Wireless networking with DLB

DLB module supports two operating modes: Access Node or Central Node. It can be managed through Web UI or AT command via uart3. DLB module supports features of a maximum of 16 Access Nodes connected to a Central Node. All of the Nodes are in the same wireless LAN and share the whole transmission bandwidth (maximum 30Mbps@20MHz throughput). For data from Central Node to Access Node, we call downlink, and for data from Access Node to Central Node, we call uplink. Uplink and downlink stream ratio can be controlled through web UI or AT command. When using the DLB module for Point-to-Point transmitting, uplink and downlink share the whole transmission bandwidth (maximum 30Mbps@20MHz throughput) too. DLB module supports networking modes: 點對點, 點對多點, 中繼, and Mesh (specify mesh version when ordering).

Add Tx Power Amplifier

The maximum RF transmission power of the DLB module is 25±2 dBm, which also provides a power amplifier to increase the RF Power to 2W/5W/10W. The below diagram shows how to add a power amplifier outside of the DLB module.

常問問題

Q1: What price of the DLB-M3 module?

A1: DLB-M3 is the DLB-Mesh-50km version. 50km requires a PA, so it is best to buy the complete TX900-Mesh -50km-5W or TX900-Mesh-50km-10W.

DLB is used with the first-generation Mesh, and DLC is used with the second-generation Mesh. The first-generation and second-generation modules of the MorningCore are not p2p compatible.

This is not a module. It is best to buy a complete machine. We will add the amplifier shell and antenna accessories. We adjust the parameters, and you can buy it and charge it to work. If you buy a module, it is difficult to install it without several years of technical experience.
