Evolving wireless standards bring test issues

I can remember thinking how cool it was to read e-mail on my brand new Nokia 3650 smartphone nearly a decade ago. Although it took a solid minute to download e-mail over the old General Packet Radio Service networks, the freedom of getting information without being chained to a PC felt amazing.

Since then, we've gone from a world where GPRS data rates were slower than a 56k modem to one where most cell phone users enjoy true broadband data transmission rates over networks built on Evolution-Data Optimized HSPA/HSPA+ and, soon, Long Term Evolution technologies. We have all reaped the benefits of new wireless standards and kindly asked for more.

So it's no surprise that the future of standards for mobile communications and wireless connectivity is mostly about delivering higher data rates. With standards such as LTE Advanced and even IEEE 802.11ac right around the corner, the evolution promises to bring benefits to the end user but to introduce test challenges for design and test engineers.
