Added new hardware at geluidsnet nodes

  • USB dongles to VLAN switches
  • New power supplies
  • Removed unused unmanaged switch for webcam setup
  • Secured UTP cable at Balcony
  • Two LiteBeam antennas
  • Retored connection to meetunit of geluidsnet themself

Note: Link is dual used for BSP-OV Pilot so special VLAN configuration setup
at RB260GSP is installed. VLAN102 is bridged making a large pass-through link.

PoC: Secure Wireless Interlinks with password to avoid clients to connect to them
  • Property svn:executable set to *
  • Property svn:keywords set to Id
