Technical FAQs 4

What events does the S11 interface application initiate from an Mme node?

The S11 Interface Application initiates the following events from an MME node: The CableFree LTE platform is complete and includes Base Station, EnodeB, Remote Radio Head (RRH), Base Band (BB) RF Controller, Evolved Packet Core (EPC) and CPE devices to build complete 4G LTE networks.

What is a S11 interface?

The S11 interface connects the MME to the SGW for signaling in the control plane. Protocols Used: GTP-C (GPRS Tunneling Protocol – Control plane): Used for session creation, bearer modifications, and releases. UDP/IP: Underlines transport and network addressing.

What is a ground BS antenna?

The paper introduces a ground BS antenna design for the 5.9-8.5 GHz band. The main contributions include wide-band, high-isolation antenna array concept for the ground BS antenna, along with an analysis of how the antenna array dimension affects the signal-to-noise-and-interference ratio and throughput in ATG systems.

What is S1 interface?

The S1 interface has two parts: a) S1-MME (Control Plane) Connects the eNB to the Mobility Management Entity (MME). Protocols Used: S1-AP (S1 Application Protocol): Manages UE context, bearer setup, paging, and handovers. SCTP (Stream Control Transmission Protocol): Ensures reliable transport for signaling messages.
