Qualcomm QCA64x8 and QCA64x1 802.11ay WiFi Chipsets Deliver 10 Gbps Bandwidth

WiFi has evolved in recent years with the introduction of 802.11ad and 802.11ax (now called WiFi 6). THe latter is now official, and in the last year several 802.11ax chipsets and WiFi 6 routers have been announced, but I’ve not heard much about 802.11ad with claims of up to 7Gbps bandwidth at 60 GHz when unveiled in 2016. The latter have been supplanted by 802.11ay, with Qualcomm having just unveiled QCA64x8 and QCA64x1 802.11ay chipsets capable of delivering 10Gbps and operating at a frequency of 60 GHz. According to Wikipedia, 802.11ay is not really a new standard, but just an evolution of 802.11ad adding four times the bandwidth and up to 4 MIMO streams. Qualcomm chipsets will enable 10+ Gps speeds with wire-equivalent latency, while keeping the power consumption low, and bring the ability to play 4K UltraHD videos over WiFi, virtual / augmented reality games, fixed wireless mesh backhaul, […]

New WiFi Naming Scheme: 802.11n Becomes WiFi 4, 802.11ac WiFi 5, 802.11ax WiFi 6

Terminology used by engineers may be confusing for end-users, so for example in the TV market 720p becomes “HD Ready”, 1080p “Full HD”, and 4K may be referred to “Ultra HD”. A few years ago, I tried to buy a 1080p TV, and the seller was really confused at first saying they only had “HD Ready” or “Full HD” televisions. Two terms I had personally never heard of myself, but eventually we managed to understand each other… Up to now the official IEEE name for different WiFi standards like 802.11n, 802.11ac, or the new 802.11ax may have been a little confusing to consumers. So the WiFi alliance has decided to launch a new scheme naming scheme. We’ll soon have to refer to 802.11n routers as WiFi 4 routers, AC routers as WiFi 5 routers, and it will probably be less confusing for 802.11ax routers since I expect them to be […]

Air602 is another $2 WiFi IoT Module, Based on Winner Micro W600 Arm SoC

WiFi used to be fairly expensive to add to MCU projects with spending $30 to $40 just for a WiFi module pretty common just less than 5 years ago, but this all changed thanks to Tensilica based Espressif ESP8266 modules selling for $5 in 2014, and an active community gathering behind the WiSoC, and related modules and development board. ESP8266 modules are now available for under $2, and around two years ago it looked like we would have another option based on Arm Cortex-M3 with RTL8710 modules such as Pine64’s PADI IoT stamp also selling for about $2 in single quantities. However, most people did not really the benefit of switching to another platform based on Arm for this type of applications, and the products never really took off, many went away, and PADI IoT stamp appears to be one of the few survivors. Yet another $2 WiFi IoT module […]

Compulab WILD WiFi Router Supports WiFi RTT (802.11mc) Location

When Google released the first Android P preview back in March, one interesting new feature was indoor positioning through 802.11mc WiFi aka. WiFi RTT (Round Trip-Time). That looks promising so I started to look for 802.11mc capable routers, and all I could find were some Intel cards and Marvell chips with WiFi RTT, but not actual products. Since then Android 9 has been formally released, and today I’ve learned that Compulab launched a WiFi RTT capable router that will work with Android 9.0 phones. Meet Compulab WILD. Compulab WILD WiFi RTT router specifications: SoC (from a choice among three) Intel Atom x7-E3950 quad core processor @ 1.6 / 2.0 GHz with 18 EU HD graphics; 12W TDP Intel Atom x5-E3930 dual core processor @ 1.3 / 1.8 GHz with 12 EU HD graphics; 6.5W TDP Intel Celeron J3455 quad core processor @ 1.5 / 2.2 GHz with 12 EU HD […]

