2. Inter-cell Coordination Evolution Strategies CA improves network capacity by broadening frequency bandwidth, whereas inter-cell coordination technologies do the same task by enhancing frequency efficiency. Inter-cell coordination is designed to manage radio resources more efficiently by having cells in different sites share user and/or cell information with each other. Inter-cell coo...

In the past two years, some new technologies have been introduced in Korea, apparently increasing broadband Internet speeds 3~5 times faster, from 100 Mbps to 300~500 Mbps, instantly. It certainly is fascinating in that such speed improvement was achieved without the hassle of re-cabling construction in apartment buildings. Because 100 Mbps had seemed unbeatable for almost a decade, this sure w...

Today, we will learn about CoMP, an inter-cell cooperation technology in LTE-A, since we learned about ICIC and eICIC in the previous posts. At an early stage of LTE/LTE-A, offering high speed is the most important marketing point for operators. However, as LTE subscribers and traffic grow, satisfying users with high Quality of Experience (QoE), for example, by improving user throughputs at cel...

Enhanced Inter-Cell Interference Coordination (eICIC) As noted in the previous post about ICIC, we will find out about enhanced Inter-Cell Interference Coordination (eICIC), an interference control technology in LTE-A in this post. In LTE/LTE-A, one key challenge for operators is that they have to increase network capacity to keep up with fast-growing traffic. Especially, crowded areas in m...
