Версія трансивера 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(МГц)	Range level	Comments
S10	806~826 МГц 1427.9~1467.9MHz 2401.5~2481,5 МГц	10км
S22	806~826 МГц 1427.9~1467.9MHz 2401.5~2481,5 МГц	30км	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	30км
S50	806~826 МГц 1427.9~1467.9MHz 2401.5~2481,5 МГц	55км
K50	1420~1529.9MHz	55км
S80	806~826 МГц 1427.9~1467.9MHz 2401.5~2481,5 МГц	80км
S150	806~826 МГц 1427.9~1467.9MHz 2401.5~2481,5 МГц	150км
K150	1420~1529.9MHz	150км

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(МГц)	Distance level	Suggestion
М3	806~826 МГц 1427.9~1467.9MHz 2401.5~2481,5 МГц	3км	Add outside power amplifier to increase the RF power and get more transmitting bitrates.
M10	806~826 МГц 1427.9~1467.9MHz 2401.5~2481,5 МГц	10км
M50	806~826 МГц 1427.9~1467.9MHz 2401.5~2481,5 МГц	50км

We also provide power amplifier to work with DLB module. 2W, 5W, 10W.

Only the same DLB model can communicate with each other, different DLB model can‘t communicate with each other. Наприклад, several DLB-S22 modems(or DLB-S22 + outside amplifier) can make up a star wireless network, and DLB-S22 can’t work with DLB-Kx/DLB-S50/DLB-S80/DLB-S150/DLBMesh3/DLBMesh10/DLBMesh50 in a same wireless network. For complex wireless application, it can consider to set up two or more wireless network in different frequency band to implement it, below topology is examples:

From our experience and our customer’s testing result, when the drone is flying on the height of more than 600m(to ground), 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(to ground), 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.
