Electrical Symbols — VHF UHF SHF
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. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. 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. 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.

Metropolitan area networks (MAN). Computer and Network Examples →
A list of parameters on which networks differ is very long. A large network with a range up to 50 kilometers is called metropolitan area network (MAN), and this type of network can include several local area networks. Metropolitan networks in their turn connect into global area networks. Here you will see a Metropolitan Area Network (MAN). This is an extensive network which occupies a large territory including a few buildings or even the whole city. The space of the MAN is bigger than LAN, but lower than WAN. MAN comprise a lot of communication equipment and delivers the Internet connection to the LANs in the city area. Computer and Networks solution for ConceptDraw DIAGRAM provides a set of libraries with ready-to-use vector objects to design various kinds of computer networks.

Cross-Functional Flowchart →
There are many tools to manage a process or to illustrate an algorithm or a workflow. Flowcharting is one of those tools. However, it may be difficult to show complex processes that require multiple attributes or several people in a simple flowchart, so a cross-functional flowchart would be a solution for that situation. To create such flowchart, group processes and steps to labeled rows or columns, and divide those groups with horizontal or vertical parallel lines. It is worth mentioning that there are different types of cross-functional flowcharts, like opportunity or deployment flowchart. This diagram shows a cross-functional flowchart that was made for a trading process. It contains 14 processes, distributed through 5 lines depicting the participants who interact with the process. Also there are connectors that show the data flow of information between processes. The cross-functional flowchart displays a detailed model of the trading process, as well as all participants in the process and how they interact with each other. The lines in the flowchart indicates the position, department and role of the trading process participants.
