I'm assisting a friend who runs a call center in the Philippines and needs a line of site connection to a secondary location at just under 100 yards. He's looking for a 100 link megabit with the capability to run VOIP reliably as well as run network data over a PCI compliant (secure/encrypted) wireless link. The connection MUST be as solid as a wired connection (or as close to as possible). This is out of my area of expertise, and I want to get some recommendations for what technology (Wimax/Microwave/etc), equipment and vendors would meet these requirements from those who specialize in this area.
Thanks in advance for the assist,
