a local county sheriffs department has received a grant to upgrade its existing communication system and the system must satisfy certain requirements. First, there must be complete coverage throughout the county. This county includes metropolitan areas as well as desert and mountains that are often outside normal radio or wide-area Wi-Fi coverage. About 95 percent of the county is within cell phone coverage, and 5 percent is in uncovered mountainous areas. Officers normally have access to customized laptops in their vehicles. However, some officers are required to patrol ATV trails and campgrounds. Those officers will still need to be connected with a portable computing device. Hence, another requirement is being able to use smaller portable devices. Your assignment: Recommend a communication and network solution for the county sheriffs department. It can be any combination of Internet, VPN, Wi-Fi, telephone, and satellite communication. The applications can be custom built, with device-specific or HTML-based user interfaces. Although HTML tends to be more versatile, it has draw-backs regarding security; display can also be an issue on devices that dont have browser support. As always, the budget is tight, so your solution should be as economical as possible. Develop a network diagram that depicts your proposed solution. Also, explain your solution and justify your design.
