Cable television, originally known as Community Antenna Television or CATV, was introduced in the 1940s in areas that could not receive the TV signal without obstruction. The solution was to place an antenna on top of a large utility pole and locally share the signal. CATV, as we now know it, was created when the signal from one master antenna was distributed over a large area using coaxial cable and amplifiers. The key innovations in cable TV are optical feeder links, digital compression techniques, and service integration.

The technical operating parameters needs to be followed of a RF signal over the outside plant to ensure the quality of signal at the subscriber terminal. IP based Television (IPTV) standard and Over-The-Top (OTT) service.

Analog Cable TV
This applies to the performance of a cable television system as measured at the output of the head-end and subscriber terminal with a matching impedance of 75 Ohms at the termination point of the cable television system. The requirements are applicable to each NTSC video downstream calbe television channel in the system.

Digital Cable TV
This applies to the performance of the cable television system offering digital TV services utilizing DVB-C standards. Digital channels relative to analog channels shall be aligned based on a certain parameters.

Cable Internet
This applies to the performance of Data Over Cable Service Interface Specifications (DOCSIS) cable internet only. The RF plant shall meet the specific requirements on Philippine Electronics Code book III.

Why do the Philippines have slow internet?

Image
  It isn't that the country's regulatory landscape makes it difficult for internet service providers to put up the necessary infrastructure.  Actually the approval of electronics systems designs and plans in the city and municipal areas isn't difficult, it was most likely because they could not enforce the law. And also corrupt government officials exploit this lack of enforcement to steal money from the telecommunication companies. The Department of Interior and Local Government (DILG), Department of Public Works and Highways (DPWH), Department of Information and Communications Technology (DICT), has released memorandum circulars on RA 9292, Electronics Engineering Law of 2004 regarding its implementation. The Local Government Units should already have a guide in formulating a unified and defined set of procedures in the releasing electronics permit and in the checking and approving of electronics system plans and designs. The country's regulatory landscape NEVER make...

The Distributed Antenna System

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 / compoun...

Examples of renewable energy sources include wind power, solar power, bio-energy (organic matter burned as a fuel) and hydroelectric, including tidal energy.  Renewable energy engineers develop and design systems to use energy from renewable resources, such as the sun, wind, and water. Renewable resources are energy sources that are naturally and continually replaced. They are alternatives to nonrenewable resources such as coal, oil, and natural gas that do not replenish themselves, and are environmentally destructive. It's crucial to gain specialized expertise. Focus on understanding the electronic components that are vital for renewable energy systems, such as inverters, which convert direct current (DC) from solar panels into alternating current (AC) for use in homes and businesses. Familiarize yourself with energy storage systems, ...
