A "handoff" is a term used in wireless communications to describe the process of a cell phone moving from a coverage area of one base station to another. Each base station has multiple channels (called color codes) that allow it to communicate with the cell phone. The Journal of Engineering, Computing and Architecture (Vol. 3., 2009) published a study of cell phone handoff behavior. During a sample driving trip which involved crossing from one base station to another, the different color codes accessed by the cell phone were monitored and recorded. The table below shows the number of times each color code was accessed for two identical driving trips, each using a different cell phone model. (Note: The table is similar to the one published in the article.) Suppose you randomly select one point during the combined driving trips.

\begin{aligned} &\text { Color Code }\\ &\begin{array}{lllrll} \hline & \mathbf{0} & \mathbf{5} & {\text { b }} & \text { c } & \text { TOTAL } \\ \text { Model 1 } & 20 & 35 & 40 & 0 & 95 \\ \text { Model 2 } & 15 & 50 & 6 & 4 & 75 \\ \text { TOTAL } & 35 & 85 & 46 & 4 & 170 \\ \hline \end{array} \end{aligned}

a. What is the probability that the cell phone is using color code 5 ?

b. What is the probability that cell phone is using color code 5 or color code 0 ?

c. What is the probability that the cell phone used is Model 2 and the color code is 0 ?

Question

Wireless Technology Radio frequency identification, satellite communications, and cellular networks are used for physical distribution systems and inventory storage. Describe how one of these forms of technology is used in the delivery of products or inventory storage. Present a short description of how this technology is used in shipping to your class.

Solution

Cellular networks are used every day in the physical distribution world. Cell phones are used to communicate when on the road for truckers, and the trackers in phones can keep track of where your delivery is located. Cellular networks help to keep each leg of the distribution chain in order by keeping everyone in touch. In terms of inventory storage cellular networks are also useful because often times warehouses are in remote locations and you need to have a cell phone with you when traveling there.
