At one time, the technologies designers embedded in test, measurement and monitoring equipment sometimes seemed to lag the technologies engineers were developing and deploying. If this ever actually was the case, it certainly no longer applies, especially in the increasingly heady world of cellular networks. Engineers face novel, concurrent challenges in the deployment of second-and third-generation mobile wireless networks. Difficulties involving highspeed data links, network interoperability, complex signaling layers and the delivery of Internet content to mobile handsets all require attention. Deploying and managing those networks requires expertise in circuit-switched voice, packet data, Internet protocols and applications, new network elements and more. In these belt-tightened times, operators can ill afford to staff field offices with experts in all things, so designers need to come up with other enabling solutions for test and troubleshooting.
