Are there any reasons for not considering commercial (backbone) wireless gear for connecting points. It is a common practice for multi-building sites where project funds (or other constraints) prevent wired/fibre connections between buildings.

Subject: [RndTbl] aggregating dsl lines

Is it possible to aggregate DSL lines, to combine them to get X-times the
bandwidth on a single link? In this situation, I control both ends, the
DSLAM and the DSL modem side on the other end of some POTS runs (CAT3-ish
I assume, or worse).
Note, I don't want load balancing or fancy routing/sharing. I need double
(or more) the bandwidth for a single application (single TCP connection).
If required, we can have linux/bsd boxes we control at either end of the
links.
If it's not possible, does anyone have any other ideas for somehow getting
better bandwidth out of 500m POTS wires (quantity 4)?
Thanks!

At layers 2/3 you can do Multilink PPP or even something wierd and
questionably reliable like LACP over Ethernet-over-IP over the individual
connections, but given that it's only 500m and you control both ends the
best solution would likely be at

If you can put a box at both ends you can do compression between them with
an arbitrary size lookup table that is dynamic based on the traffic.
To get the single TCP connection going over both you'll need to go up the
stack - PPP or ipsec is what I would go with. You can't get away with a
simple carp system unfortunately.
Either way I don't see how you don't have ecmp or similar over the lower
link and run a tunnel with IP inside it.

This is an active area of research, particularly with the advent of multi-path TCP.
Presently, however, you have to hide the two-link-ness from the TCP layer, and essentially from the IP layer as well.
ECMP would work, as long as both lines are the same (this does not hold true as a dynamic assertion with DSL technology, *ever*).
LACP will *not* work.
If you have Linux boxes at both ends, you can use mod_bonding in its round-robin mode... I've done that in the past and it does work.
Far more effective, however, would be to upgrade to a symmetric VDSL2 setup that supports DSL bonded pairs.
That'll set you back around $600+ per end, IIRC, replaces both the DSLAM and the DSLR, but makes your problems go away by turning all the copper into a single Ethernet link.
I just worked with someone else on this kind of setup, I'll see if I can find the links...
