Offers the benefits of Flat IP architecture Single architecture supports Residential, Enterprise, and Metro cell CPE Small Cells Coverage and Capacity Basics
Macro + Small Cell Coverage Mobile Service Coverage Capacity Need Withoutdedicatedenhancement With dedicated enhancement In-building coverage and capacity rarely go hand-in-hand 5 Small Cells Layered Networks for Capacity and Coverage
3G Macro Capabilities Highly mobile users,non-real time data sessions (e.g.,, web surfing) 3G Macro LTE Macro Capabilities LTE Macro Highly mobile users,real-time data sessions, large data transfers 3G/LTE Small Cells Capabilities Small Cell Relatively stationary mobile users, real time data sessionslarge data transfers Small Cells Better Coverage and Capacity Distribution
Metro Cells provides Dedicated capacity where needed Increased Macro Capacity Coverage Vs. Macro Cells Macro Cells + Metro Small Cells Capacity Metro Cells are Small - may be deployed anywhere Versatile - may be used indoors or outin urban, suburban, and rural locations Cost-effective - many targeted small cells vs. one macro cell Average Throughput Average Throughput Vs. Cell Center like Throughput Macro Cells Macro Cells + Metro Small Cells Metro Cells Help the Big Ones Provide Higher Network QoS Managing categories of users
Access Control Depending on the Enterprise policy, one of the following modes can beselected: Public Macro Extension No ACL check. Any user which is allowed to roam on the macro network is allowed to access the open Femto cell Managing categories of users Only users listed in theAccess Control List (ACL)are allowed to access theFemto cell Restricted to configured users Similar to open access, except that in case of congestion, priority is given to registered users listed in the ACL. Priority given to the employees Introduction to Femto Groups Femto Group Support
Small Cell Group = Group of Cells for Extended Coverage A Femto group is used for private or public areas(small/medium enterprise, hotels, etc) wherethe individual AP coverage and/or capacity is notsufficient. Common LAC/RAC No LAU/RAU Common ACL No access control duringmobility Automatic configuration of the neighbouring listwith sniffer Up to 256 small cells 9 Introduction to Femto Groups Femto Group Characteristics
A Femto Group could contain as many as 256 Femto cells regardless of access mode. A Femto cell can belong to only one Femto Group All Femto cells belonging to a group shall have a set of common parameters A user can move inside the Femto Group In idle mode : Inside the Femto Group, there is no LAU/RAU (and therefore no Access Control) as a common LAC/RAC is used Access Control is not needed as long as there is a common ACL for the Group In connected mode Femto to Femto Handover within the Femto Group is supported Again, Access Control during HO is not needed as long as there is a common ACL for the Group In the solution, there is no extra signaling load on the CN due to Femto to Femto Mobility.

Small Cell UE raises noise floor of neighbouring Small Cell / Macro cell. Small Cell UE shrinks the UL coverage of the neighbours and may suffer degradation of the uplink throughput.

This feature allows the Small Cell AP to derive its NTP timing from theMeinberg NTP server. BCR2.4.1 release supports up to 2 NTP Meinberg servers just as it does forBrilliant / Symmetricom NTP servers. In addition the feature extends the current implementation which uses upto two NTP servers to be extended to up to five. The selection of the server is tried randomly and evenly distributed overthe available servers. There is no defined primary/secondary server, they have equal priority. The budget for NTP data exchanged between Femto AP and NTP server permonth will be similar to the budget for the Bti NTP server i.e. 200 Mbytes ineach direction, total 400 Mbytes per small Cell AP (assuming a wellbehaved network and that the Meinberg server is not overloaded). NTP algorithm supported in BCR3.0 will mean, in the worst case event (all APscold start) each Meinberg server will support a maximum 500 APs. Will support 1K APs typical load.
