A method of selecting a route for wireless communication between a first node and a second node in a wireless communication system comprising a physical layer where a cyclic prefix and at least one further parameter apply, the method comprising: evaluating a plurality of possible routes (R1, R2, R3, R4) from the first node to the second node, at least one route (R2, R3, R4) of the possible routes (R1, R2, R3, R4) including a third node (3, 4) between the first and the second node, wherein said at least one route includes at least two links (L13, L14, L32, L42, L34), said evaluating comprising: selecting parameter settings for each link (L12, L13, L14, L32, L42, L34) of the possible routes (R1, R2, R3, R4), which includes the substeps: - selecting the length of the cyclic prefix for the link in view of a first communication quality criterion for minimizing or avoiding inter-symbol interference; - evaluating combinations of the selected length of the cyclic prefix and different settings of the at least one further parameter of the physical layer, wherein the evaluating includes estimating the latency of the link; and - selecting the parameter settings for the link that have lowest estimated latency, the method further comprising: selecting the route that has the lowest latency among the possible routes including adding together the latency for each link (L13, L14, L32, L42, L34) of the route (R1, R2, R3, R4) and, for each route (R2, R3, R4) having a third node (3, 4) between the first node and the second node, adding the processing time of the third node (3, 4) of the route, characterized in that the evaluation substep includes determining a packet error rate for the combinations and discarding such parameter settings that in combination with the selected cyclic prefix do not fulfil a packet-error-rate threshold. evaluating a plurality of possible routes (R1, R2, R3, R4) from the first node to the second node, at least one route (R2, R3, R4) of the possible routes (R1, R2, R3, R4) including a third node (3, 4) between the first and the second node, wherein said at least one route includes at least two links (L13, L14, L32, L42, L34), said evaluating comprising: selecting parameter settings for each link (L12, L13, L14, L32, L42, L34) of the possible routes (R1, R2, R3, R4), which includes the substeps: - selecting the length of the cyclic prefix for the link in view of a first communication quality criterion for minimizing or avoiding inter-symbol interference;
