Mesh Radio Assurance Event
• Todays event was organised as a Mesh Assurance Event for the DCC & Industry, by the Telefonica's Smart Radio Team.
• The event was hosted by the Building Research Establishment in Watford –which has many real unoccupied homes that we were able to use for Building Penetration Loss & Mesh Connectivity testing.
• The event took place over 3 consecutive days - 20th, 21st, & 22nd September 2016.
• The team will demonstrated the ability of Mesh Radio to connect meters in hard to reach location using antennas and Mesh Radio, and that the Commshubs could form and reform a mesh network in repeatable way to adjacent properties.
• The demonstration took place over the live O2 Network, and used the production; C4 Connode servers, & Comm Hubs using 10i Firmware
• The event deemed to be a successful event by the DCC & Industry.

01 – Committed Coverage Recap
WAN Coverage Solution
• SMIP contractual coverage will be achieved using cellular, antennas and mesh technology; a) 95% current footprint, b) 2% Cellular using Antennas, c) 0.75% using Mesh, d) 1.50% planned coverage, e) 0.75% remaining out of scope.
• The original business case & contract was constructed based 90% cellular & 10% Antenna + Mesh CH mix – but this was a prediction, so we expect the actual numbers to vary…Currently the Mesh & Antenna risk envelope remains between 7% to 13%. The final numbers will depend upon the sensitivity values achieved by the production CH.
• We continue to review the latest end-game coverage plans to assess the shortfall risk in 2021. This will also helps us predict future reliance in alternative technology; such as antennas and/or mesh.

Current Status
• We delivered 80% B8 & BI milestone on the 1st Oct 2015
• Today Telefonica covers 95% of premises in the South & Central Regions – Source Telefonica street level measurements.
• Antennas will increase that coverage by 2%, taking premise coverage to 97.0%.
• Mesh then provides a further 0.75%, taking the coverage to the required 97.75%.
B13 – 97.75% was delivered on the 01.01.2017
• With the combination of; Coverage, Antennas & Mesh radio described above, Telefonica have now delivered required 97.75% B13 Milestone. The coverage database provided, contains recommendations at premise level, indicating where Mesh may be replaced with new sites in the future, using ‘low reliability of coverage’, in the reliability field in the coverage checker database…
BMAX – 99.25% will be delivered on the 01.01.2021
• The remaining 1.5% BMAX milestone will be reliant on planned coverage delivery.
The final 0.75% of premise will remain out of scope

• Outdoor-Indoor Propagation for domestic buildings
• 88 MHz, 217 MHz, 698 MHz, 2.4 GHz, 5.7 GHz
• Building methods and materials – energy efficiency
• Previous studies: measurements & methodology
• Whole house tests, with and without energy efficient
products
• Anechoic chamber tests of individual products

Whole Building
Measurements
• CW sources at 88, 217, 698, 2410 and 5760 MHz
– Median values found to be repeatable to < 1 dB
– Separate measurements made in each room (5,000 to 20,000 data points per room)

Conclusions
• Use of wireless increasing, especially with smart metering/smart home agenda
• Use of metal coated products increases the building penetration loss, particularly for new build
• BRE engaging with the construction industry, technology and solution providers about this issue
• Further work will explore:
– Better propagation models
– Technology solutions
– Better guidance

We have three Communication Hub Types – We refer to them a Stock Keeping Unit SKU types:
– SKU 1 Cellular only – high gain vertical antenna
– SKU 2 Cellular with an SMA connector for an external cellular antenna & mesh short range radio
– SKU 3 Cellular with two SMA connectors for external antennas for cellular & mesh short range radio
These units will help us manage hard to reach locations through Antennas and Mesh Short Range Radio whilst simplifying installation process, leading to higher install success rates…
