Understanding Silver Spring Networks Access Points 1 1 About Access Points About Access Points Overview The Silver Spring Access Point (AP) provides the central link between endpoint devices and network control and monitoring. It is the connectivity between intelligent endpoints and the utility’s back office. Its flexible communication features extend the reach and coverage of the network to thousands of customer premises, through scalability that lowers ownership costs.
Understanding Silver Spring Networks Access Points 1 About Access Points Division Multiple Access, Long Term Evolution, High Speed Packet Access, single carrier Radio Transmission Technology) Wide Area Network (WAN) interface, or with a 10/100 Ethernet interface. The Access Point provides a method for implementing the last mile utility information and control network.
Understanding Silver Spring Networks Access Points 1 About Access Points Figure 2 shows an Ethernet AP. Figure 2. Silver Spring Networks Access Point (AP) Cellular antenna Power connector NAN antenna Battery Backups APs can be configured with battery backups. In the event of a power failure, the battery backup can provide continuous operation for at least eight hours. Silver Spring Networks suggests as a best practice, a battery backup within the Access Point.
Understanding Silver Spring Networks Access Points 1 About Access Points The design float life of Silver Spring‐IBP products is up to eight (8) to ten (10) years at room temperature (25°C/77°F) and under proper charging conditions. This design life has been confirmed by the use of accelerated testing methods that are widely accepted by both manufacturers and users of sealed‐lead batteries. High temperatures are used to accelerate the aging process of the battery under test.
Understanding Silver Spring Networks Access Points 1 About Access Points Cellular Modem Currently, the modem is a Sierra Wireless AirLink, RavenX, RavenXT, or RavenXE depending on AP model and country location. Addressing Schemes Silver Spring’s addressing scheme is based on the Internet Protocol (IP) suite. Each network device has one or more IPv6 addresses within the LAN. The Access Point will typically have an IPv4 address assigned to the WAN side.

The following standards were applied: • EMC: EN 55022 (2010), EN 55024(2010), EN 61000‐3‐2 (2006) EN 61000‐3‐3 (2008), ETSI EN 301 489‐3 v1.4.1 • Safety: EN 60950‐1:2006, EN 60950‐22:2006, BS‐EN 62311 (2008) • Radio: ETSI EN 300 220‐1 v2.3.1 (2010‐02), ETSI EN 300 220‐2 v2.3.
Understanding Silver Spring Networks Access Points 1 About Access Points this message to the operator. Spare pre‐configured Access Points are kept on hand, and are scheduled for network insertion within the utilities work order management system. Within NEM, GridScape, or HCM, the failed Access Point is flagged for RMA, and the device is replaced. Surge Protection APs comply with up to 20kV for combination wave and up to 6kV for ring waves (reflects the current Ethernet AP and projected assembly.
Understanding Silver Spring Networks Access Points 1 About Access Points The design rule for Access Point to RF devices is 1 to 5,000. At this ratio, the maximum data throughput required from a WAN solution is 40kbps per Access Point. Based on real‐world data on a network of this size, the average wireless speed is measured at 2.6Mbps downstream and 700Kbps upstream, which is well in excess of requirements.
Understanding Silver Spring Networks Access Points 1 About Access Points 15 Kbps or 15%, leaving 85% for other smart grid solutions such as DA or DR (disaster recovery). Figure 4. Average bandwidth consumed by AMI traffic It is worth noting that there are a number of factors that impact each RF Mesh link between any two nodes including but not limited to: scheduled jobs (such as meter reads), path selection from an RF device to an Access Point, failures or outages, etc.

Understanding Silver Spring Networks Access Points 1 About Access Points Responding to a WAN Failure An AP might not be reachable because the device cannot dial out on the WAN. The device continues to try dialing out until it is either able to connect, or it has dialed 308 times. If it can connect, the device notifies the event management program that it has successfully recovered. If it cannot, then the modem resets itself.
Understanding Silver Spring Networks Access Points 1 About Access Points Address Management For the LAN, a DDNS (Dynamic DNS) system is used. Each device has one or more IPv6 addressed assigned to it, based on its location in the network and route out of the LAN. These addresses are then stored at the head end and used for all communications with the devices (ping, trace, reads, etc.), giving the customer a true, native end‐to‐end IP network.
Understanding Silver Spring Networks Access Points 1 About Access Points Configuration To facilitate the configuration and remove the chance for human error (for example, typos) a simple shell script is generated and run from a UNIX‐based laptop which has a Silver Spring Field Service Unit attached to the USB port. All Silver Spring APs are configured during the manufacturing process to ensure that the proper profile (Network ID, etc.) is included.
