The IoT Hunger Games 2015

Published on

How new Low Power Wireless Area Networks (LPWAN's) are aggressively challenging the Internet of Things status quo and how industry can exploit this opportunity. Specifically, the ability to query IoT endpoints in real time, improve network capacity and data rates, and the ability to deploy a filesystem in order to create a "Hadoop"-like real-time query capability at the edge of the network is explored.

The IoT Hunger Games 2015

  1. 1. The iot Hunger games 2015 ONE TECHNOLOGY IS DRIVING A NEW WAVE OF INNOVATION FOR THE INTERNET OF THINGS …
  2. 2. WHO WE ARE We began driving innovations in the internet of things over 10 years ago at our last company, Savi Technology and believe that the best way to connect networks with many battery-powered sensors is not through WiFi, Bluetooth, or cellular, but via something better. We invented a better way of connecting things using very low power and over long distances, a technology called DASH7. Our company also builds tools, API’s, and software to make DASH7 more accessible to developers. We recently began receiving inquiries about a new class of IoT modulation technologies called Low Power Wide Area Networks. We think LPWAN’s are exciting and this presentation tells you why.
  3. 3. LOW POWER STATUS QUO 30 feet 3 miles300 feet Short Range / “WPAN” Medium Range
  4. 4. NEW CHALLENGERS Short Range / Local Area Medium Range up to 30 Miles Long Range / “LPWAN” 30 feet 3 miles300 feet
  5. 5. RANGE IS MASSIVELY BETTER up to 30 Miles Long Range / “LPWAN” 30 feet 3 miles300 feet Short Range / Local Area Medium Range
  6. 6. 30 feet 300 feet 5 Kilometers Long Range / “LPWAN” up to 30 Miles FOR THE SAME PRICE Short Range / Local Area Medium Range Low Power Wide Area Networks • Very long range • Multi-year AA battery life • Low cost: sub-$10 per node
  7. 7. THE FUTURE OF THE IOT 10 meters 5 Kilometers100 meters Short Range / Local Area Medium Range Long Range / “LPWAN” up to 50 Kilometers We believe most wireless sensor networks will be LPWAN- based, as LPWAN’s offer comparable pricing and power consumption to legacy WPAN/WLAN options, but with: • Significantly improved range and signal coverage • Better monetization opportunities for customers
  8. 8. KEYS TO LPWAN LONG RANGE + +Sub-1GHz Radio Bands Really Low Bit Rates Frequency Spreading Longer wavelengths allow vastly longer range and lower power consumption Common bands include 915, 868, 433, and 169 MHz. Technology being deployed in most LPWAN modulation schemes use some form of spreading to combat interference Low data rates of just a few hundred bps increase range, but as a result the packets get very “long”, which leads to new challenges.
  9. 9. + +Sub-1GHz Radio Bands Really Low Bit Rates Frequency Spreading Longer wavelengths allow vastly longer range and lower power consumption Common bands include 915, 868, 433, and 169 MHz. Technology being deployed in most LPWAN modulation schemes use some form of spreading to combat interference Low data rates of just a few hundred bps increase range, but as a result the packets get very long. This leads to new challenges. KEYS TO LPWAN LONG RANGE These technologies for achieving long range are old and well-established. Advances in semiconductor technology over the last 40 years are what enable low-cost and low-power. So barriers-to-entry are also low …

  14. 14. BUT DEVELOPERS HESITATE 1. Choosing wisely among multiple LPWAN suppliers, including some which may disappear in a year or two, 
 is difficult. 2. There is no LPWAN PHY standard. 
 In fact, the three prominent PHYs are radically different. 3. No standardized networking stack. 4. Market is dominated by high cost, single-vendor silicon. 5. Scalability of some LPWAN technologies

  20. 20. THIS IDEA MAKES SENSE 1. Avoids fragmentation. Too many competing stacks over different PHY’s = slow growth. 2. Proprietary stacks are not portable across PHY’s. For example, SigFox’s stack only works with SigFox’s own unique PHY and operating configuration. Similarly, stacks like LoRaWan are limited to a single provider of silicon. 3. “Roll-your-own” stack inhibits developers and customers. A common stack gives developers and customers the option to choose among PHY technologies and focus on the application layer, while lowering maintenance and support costs. 4. Interoperability. Standardizing provides key elements of interoperability, creating new product and application opportunities like multi-PHY gateways and endpoints, similar to WiFi. 5. Performance improvements. Roll-your-own stacks will be slower to respond to marketplace innovations as well as among PHY layer suppliers. A common stack makes the trajectory of LPWAN’s more assured!
  21. 21. Requirement Provide Robust 
 Networking Features P2P, broadcast, multicast, and IP addressing. Ad-hoc networking. Rapid device discovery. Deployable across global ISM bands, not just USA or EU. Improves network capacity. Real-time locating system support. Real-Time Data Collection Some IoT technologies achieve long battery life using huge time intervals between messages. Customers want their data when they want it and want to be able to “Google” their network for a diverse range of criteria and data types. Preserve or Improve 
 Long Range Messaging Sounds obvious, but not all stacks can support the long range or cellular-like design of LPWAN’s with a fully two-way system that does not compromise battery life or network capacity. Provide Maximum Practical Security & Privacy This is a big topic, but a LPWAN stack must at a minimum support a) MAC-layer address encryption, b) AES, RSA, or ECC data encryption standards, and c) devices must remain silent until awoken by an authorized device. Preserve or Improve 
 Battery Life It’s not enough to support long-range messaging. A stack must have a neutral or positive effect on battery life without compromising latency or range. WHAT THIS STACK HAS TO DO (At a minimum)
