Cisco Meraki Indoor Dual-band Omni Antennas, 6-pack

The Dipole antenna is ideal for low ceiling installations where wall
penetration or extended reach are important. Some example uses
are low-density deployments like schools and hotels to provide
basic low-performance connectivity. These types of best effort
deployments usually have APs installed in the hallway to cover
adjacent rooms.
