AT&T Wireless Case – ACCT 503 1. [10 points] Describe the cost behavior in the wireless industry. What are the implications of this cost behavior for cost-volume-profit (CVP) relationships? Cost behavior is how a company’s costs change given a change in that company’s activities. Variable costs are costs that change proportionately with the changes in a company’s activities. In contrast‚ the costs that do not change with a change in a company’s activities are known as fixed costs.

1. Introduction The increasing interest in wireless sensor networks can be promptly understood simply by thinking about what they essentially are: a large number of small sensing self-powered nodes which gather information or detect special events and communicate in a wireless fashion‚ with the end goal of handing their processed data to a base station. Sensing‚ processing and communication are three key elements whose combination in one tiny device gives rise to a vast number of applications

Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration include electromagnetic radiation in the form of microwaves or lasers
