  1. Here are some information about the acknowledgement and ACK timeout with different distance and ieee802.11 series for reference. http://www.air-stream.org.au/technical/ack-timeouts-and-effects-distance-links
  2. MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol that provides resource-constrained network clients with a simple way to distribute telemetryinformation. The protocol, which uses a publish/subscribe communication pattern, is used for machine-to-machine (M2M) communication and plays an important role in the Internet of Things (IoT). From http://internetofthingsagenda.techtarget.com/definition/MQTT-MQ-Telemetry-Transport Is any EnGenius' wireless product supported it ?
  3. The Edison is the powerful new computing module from Intel®. The Edison packs a host of features, including WiFi (802.11a/b/g/n), Bluetooth (4.0 and 2.1 EDR), UARTs, I2C, SPI, USB, and 40 GPIO. It’s driven by a 32-bit Intel® Atom™ Processor clocked at 500MHz, supported by 1GB of LPDDR3 RAM and 4GB eMMC flash memory. To top it off, it’s housed in a tiny, 35.5 x 25.0 x 3.9 mm module. Edit from https://learn.sparkfun.com/tutorials/edison-getting-started-guide Here are some information Getting started with Access Point (AP) Mode for the Intel® Edison board https://software.intel.com/en-us/getting-started-with-ap-mode-for-intel-edison-board How configure an Intel Edison as a Wireless Access Point. http://reprage.com/post/how-to-configure-the-intel-edison-as-a-wireless-access-point Intel IoT Gateway Technology: Five Key Differences 1. Performance at the Edge That Enables Near Real-Time Analytics, Local Decision-Making, and Tighter Process Controls. 2. Advanced Security for Trusted Data from Edge to Cloud and Protection from Costly Attacks 3. Scalability for Varying Levels of Gateway Performance Requirements 4. Manageability for Secure Remote Upgrades and Services 5. Faster, More Flexible Deployment with a Platform That Supports Your Choice of Operating Systems and Ecosystem Applications Intel® IoT Gateway Technology http://www.intel.com/content/www/us/en/embedded/solutions/iot-gateway/iot-gateways-product-brief.html https://software.intel.com/en-us/iot/hardware/gateways
  4. The Linux Wireless Extension and the Wireless Tools are an Open Source project sponsored by Hewlett Packard (through my contribution) since 1996. The Wireless Extension (WE) is a generic API allowing a driver to expose to the user space configuration and statistics specific to common Wireless LANs. The Wireless Tools (WT) is a set of tools allowing to manipulate the Wireless Extensions. Here are tools iwconfig manipulate the basic wireless parameters iwlist allow to initiate scanning and list frequencies, bit-rates, encryption keys... iwspy allow to get per node link quality iwpriv allow to manipulate the Wireless Extensions specific to a driver (private) ifrename allow to name interfaces based on various static criteria The latest stable version of Wireless Tools is version 29. The main features of the latest beta is support for non-ASCII ESSIDs (such as localised ESSID), support for displaying Scanning Capabilities, slightly bigger scan buffer, fixing minor bug iwconfig parser and minor enhancement to ifrename : Wireless Tools version 30-pre9 (beta) Edit from http://www.labs.hpe.com/personal/Jean_Tourrilhes/Linux/Tools.html Here are Debian bugs in package wireless-tools (version 30~pre9-11) in unstable. https://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=wireless-tools;dist=unstable
  5. I like to move it,move it~

  6. 由 OpenStack社群、iThome及臺灣雲端運算產業協會聯手舉辦全臺最大規模的OpenStack技術大會(OpenStack Day Taiwan 2015),2015年8月11日於臺北登場時,不僅吸引超過1,700人報名到場參與,參加人員更從企業CEO一直到開發人員都有。OpenStack基金會創辦人,也是現任首席營運長Mark Collier更首度親自來臺參與這場年度盛會。 2016 透過這些案例的分享,將有助於加快臺灣在地化OpenStack生態系的成形。目前在臺灣也已經看到有初步的雛型,未來更要讓這些有意採用OpenStack的企業,能直接就近在臺灣取得資源,替企業在服務提供和應用開發上帶來更多的優勢。 From http://openstack.ithome.com.tw/
