Circuit/Packet | Packet | The existing 3G W-CDMA standard will be replaced in 4G by VSF-OFCDM and VSF-CDMA. VSF-OFCDM allows extremely high downlink connections‚ both indoors and outdoors. VSF-CDMA provides high-efficiency‚ high-speed packet transmissions for the uplink. The 4G adoption of concatenated FEC (Forward Error Correction) will allow much larger data packets to be transmitted and at the same time reduce the bit error rate. This will increase the overall data through-put. One of the

1 What are two reasons for physical layer protocols to use frame encoding techniques? (Choose two.) to identify where the frame starts and ends* to distinguish data bits from control bits* to reduce the number of collisions on the media to increase the media throughput to provide better media error correction 2 Which statement is correct about multimode fiber? Multimode fiber commonly uses a laser as a light source. Multimode fiber cables carry signals from multiple connected sending

TERRESTRIAL MICROWAVE COMMUNICATION SYSTEM DESIGN DESCRIPTION OF THE MICROWAVE BEAM: 1. The microwave beam behaves like a light beam and it tends to follow a straight line and azimuth. 2. The changes on temperature‚ pressure and relative humidity tends to refract the microwave beam. So it will follow on a slightly curved path. The radio horizon exists. 3. It is diffracted when grazing over an obstacle. A small shadow area created when some of the energy is redirected. 4. The beam

message receipt. Third‚ protocols provide a basis for error checking and measuring network performance. This is done by comparing measured results against expectations. For example‚ performance measures pertaining to storage access times‚ data transmission rates and modulation frequencies are critical to control the network’s function. Thus‚ the identification and correction of errors depend on protocol standards that define acceptable performance. Fourth‚ protocols promote compatibility among
