ERRANT: Realistic emulation of radio access networks [PDF]

Computer Networks, 2020
Mobile networks have become ubiquitous, but running experiments on them is expensive and hard, given their complexity and diversity. Emulation can be the solution, and, with ERRANT, we offer a realistic emulator of mobile networks based on a large measurement campaign on European Mobile Network Operators.

A Dual-Polarized Multi-Sector Antenna Using Dielectric Image Lines for Millimeter-Wave Indoor Base Stations

IEEE Open Journal of Antennas and Propagation
A new dual-polarized multi-sector antenna for a millimeter-wave indoor base station (27.4-27.8 GHz) is presented. The proposed antenna consists of six horizontally polarized (H-pol.) and vertically polarized (V-pol.) end-fire antennas on a ground plane ...

Collaborative Beamforming Aided Fog Radio Access Networks

IEEE Transactions on Vehicular Technology, 2022
The success of fog radio access networks (F-RANs) is critically dependent on the potential quality of service (QoS) that they can offer to users in the face of capacity-constrained fronthaul links and limited caches at their remote radio heads (RRHs).
