DLB DLM Transceiver Version

There are two series version of DLB(DLM) transceiver, one is star wireless network version, ang isa ay Mesh wireless network na bersyon.

Bituin ang bersyon ng wireless network

Numero ng bahagi	Frequency band(MHz)	Range level	Comments
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

Maaaring gamitin ang star wireless network na bersyon para sa point to point na pagpapadala, tumuro sa maramihang puntong pagpapadala at isang node relay na nagpapadala.

Mesh na bersyon ng wireless network

numero ng bahagi	Frequency band(MHz)	Antas ng distansya	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

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. Halimbawa na lang, several DLB-S22 modems(or DLB-S22 + amplifier sa labas) maaaring bumuo ng isang bituin na 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.
