[c-nsp] HWIC-3G-* experience?

[Ryan Hughes]

Site survey, site survey, site survey. I've had limited exposure with the
3G's and haven't enjoyed it. Make sure whichever carrier you're
evaluating/planning with perform site surveys for each and every location;
this will help put some of the burden on them to prove that your specific
facility is even capable of riding on the link. Some will often offer cables
for extending the dipole antenna for better placement for signal. Quite
honestly, pick a carrier you have the best relationship with and make them
come to the table for support of these. Without their intervention/support,
you'll be left pulling your hair out.
Make sure your design for the backup connection involves some type of
dynamic crypto map as you'll often change ip addresses on these networks
which can lead to interesting anti-replay issues. One of my customers is
having reasonable success with this for fast office deployments but the nuts
of it boils down to proper site assessments before installation and the
logistics around it.

Good Luck.
