What is MMS? • Enhanced SMS…limited size messages are sent over the control (not the signaling) channels of a GSM’s network. GSM is circuit switched, whereas 3 G is an all-IP network. • Non-real-time, multi-media message service – – – • Uses IP data path & IP protocols (not SS 7) – • Text; Speech (AMR coding) Audio (MP 3, synthetic MIDI) Image, graphics (JPEG, GIF, PNG) Video (MPEG 4, H. 263) Will evolve with multimedia technologies WAP, HTTP, SMTP, etc. Adapts to terminal capabilities – – – media format conversions (JPEG to GIF) media type conversions (fax to image) SMS (2 G) terminal inter-working • MMs can be forwarded (w/o downloading) and may have validity period • Addressing by phone number (E. 164) or email address (RFC 822) • Extended reporting – submission, storage, delivery, reading, deletion • Supports an MMBox, i. e. a mail box • Optional support of media streaming (RTP/RTSP)
How Apps Run On Mobile Devices Three Paths: Native OS • Palm • Symbian • Windows CE • Linux Virtual Machine • Flash / J 2 ME • BREW • App. Forge • Syclo Agentry Markup Language VM Application ML Application VM (App) Browser (App) Device OS Processor
Mobile Languages • J 2 ME (JAVA) – • BREW – • Worldwide, SMS (Short Messaging Service) is the most popular data service for mobile phones, e. g. a broad range of SMS-based sports, information, and entertainment titles, using both one- and two-way messaging, each of which generates vast numbers of messages. Many SMS applications also send out real-time web-based reports for usage and billing tracking. MMS – • XHTML is the reformulation of HTML as an application of XML. SMS – • CHTML, or compact HTML, is a subset of HTML used for small information devices, such as smart phones and PDAs. CHTML is essentially a pared-down version of regular HTML over the Internet. Because small devices such as cellular phones have hardware restrictions such as small memory, low power CPUs, limited or no storage capabilities, small mono-color display screens, single-character fonts, and restricted input methods (the absence of a keyboard or a mouse), there is a need for this simpler form of HTML. XHTML – • XML is markup language for documents containing structured information. Structured information contains both content (words, pictures, etc. ) and some indication of what role that content plays (for example, content in a section heading has a different meaning from content in a footnote, which means something different than content in a figure caption or content in a database table). Almost all documents have some structure. A markup language is a mechanism to identify structures in a document. The XML specification defines a standard way to add markup to documents. CHTML – • QUALCOMM’s BREW (Binary Runtime Environment for Wireless) platform is a thin application execution environment that provides an open, standard platform for wireless devices. The complete BREW solution is controlled and managed by carriers, enabling them to easily get applications from developers to market and coordinate the billing and payment process. Carrier’s BREW-based services will enable consumers to customize their handsets by downloading applications over the air from a carrier’s application download server. XML – • J 2 ME is a highly optimized Java runtime environment. J 2 ME is used in many small consumer products, including smart cards, pagers, and wireless devices. The Multimedia Messaging Service (MMS) is, as its name suggests, the ability to send and receive messages comprising a combination of SMS with rich media including text, sounds, images, and video, but only to MMS capable handsets (e. g. GSM). WAP – WAP (Wireless Application Protocol) is a widely used set of protocols that standardize the manner in which wireless devices, such as cell phones and some PDAs, are able to access parts of the Internet, such as e-mail and the Web.
Wireless OS Contenders • Symbian – PDAs and smart phones • Palm. OS & Be. OS – Kyocera, Samsung, etc • Microsoft – Pocket. PC – Stinger • J 2 ME – RIM, Motorola, etc • BREW – Qualcomm chipset phones

Design Tips • • • Choose content carefully … only that which is essential. Customize the content specifically for the target user, concise and elegantly organized. Avoid clutter … plan for space economy. Wild colors and patterns splashed across the small screen is frustrating. Avoid graphics that reduce readability, fit them to one screen. Less use of graphics to reduce download time and local memory footprint. • Minimize page length, and maintain a balance between page depth (level of nested pages) and the length of individual pages. • Avoid scrolling …unless its and e-book, consider quick drill down navigation and hypertext link. • Organize information effectively, and test your application using PDA/phone-vendor supplied emulators (e. g. http: //www. palm. com/devzone/pose/seed. html) and then test them with an actual handheld device. • Use supported character sets, most handhelds use the full set of Latin 1 characters. International characters are not yet available as internal fonts on some devices. • Size does matter…Low end Palms are 160 x 160 pixels, the Pocket PC has a screen resolution of 240 x 320 pixels, some CLIÉ models offer 320 x 480, phones are smaller, but all screen resolutions are improving in typically 1. 5 -year device-ownership cycles • Scaling reduces the quality of many images, so you generally should avoid using images wider than the device's viewing area. Use "large" images sparingly and only when appropriate, as they not only consume screen real estate, they also consume synchronization bandwidth. • Choose contrasting colors…crisp edges. Images that are anti-aliased rarely convert well. • Designing graphics for small, bitmapped screens is something of an art…!

LBS Concept • Concept: – Find the position of mobile devices while using them for location-based data display and communication • Advantages: – People introduced to local products and services • emergencies, national security, fleet management, dating, logistics… – People can navigate to locations – People can compare nearby things, services, attractions – Suppliers can analyze traffic, qualify prospects and pre-sell – Local objects, services, products and events can be animated to communicate value – They can also co-relate, e. g. 3 -fishing buddies’ PDA’s and a boat-rental location are nearby
Example LBS • • 911 locator – Government mandate – Find someone within 50 m • • – – Advertising – Impulse buy, walk past – Discounts Find things: • Restaurants Movie theaters ATMs Gas Stations Significant Privacy Issues Telematics – Mapping and Directions • Weather forecasts – Truly local Find happiness ASAP
LBS Requirements • Client – Low client memory, thus J 2 ME, Mobile. PC, BREW, WML, XHTML… – Tolerant of unreliable connections – Works fast despite a slow CPU • Server – Fault tolerant: devices and connections are unreliable – Scaleable (add machines to improve throughput) • Roll over sessions to a working machine • Terminate sessions gracefully – Reasonably fast • Basic building blocks: – An accurate and fast positioning technology – An adequate internet connection – Some location data, e. g. maps, geocoding data, points-of-interest • Example GPS data acquisition application at http: //www. arecon. de/
Positioning Technologies • Cell Origin (“Cell. ID”) • Triangulation: – TDOA (Time Difference On Arrival, measured in phone), – E-OTD (Enhanced Observed Time Difference, measured in network), – AOA (Angle of Arrival, related to Cell. ID) • GPS (geographic position satellite) – Available today – Galileo (EEC 2007) – AGPS (requires surface carrier) • Rosum Digital TV based triangulation – requires surface carrier • Multimode handsets with microcellular underlay – Requires public or private LAN, e. g. BT, Wi. Fi-hotspot, Wi. Max
