Editor's Notes
- Talking Points: Market Requirements: What are the Real World needs for the device What are some secondary use cases that can be supported without adding extra cost Temperature Sensors Presence Data Location Data Repeater? Customer Requirements: How are they specifically using the Data it Generates Locally or Remotely Shared or not Shared Is it a Point Solution or connected to a system Point Solutions are typically more expensive and are typically limited to small number of devices connected to each other all from the same mfg Devices that know they will be connected to a “hub or gateway” can be stripped down to be more affordable in cost and battery usage. Is it Retrofitable Technical Requirements: Interoperability HW Zigbee Profile HA 1.2 Switch Light Thermostat Zwave Door Sensor Motion Sensor Certifications Different Certs for Different Countries Wireless Certs Safety Certs Questions: Explain some different examples of devices you have created that had very specific requirements but had to keep interoperability.
- Talking Points: Seen or not be seen: Is the device meant to be hidden away and/or blend into its surroundings or is it something that should stick out? This has really changed as technology has progressed but some devices are just not yet meant to be a focal point. Nest is Light switches are not quite there yet Gateway device Wifi Allows the device to be placed in the open and requires Design to be aesthetically pleasing even if it is hidden away. Cellular Requires Device to be placed in a location with good Cell Coverage Stripped down Data reporting Ethernet Requires it to be located near an Ethernet switch or Cable Modem Typically, these are not in the prime lcoatio Battery, Mains Powered or Both Is it Meant for a DIY retrofit If Battery, What should the typical Life be? Should it be an off the shelf battery or does the design prevent that? Rechargeable? If Mains Powered, would a repeating functionality make sense to add in at no cost? UX: How does the End User Interact with a device that might just have an LED and button or now button at all like a light bulb What form factor is needed to make it retrofittable Plug Modules and all their types How do you get Diagnostics out of a device to do trouble shooting. Very important for the “Support” section of this talk Questions: 1. Typcially do devices of like types have similar User Interfaces or have you found interesting ways to expand the UX without Modifying the devices original design? (BTLE)
- Talking Points: Edge Tier: IOT systems includes ‘physical’ devices Building, Testing, Demonstrating all require a physical location. Challenging in a world where we work remotely more and more. The battle of languages: how embedded system are re-defining an industry Range of issues software people are not used to: hard power constraints, wireless connectivity Global systems must resolve: differences in power and wireless standards, export controls, production costs, logistics and customs. Platform Tier: Volumes of data. Simple hospitality IOT system recently evaluated to 1.5B transactions per quarter GE jet engine produces 1TB data/day Enterprise Tier: All our projects are brown field Making SOA efforts pay off: Presence of ESB to reduce cost of development, maintenance, business intelligence. Public Tier: Separate from Edge tier because not all IOT systems are open to the public Separating from Edge Tier to differentiate device-driven communications and user-driven communications Questions: What are your key take-aways from developing IOT systems?
- Talking points: CIA - the standard in terms of security Confidentiality: information only accessible to intended parties (identity) Integrity: information should arrive as it was sent (securing communications) Availability: information must be available to all those authorized. Key aspects of security that makes IOT different: Physical: Physical security involves preventing hackers from tempering with physical devices Making connected cars safe? telematics project Direction: IOT systems are not like typical client-server systems because servers can initiate communications with clients How do you make sure your system doesn’t initiate communication with a device that lost its integrity? Volume: and expected response times making securing systems difficult Detecting threat patterns in exabytes of incoming data Need in-memory streaming systems like the ones used to secure financial traffic such as Amex transactions flow. Trust: Probably one of the most challenging sides of securing IOT Entertainment company needed to allow customers (hundreds of millions of them) to book shared experiences Large scale trusting model: making your garage door trust your car... Managing device ownership transfers Question to groups: What are your experiences with this concepts?
- Install equipment Routers, Hubs, Repeaters End-point devices Provision equipment Get all devices within an installation talking to one another Deploy application(s) Enable installers with utilities to complete installation and provision devices Enable users and customers with applications appropriate for their needs Create accounts Users of system with appropriate roles, privileges and access Customers with privileges and access to deliver end customer experience Claim equipment Associate end-point devices to user accounts Setup meta-data
- Traditional Support end-point devices Additional Support connectivity infrastructure equipment Support cloud infrastructure Support application infrastructure and applications Monitor device information – performance and diagnostic information Latent product and connectivity issues Connected devices add a tremendous effort on the Support front.
