3. Multi-Interface Market
Why do devices have multiple interfaces?
Ubiquitous access!
21-08-doc-number

4. Multi-Radio Market
The market is seeing the introduction of many dual-radio devices.
For Example:
GSM/WiFi and CMDA2000/WiFi phones
EV-DO/WiMax on Cardbus
EV-DO/WiMax on USB
WiMax/WiFi on PCI-Express
21-08-doc-number

5. Dual-Radio Market Also consider:
The typical laptop with integrated wired and wireless LAN interfaces
New Mobile Internet Devices (MID) and Ultra-Mobile PC (UMPC)
These are just examples. Many other variations are on the horizon.

6. Service Provider Desires
Provide the user with ubiquitous and “seamless” access
Note a movement among some service providers to “share” access networks, especially where the underlying technology (e.g. WiMax, WiFi) tends to encourage this
Note also a movement from consumers to have ubiquitous access from a single service provider (e.g. many WiFi hotspot providers and ISP aggregators)
21-08-doc-number

7. Service Provider Desires
An optimal end-user experience where the user is not bothered by:
Having to discover available networks
Selecting the best network (based on cost, performance, or other criteria)
Setting the criteria for the “best network”
Concern for battery life on the platform in use
Enabling and disabling interfaces
21-08-doc-number

8. Service Provider Desires
A method to reduce the service provider’s cost of providing “ubiquitous” access to the consumer
Primarily to use “paid-for” or free (typically owned or “open-access”) facilities when available
instead of “for-pay” (leased or contracted) facilities
21-08-doc-number

9. Existing Solutions End-User manually manages connections
Manual configuration frustrates the end-user because:
Time required to figure out which connection to use and enable it
Frustrated by short battery life
Knowledge required of the OS and installed interfaces to enable/disable interfaces
21-08-doc-number

10. Existing Solutions
Client-based (typically laptops) connection management software
Searches for available networks
Based on pre-programmed criteria the software chooses the “most desirable” network (not necessarily “best-available”)
May or may not disable other interfaces (for the purpose of battery-life, network use cost-reduction, etc.)
21-08-doc-number

11. Gaps
Some dual-mode products that are available on the market today require more power than is available
For example: USB can provide up to 0.5 amps, but current dual-mode USB WWAN devices require >0.5 amps to have both radios enabled.
21-08-doc-number

12. Gaps
Connection manager software is unable to discover all available networks without powering up each interface in-turn.
Possibly requiring the user to wait longer than desired
Possibly using more batter power than is desired, especially for small devices (typical dual-mode mobile phone battery is rated mAH)
21-08-doc-number

13. Gaps
Service Provider is unable to dynamically interact with the client platform:
To inform the user platform that another interface is more desirable than the currently active one
To inform the user platform that data is available/waiting for delivery to an inactive interface
To provide an alternate path for delivery of data destined for an inactive radio on the platform via a currently active radio (this would save time in the delivery process and reduce power-use)
