4 THE NIRVANA PHONE CONCEPT OVERVIEW As SmartPhnes cntinue t becme mre capable, fast netwrks becme mre pervasive, and virtual desktps like Citrix XenDesktp g mainstream, it is becming increasingly pssible t use a SmartPhne t perfrm tasks previusly limited t laptps and desktps. Desktp virtualizatin is a cncept that delivers a cmplete Windws desktp experience as an n-demand service t any user, anywhere. A virtualized desktp is stred n a central server r blade PC in the data center, instead f n the lcal client device. When users wrk frm their lcal client device, all f the prgrams, applicatins, prcesses, and data are kept and run centrally in the data center. This enables users t access their desktps n any capable device, such as a traditinal desktp cmputer, laptp, thin client, r SmartPhne. The fllwing illustrates the cncept f desktp virtualizatin: Figure 1: Virtual Desktps The nirvana phne cncept allws a user t use their small frm factr device when n the mve r in the ffice t access business applicatins and data. The bjective f the nirvana phne is t enable a user t mre fully leverage their SmartPhne as their primary cmputing device, and enable the cnnectin t cmmn larger frm factr peripherals such as full screen mnitrs, mice, and keybards. When the nirvana phne is cnnected t such peripherals, the use cases are extended frm nrmal mbile applicatins t the enhanced use f full desktp and larger reslutin applicatins , Open Kernel Labs and Citrix Systems, Inc.

5 The fllwing is an illustratin f the nirvana phne cncept: Figure 2: Nirvana Phne Cnnectivity Illustratin KEY FUNCTIONAL AREAS OF FOCUS There are several capabilities in tday s SmartPhnes that need t be develped t realize the visin f the nirvana phne. These include: Vide-ut A few SmartPhnes have vide-ut t supprt a large external mnitr, but the reslutin is limited in sme cases and usually fcused n media utput t televisin-type mnitrs with NTCS r PAL reslutin. A nirvana phne implementatin shuld fcus n cmpatibility with cmmn cmputer mnitrs and prjectrs and the cmmn reslutins and physical cnnectrs assciated with these devices. Enhanced graphic drivers are als required t supprt the attached mnitrs as an extended graphics space, and nt just a mirrr r replacement f the device s native screen. Audi Existing capabilities that cnnect SmartPhnes t external audi devices like headsets r pwered speakers wuld be utilized. Keybard and Muse T allw a user t be fully immersed int nirvana phne use, mre than just a bigger screen is required. The user must als be able t leverage full-sized input peripheral devices such as mice and keybards. Bluetth capability including cnnectin t industry standard Bluetth keybard and muse is required. Optinally a nirvana phne dcking statin culd be prvided t allw cnnectin t a standard USB keybard and muse. Citrix Receiver Client sftware that allws the user t securely access crprate applicatins, desktps, and data frm their mbile device and utput this data t either the device s lcal screen r vide-ut t an external mnitr Dcking Statin (Optinal) An assciated dcking statin wuld allw dcking a nirvana phne t be dcked and prvide instant cnnectivity t pwer, vide, and ther peripherals.

6 Use cases fr the nirvana phne include the fllwing tw high level examples: Mbility and Flexibility Many users want t travel lighter and have the flexibility t leave their laptp at hme n trips all tgether. It s their persnal chice if and when t use a nirvana phne. Fr example: A traveling salespersn may want t travel light and use their nirvana phne t cnnect t a prjectr t deliver a sales pitch, allwing them t leave their laptp at hme. A mbile emplyee can cnnect their nirvana phne in Internet cafes in the airprt and the flat screen TV in their htel rm t get a full desktp use envirnment. An emplyee that wants t Bring their Own Device (BYOD) t the wrkplace. The nirvana phne enables emplyees t utilize their wn device safely n a public 3G netwrk that is islated frm the crprate netwrk. Cst Cntrl Cmpanies are lking fr cst reductin methds and may decide t increase the ROI n the SmartPhnes they have bught fr their emplyees by leveraging them as nirvana phnes t replace laptps r desktp systems and eliminate the maintenance assciated with laptps and desktps. Fr example: A cmpany decides that the cst f purchasing and supprting a full laptp fr each f their emplyees is t high, and adpts a plicy f nly supplying defined jb rles with a nirvana phne as a laptp alternative. A service cmpany decides t save mney by eliminating laptps equipped with aircards in their service vans and replace them with nirvana phnes that cnnect t a simple LCD screen and a Bluetth muse and keybard t leverage the data netwrk already paid fr n the smart phnes, lwering their ttal cst f wnership (TCO). A hspital prvides nirvana phne htspts thrughut the hspital t which emplyees can cnnect their nirvana phne. This allws them t experience a desktp-like cnnectin t hspital and patient data thrughut a hspital at a lwer cst f nly a mnitr, muse, and keybard fr each htspt. A cmpany sets up nirvana phne capable ffice hteling that allws users t cnnect their nirvana phne t full-size peripherals (mnitr, muse, and keybard) in any available cube envirnment and get an ffice desktp-like experience. SOLUTION REQUIREMENTS NIRVANA PHONE NATIVE DESIGN A native nirvana phne design requires that peripheral drivers fr each f the key functinal areas wuld need t be develped fr each device platfrm, and in sme cases fr the specific device. The Citrix Receiver and the drivers wuld run in the cntext f the device s native OS. Althugh this design may seem simpler, it des nt scale well acrss multiple platfrms. Designs that leverage a mbile hypervisr culd prve t be mre effective , Open Kernel Labs and Citrix Systems, Inc. Page 6

