As mobile communications technology converges, designers need to be increasingly adept at adaptation. By Mike Richardson.

Today’s communications designers and test engineers face the challenge of making informed technology choices from an array of new and innovative products, and the myriad of test and measurement techniques these technologies require. These decisions are further complicated by the convergence of multiple technologies into mobile handsets. Designers must also contend with evolution in existing technologies as well as the emergence of new ones – both of which make the task more complicated than ever before. To address these challenges, innovation in both design and test is required to quickly move existing and emerging wireless technologies forward, and in the past year alone, communications test and measurement solution providers have taken different approaches.
