Wireless Network - ActionTec Screenbeam 960 Deployment Manual

3.2 Wireless Network

802.11ac wireless access points (WAPs) networking is strongly recommended. 802.11n
WAPs are the minimum required for ScreenBeam to work correctly.
2.4GHz/5GHz support for WAPs is strongly recommended.
ScreenBeam 960 does not support Dynamic Frequency Selection (DFS) channel for wireless
connectivity. Dynamic Frequency Selection is required in the 5GHz band so that wireless
connection on DFS channels automatically switches when in use by other applications such
as radar. Ensure wireless APs are configured to support non-DFS 5GHz (recommended)
and/or 2.4GHz band as follows:
2.4GHz – Channels 1, 6, 11 only
•
5GHz (non-DFS, 20MHz wide channels) – Channels 36, 40, 44, 48, 149, 153, 157,
•
161 only
5GHz (non-DFS, 40MHz wide channels) – Channels 36, 44, 149, 157 only
•
To avoid connectivity issues, the following practices are strongly recommended:
Do not use overlapping channels for WAPs in adjacent rooms, including between
•
floors. Alternating channels used helps ensure reliable connectivity.
Use 5GHz whenever possible versus 2.4GHz, as 5GHz signals cannot penetrate
•
through walls to adjacent rooms as well as 2.4GHz signals can, 5GHz channels
have better separation, and 2.4GHz is used by more devices.
Minimize use of unauthorized or unmanaged wireless devices by policy (e.g.
•
Bluetooth, wireless game controllers, wireless video cameras), especially those
using the 2.4GHz band.
Avoid use of 802.11n for clients and WAPs whenever possible, as 802.11ac is more
•
spectrum efficient than 802.11n and will give a better presentation experience.
If connectivity issues persist, contact a qualified IT professional to conduct a wireless
survey for recommendations on improving Wi-Fi connectivity.
As discussed above, network switches may not pass mDNS traffic across the network and
block that traffic at switches and routers. If unblocking the port is infeasible, solutions exist
that can cache mDNS broadcast requests and send them out of band to all WAPs in a
network without the corresponding bandwidth burden. Consult the documentation from
the WAP manufacturer or network vendor on how to deploy such solutions.
