I had evaluated a solution in which this might be palatable a while back. There are some basically "layer 1" type P2P wireless links that would allow L2 signalling to flow across them. They basically take Ethernet and output RF. In this instance, you could use Etherchannel load balancing. This would theoretically allow you to bundle different P2P radios using seperate frequencies to achieve a multiple of a single radios bandwidth.
Both OSPF ECMP w CEF and etherchannel use a hashed form of load balancing, so it wont be packet by packet, so reordering will not occur. If you can, I would recommend etherchannel, and if the LACP/PAGP frames cannot traverse the link, use L3 OSPF ECMP.

Subject: OSPF loadbalancing or Etherchannel
All,
I need to bundle two high-speed redundant wireless connections:
1) Would ik use a Layer3 link across each wireless connection and use OSPF Equal cost to load-balance the traffic ?
2) Would i use Layer2 Etherchannel bundling of the two links to load-balance traffic ?
I do have voice traffic that does not allow reordering of packets across these links.
regards,
Geert
