8-meter Lattice Tower FOR Sure (IOM) Ltd AT Sure Site 25 King Edward Bay Golf Club Onchan Isle of Man Planning Application Supporting Statement DATE: 01/10/23 PREPARED BY: Alex Taylor Sure IOM Ltd
In 2006/7 Sure Isle of Man Limited (Sure) was awarded an Isle of Man (IOM) Mobile Operators Licence, issued by the Islands Communications Commission (CURA), to provide a mobile phone network and services to the Islands inhabitants and visitors. This service competes with the incumbent operator (Manx Telecom) and allows greater choice and competition for consumers and businesses.
The Sure Mobile Network is made up of multiple sites around the Island, these mobile sites use radio equipment to provide mobile coverage around the Island, this equipment includes mobile panel antennas, radio equipment and also transmission dishes that we use to link our remote sites back to our core network. All our sites then combined provide all Island coverage for our customers.
Sure, will endeavour whenever possible, to install its equipment on existing infrastructure or radio transmitters. The aim is always to minimise the visual impact of providing mobile phone network infrastructure.
Where this is not possible, and it is necessary to introduce additional telecommunications infrastructure, this supporting statement will justify why the infrastructure is required and demonstrate that the best possible design available for the site has been identified, always keeping visual impact and amenity a priority.
It will also help to explain the decisions which led to the specific location being chosen and will outline which alternatives were considered and discounted.
A variety of supporting information may be included with each application but ultimately Sures aim is to minimise the number of new structures and reduce the visual impact of the network, whilst providing sufficient signal strength to provide coverage for customers to take advantage of a range of Sures services.
For the avoidance of doubt: a mobile site, as referred to in this document, is a combination of equipment including cabinets, antennas, and structures, required to facilitate the operation of a mobile phone network.
The proposed development will consist of replacing the current 8 meter monopole with a 8 meter slimline lattice tower on the existing Sure mobile site located at King Edward Bay, Onchan.
We are also proposing moving the structure into the existing Sure compound on the site, this will assist with anti-climb protection as the compound is fenced off from public access, this will also reduce our footprint on the site by containing all of the Sure equipment into the compound.
The proposed structure will be capable of supporting multiple panel antennas, providing 2G,
The new proposed structure will also support smaller dishes known as microwave links used as transmission links for the site back to the Sure core network, the proposed design includes 1 microwave link, the size/location of the dish on the included drawings for this application are indicative until a final vendor decision has been made, final sizes will be confirmed with planning ahead of installation.
*MIMO, Multiple In Multiple Out, this is a protocol required for higher speeds and high capacity
The current structure is incapable of supporting the newer equipment that is required to support the next generation of mobile technologies, this is due to several factors such as size/weight of new equipment, wind loading on the current structure and also available space on the structure – currently it is only capable of supporting 2 mobile panels and 1 microwave link, we would like to increase this to potentially support additional mobile panels and microwave links and also to allow us to mount RRHs on the structure to improve the mobile service in the area.
The new proposed structure will be built on the existing Sure mobile site at King Edward Bay Golf Club, current structure is highlighted in red, the yellow highlighted area shows where we propose to move the structure to, within the existing Sure compound where we currently have our ground equipment located (radio cabinets & power cabinets).
The proposed development is an upgrade of our existing site, as the existing structure can no longer support newer mobile equipment it will start to impact the network in the local area. The physical structure of the current monopole is not capable of supporting next generation antenna. The failure to develop this mast will severely impact the ability of Sure to support next generation technologies development in the area.
The other option considered was a site sharing opportunity with MT as they have a monopole (fake tree disguised) at Bibaloe Beg Farm, however this structure has been discounted due to it’s location as it would massively impact the Sure mobile network in the area as it is a significant distance between the current Sure site and the MT site, along with the location the structure itself is not designed to be a dual user monopole, so it would not be able to support both operators radio kit on the structure.
We believe that the visual impact of the proposed new structure will be minimal, due to the structure type. Having opted for a slimline lattice we think that we can increase the network capacity in the area using a more versatile structure without a negative impact on the landscape.
Current Sure monopole, this structure will remain in place as the Golf Club use it as floodlight structure for the car park.
