Along with the Sure telecoms equipment, there will also be Tetra Tx/Rx antennas for DHA and other 3rd party equipment that will be reinstalled from the old structure to the new proposed structure. *MIMO, Multiple In Multiple Out, this is a protocol required for higher speeds and high capacity 4G/LTE The Application Site The location for the proposed works is to the rear of ESJCR, Dukes Avenue

Alternative options would include building multiple sites in surrounding areas to offer similar levels of coverage, however, this would have a larger visual impact due to the need for multiple smaller towers to offer similar coverage to one structure. The tower at ESJCR has been in place for over 25 years so it has been part of the Douglas skyline for a considerable amount of time, the proposed plans would be to replace this with the same type of structure, just with 10-meter height reduction, this with the amount of time the structure has been in place will mitigate the visual impact of replacing the current structure. Visual Impact We believe that the visual impact of the proposed structure will be minimal, due to the structure type, having opted for a square lattice we believe that the structure will be less visually intrusive than other structure options, such as a monopole, due to the fact that it will not be a solid structure, but rather one that you can essentially look through, helping it blend in with the surroundings. The structure itself is a galvanised tower, this helps with mitigating visual impact further due to the structure blending better with the sky behind as you look up at it from surrounding areas. Along with this, as stated above, we are proposing the replacement of a tower that has been on the Douglas skyline for 25+ years with a new structure that is the same type, a square lattice but with an overall height that is 10-meters shorter than the current structure.

Number of Cabs 1 Ericsson 6150 Cabinet Height 2500mm Cabinet Width 800mm Cabinet Depth 700mm Cabinet Colour Neutral (options to paint to fit surroundings if deemed appropriate) Antennas 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 proposed structure will enable the surrounding areas to have access to the next generation of mobile technologies available, 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, The surrounding area will benefit from greater network capacity and service due to these improvements to the Sure mobile site.

Page 25 under Communications Commission Aims & Objectives Section: Objective: Social inclusion – to enhance access to services for the whole population: b. “We will enforce universal service obligations by telecoms operators with significant market power. They must provide telephone services throughout the Island,” 2. Isle of Man Government Statutory Boards< Offices & Agencies Plans 2005-2008. Volume 3 a. Page 20, under Communications Commission Aims & Objectives Section. Objective; The built environment - to reduce the visual impact of telecommunications and radio infrastructure on the island’s landscape. b. “We will encourage increased mast sharing by broadcasters, under the Radio Masts Regulation Act Limitations”. 3. The Town and Country Planning Act 1999. a. Page 101: “A balance must be struck between the need for new, evolving 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.” 4. 4) Isle of Man Government Digital Strategy and Digital Inclusion Strategy

It is something that has become so deeply embedded in daily life that it is hard to function when access to it is lost.” 6. 2.3 “In line with providing more digital services, Government needs to ensure that residents of the Island are equipped with the access, skills, motivation and trust to go online, to help those who want to be digitally capable to make the most of the internet.” Sure IOM Ltd believes the proposed installation complies with the Island’s policies and strategies above. Summary 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 proposed work to the site will enable Sure to provide improved, reliable coverage to residents and businesses in the surrounding areas, giving them access to the next generation of telecommunication services. 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.
