Wireless devices are evolving quickly into multimedia smartphones with fast data connections due to widespread deployment of high-speed standards, such as LTE. The Anritsu MD8430A Signaling Tester is a key LTE base station simulator for developing 3GPP LTE/LTE-Advanced compliant chipsets and wireless devices. In addition to verifying normal communications procedures, it supports fault operation tests, which are difficult to perform at connection with live base stations. It also supports LTE terminal R&D and verification tests under various conditions. Based on extensive experience in 3G markets, Anritsu has developed the MD8430A as a powerful LTE protocol/R&D test solution to help developers bring LTE wireless devices to market as soon as possible.
