2 Fixed Network Connectivity - Carrier Study The Bower, Roundwood Avenue, Stockley Park, Uxbridge UB11 1AF STRUCTURE The Bower is a commercial office property under construction/refurbishment located at Stockley Park, Uxbridge. The building is over three floors and will afford approximately 1,8 sq ft (1,00 sqm) of Grade A office accommodation over open floor plates with suspended ceilings and raised floors throughout. The building is of typical steel frame construction with glazed facades to all elevations and a full height atrium, and sits within an environment of other commercial properties of similar sizes and heights with good separation between adjacent buildings. Location Plan BT Exchange locations Routes and distances are indicative only TOPOGRAPHY N The Bower Roundwood Avenue UB11 1AF A08 N PRIMARY EXCHANGE,00m APPROX SECONDARY EXCHANGE,00m APPROX BT Exchange Information Primary Exchange (LWWDRA) (,00m approx) UB7 7LN Secondary Exchange (,00m approx) HAYES NORTH (LWHAY) UB HU GLOSSARY OF TERMS SUMMARY TELECOMS CARRIERS BT SUMMARY The Bower is located approximately,00m from the BT West Drayton Exchange, which is situated to the south west of the building. West Drayton Exchange provides excellent services including ADSL, ADSL+, SDSL, 1CN WBC and FTTC services to some areas, plus the availability of LLU services from C&W, Sky and Talk Talk all over BT infrastructure. Based on the existing standard copper services, West Drayton Exchange offers broadband speeds of around 6Mbs at this time due to distance constraints. This exchange does not currently provide full FTTC services to this location, and provides no dates for such service deployment (Data via the BT website). Hayes North Exchange to the north east affords a similar range of services, including FTTC to some areas and could provide a level of diversity and resilience across BT business services should it be required. Telecommunications carriers with owned infrastructure located adjacent the park entrance are listed below for information. In addition to these, there are a number of alternative carriers that can provide service, albeit over a third party network such as BT. It must be noted that the presence of infrastructure within the search area does not constitute availability of service. British Telecom Tel: Vodafone Tel: Virgin Media Tel: Verizon Tel: Colt Telecommunications Tel: Zayo Tel: EU Networks Tel: The BT services available at West Drayton Exchange, and added resilience of a second exchange afford The Bower an excellent level of services to meet today's business needs, with the added advantage of good diversity and resilience opportunities. The physical presence of alternative carriers infrastructure to BT including that from Vodafone, Virgin Media, Verizon, Colt Telecommunications, Zayo and EU Networks affords the building with an excellent choice of carriers with minimal requirements for civil infrastructure in most cases due to the existing on-site infrastructure routing. The added benefit of the estates processes and procedures afford all carriers an excellent level of resilience and security. RATING BT OTHERS BT 1 Low (Copper only) Fair (Copper internal, fibre external) (Copper / Fibre internally) Excellent (Copper/Fibre internally) with diversity OTHERS 1 None (No alternative carriers adjacent to site) Fair (Single alternative carrier adjacent to site) (Multiple carriers adjacent to site) Excellent (Alternative carrier infrastructure on site) ADSL (Asymmetric Digital Subscriber Line) Asymmetric line speed, the speed from the internet to the user, and the user to the internet are different. Feed over copper cable, governed by distance from exchange to user. (co-exists with voice services) ADSL+ (Asymmetric Digital Subscriber Line+) Asymmetric line speed as above, but with faster connections both downstream and upstream over similar distance following roll-out of BT s 1CN Wholesale Broadband Connect (WBC). SDSL (Symmetric Digital Subscriber Line) Symmetric line speed, the speed between the user and the internet are the same in both directions but cannot co-exist with voice services over the same line. FTTC (Fibre to the Cabinet) Provides fibre to the cabinet, shortening copper cable length requirements to enhance speed FTTP (Fibre to the Premises) Provides fibre direct to the premises at a lower cost than that of standard lease line products LLU (Local Loop Unbundling) Is the process by which third party network operators are able to install equipment into BT exchanges in order to deliver their own services without having to utilise BT s network. BT Infinity (British Telecom ) Fibre to the cabinet/premises delivered services from enabled exchanges providing broadband speeds of up to 80Mbs download (subject to conditions) at a lower cost to that of traditional leased fibre services.

3 Mobile Voice / Data Appraisal - Coverage Predictions The Bower, Roundwood Avenue, Stockley Park, Uxbridge UB11 1AF STRUCTURE The Bower is a commercial office property under construction/refurbishment located at Stockley Park, Uxbridge. The building is over three floors and will afford approximately 1,8 sq ft (1,00 sqm) of Grade A office accommodation over open floor plates with suspended ceilings and raised floors throughout. The building is of typical steel frame construction with glazed facades to all elevations and a full height atrium, and sits within an environment of other commercial properties of similar sizes and heights with good separation between adjacent buildings.

