802.11ax WiFi Aims to Deliver Higher Throughput (Up to 10 Gbps), Better Handle High Density Scenarios

802.11ax WiFi, also known as High-Efficiency Wireless (HEW), aims to improve the average throughput per user by a factor of at least 4 times in dense user environments, with a total bandwidth of 10 Gbps over 2.4 and 5.0 GHz . The new standard is still work in progress and is expected to be published in 2019. 802.11ax WiFi key features include: Backwards compatible with 802.11a/b/g/n/ac Increase 4x the average throughput per user in high-density scenarios, such as train stations, airports and stadiums. Data rates and channel widths similar to 802.11ac, with the exception of new Modulation and Coding Sets (MCS 10 and 11) with 1024-QAM. Specified for downlink and uplink multi-user operation by means of MU-MIMO and Orthogonal Frequency Division Multiple Access (OFDMA) technology. Larger OFDM FFT sizes (4x larger), narrower subcarrier spacing (4x closer), and longer symbol time (4x) for improved robustness and performance in multipath fading environments […]

Updating Star Cloud PCG02U to Ubuntu 16.04 with WiFi and HDMI Audio Support

I completed my review of PCG02U Ubuntu TV stick a few days ago, and I was quite satisfied with the device, but since Ubuntu 16.04 was released last month, I thought it might be fun to upgrade to the latest version of Ubuntu. I’m go through the complete steps including building a new kernel for HDMI audio, and the drivers for WiFi, but you should be able to install Ubuntu 16.04 for Bay Trail and Cherry Trail processor with the image made by Linuxium and a USB stick. Star Cloud PCG02U OS Support and Warranty Before I go through the instructions, you may want to read the conditions on MeLE’s Aliexpress PCG02U page. They meant Ubuntu 14.04 instead of 14.0.4, but the important part is that if something goes wrong trying alternative OS, you may lose your warranty. Upgrade Ubuntu 14.04 to Ubuntu 16.04 Upgrading from one LTS version to […]

Pebble 2 & Time 2 Smartwatches, and Pebble Core for Runners and Hackers Launched on Kickstarter

Pebble launched one of the first smartwatches in 2012, and is now one of the most famous name for wearables. The company has now launched another crowdfunding campaign for three wearables: Pebble 2 & Time 2 watches, and Pebble Core which can be either be used as a fitness tracker for runner, or by hardware hacker to play with IoT apps. Pebble 2 and Time 2 can receive notifications from your Android or iOS smartphone, include a built-in HRM for activity tracking, and a microphone for voice record and SMS, and are waterproof of up to 30 meters. To me the two key features of Pebble wearables are always-on displays, and long battery life, and the two new watches have a black & white (Pebble 2) or color (Time 2) always-on display, and up to one week of battery life for Pebble 2, and 10 days for Time 2.

Raspberry Pi 3 Repository Has Been Added to Android Open Source Project

Android has been ported to the Raspberry Pi boards in the past, but the images were not really usable because the implementation lacked 2D & 3D graphics support. The good news is that Raspberry Pi 3 is likely to officially support the latest version of Android soon, because rpi3 repository has been created in AOSP about 5 weeks ago. That’s all we know for now. Raspberry Pi 3 could then be part of the second wave of boards officially supported in Android “mainline”, as currently 96Boards Hikey is the only supported board in AOSP. However, If we go down in the git repo to android/device, we can also see MIPS Creator CI40, Aaeon Upboard, i.mx6ul picoimx board, Intel Edison and Minnowboard, and a few others. Some of the boards will run Brillo instead of Android however, or it could be a different project, so we’ll have to see what happens […]
