Re: [ g] TG4g Call for Preliminary Proposals, 2 February, 2009
Abstract: Looking at the speed of SUN devices over the past 20 years, we can see an increase by a ratio of 10 every 12 years. More and more data is being transferred through the SUN. For the next 5 to 10 years, this increase in speed will require the use of more modern and efficient PHY technology, such as OFDM.
Purpose: Proposal to add OFDM technology in addition to SSFH as part of one of the protocols defined in g

6. High ratio endpoints/network device
27 February, 2009
High ratio endpoints/network device
Limited available locations
High operational costs
Tight regulations
The network devices have to cover the traffic for a high number of endpoints (high 100’s to 1000’s per network device)
Emmanuel Monnerie, Landis+Gyr

7. 27 February, 2009
Mass outage reporting
Millions of endpoints can report outage and restoration data at the same time.
This represents a peak data throughput well above the average traffic
A low latency outage reporting (< 5 minutes) is required from each affected meter

8. Utility network access point
27 February, 2009
Utility network access point
Interface between the utility network and the utility host application.
Handles the traffic for a large geographical area (tens of thousands of residences each)
Relatively high operational costs
Very limited choice of locations
Could be located several miles away from the main network
The network traffic bottleneck is here
The capacity of this device is usually sized for extreme scenarios
Emmanuel Monnerie, Landis+Gyr

9. 27 February, 2009
Long term planning
A typical utility network is designed to operate for years
The requirements for new applications will grow, which will require more bandwidth.
There must be availability for growth in the modulation scheme
Retrofit of older devices is the most expensive part of a Utility Network deployment.
Backwards compatibility is a must
A hardware with room for future expansion is desired
Requirement for remote firmware download and remote diagnostics and configuration
Automatic configuration and network registration
Software Defined Radio?

10. Spectrum usage issue Limited available spectrum
27 February, 2009
Spectrum usage issue
Limited available spectrum
Typical frequency range for utility networks in the US: MHz (license free ISM band, part ).
Narrow license free spectrum in Europe
Heavily used spectrum (consumer devices, industrial applications, … and smart meters)
RF collision issue: A inefficient use of the spectrum decreases size of the unused space, which will increase the probability of RF collisions
Emmanuel Monnerie, Landis+Gyr

11. A better use of the spectrum
27 February, 2009
A better use of the spectrum
Frequency hopping should allow increased traffic robustness
A higher number of channels is better to avoid not only jammers but also collisions between devices from within the same network
A modulation scheme with high spectrum efficiency should be included: OFDM
Emmanuel Monnerie, Landis+Gyr

12. Benefits of OFDM for a SUN
27 February, 2009
Benefits of OFDM for a SUN
Improved spectral efficiency compared to single carrier modulation
Increased robustness for wireless fixed networks:
Robustness against time synchronization error
Relatively simple channel equalization
Robustness in multipath environment (urban, suburban)
Scalability
Can be deployed today at lower speed rates and upgraded later to accommodate new needs for bandwidth.
Emmanuel Monnerie, Landis+Gyr

13. 27 February, 2009
Conclusion/Proposal
The requirements for a SUN PHY should consider signaling speeds above 100kbps-200kps
When looking 10/20 years ahead, the need might be around 1Mbps
The devices might need to handle different PHY to ensure backwards compatibility
Flexibility for bandwidth growth must be considered
OFDM combined with frequency hopping provides both proven operation in the ISM bands and a path for bandwidth growth into the future
We recommend that this group considers OFDM as a highly suitable option for the enhanced g specification
