I am looking for some guidance from the list. We will soon be deploying wireless payment devices (CDMA/GSM). We are looking at options on where to locate the servers that will run the backend payment gateways; we would like the least amount of latency between the servers and the wireless networks as possible. The wireless networks we will be deploying the devices on are: AT&T Wireless Verizon Wireless Sprint PCS Rogers Wireless Bell Mobility Telus Mobility Vodafone I was thinking we have a few options, to try and peer with the wireless networks directly, buy bandwidth from networks that are directly peered with the wireless operators or the Global Roaming Exchange Peering service that Equinix runs but I have not been able to find out much more then what is on Equinix’s public web site. We also have a need to peer with PayPal and Amazon. I welcome the lists comments and recommendations.