Based on the location and serving cells, it is envisaged that a good/variable level of coverage will be present throughout the building for, G and G services, potentially with some limited isolated issues in internal rooms on the lower floor. In cases of coverage issues, each of the operators can provide solutions to enhance their service of which we can provide details and assist in their procurement and installation should they be required. Further to the coverage levels, the availability of service is dependant on capacity. This is the volume of data and simultaneous voice calls the macro cell can accommodate at any one time. Capacity issues result in network busy messages or dropped calls. The level of capacity can be addressed by the operators should the building be populated with a high number of users on a single network which will impact on both them and others using the same cell. EE operates under both the TMobile and Orange brands within the United Kingdom / Three operates a G/G network only G G Cell Site Information Macro site typically >10m above ground level Street level micro cells typically <10m above ground level All locations are approximate only Vodafone The Bower affords an excellent level of macro coverage from all operators for, G and G services. The closest serving cells are detailed in respect of, G and G services and can be seen vary in location and distance, providing general coverage to the building. Any high concentration of users within the units may impact on the capacity available especially if this is confined to any one single network operator. Based on this information it is considered to be a location that affords an excellent level of overall coverage across all operators at street level for, G and G services.

4 Fixed Telecoms Appraisal Summary The Bower, Roundwood Avenue, Stockley Park, Uxbridge UB11 1AF Fixed Telecoms Appraisal Summary In addition to the Fixed Network carrier study completed, a review by survey of the building was undertaken on the 15 th October 015 accordingly. The purpose of this survey was to clearly identify the presence of existing fixed telecommunications carrier s infrastructure in the building, adjacent or within the local environs. LOOKING SOUTH ALONG ROUNDWOOD AVENUE SITE AERIAL VIEW (Building extent highlighted in red) LOOKING NORTH ALONG ROUNDWOOD AVENUE Local Carriers Stockley Park Estate is a private estate that governs the access for any telecommunications carriers under strict wayleave agreements, utilising owned infrastructure. Ewave Consulting have prior knowledge of the process and procedures enforced Stockley Park Management Team and understand the requirements and existing carriers within the estate. By inspection it is clear that a number of carriers are present within the public highway adjacent to the A08 Stockley Road including BT, Vodafone, Virgin Media, Verizon, Colt Telecommunications, Zayo and EU Networks (See Photographs 1, and ). Of these, we understand that the majority of these have existing wayleave agreements in place to enter the site. The installation of any apparatus (cabling for example) is controlled by Stockley Park s approved supplier from the public highway boundary to the building perimeter via existing ducts which extend around the estate. Final civil requirements (if required) into the specific building are then provided by the carrier where works are required within the building owners domain. Should any further carrier s (not currently under wayleave agreement) wish to access site they can undertake this following formal request and wayleave agreement.

5 Fixed Telecoms Appraisal Summary The Bower, Roundwood Avenue, Stockley Park, Uxbridge UB11 1AF Building Presence The building is currently under construction and consists only of the main steel frame and ground floor slab. On inspection there are two main points of telecommunication intake by means of existing chambers within the building footprint. The first is located at the south east corner of the building and consists of 6No. 100mm (approx) ducts into an existing chamber. All internal cabling has been cut off, but carriers termination equipment in some cases remains (See Photograph ). The current content of the chamber consists of both copper and fibre services from BT, with additional fibre services from Vodafone. However, there is a large number of cables within the chamber which could not be clearly identified at the time of survey and may be owned and operated by others. It was concluded that due to the type of termination equipment identified, this would have been located on the wall in the area and has been removed and relocated in the chamber as a temporary measure. The duct intakes enter the chamber from the eastern elevation and are assumed to provide passage back to the main networks in Roundwood Avenue to suit via the on-site duct routes. The second point of intake is located in the north west corner of the building and consists of 6No. 100mm (approx) ducts into an existing chamber (See Photograph 5). The content of this chamber is limited to that of BT services both copper and fibre. The copper services extend to a major cable affording approximately pairs which has been cut off at the chamber. The route of the intake ducts was confirmed by the on site representative as being fed from an existing chamber in the car park area adjacent to Roundwood Avenue (See Photograph 6). However, on inspection this chamber was marked by an alternative carrier rather than BT, but could be part of the on site sharing regime and be utilised by multiple carriers at this time. As part of the construction these existing chambers will be retained and addition ducts installed to provide access from the external environs into the four corners of the building. In addition, a 50mm wide cable tray will be installed adjacent to the incoming ducts within the raised access floor void providing access to the cabling risers positioned within the four internal cores common to all floors. Based on the proposals within the main build access to all internal areas will be excellent and be able to offer good diversity by separation if required.

6 Fixed Telecoms Appraisal Summary The Bower, Roundwood Avenue, Stockley Park, Uxbridge UB11 1AF Service Availability The standard services afforded by BT over its existing copper networks provides a level of broadband services with speeds expected in the region of 6Mbs due to distance constraints. West Drayton Exchange does not currently provide full FTTC services to this location, and provides no dates for such service deployment (Data via the BT website). Hayes North Exchange to the north east affords a similar range of services, plus FTTC to some areas and could provide a level of diversity and resilience across BT business services should it be required. However, the current level of business tariff services available from BT will provide an excellent level of service at this time. Furthermore, there are a host of companies that can provide enhanced products over the existing infrastructure providing smaller businesses a more affordable level of service if so required. The presence of Vodafone already within the building and Virgin Media, Verizon, Colt Telecommunications, Zayo and EU Networks at the entrance to the park, coupled with the existing duct infrastructure affords an excellent level of carrier choice and service provision with minimal timescales envisaged to installation. In addition, the actual presence of alternative carriers identified within the building is one that could reduce service provision timescales further should they be required by any incoming tenant. Summary Based on the local carrier infrastructure, the availability of services from BT and Vodafone already in the building, the availability of alternative carriers and the process and procedures managed by Stockley Park, we consider the building has an excellent level of connectivity with the ability to provide services in very short timescales and with a high level of resilience and security.
