Each Access Point (AP) should take no more than 15 minutes to replace. Any noise is minimal, as there will be no drilling or hammering required.

The Wi-Fi service will experience short drops of up to 15 minutes in a given area and therefore it is recommended that a wired connection is used during this time (wired connections will not be affected). We will provide suggested text about this, for you to circulate or repurpose, for people who are likely to be on site during the day. Staff or students will be able to remain in the building.

Contractors will require a Health and Safety/Covid induction from a building manager/FM.  The University’s Managed Network Services (MNS) staff will work with the contractors to test and sign off the installation.

Around two weeks after your installation at a date/time agreed with you, a post-installation radio frequency survey will be conducted. Ideally, we would like access to all areas within the building to produce a full picture of your wireless coverage.

Yes, we will install to new mounts, as long as they are clearly shown on a floor-plan and have a network cable ready to connect to the AP.

It is not recommended that the install takes place over more than one day within the same building.  The two wireless systems will work alongside each other, however users may experience an impact on performance due to roaming issues in certain situations.
 
All new APs must be pre-configured and fitted to the mounting brackets by Managed Network Services or a contractor working on their behalf.

Data sheets for each of the Juniper APs are available on this Juniper webpage.

We will be replacing the existing Cisco APs as follows:

For all APs being deployed during the COWLSHUR project, a minimum POE standard of 802.3at (also known as POE+) is required for all APs to operate correctly. We highly recommend that the ITSS check their switches to ensure that they also have the power budget to support total power draw of APs connected to them. For technical details on the APs please see the FAQ about AP Hardware.
 
For some particular AP models they can operate at the lower power standard of 802.3af, however some will not operate at all. It is so important that we run at the correct power that the Project is offering to supply POE+ rated injectors where POE+ isn’t available from the local switch. Note that each POE injector will require mains power.
 
In terms of Ethernet speed the Mist APs support up to 2.5Gbps. We would recommend that switch ports connected to APs support 1Gbps as a minimum but it is accepted that this may not always be possible. If you are aware of any AP that will only be operate at 100Mbps, please make sure to let the Project Team know during the Technical Conversation in preparation for your site install. Note an AP running on 100Mbps will be significantly constrained in forwarding client traffic.

Juniper Mist is able to create heat maps based on a floor by floor basis. This view is based on data reported by the clients, not just on what the AP output power is.

The remediation report you will receive provides a survey performed using Ekahau software, which is able to give a 3D picture by detecting signal bleed through floors and ceilings within a building.

This will remain as it is now, via a local VLAN to your FroDo.

This is an indicator that the user is likely using a Windows based device with an Intel chipset that has outdated drivers, meaning it is not compatible with Wi-Fi 6 (aka 802.11ax).

Apple, Android, Chrome or other non-Windows based devices are NOT affected.

Full details of the affected drivers and adaptors are available in a dedicated Intel support article

For Dell devices, IT Services has already rolled out updated drivers to all of the affected Windows systems it manages, and has set up a wiki page to help ITSS colleagues address the issue on any Dell devices that they support.  

For non-Dell devices, Intel has included a fix for this issue in its latest drivers for its wireless adaptors. You can get more information and resources from the Intel support page dedicated to this issue and the Intel Driver & Support Assistant

  • Wireless standards 802.11a, 802.11g, 802.11n, 802.11ac, 802.11ax are fully supported by Mist.
  • The 802.11b standard is not supported by the Mist solution

All clients must be currently supported by their manufacturer, as changes to authentication and security are frequently pushed out to combat vulnerabilities.
