Qualcomm introduces first LTE chips to take advantage of unlicensed 5GHz spectrum

The new technology, called LTE-Unlicensed (LTE-U), works by taking advantage of unlicensed spectrum on the 5GHz band instead of licensed and controlled spectrum — typically in lower frequencies — traditionally used by phones. One of the main concerns some may have with this technology is how it will affect current Wi-Fi networks that run on the 5GHz band. Qualcomm says:
 In order for LTE-U to provide maximum benefit, it must operate harmoniously alongside billions of existing Wi-Fi devices. Qualcomm Technologies is working to integrate LTE and Wi-Fi at the system level, and employs a robust set of protection features to promote the best possible co-existence between LTE-U and Wi-Fi networks. These innovations are designed to ensure users can connect to the Internet however they prefer, while operators can make unified use of all available spectrum to increase capacity. This is designed to result in easier and cost-effective network deployment and operations for carriers and a seamless experience for their consumers.
The company also says that its LTE-U solutions, which include a new RF transciever and small cell SoC will allow users to take advantage of better performance than either LTE or Wi-Fi by themselves.The company plans to show the technology off at Mobile World Congress next week, where it will hold demonstrations using its user test equipment. As far as availability, the company says that it expects LTE-U integrated SoCs to be available in the second half of 2015 — the question then will be how long before phone makers and carriers want to integrate it into their own plans.

Google Already Rolling Out Android 5.0.2 to 2012 Nexus 7

It’s been less than two months since Android 5.0 made its public debut, and already Google is rolling out its second patch. An Android 5.0.2 factory image has just been made available for the 2012 Nexus 7, fixing a number of issues that have been plaguing users since Lollipop first arrived.
The new release comes with the “LRX22G” build number, and it replaces the Android 5.0.1 patch for the 2012 Nexus 7 (Wi-Fi). It includes both the changes made in that release, as well as some other welcome bug fixes.
“Most of these are adjustments in the kernel and startup scripts to boost CPU activity and maintain a bit higher performance,” Android Police reports. “There has also been another fairly significant update to fstrim, the process responsible for pruning the filesystem of unused blocks to prevent lag when attempting to write to a location in NAND storage containing outdated data.”
Google has also addressed an issue with AlarmManager, a process responsible for waking the device when apps and services need to perform different activities.
If you’ve been experiencing strange issues with your 2012 Nexus 7 since upgrading to Lollipop, then you’ll want to get your hands on this release as soon as possible. It’s only available as a factory image for now, so you’ll need to flash it manually, but we expect the over-the-air release to come soon.
We also expect Android 5.0.2 to be made available to other Nexus devices in the coming days and weeks.
