Advantages And Disadvantages Of Power Line Communication

* There may be a barrier to normal methods of communication like a longer distance or a noisy environment.

Transmission interferences: Weather, terrain, and the range from the nearest signal point can all interfere with signal reception. Reception in tunnels, some buildings, and rural areas is often poor.

and difficult to intercept also this transmission can share a frequency band with many types

The transactional communication model is used daily in my household. Although, the messages are not always successfully sent nor received along the channels due to major amounts of noise. It is hard to

The health of RF-EMFs stared January 1990 when a cell tower was buildup 800 feet from a family that had a dairy farm in Mansfield, Ohio. By the fall, the cattle herb that pastures near the tower was sick, and the children that lived near the tower begin suffering from bizarre skin rashes, that’s when the owner of the farm contacted an environmental protection agency scientist named Carl Blackman. He’s was an expert on the biological effects of radiation from electromagnetic fields (EMFs)-the kind of radiofrequency EMFs (RF-EMFs) by which all wireless technology operates, including not just cell phones towers and cell phones but also Wi-Fi hubs and Wi-Fi –capable computer, smart utility

The power system is installed within 5 electrical substations with emergency equipment, generators, medium voltage panels and transformers.This installation makes the power distribution to Petrobras Headquarters UOBS, which currently controls its offshore operation units (oil platform).The power system is divided into the following subsystems:

The last major step in connecting your home to the grid is the signing of an interconnection agreement with the utility

-The Federal Communications Commission, the Environmental Protection Agency, the National Institute of Occupational Safety and Health along with other agencies have been investigating the effects radio frequency can cause.

A lightning strike to the power lines local to your home can send a powerful

With cell phone usage increasing, many individuals have become concerned about the health effects of radiation from cell phones and cell phone towers. In recent years, various studies have been conducted to determine whether the radio frequency waves from cell phone towers have a detrimental effect on health. Current research has yielded inconsistent results regarding the effects of radio frequency waves, and while the World Health Organization does not view radio frequency waves as serious risk, more research needs to be done in order to be certain (USDA, 2009).

If the communication was not properly channeled, it creates barriers or noise interference which hinders the communication process making the message unclear.

electrical appliances will be on in one room and OFF in another room. This creates a big disturbance
