The Easter Ross communities of Milton, Kildary and surrounding areas are set to receive better mobile coverage and improved internet connectivity.
A new 164ft tall tower has been developed at Milton in partnership with O2, which has now switched on 4G.
In addition to serving the local communities of Milton and Kildary, the facility will also cover 15 miles along the A9.
Wireless Infrastructure Group (Wig) has built and will operate the tower and has announced the big switch-on, ahead of the Convention of the Highlands and Islands at Millport today.
The new structure is located at a Scottish Water facility and is part of a successful and growing partnership between Wig and Scottish Water that has already delivered the infrastructure to enable 4G to more than 150 Scottish communities.
It has the capacity to offer access to all mobile network operators as well as other rural wireless networks.
Fergus Ewing MSP, Cabinet Secretary for the Rural Economy and Connectivity, said: “It is hugely encouraging to see the difference these projects are making to rural connectivity across Scotland.
“Investment in higher capacity mobile infrastructure is key to bringing digital services to the communities of the Highlands and Islands.
“We are working to deliver improved mobile connectivity across Scotland.”
