A distributed antenna system is most often used to distribute cellular network coverage to heavily populated buildings, such as offices, high-rise apartments, shopping centers or sports stadiums. The Telecommunication facility is one of the major parts of the building utility to provide communications. The building owner shall provide space to house the telecommunication facility of the building. The distributed antenna system is part of the telecommunication facility of the building. The distributed antenna system, is an in-building solution comprising of a number of pico cells to provide wireless coverage and services using 2G. 3G, 4G, 5G, and even 6G wireless access technology. Definite number of antennas constitutes one single sector; this means that these set of antennas are strategically installed inside a building / compound to

As with other utilities, interruptions to service can have a serious impact. Poor quality of service due to lack of design foresight, use of inappropriate components, incorrect or improper installation, poor administration or inadequate support can threaten an organization's effectiveness. The cabling infrastructure within premises comprised both the application specific and multipurpose networks. The initial Philippine Electronics Code volume II edition discusses rules and standards for the Electronics and Communications Industry in planning for building telephone facilities geared towards the lowest possible costs, consistent with aesthetic  and safe practices, and which will result in minimum maintenance, future re-arrangement cos

    The effectiveness of using a single or multiple camera CCTV (Closed-Circuit Television) solutions depends on various factors and the specific security requirements. Single Camera Advantages The main advantage is cost-effective, they are more budget-friendly initially. Managing and maintaining a single camera is straightforward. Limitations A single camera can cover a specific are and detect obstacles or incidents, it only provides a restricted field of view. Blind spots may exist. If it is not positioned optimally, it may miss critical events. No backup if the camera fails or malfunction. Deploying a single camera is cost-effective and generally a good choice if the application is small. Multiple Camera Advantages Multiple cameras can cover larger areas, reducing blind spots. If one camera fails, other continue monitoring. Different camera type can be strategically placed. Multiple angles aid in identifying individual or incidents. View different areas simultaneously on a single mo

    Cisco Meraki MX Firewalls is a Unified Threat Management (UTM) and Software-Defined WAN solution. As a UTM product, Meraki MX provides content filtering, app-specific traffic control, intrusion prevention, malware protection, and site-to-site VPN that is deployable on hardware or virtually. It also enables firewall management remotely for 24x7 monitoring and accessibility. Users are able to deploy, monitor, and configure their Meraki devices via the Meraki dashboard web interface or via APIs. Once a user makes a configuration change, the change request is sent to the Meraki cloud and is then pushed to the relevant device(s).   Meraki Cloud Architecture The Meraki cloud is the backbone of the Meraki management solution. This "cloud" is a collection of highly reliable multi-tenant servers strategically distributed around the world at Meraki data centers and select public cloud service providers. For the remainder of this document we will refer to both the Meraki data cen

At least one TV box shall be planned for each room with the following construction and dimension. Wall plates shall have a 75 ohms barrel splice "F" female both ends 3/8" - 32 threads per inch mounted in the center. A washer and nut, matched specifically in the female splice adapter, shall secure the barrel splice to the wall plate. When attaching the cable to the splice adapter, special care shall be taken to avoid over tightening.  EXCERPTS | Cable Television System B

  Kidde EOL-15 End of Line Resistor 15K Ohm The function of an end of line (EOL) resistor is to monitor the integrity of the circuit in a fire alarm system. This is achieved by placing the resistor at the end of the wiring loop, completing the electrical circuit. The control panel of the fire alarm system continuously monitors the resistance of the circuit, which should match the resistance value of the EOL resistor. Any changes from readings may indicate a potential issue, prompting the system to signal a trouble condition. An EOL resistor should always be installed as the last device in the loop and never inside the control panel. Placing resistors anywhere other than the end of the line does not serve a purpose. Open Circuit Detection When there is a break in the wiring or a device is disconnected, it creates an open circuit. This means that the electrical current cannot complete its path through the circuit, resulting in an increase in resistance. The EOL resistor, placed
