Compression rates of up to 1:500 can be achieved.
#ALTERNATIVES TO VISIO FOR ELECTRICAL SOFTWARE#
The hardware or software that performs compression is called a codec (coder/ decoder). The core technology used in a videoconferencing system is digital compression of audio and video streams in real time. It has also been called 'visual collaboration' and is a type of groupware. "Videoconferencing is the conduct of a videoconference (also known as a video conference or videoteleconference) by a set of telecommunication technologies which allow two or more locations to communicate by simultaneous two-way video and audio transmissions.
The vector stencils library "Cisco telepresence" contains 8 symbols of videoconference and telepresence equipment for drawing Cisco computer network diagrams. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications.Ģ6 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. UHF radio waves propagate mainly by line of sight they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. Lower frequency signals fall into the VHF (very high frequency) or lower bands. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range.
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre.
