Cat 6 is what they offer but you may request for cat 7. Cat 5 is outdated and doubt if they can provide this for you.
You may also consider utilising access points (speak to them about this) to boost your Wifi signal for steel frame homes.
Thanks a lot. Do they charge for every data point? If so any idea how much
Access point- u mean roof access point ?
Yes there is a unit cost for data points. I was charged $860.00 for 6 points and $750 for Wireless Access Point (WAP) installation.
A wireless access point is a device that creates a wireless local area network in a steel frame house better than the wireless router your service provider provides. An access point connects to your service provider router via an Ethernet cable, and projects Wi-Fi signal to the rest of the house for mobile devices. It is usually mounted in the ceiling not the roof.
