Detailed Answer
The LIDER LD series main frequency is 470MHz (UHF band); some models support 433MHz. 470MHz advantages: cleaner band (less interference), better diffraction/penetration (metallic environments), and longer range (200m nominal). Combined with FHSS spread spectrum, multiple devices on site do not interfere with each other. Frequency selection depends on the on-site interference environment; LIDER offers frequency band options.
| Main frequency | 470MHz |
| Alternative | 433MHz |
| Technology | FHSS |
Note:With many wireless devices around, 470MHz is more stable.
