Study On Construction Of TD-LTE Indoor Distribution System

Mobile data traffic growth is and will continue to be driven by large increases in the number of mobile subscriptions、internet of things and intelligent terminals。High percent data service occurred in door by statistics。The indoor distribution system has better wireless coverage and capacity for those large buildings。Four different type networks will be online together in telecomm operator network because of construction of TD-LTE。So the factors should be considered during the construction of indoor distribution system, such as service need, network performance, construction difficulty。The article introduced the whole construction process of TD-LTE indoor distribution system。Based on this, different construction modes were compared by service environment and capacity。Then for the problem of interference between co-indoor distribution system, it introduced the interference theory and analysis methods。Isolation index or isolation distance were calculated for two types of indoor distribution system。Then by simulation software it analysed interference signal intensity and data throughput rate。Finally, several methods were provided to avoid the interference of indoor distribution system between TD-LTE and other mobile systems。...
