Introduction - Purpose of Mesh Desktop demonstrationObjectives:

• Show the principles of the Telefonica Smart Meter Wide Area Network Solution.

• Show that the Connode Mesh is a proven and robust Smart Metering solution.

• Provide a demonstration of the Connode Mesh network. We will demonstrate that connectivity using a desktop environment.

• Show that the Communication Hub Install & Leave processs will leave you with the best chance of a connection.

• Show that the Coverage Checker Database will tell you which Ccommunication Hub WAN variant to install.

We have three Communication Hub Types – We refer to them a Stock Keeping Unit SKU types or Communication Hub “Variants”:

– 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.

The Smart Meter Wide Area Network Partnership Solution

The Telefonica Smart Meter Wide Area Network uses both O2 market leading 2G + 3G network and reinforces this with Connode Mesh Network Technology to connect those hard to reach locations.

• World class references from Connode & Toshiba

• RF Mesh – cost effective SW licence from Connode

• IPv6 network – all the way to the Comms Hub

• Dynamic and seamless transition 2G/3G <-> Mesh

• Close collaborative partnership between Telefonica, Toshiba & Connode

Who are Connode & why is their technology so important?

• Who are Connode? Connode are a market leading provider of wireless solutions in Europe for Smart Metering, with many years of experience and some 650.000 nodes in service with over 30 utilities. Helsinki reference site..

• Why choose Connode? Connode’s implementation of this technology provides a self-configuring, self-annealing and self-healing capabilities makes it an ideal choice for a mesh wide area network. IPv6 to the Hub… Its adaptive nature makes it ideal for coverage hard to reach locations.

• Cost effective solution? Connode’s solution has been proven to reduced both cost and downtime for the utilities.

• What is 6LoWPAN ? IPv6 over Low-Power Wireless Personal Area Networks” –is a networking technology that allows IPv6 packets to be carried efficiently within small link layer frames, such as those defined by IEEE 802.15.4.

Examples of mesh deployment scenariosMesh will be required at less than 1% (195,000) of all premises. There are three mesh deployment types:• Boundary Mesh(4%) – installed to provide a

cellular gateway for a mesh area. Shown as the red locations adjacent to the white no coverage areas. Will include antennas.

• Planned Mesh(0.5%) - Where the property doesn’t receive adequate cellular coverage. Shown as the yellow location in the white no coverage area. Installations are not due to start until early 2017 to allow adequate testing of the Mesh wide area solution.

• Ad-hoc Mesh(0.5%) - “Install and leave” where a cellular + mesh hub has been installed as cellular only can’t connect. Shown as the yellow locations in the blue coverage area. Additional adjacent premise are automatically identified for Cellular + Mesh hub installation prior to any installation.

Summary• The Coverage Checker database (CCDB) available via the DCC Self Service

Interface (SSI) or via DCC User Interface Service (DUIS) provides details of the correct Communication Hub WAN Variant to install at a premises.

• At times the SKU2 mesh capable Comms Hub will be “proactively” prescribed.

• Following the Comms Hub Installation and Maintenance Support Materials (CHIMSM) the SKU2 mesh capable Comms hub will be “reactively” installed - where the SKU1 cellular only Comms Hub does not connect.

• The Connode Mesh solution is tried, tested, and approved by Telefonica

• The Mesh Street showcase planned for June 2016 at the Buildings Research Establishment will provide the opportunity for an Industry assurance event which demonstrates Telefonica’s successful implementation of an already proven Smart Metering Mesh Technology
