Versi Pemancar DLB DLM

There are two series version of DLB(DLM) transceiver, one is star wireless network version, the other one is Mesh wireless network version.

Star wireless network version

Part number	Frequency band(MHz)	Range level	Komentar
S10	806~826MHz 1427.9~1467.9MHz 2401.5~2481.5MHz	10km
S22	806~826MHz 1427.9~1467.9MHz 2401.5~2481.5MHz	30km	The maximum transmitting range of different part numbers are different. DLB module can measure the wireless transmitting range in real time. The “Range level” means the maximum distance. Add outside power amplifier to increase the RF power for different range.
K22	1420~1529.9MHz	30km
S50	806~826MHz 1427.9~1467.9MHz 2401.5~2481.5MHz	55km
K50	1420~1529.9MHz	55km
S80	806~826MHz 1427.9~1467.9MHz 2401.5~2481.5MHz	80km
S150	806~826MHz 1427.9~1467.9MHz 2401.5~2481.5MHz	150km
K150	1420~1529.9MHz	150km

Star wireless network version can be used for point to point transmitting, point to multiple point transmitting and one node relay transmitting.

Mesh wireless network version

part number	Frequency band(MHz)	Distance level	Suggestion
M3	806~826MHz 1427.9~1467.9MHz 2401.5~2481.5MHz	3km	Add outside power amplifier to increase the RF power and get more transmitting bitrates.
M10	806~826MHz 1427.9~1467.9MHz 2401.5~2481.5MHz	10km
M50	806~826MHz 1427.9~1467.9MHz 2401.5~2481.5MHz	50km

Kami juga menyediakan power amplifier untuk bekerja dengan modul DLB. 2W, 5W, 10W.

Hanya model DLB yang sama yang dapat berkomunikasi satu sama lain, model DLB yang berbeda tidak dapat berkomunikasi satu sama lain. Sebagai contoh, beberapa modem DLB-S22(atau DLB-S22 + penguat luar) dapat membuat jaringan nirkabel bintang, dan DLB-S22 tidak dapat bekerja dengan DLB-Kx/DLB-S50/DLB-S80/DLB-S150/DLBMesh3/DLBMesh10/DLBMesh50 di jaringan nirkabel yang sama. Untuk aplikasi nirkabel yang kompleks, ia dapat mempertimbangkan untuk menyiapkan dua atau lebih jaringan nirkabel dalam pita frekuensi berbeda untuk mengimplementasikannya, topologi di bawah ini adalah contohnya:

Dari pengalaman kami dan hasil pengujian pelanggan kami, ketika drone terbang di ketinggian lebih dari 600m(ke tanah), the distance between two DLB based 5W device in 1.4GHz band can be reach 80km directly(one on the drone, one on the ground). Two Omni-directional 2dB antennas on the drone, and two Omni-directional 7dB antennas on the ground. when the drone is flying on the height of more than 1000m(ke tanah), the distance between two DLB based 10W device in 1.4GHz band can be reach 150km directly(one on the drone, one on the ground). Also Two Omni-directional 2dB antennas on the drone, and two Omni-directional 7dB antennas on the ground.
