Cutting RF power in W-CDMA phones News & Analysis 6/30/2004 Post a comment The spread-spectrum wireless communications standard, IS-95/3GPP, embodies stringent specifications for linearity and adjacent-channel power ratio (ACPR), says this Maxim engineer. The power amplifier does not operate continuously in voice mode. When the phone user isn't speaking, it runs at a half rate (50 percent of the time) or at a one-eighth rate, so there's no worry about the phone's heating during voice mode. But in data mode the PA runs continuously until the data transmission is complet
Power reduction remains top priority for 3G mobiles News & Analysis 6/30/2004 Post a comment Earlier this year, Vodafone chief executive officer Arun Sarin said that product quality deficiencies would slow the rollout of third-generation (3G) mobile phones. They are bulky, they get hot, and they don't have enough battery life," he said. Rob Keenan uses this as the kick-off point from an EE Times' article package on cell phone power managmenet. The big issue is in W-CDWA power consumption, he warns.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
