Enterprise Mobile Computing:
A Case Study
Presentation Abstract The explosive growth and evolution of smart phones and other mobile computing devices is redefining the way businesses interact with their customers and employees. OCI will present a case study about a local service business that had outgrown its ability to effectively manage its mobile workforce via phone, FAX, and personal computer. In just a few weeks, OCI developed a native smart phone application and hosted web service to enable scheduling and dispatching of workers, communications with workers at remote sites, recording of vital information about work performed, and integration with existing business processes and data. The presentation will discus how this client leverages huge public/private investments in communications infrastructure, GPS, mapping and street navigation systems, hosted services, and an open mobile operating system, to completely transform itself. The case study will explore the salient business drivers, architectural objectives and constraints, applicable standards, technology, and platform choices, and application design and implementation considerations of the solution developed by OCI for the small business.

Mobile computing
Mobile computing
is a form of human–computer interaction by which a computer is expected to be transported during normal usage. Mobile computing has three aspects: mobile communication, mobile hardware, and mobile software. The first aspect addresses communication issues in ad-hoc and infrastructure networks as well as communication properties, protocols, data formats and concrete technologies. The second aspect is on the hardware, e.g., mobile devices or device components. The third aspect deals with the characteristics and requirements of mobile applications.
Limitations;
Insufficient bandwidth: Mobile Internet access is generally slower than direct cable connections, using technologies such as GPRS and EDGE, and more recently HSDPA and HSUPA 3G networks. These networks are usually available within range of commercial cell phone towers. Higher speed wireless LANs are inexpensive but have very limited range.
Security standards: When working mobile one is dependent on public networks, requiring careful use of VPN. Security is a major concern while concerning the mobile computing standards on the fleet. One can easily attack the VPN for a very huge number of networks interconnected through the line.
Power consumption: When a power outlet or portable generator is not available, mobile computers must rely entirely on battery power. Combined with the compact size of many mobile devices, this often means unusually expensive batteries must be used to obtain the necessary battery life.
Transmission interferences: Weather, terrain, and the range from the nearest signal point can all interfere with signal reception. Reception in tunnels, some buildings, and rural areas is often poor.
Potential health hazards: More car accidents are related to drivers who communicate with mobile devices. Cell phones may interfere with sensitive medical devices. There are allegations that cell phone signals may cause health problems.[citation needed]
Human interface with device: Screens and keyboards tend to be small, which may make them hard to use. Alternate input methods such as speech or handwriting recognition require training
