For a local area network (LAN) to provide good coverage, improved antennas are often a better (and less expensive) option than more access points. Directional antennas are sometimes the better choice, but often omnidirectional gain antennas will work well.

Part 1 in the “How to Make an EFM8-Based Sound Synthesizer” series, which will design a sound synthesizer that can play standard musical notes. We will accomplish this using a low-cost, small-form-factor EFM8 microcontroller in conjunction with a few external components and a speaker.

Multiplexing was developed in the early 1870s, but it’s become much more applicable to digital telecommunications in the late 20th century. Today, frequency division multiplexing (FDM), time division multiplexing (TDM), and wavelength division multiplexing (WDM) have become an extremely important asset to telecommunication processes and has greatly improved the way that we transmit and receive independent signals over AM and FM radio, telephone lines, and optical fibers.
