In view of the HL-LHC parameters, the present and the future RF systems for the LHC are reviewed with a focus on technological aspects. This paper will describe the preparation and the test programof the SPS beam tests with crab cavities. Some aspects related to the integration of the crab cavity RF system in the LHC and the potential impact of the crab kissing scheme are addressed. The mode of operation for the 400 MHz accelerating RF system with HLLHC beam currents and the associated issues are briefly outlined with possible improvements to the ACS system. Finally, the use of a harmonic system both at 200MHz and 800MHz for bunch profilemanipulation and the associated technological challenges are described.
