Last week we conducted a webinar – "Breaking the Form Barrier – Evolution of LTE & Enterprise Femtocells" – that generated a lot of incisive questions about the implementation challenges and solutions for next generation femtocells. We received more questions than we were able to answer in the time we, so the Aricent experts that led the webinar, Sanjiv Kapur and Siddhartha Bhakta, have gone through the unanswered ones with responses below.
Q: How will CDMA be incorporated in next generation femtocells?
A: LTE and other next generation telecommunication technologies will need to co-exist with older technologies such as UMTS, CDMA and GERAN, etc. Deploying stand-alone solutions supporting individual technologies can be prohibitively expensive for both operators and subscribers.
Multi-mode femtocells - capable of supporting multiple technologies simultaneously - provide a solution for deploying these technologies to ensure that expenses are kept under control. These femtocells will provide support for LTE and one or more older technologies based on the operator’s requirements.
Q: How can interference be reduced when macrocells and femtocells need to use the same carrier?
