Qualcomm Gobi Modem: 3G/4G LTE Speed without Sapping Battery Life [VIDEO]

The cellular modem is the underlying component that allows any given mobile device to connect to the web and make phone calls. Qualcomm Technologies is a global leader in 3G/4G LTE technology, with its Qualcomm™ Gobi® products leading the way. With Gobi, we place equal priority on creating cellular modems that are superior in performance and as power efficient as our CPUs and GPUs.

To illustrate this potent combination of speed and power efficiency, we used lab-based test equipment to precisely monitor the throughput (Mbps) and power (Amps) of two devices featuring 4G LTE—one with a Qualcomm Gobi modem and one with a competitor's cellular modem recently launched in China—while connected. 

Both phones were fed the same voltage (3.7 volts) and the current consumption of each phone was measured. Meanwhile, we also captured data throughput to see the kind of download speeds the two devices can get under typical mobile conditions. By typical mobile conditions, we mimicked what it was like to drive on a highway at 30 km/hour with good cellular reception. Not only did the Qualcomm Gobi device deliver higher data rates (over 25%), but it did so with a lot less power. 

Lab-based test results alone may not paint the whole picture, especially when it comes to user experience, so we tethered both devices to a PC and used them as hotspots while streaming Ultra HD content under the same conditions. Without giving away the ending of the movie, let’s just say Gobi breezes through without a single interruption. But we’ll let you be the judge.

Learn more about Gobi modems at the Qualcomm booth at Mobile World Congress 2014. The booth will be located in Hall 3, Stand #3E10!
