Repeater units are designed to receive signals from a donor site, amplify and rebroadcast the donor sites signals into poor coverage areas or to extend the coverage range of the donor site. Repeater : These repeaters are bi-directional and do not translate frequency and subsequently are limited in output power and gain. Repeaters provide between … Read more
Here I write down which point to tack care during antenna installation which including Wind load, Work Temperature and Humidity and Camouflaged Antenna Scheme for Sites Wind Load The antennas are usually installed on high buildings or towers. In the littoral areas, the wind is strong with high speed, so the antennas are required to … Read more
Here I write down some passive characteristics definition for antenna which include Port Isolation, Power capacity, Input Port of Antenna, Passive Intermodulation (PIM) and Dimensions and Weight of Antenna. For multi-port antennas, such as dual polarization antenna and dual band dual polarization antenna, the isolation must exceed 30 dB when the Rx port is the … Read more
Understanding the current subscriber behavior and trends is a valuable guide for a product manufacturer and operator of the capital investment. In this post a few key observations will be shared via the Internet and existing wireless high speed data transfer. The first observation is: 1. Increased bandwidth translates into more demanding users. This is not … Read more
In particular, for application indoors, it is often desirable to predict the service area of a repeater or microelement based power CPICH. In the repeater installation and commissioning, CPICH power can be determined by measuring the output (or input) Ec / No and the received signal. The objective is to estimate the range of the … Read more
