3 Secrets For Extending The Range Of Blue, and Zigbee




Internet of Thing (IoT) is taking over the world quite fast. This interconnection of physical devices relies on 2.45GHz short range radio transmission systems. These systems include both the Bluetooth and the Zigbee technologies. While these technologies have good wall penetration, their range often causes numerous challenges. Designers now integrate several manufacture parts together to come up with solutions to boost the range of the 2.45GHz wireless systems.

Boosting 2.45 GHz radio systems

Mesh networking

Mesh networking involves the bouncing of signals between dozens or even hundreds of nodes so as to spread a network connection over a large area. Nodes are small radios that perform similarly to wireless routers. These nodes utilize Wi-Fi standards (802.11 a/b/g/n/ac range) to communicate both with each other and with users. They are programmed with a software that guides how they interact with each other within the network. This software also enables the nodes to automatically choose the shortest and safest path between two points. The more the nodes, the bigger the transmission range.

Advantages of mesh networks

  • It uses fewer wires, making it cheaper to set up
  • The range and speed of the network increases with the increase in the number of nodes
  • Mesh networks are both self-healing and self-configuring
  • Mesh nodes are easy to install and uninstall

  • Disadvantages

    • Mesh networks are capital intensive
    • They are complex, hence hard to manage

    Manufacturer part required to implement a Mesh Network

    At the heart of the mesh networks are radios that receive and send the radio signals. There are numerous manufacturers who manufacture such radios. They include,
    • Cisco
    • Motorola
    • Linksys
    • ABB
    You can download the data sheets of the various and compare various radios suits your application best.

    Forward Error correction

    Forward Error Correction (FEC) is the process in which digital data transmitters add extra information called check bits to the data stream. The radio receiver analyzes the check bit information to trace and correct errors. When the errors have been corrected, the check information is then isolated from the data stream leaving behind the original information (voice, video, or data) intact. All these are done in real time while the data continue to be received. The methods used to detect and correct errors vary with the kind of information being transmitted through the network. Besides reducing the number of errors in transmission, FEC extends the operating range.

    Advantages of FEC

    • Back-channels not required
    • Leads to reduced bandwidth requirements

      • Disadvantages

      • Sometimes the check bits become the source of errors

      Manufacturer parts required for FEC

      Listed below are some components and transceivers that when inserted within the transmission channel support FEC;
      • AX5042
      • QSFP28
      • FTLC9554REPM

        • Manufactures parts required for SNR boosting

        Below are some components used in SNR boosting;
        Successful extension of the range of the 2.45GHz wireless system is very crucial will go a long way in boosting IoT efforts in homes and institutions. Manufacturer parts listed above are just a tip of the iceberg. They are meant to guide you in the right direction. Consult your system designer for more options as far as the components are concerned.

Mid-Power LEDs: Less Expensive for LED Lights

Image
  Mid-power LEDs Do you see that sleek, ultra-thin HD TV set in front of you? Well, its existence has been made possible by mid-power LEDs. Which can be  powered the shift from old cold CRT backlight TV. These are tiny LEDs measuring a few millimeters square. Courtesy of their size and weight, hundreds of them can be fitted unto a single light source but still weigh less than 250 grams. They can be pa packaged densely compared to high-power white LEDs. They offer relatively high-power white LEDs and a more uniform appearance. They also consume less power. Mid-power is for many reasons touted as the best alternative for LED lighting. High-power, mid-power, and low power LEDs To get a better grasp on mid-power LEDs is important to understand the three classifications of LEDs Low power They were the earliest LEDs in the market and were mostly used for indicator lights and identifying the status of machine condition. High power They are costly thus were initially used for research. Comme

An Introduction to Brushless Direct Current (BLDC) Motors

Image
The growing popularity Has your phone vibrated today? Well then, you just experienced a  brushless DC (BLDC) motor  in action.  BLDC motors  are synchronous motors that are powered by direct current through a drive module or controller. BLDC motors have witnessed rapid growth in popularity owing to their construction that makes them superior to the brushed counterparts. BLDC motor construction Rotor The rotor is made up of permanent magnets and its number of poles (North and South poles) varies from two to eight pairs. The permanent magnets are made from ferrite magnets. However, permanent magnets made from rare earth alloys are increasingly becoming popular owing to the advancement in technology. Rare earth alloys offer more magnetic density per volume while enabling the rotor to compress further for the same amount of torque. Such alloys also improve the size to weight ratio. There are two rotor designs for BLDC motors; the inner rotor and the outer rotor design. I

Little Know more about Brush-less Motors

Image
Brushless motors Brushless differs from conventional dc motors in the sense that it does not have brushes. Commutation is done using electronic drives to feed power to the stator windings. They consist of a rotor which is in the form of a permanent magnet and a stator that is in the form of polyphase armature windings. A  brushless DC motor  can be constructed in two ways; one is by placing the rotor outside the core and the other is by placing the rotor inside the core. How a brushless motor works Brushless motors are driven by electronic drives that  switch  the supply voltage between the stator windings while the rotor turns. There is a transducer that monitors the position of the rotor as it turns and conveys the information to an electronic controller. The controller then decides which stator winding to be energized based on the position of the rotor. Electronic drives are made up of two transistors each phase which is run by a microprocessor. The magnetic field i
