Customer Comments "We can do more with less. Our engineers can spend more time analyzing the data and less time driving around.“ "We can manage many more cell sites with the same number of engineers." "We can identify and solve problems in the network before they affect our subscribers." "As we add complex 3G features and capabilities this system will allow us to properly manage network performance." "Switch data is helpful but this tells me where my drop calls happened and it provides the data from the phone perspective to help troubleshoot it." "One sixth of our wireless PC data users had 80% blocking and we didn't know it until the RMS system started monitoring our network." "We needed a system that would provide continuous drive test data to feed our frequency planning software. Now we have found it." "A product that measures voice and data on multiple networks, doesn't cost much and doesn't require an expensive engineer to drive around. That's incredible!".
Summary • Automatic drive testing • Improves Quality • Decreases cycle time to fix problems • Identifies problems sooner • Reduces capital requirements • Reduces manpower requirements • Quality improvement at lower relative cost • Upgradeable for future enhancements
