Handset per PC sales ratio grows to five per one

Yearly Sales of all PCs grow moderately to approx. 170 Mio in 2009
Proportion of mobile PCs rises from a quarter today to a third in 2009
By 2009 the vast majority of all sold notebooks will be WLAN enabled
In parallel the yearly handset sales will rise from 450 Mio. to 850 Mio.

Navigation Difficult Keypad too small Security & privacy Slow Access Unfamiliar with technology Poor Content

Mobile, with data use Mobile, but no data use

user can‘t predict fitness for mobile use
navigation structures adaption: size, I/O
non-standard embedded scripting
content too extensive for user context
unsupported browser specific markup
exceeding displayable page size limits
missing/wrong data in device profiles
transfer bar knowing if displayable
not using caching options
lack of using wTCP, wHTTP profiles
user/password login schemes
concern of unwanted push

Overcoming key inhibitors of mobile internet use will expand the benefit of the Internet as a whole

Promote using device independence standards

Content frequently created without device independence anticipation Significant portion of current and mid-term future installed base can not be

addressed in an either “Browser-only” or “Server-Only” approach

Identify and remove limits with applying existing standards

Quality of device profiles (lack of defined versioning process, incomplete

parameters, diverging vocabularies)

Growth of standards complexity exceeds content/service creators adoption rate

Remove limits within standards creation processes

Areas of remit between standards bodies leave too much room for “dialects” Availability of best common practices / references key unmet requirement

Build trust for the mobile user experience of the Internet

No generic way to discover end to end mobility compliance for consumers

e.g. search: “try & error, error, error & goodbye”

No generic, industry wide brand established that such trust could be bound to

T-Mobile activity: Devices, Profiles, Process, Tools Building Trust

Targeting mobile audience by editorial processes & by using device profiles

Use authors trained and experienced in creating “to the point” content Classification of device capabilities Definition of a limited set of device classes focussing around device proliferation Map devices to these classes using (heavily quality assured) UA profiles Support creation of standards to describe selection (e.g. per delivery class)

Influence requirements and compliance testing within device offerings

UAprof, wHTTP, wTCP, WAP 2.0

Orchestrated work in standardization bodies to harmonize efforts

3GPP, ETSI, GSMA, IETF, OMA, W3C, etc.

Create interoperability frameworks and a best practices
Engage in industry consortiums that represent mobile customers interests,

create mobility brands and grow consumers trust into mobile Internet use

ToDo: Technology, process and non-technical issues need a concerted improvement

Improve awareness on „the mobile case“

Socialize demographics, growth, installed base of the mobile community

Increase realibility of standards creation results and ease uptake

Define vocabulary maintenance processes for device attributes Extend maintenance process for UA profiles Support clarification of areas of remit between OMA and W3C

Expand usage of standards

Create best practice guidelines / styleguides / examples Support definition of compliance analytics Support definition of testing tools and procedures

Create predictability of user experience for mobile use

Define technology brand that reflects the promise to support mobile use („mobile OK“ ) Identify some means to make the brand available for all Support creation of non-technology related brand quickly Caveat: Limiting change in the installed base of standards compliant sites & services
