Abstract:

Fifth Generation (5G) Millimeter Wave (mmWave) cellular networks are expected to serve a large set of throughput intensive, ultra-reliable, and ultra-low latency applications. To meet these stringent requirements, while minimizing the network cost, the 3Generation Partnership Project has proposed a new transport architecture, where certain functional blocks can be placed closer to the network edge. In this architecture, however, blockages and shadowing in 5G mmWave cellular networks may lead to frequent handovers (HOs) causing significant performance degradation. To meet the ultra-reliable and low-latency requirements of applications and services in an environment with frequent HOs, a Fast Inter-Base Station Ring (FIBR) architecture is described, in which base stations that are in close proximity are grouped together, interconnected by a bidirectional counter-rotating buffer insertion ring network. FIBR enables high-speed control signaling and fast-switching among BSs during HOs, while allowing the user equipment to maintain a high degree of connectivity. The FIBR architecture efficiently handles frequent HO events in mm Wave and/or Terahertz cellular systems, and more effectively satisfies the QoS requirements of 5G applications.

Abstract:

Aspects of the subject disclosure may include, for example, a wireless framework for delivering TV services. The wireless framework can include a mix of wireless access technologies (e.g. Satellite, WiFi and/or LTE overlay links). One or more aspects of the subject disclosure include injecting TV content into the network at a few locations (e.g., residential locations) using satellite antennas (e.g., satellite dishes). The content is then further distributed to other homes using a house-to-house WiFi network and/or via an overlay LTE network. Other embodiments are disclosed.
