frequency Shift Keying (GFSK) | 2-GFSK |
Max. total message size (bytes) | 26 | 256 | 256 |
Max. payload size (bytes) | 12 | 59 to 250 | 251 |
Data rate (kbps) | 0.1 | 0.3 to 50 | 9.6 (lo-rate), 55.555 (normal), 166.667 (hi-rate) |
Max. transmission power (mW) | 25 | 100 (limited by the relevant regulatory limit, default 25 for end devices) | Limited by the relevant regulatory limit |
Bandwidth (kHz) | 0.1 | 125 | 25 (lo-rate), 200 (normal, hi-rate) |
Freq. range (MHz) | 868.034 to 868.226 (192 kHz) | 863 to 869.95 (with default center frequencies at 868.1, 868.3, and 868.5 for uplink communication and 869.525 for downlink communication) | 863 to 870 (lo-rate), 863 to 870 with the exception of 868.6 to 868.725, 868.925 to 868.975, 869.175 to 869.425, and 869.625 to 869.75 (normal, hi-rate) |
