2006 MikroTik MUM 2
Overview
• Seamless wireless roaming• MESH like network support• Secured and dynamic data communication
between AP’s
2006 MikroTik MUM 3
Requirements for MESH
• RouterOS v2.9.x with RSTP package enabled
• One or more Atheros chipset wireless cards for each router
• Antennas (Omni, sector, directional) for each band – 2.4Ghz and 5Ghz

Advanced options• Encryption (WPA-PSK/EAP) for AP-AP
communication• Segmentation of the MESH – different
band/frequency for each MESH segment• Use of WDS-Slave mode for automatic adjusting
the operating frequency to match Main AP’s frequency
• Using Static mode for WDS instead Dynamic to make specific MESH network layout
