Active Phased Array Principle of Operation
• Transmitter - combination of spatial power combining and beam forming enables implementation in VLSI RF (CMOS, SiGe etc) : 20*Log(Ne)
• Receiver - combination of power combining and beam forming improves overall NF of the receiver system : 10*Log(Ne)
• Tx and Rx antenna gain increases by F2 for constant antenna aperture

Background and Motivation
• Demand for on-train passenger wireless services projected to exceed 1Gbps per train by 2025
• Based on ≥50% of 1,000 passengers consuming >2Mbps each; except this is not the only requirement! (e.g. CCTV)
• Current generation of wireless track-to-train solutions do not have sufficient capacity for future demand: Wi-Fi up to 500Mbps and 4G 200Mbps
• Use of mmWave spectrum proposed by OFCOM in their report below
• Ofcom’s report to UK Government to improve rail connectivity, c. Oct 2018
2G
3G
4G (12Mbps)On-train throughput: <<10Mbps/MNO
4G/LTE-A (>50Mbps)
5G (200Mbps)
Rail 5G mmWave (Now)On-train throughput >>1Gbps
We need 150Mbps for customers before considering the wider
commercial opportunities.By 2025 this will be >1Gpbs, so the
requirement will be 2-3Gbps
