I am trying to send the PointCloud2 topic through a wireless network. Is there already some implementation in ros I am missing? Any good link you would recommend?

Just start your publisher on one machine and the subscriber on another, as described in this tutorial. This is not specific to wireless networks.

In case you have to limit the bandwidth, have a look at the topic_tools stack, especially the throttle node.

Make sure that all channels in your point cloud are useful for the posterior processing/visualization. Remove them in other case. Decreasing the dimensionality of your data should be always one the first choices when performance problems appear.

If you don't need high pointcloud density you could downsample it first before publishing. (Voxelgrid).
