Currently, the need of high speed data rate services at mobile group vehicles moving at high speed has been increased. In ETRI (Electronics and Telecommunications Research Institute), we have been designing and developing a new wireless mobile backhaul system, Mobile Hotspot Network (MHN) system, which can support over 1Gbps data rate services for mobile(More)
In order to migrate toward 4G, studies on 3G LTE(Long Term Evolution) have been announced recently in the 3GPP(3rd Generation Partnership Project) and standardization is under way. Therefore, 3G LTE(Long Term Evolution) systems have been designed and developed over many countries. We also have been developing a 3G LTE testbed system at ETRI. 3G LTE system(More)
Recently, data usage of end users are deeply increasing in the moving vehicles, such as subway, train and bus. In order to meet this requirement, we are designing and developing the 5<sup>th</sup> generation mobile backhaul system in ETRI (Electronics and Telecommunications Research Institute). This system is MHN-E (Mobile Hotspot Network &#x2014; Enhanced)(More)
