Mobility,Stacks,Not,Simple,Mos communication Mobility Stacks Not So Simple

The Nokia Mobile Company is the undisputed leader in mobile world, they have latest technology and capability to deliver world class handsets at no extra costs. The N series, E series and C series phones have already rocked the world with th But when we talk about the handsets, undoubtedly, Nokia is the King of mobile phone market and LG stood at the third position. In this article we are concentrating on Nokia E5 from the house of Nokia and LG GM360 Viewty Snap by LG Mobile Com

Mostenterprises today are investing, or are planning to invest in mobility today.From a branded applications, to BYOD, to a “mobile first”strategy, its different strokes for different folks. However, a lot of theseinitiatives come under management flak because of budget overruns. This happenstypically because when the budgeting and ROI calculations are done, allcomponents that go into the solution are not considered. Formost teams, Mobility is limited to having an app, or a BYOD policy. It isimportant that you understand the functional stack that goes into a mobilitysolution before we plan and design our solution. Unless you have the fullcomprehension of the layers and what goes into them, it is highly likely thatyou will end up under sizing or oversizing the solution.  Visibility Layer – As the namesuggests, this layer is all about visibility into the overall environment. Itconstitutes of two different types of views – the administration view and theuser view. The admin view is used by the tech team to do the management taskslike housekeeping functions (reporting, backups etc.), account management,service configurations etc. The user view is for the consumption of theenterprise applications and services. Being the topmost layer, it should havean integrated view of the layers below. Thislayer is essentially the entry point into the services offered as a part of theoverall solution. Solutions Layer – This is the corelayer where the actual services and applications exist. The entire technologystack that interacts with the backend systems and data layer exists here. Thisis where the integration between the device / endpoint and the underlyingsystems happens. It is critical that this integration is seamless to enhancethe user experience.  Whendesigning the solutions layer, all the use cases need to be understood andevaluated in deep detail. A lot of parameters need to be considered like thetypes of end devices, access logic, data transfer rates, platform support, typeand size of data (textual, images, documents, batch transfers, trickle controletc.) are some of the considerations for the design at this layer. Anotherimportant factor is whether the availability to the user is online only, oroffline as well. Device administrationlayer– Comparable to the standard MDM solutions this layer provides thefunctionality to track, control, and manage the end devices. In case thedevices are not company provided, then authentication becomes an importantfunction. In order to use the services offered, the device needs to beregistered with the access management solution to allow the traffic from thatparticular device into the solutions layer. Networking layer – this is the coredata communication layer, and is typically owned and provided by the carrier.However, if the enterprise has deployed a unified communications platform, thesame can be leveraged here. This layer needs to support multi-mode access, toenable access through Wi-Fi and other connectivity methods. The device layer – this is the endpoint layer, and is the most fundamental layer. It represents the highestcomplexity in the system, because while the layers above are enterprise ownedand managed, and are fairly standardized, this layer is employee / partner /customer owned, and is highly fragmented. The users are driven by personalneeds rather than the enterprise goals, and therefore, the technology andfunctional alignment to the larger enterprise strategy becomes a challenge.  Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable{mso-style-name:"Table Normal";mso-tstyle-rowband-size:0;mso-tstyle-colband-size:0;mso-style-noshow:yes;mso-style-priority:99;mso-style-qformat:yes;mso-style-parent:"";mso-padding-alt:0in 5.4pt 0in 5.4pt;mso-para-margin:0in;mso-para-margin-bottom:.0001pt;mso-pagination:widow-orphan;font-size:11.0pt;font-family:"Cambria","serif";mso-ascii-font-family:Cambria;mso-ascii-theme-font:minor-latin;mso-hansi-font-family:Cambria;mso-hansi-theme-font:minor-latin;}
