Femtocells – Current Challenges Femtocells are rapidly gaining momentum in the market... ...and so are the challenges!
Femtocells – Current Challenges Radio Current challenges stretch acrossQoS / QoE Security many aspects: • Technology Femtocell • Regulatory Challenges • BusinessNetwork / Standards, • Market Device Inter- Mgmt operability ...and from R&D to Integration, Eco- Deployment and System Operations
Interference at the Heart of Radio related Challenges Radio• Indoor coverage key to • Operating Femtocells QoS / QoE Security Femtocell Challenges Femtocell proposition on dedicated band Network / Device Mgmt Standards, Inter- operability• 70% of calls indoors – leads to shortage Eco- System vs. 2% of buildings Spectrum • UMTS 900 as viable with indoor solution option Keywords include: 64QAM, MIMO, Adaptive Signal Processing, Tx/Rx Diversity, Cooperative Comms, Beamforming, Coverage Interference Throughput Cognitive Radio Our Verdict:• Technology evolution • Femto-Femto Self- and new capabilities Optimization 4G will help addressing• Complex algorithms to Complexity • Femto-Macro issues with Throughput, address radio dedicated bands for Interference, and – performance and Residential, impact on depending on licenses – interference issues Metro / Enterprise Spectrum, at the cost of increasing Complexity
Recent Headlines emphasize need to ensure Security Radio QoS / QoE Security Femtocell Challenges Network / Standards, Device Inter- Mgmt operability“Femtocells wilt “UMA FemtoCell Eco- Systemunder 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 phonesfraud” 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.
Standards – Interworking – Interoperability: Vital for the success of Femtocells Radio QoS / QoE Security • Seamless H/O Network / Femtocell Challenges Standards, • IMS integration Device Inter- Mgmt operability Macro- • Network / Device Eco- System Network Management The nature of Femtocells requires co- • No H/O existence and WiFi • Need Dual Stack: interfacing with • Complexity (UMA) • Higher Cost various other • Less Battery Life technologies.
