Abstract :
WiBro (Mobile WiMAX) is a broadband wireless internet service supporting for fixed, portable and mobile users, but enhancement of service quality in indoor environment is still necessary. WiBro femtocell is developed to expand cell coverage, increase system capacity and offer various multimedia service with high throughput in indoor environment. Three types of femtocell are designed according to the class of application environments, such as home, SOHO and enterprise. The functionalities of radio access station and access control router are integrated in Home and SOHO femtocell. Inter-operational test with mobile terminal and performance evaluation are carried out and research results on related technical issues such as synchronization and auto-configuration are also described.