Embedded Linux Conference Europe & OpenIoT Summit Europe 2018 Schedule

Embedded Linux Conference OpenIOT Summit Europe 2018

The Embedded Linux Conference & OpenIoT Summit 2018 took place in March of this year in the US, but the European version of the events are now planned to take place on October 21-24 in Edinburg, UK, and the schedule has already been released. So let’s make a virtual schedule to find out more about some of interesting subjects that are covered at the conferences. The conference and summit really only officially start on Monday 22, but there are a few talks on Sunday afternoon too. Sunday, October 21 13:30 – 15:15 – Tutorial: Introduction to Quantum Computing Using Qiskit – Ali Javadi-Abhari, IBM Qiskit is a comprehensive open-source tool for quantum computation. From simple demonstrations of quantum mechanical effects to complicated algorithms for solving problems in AI and chemistry, Qiskit allows users to build and run programs on quantum computers of today. Qiskit is built with modularity and extensibility […]

$50 Fish32 Seed “Education” ESP32 Board Comes with Plenty of I/Os, Sensors, and Connectivity Options

Sometimes I feel the word “Education” is sometimes thrown around for marketing purpose, and AnalogLamb Fish32 Seed board for “ESP32 Community Education Board” feels that way to me as so far, I could not see any tutorials or other teaching/ learning resources for the board. Having said that I can see why it could be potentially used for education: the sheer number of features, sensors, and connectivity options should allow students to learn to program my different components around ESP32. It’s just at this stage it may not be such an easy platform to learn on. Fish32 Seed board specifications: Supported ESP32 Modules – ESP32-WROVER, ALB32-WROVER, ESP32-WROOM-32 Connectivity 802.11 b/g/n WiFi and Bluetooth 4.2 via ESP32 10/100M Ethernet (RJ45) via WIZnet W5500 chip with support for up to 8 independent sockets LoRa via SX1278 chip (433 MHz) Sensors NXP MPU-9250 with 3-axis MEMS gyroscope, 3-axis MEMS accelerometer, 3-axis MEMS magnetometer […]

NanoPC-T4 Review with Android 7.1 Firmware

NanoPC-T4 is one of the many Rockchip RK3399 SBCs now available, and as we’ve seen in the “unboxing review” the company sent me two samples. So far, I’ve been reviewing RK3399 boards with Linux distributions in posts such as “Checking Out Debian and Linux SDK for VideoStrong VS-RD-RK3399 Board” and more recently “AIO-3399J Development Board Review with Ubuntu 16.04“. But in this NanoPC-T4 review, I’ll switch to Android, specifically Android 7.1, as I’ll soon try Android 8.1 on Firefly-RK3399 which might make for an interesting comparison between the two versions of the OS, before switching to Linux with Pine64 RockPro64 board which I received yesterday. First Boot with NanoPC-T4 Development Board I had already assembled the board in the first part of the review, so I just added the two WiFi antennas, the optional USB to serial debug board, and connected various accessories and cables from left to right: USB […]

WiFiBoy32 is an ESP32 Portable Game Console and IoT Devkit

I’ve noticed that ever since Hardkernel launched their ODROID-GO “10th anniversary” portable game console based on ESP32 processor, most of the talk on IRC and social media is about this new toy, and people almost seem to have forgotten about the company’s Arm Linux boards 🙂 But recently, I’ve come across a somewhat similar ESP32 device called WiFiBoy32 that acts as both a portable game console and an IoT development kit. WiFIBoy32 specifications: Wireless module – ESP32-WROOM-32 wireless module with 802.11 b/g/n WiFi and Bluetooth 4.2 LE connectivity Display – 2.4″ 240×320 color SPI TFT LCD display Expansion – 2x 8-pin through holes with GPIOs, SPI, DAC, I2S,ADC, VP/VN, and power signals (3.3V, Vin, GND) Misc Top – 6x large gaming buttons, select and start push buttons, buzzer Bottom – PROG and RESET buttons, user LED USB – 1x micro USB port for power and programming (CP2102) Dimensions – 120 […]
