By bonding, you might be referring to aggregating network connections (also called cellular multiplexing), which was reviewed in this
page, but the other options seem to be more expensive than Teradek.
to this post, which is as recent as I could find. Combining multiple streams into a single stream with Wowza is:
a workflow that we are aware of and are looking into how we can support it in future versions of Wowza Server.

You might however look into
VLC mosaic for a workaround.
Alternatively, you could post a request to the
find a consultant forum and see if any of the developers there have a module or workflow you could purchase. Or, if anyone could develop a module, or help you get this working.
Teradek is probably the best option for you if you are concerned about cost. They are also part of the
Works With Wowza partner program. Please note that you would still need additional hardware/software in order to manage the network aggregation and routing. In this
thread, they discuss using Sputnik for this function.