7 The fllwing illustrates the basics f the native design: Figure 3: Nirvana Phne Native Design NIRVANA PHONE MOBILE HYPERVISOR REQUIREMENTS Mbile hypervisrs, such as the OKL4 Micrvisr frm Open Kernel Labs, can be used t enhance the nirvana phne native design by allwing the cre architecture t be used acrss multiple mbile device platfrms. Mbile hypervisrs can abstract the majrity f the nirvana phne functinality int a secure cell, and then allw that cell t run in cnjunctin with a device s native perating system (OS). The native OS nly needs t knw that the nirvana phne functinality exists in a secure cell n the device and hw t start that functinality when requested. The cell handles the driver integratin, services, and all f the nirvana phne peratins independent f the native OS, regardless f the OS type. The OKL4 Micrvisr enables a secure, islated envirnment fr the Citrix Receiver technlgy and the device driver sftware that enables the external devices. Benefits f an OKL4 Micrvisr-based implementatin include: Imprved Security Using OKL4 prevents the native device OS envirnment frm accessing the infrmatin flwing between Citrix Receiver and crprate IT assets. This remains true even if the security f the native OS envirnment has been breached. Reduced Develpment Effrt Where the native OS design apprach requires OS-specific device drivers fr each f the external devices (display mnitr, keybard, and muse), a single OKL4 native device driver fr each device type can be reused with several different SmartPhne OSes. The savings ffered by SmartPhne OS-independent device driver implementatin are realized nt nly during initial develpment but during nging maintenance as well , Open Kernel Labs and Citrix Systems, Inc.

8 Device Sharing Flexibility - When the nirvana phne is dcked, in additin t the use f Citrix Receiver, the user can still use the phne as a phne. At a minimum the phne needs t present a UI n the mnitr and thrugh the muse/keybard/micrphne/speakers. In ther wrds, the Citrix Receiver and the nirvana phne OS share thse devices. By virtualizing shared devices and prviding the ability t apply plicies n hw sharing is implemented, the OKL4 Micrvisr ffers a very flexible framewrk fr device sharing This flexibility allws the "nirvana phne" user t run native SmartPhne OS applicatins and at the same time access enterprise applicatins frm a memry efficient and secure OKL4 cell. Althugh the Citrix Receiver runs in islatin frm the native device OS, a launcher applicatin n the native OS initiates its executin. As illustrated in the fllwing figure, the Citrix Receiver is running in an OKL4 Micrvisr secure cell. Figure 4: Nirvana Phne Device OKL4 Design (Dcked) DEVICE REQUIREMENTS Fllwing is a brief list f the device requirements: Vide Output Must include HDMI, VGA, USB, r ther industry standard mnitr frmat. Als, the emerging wireless vide standard(s) shuld be supprted. Nte that NTSC r PAL are insufficient, based n the screen reslutin requirement. Screen Reslutin Minimum reslutin 800 x 600. A virtual graphics driver (VGD) running n the nirvana phne extends the usable graphics display space t a Virtual Graphic Display area, separate frm the device s native display , Open Kernel Labs and Citrix Systems, Inc.

NIRVANA PHONE ALTERNATIVE ARCHITECTURES There are als alternative architectures that can achieve the same desired result f a nirvana phne cnnecting t a full-sized display mnitr t imprve the device usability while statinary. These alternatives can include wireless cnnectins between the nirvana phne and the display, which can be an attractive alternative. Hwever, it als means that a matching r cmpatible hardware device is embedded r attached t the display. These alternative architectures will be dcumented in a separate specificatin. CONCLUSION This dcument utlines cre requirements fr a nirvana phne SmartPhne, including accelerated implementatin in partnership with Citrix strategic partner, Open Kernel Labs. SmartPhne prviders that develp a device which meets these requirements will achieve a new level f functinality and desirability (by users and IT) that is unmatched in the current marketplace , Open Kernel Labs and Citrix Systems, Inc.
