Wireless Mesh Topology Tips
To maximise the performance of a mesh network the antennas on the WideSky® Hub devices should be adjusted so that they
are parallel to each other as shown in Fig 1. This is because most of the transmission energy is radiated perpendicular to the
antenna as shown in Fig 2.

Wireless Mesh Topology Tips
The environment and placement of wireless devices have a major impact on the performance of the system. Also consider
that moveable furniture and equipment will have an impact. Example a new metal storage cabinet in an adjacent room can
interrupt a previously reliable connection.

connecting to basements and cellars.
Avoid placing antennas inside metal enclosures such as steel distribution boards, use external antennas.

Wireless Mesh Topology Tips
The physical location of WideSky hubs (nodes) in a mesh relative to each other and the border router/s are critical to the
performance and resilience of the wireless network. Some general good design principles are:
• Ensure that there is more than one path from each node to the border router.
• Avoid single points of failure in the network, linear networks are particularly prone to this.
• Preferably keep data hops to less than 4, system latency and reliability can be compromised with larger numbers.
