7.2 Limitations

Full concurrency is not supported due to hardware limitations (the need for two PHYs and two radios).

The performance is split between the roles and reduced due to the contact switch and role protection time.

The WiLink8.0 device supports up to two WLAN roles running simultaneously, as seen in Table 19.

Table 19. Supported Multi-Role Combinations

Role STA AP P2P CL P2P GO
STA X V V V
AP V Same Channel V Same Channel
Mesh Same Channel Same Channel X X
P2P CL V V X X
P2P GO V Same Channel X X
  • Dual AP mode must be started or stopped statically.
  • While operating as DFS master, no scans are allowed. This means MR combinations of DFS master with STA or with P2P are not supported.
  • While operating as AP and P2P-GO (same channel) the P2P-GO channel should not be explicitly given and the channel synchronization is automatically.
