Jon CananProgram ManagerMicrosoft Corporation

Provides Location Based Services to GPS navigation devices over an FM radio subcarrier broadcast

Initially includes traffic, gas prices, weather, and movie times

All data is geo-encoded Enables content filtering based on current GPS locationRouting engine can route around traffic and take the customer to the cheapest gas, movie theater of their choice, etc.

Delivered via the Microsoft DirectBand® networkGarmin® was first OEM, products available now

Two models: nüvi® 680 & StreetPilot® c580MSN Direct receiver built into car charger

A broadcast data delivery platform, network & serviceMicrosoft is the wireless operator

Long term and exclusive access to bandwidthMicrosoft provides

Receiver HW & SW technology, all decoding of OTA streamBackend content collection, packaging, scheduling, deliveryBilling, device activation, customer supportNetwork operations & monitoring

Multi-network strategyDifferent networks for different devices/marketsFirst network using subcarrier on FM radio towers (but not RDS)Second network based on HD Radio under development Investigating DVB-H, DMB, or MediaFLO

Terminology:

Low cost bandwidthOne-to-many requires much less bandwidth than point-to-pointFew players competing for it, little demand for the bandwidthCell operators spend billions for spectrum, billions more to deployA single big FM tower can cover an entire metro area

Consumers benefit via significantly lower feesMSN Direct Navigation Service = $49/yr or $129 one-time paymentVerizon VZ Navigator Service = $119/yr + airtime or data plan

And that is just for basic navigation – doesn’t even include traffic

Most data can be delivered via broadcastTraffic, gas prices, movie times, weather, sports, stocks, etc.Client-side filtering allows UX to be personalized to each user

Receivers can be very power efficient – never transmit

Coverage, coverage, coverageMSN Direct covers 77% of US Population

Power consumptionDirectBand receiver about 10x more power efficient

RangeOne FM tower covers entire region – allows receiver to stay locked on while drivingWiFi would require constant tower switching while driving

Deployment/operations costMuch cheaper to deploy, maintain, and operate equipment in a few FM radio stations than a large number of WiFi access points

Analog DirectBand uses the 67 kHz FM sub-carrier Bandwidth is 11.5 kbps per city (analog FM, HD will be more)Aggregate bandwidth across all cities is 1.43 MbpsDelivers 100 MB per day, per city Bandwidth dedicated entirely to data – focus on local contentGood in-building penetration (compare to sat radio)

Content Delivery SchedulingDynamic priorities and service level by data typePrevents starvation, meets varying application needs for QoS

Network fault tolerance and monitoringMultiple towers, multiple WAN providers, redundant equipmentField monitors trigger automatic failover when needed

Error correctionViterbi, Reed Solomon, Low Density Parity Codes, Packet Interleaving (for time diversity)

EncryptionExTEA (Extended Tiny Encryption Algorithm)Personal content signed with a private keyBroadcast content signed with a service key which changes periodically and is delivered to active users in personal messages

Microsoft Streets & Trips 2008 with Connected ServicesAdditional partners and services coming soonMSN Direct HD

HD Radio is a digital upgrade for terrestrial AM & FM radioBenefits: Use existing HD receiver in vehicle, more bandwidthAnnounced collaboration with Clear Channel at CES 2007

Clear Channel provides network, MSN Direct builds the technology and operates the service

Won’t replace MSN Direct – both networks will operate in parallelContent and Bandwidth

Hybrid Mode: 12 kbps dedicated bandwidth Content would be similar to existing MSN Direct Service

Extended Hybrid: 36 kbps dedicated bandwidth3x more bandwidth than current analog MSN Direct, will enable more, deeper content
