Recent Headlines emphasize need to ensure Security Radio QoS / QoE Security Femtocell Challenges Network / Standards, Device Inter- Mgmt operability “Femtocells wilt “UMA FemtoCell Eco- System under attack” “Security Issues in Security Concerns” Next Generation Mobile Networks: “Femtocell Security: LTE and Femtocells” Capturing phone “Insecure [...] numbers of passers-by” femtocells allow “MAJOR HACK: [...] eavesdropping, call femtocells open phones fraud” up to intercept” • Recent headlines highlight security concerns Our Verdict: around Femtocells – whilst some are biased or exaggerated, others emphasize the need to address Security across the entire network. Such Security concerns are particularly • The impact on Residential Femtocells is limited, applicable to new whereas Metro / Enterprise deployments will technologies – and 4G require additional effort – to meet the security Femtocells will be no expectations of mobile networks and keep the exception. advantage over other technologies such as WiFi.
