AirVelocity: High Performance Indoor LTE Small Cell
AirVelocity is an indoor small cell with a wireline backhaul connection (RJ45 and SFP ports), usually over Ethernet or fiber. It can be mounted on walls and ceilings, and fitted with different antenna types (directional or omni). It supports LTE-A (FDD or TDD) and an optional carrier-grade WiFi AP (802.11n concurrent with 802.11ac).
It supports frequency and time synchronization via Network Listening (air sniffing), 1588v2 PTP, Clock over GPON, and a GPS receiver which can be connected to an external GPS antenna. Highly accurate frequency synchronization using SyncE can improve 1588v2 accuracy, and can increase holdover times in case GPS signal or 1588v2 packets are lost.
Since AirVelocity is located indoors close to the users, the cellular signal quality is very high, and users enjoy a great user experience. This offloads the Macro cell, enabling it to serve more suitable users (mainly outdoor), thus increasing spectrum efficiency. Users connected directly to the Macro cell suffer from poor user experience, since the cellular signals must travel long distances, and are obstructed by buildings and external walls.
AirVelocity is connected to the LAN via a wireline backhaul connection. An IPSeC tunnel ensures secured connectivity with the carrier network (EPC) for LTE traffic. AirVelocity also supports LTE-WiFi Link Aggregation (LWA), and in this case all traffic passes through the EPC using a secured IPSeC connection.
