261 views

About products:
FDM-6600 is a wireless transmission product designed by IWAVE based on mature SOC chipset, which supports point to point and point to multi-point. 1 master node supports up to 16 sub-nodes to shares 30Mbps bandwidth for 1080P video transmitting. It is designed based on TD-LTE wireless communication standard, OFDM and MIMO technologies. It doesn't rely on any carrier's base station.
Supports Ethernet and full duplex TTL data transmission. And the control data transmission is higher priority than network signal.
It adopts the Automatic frequency hopping technology for anti-interference greatly reduce system power consumption and size of the module.

Long Distance Transmission: 10-15km (LOS air to ground)/1KM-3KM(NLOS ground to ground).
High-Speed Moving: All the nodes can be carried for fasting moving. And the wireless link is stable.
Following is the testing report:

Hardware Preparation

Device Qty
1.4Ghz FDM-6600 2
1.4Ghz Omni antenna(2.5dbi) 4
Router 1
Laptop 2
Power Source 2

Tools:

Flow Monitoring Software: The server uses BWMeterPro to monitor and count the client's filling rate in real time, and the client uses iperf for filling.
FDM-6600 Configuration: Connect FDM-6600 with laptop via RJ45 to do the parameters configuration (Frequency: 1.4Ghz/Bandwidth: 20Mhz).

Start Testing:
Place the FDM-6600(1) above ground 1.5meters with double 2.5dbi omni antenna.
Latitude: 34.85222.
