A solution has been found that could see officers deployed inside West Ham's London Stadium for Wednesday's EFL Cup tie against Chelsea.
Matches at the Hammers' new stadium have been affected by crowd trouble this season and next week's tie is deemed a high-risk fixture.
Police have not been present so far because of lack of radio facilities.
But for this tie they will be able to communicate with a control vehicle on the stadium perimeter.
The Metropolitan Police Service (MPS) says it hopes the necessary Airwave radio communication system is in place inside the stadium by February 2017.
