| Summary: | Currently, Femtocell technology emerged for cellular wireless networks, which has rapidly engrossed cellular industry. The principle of femtocell to the mobile operators is to reduce cost and improve signal quality in indoor coverage which is also considered a possible path to the fixed-mobile convergence (FMC) goal. Femtocell extends network coverage and delivers high-quality mobile services inside residential and business buildings through broadband network i.e. ADSL. Femtocell access point (FAP) or home
base station (HBS) intends to serve small number of users i.e. 4 users and covers about 30 meter square similar to existing WiFi access points. However, femtocell introduces
new challenges to the telecom industries in terms of handoff between femto and macrocells, interference management, localization and synchronization. Among all 0 f
these challenges, synchronization is considered corner stone for proper working for femtocell. The problematic issue in femtocell synchronization is that all the data and
control traffics travel through IP broadband network. The IP broadband network is usually owned and managed by third party and not by the mobile operator, which is
complicated the synchronization. Unsynchronized FAPs may cause harm interferences and wrong handover dictions. In this study we investigate and overview the current
femtocell synchronization techniques and compare between them. Possible improvements and recommendation for each method is identified. Future research areas and open issues were also discussed. |
