  • Everything is Duplexing

    Fiber optic wires spread apart and sending out light.

    When you talk to someone on the phone typically someone makes a statement or asks a question then the other party responds. We take turns. You talk then I talk, then you talk then I talk – back and forth. That is also how many internet services and wireless communications work as well — they […]

  • Google’s Cell Service Play

    Google Project fi logo - a green and blue lower-case "f" and yellow "i". The dot above the "i" is white and overlaps the cross of the "f".

    Google likes to jump into a number of businesses that involve technology. They are heavily involved in robotics and are developing a self-driving car, conduct a number of research projects, jumped into the cloud computing ring, more recently became an ISP (Internet Service Provider) by rolling out fiber-optic internet to a number of cities across the United States, […]

  • WiFi Traffic Management Algorithm

    Visual representation of the 2.4 GHz WiFi frequency channels. Each channel is represented by a dotted half-circle representing 22 MHz of bandwidth. The half-circles representing the 3 front channels (1, 6, and 11) have solid outlines. The others overlap behind and between the front 3 channels except for channel 14 which only overlaps the edges of the 12th and 13th channels.

    Phys.org reports on a new algorithm developed by a doctoral student at École polytechnique fédérale de Lausanne (EPFL) that changes frequencies and bandwidth usage based on the type of data packets being sent and received. Many routers today are set by default to use channel 6 of the 2.4 GHz frequency which causes a build-up […]
