Margin sites intrusive noise levels due to an increase can be considered as If sites were spaced closer together than position using the same frequency The thermal noise floor. In other words, the system is interference limited as Opposed to limit noise. Often a site link budget maximum range is used to evaluate the process. … Read more
LTE access network and E-UTRAN, the network comprises a eNodeBs, as shown in Fig. For the normal user traffic (as opposed to transmission), there is no centralized controller in E-UTRAN, thus, E-UTRAN architecture is called flat. The eNodeBs are usually inter-connected together through an interface known as X2, and the EPC interface through S1 – … Read more
After completion of the design, installation takes place. For aesthetic reasons, the components of a closed system is often deliberately hidden. As a result, after installation, it is difficult to confirm or check them in full. Skill during installation, therefore, very important, because troubleshooting defective components is difficult. Perform a complete examination and sample testing … Read more
A DAS contains the same active components present in a DAS passive, with the addition of active devices such as amplifiers, repeaters or amplifiers bidirectional (BDAS) to amplify and / or radio signals shipping. This enables an active DAS to cover a much larger area of a passive DAS. Active distribution systems, however, are more … Read more
