VM31 Mesh Video Link

VM31 is a Mesh radio that integrates essential functions including video, data, and remote control signal transmission. It supports a maximum of 32 nodes for networking, featuring up to 31 hop routing capabilities, allowing direct communication between any two nodes within the network.

Built on the LTE wireless communication standard, VM31 incorporates critical technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and Multi-Input and Multi-Output (MIMO), enabling support for various bandwidth allocations. It operates across two frequency bands: 1.4G and 800M and achieves a maximum transmission power of 25dBm, covering a transmission distance of up to 50km.
