Implementation FAQS

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 would require a full Health and Safety/Covid induction from a building manager/FM.  The University’s Managed Network Services (MNS) staff would 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 would be conducted. Ideally, we would like access to all areas within the building to produce a full picture of your wireless coverage.

It would not be recommended to do this within the same building, if possible. The two systems will work along side each other but there will be some performance impact particularly concerning roaming.

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 heatmaps are on a floor by floor basis. There are multiple views and one does so based on CLIENT reported data, not just what the AP output power is. This takes into account APs across floors

The ekahau surveys are definitely taking into account 3D space.

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

The project is covering all costs to 31 July 2022.  A cost model for the future is in course of preparation, and details will be shared here as soon they are available.