Current Sure compound where we are proposing to build the new structure, the compund is where we will also locate any mobile cabinets and our power cabinet for the site, the area is fenced off from public access.
Examples below of slimline lattices that are currently deployed on a few Sure mobile sites around the Island.
The proposed equipment cabinet will be used to house mobile equipment that is required to support the radio equipment that is located on the structure with processing cards and site transmission equipment, there will also be power equipment within the cabinet, this will include battery back up in the event of power outages in the area to ensure the mobile coverage is maintained.
| Number of Cabs | 2 |
|---|---|
| Cabinet Height | 1800mm |
| Cabinet Width | 600mm |
| Cabinet Depth | 600mm |
| Cabinet Colour | Neutral (options to paint to fit surroundings if deemed appropriate) |
Along with the mobile equipment cabinet, there will also be a meter cabinet where the Manx Utilities mains incoming supply for the site will be located along with the electricity meter for the site power usage, there will also be a generator input for additional power back up for the site.
The following antennas have been selected for the new proposed structure, the visual impact of the antennas should be minimal, due to the structure type and the neutral colour of the panel antennas, the antennas can also be painted to suit the surroundings if required.
Antenna Type
2.0m Panel Antenna
Antenna Height
1998mm
Antenna Width
469mm
Antenna Depth
205mm
Antenna Frequency Ranges
690 – 960 MHz 1695 – 2690 Mhz
The current Sure mobile site at King Edward Bay is limited on network enhancements due to the current structure type as the current monopole cannot be modified to take any additional equipment/load.
Antennas and RRHs (radios) sizes/weights are changing, some are getting wider and also heavier, this will be an issue for us on this site as we will be unable to install this equipment on the current structure as it will exceed the windload limits for the structure, this would massively impact mobile service in the area in the future.
Mobile equipment in the past has been a combination of tower mounted kit (antennas) and ground kit (radio cabinets to house radio cards), as we progress into next generation equipment, the equipment is moving towards being tower mounted (RRHs – Remote Radio Heads), this is to enable improved network performance as the kit being located near the antennas will maximise our MIMO potential from the radio kit, if we do not upgrade the existing structure we would not be able to mount these RRHs near the antennas, thus impacting the level of service we can provide from the site.
The proposed new structure will have significant advantages over the current monopole. We will be able to mount the antennas slightly higher on the structure and we will also gain space for potentially installing additional antennas to enable us to optimise network capacity to the residents of Onchan, ensuring maximum performance potential is being achieved from the mobile site.
Another advantage will be the structural strength of the new tower, it will be built to support next generation mobile equipment to improve the network capacity and capability in the area, it will also be a climbable structure, this is a major advantage as it allows easy access for Sure RAN Engineers to the equipment mounted on the structure in case of any maintenance or faults on site.
These improvements directly support the Isle of Man Governments ‘Island Plan’ which has a vision of a digitally connected Island, that supports a tech enabled and future ready jurisdiction, Onchan will benefit from greater network capacity and service due to these improvements to the Sure mobile site.
Coverage Maps
Health & Safety (ICNIRP)
This site has been designed in accordance with the current mainland UK Cellular operator’s guidance for both Occupational and Public ICNIRP compliance. Our design team is satisfied that this site design complies with the above guidelines and therefore a signed ICNIRP certificate is enclosed with this application.
communications systems to satisfy residential and business demand and the impact that the necessary infrastructure will have upon the environment. Measures which may help to achieve a satisfactory balance will include a presumption against visually intrusive masts in sensitive landscapes, the encouragement of mast sharing by different operators, and the removal of redundant infrastructure. Exceptions to this policy would need to demonstrate a strategic national need, which cannot be otherwise secured by mast sharing or alternative locations.”
Sure IOM Ltd believes the proposed installation complies with the island’s policies and strategies above.
To summarise, we consider that this application will offer the best available solution to the enhancement of mobile service on the Sure network in the area.
The current mobile site is in the optimal position to provide coverage to Sure customers in Onchan, alternative sites would not provide sufficient benefit to justify its development.
Therefore, the design proposed represents both the optimum planning, environmental and technical solutions in this instance. As such, we believe the development as proposed is in accordance with planning guidance as defined above.
