Reliability of mobile phones

The paper addresses reliability aspects of mobile phones, also known as cellular phones. Mobile phones have been in use for about a decade. Early models were low in technology and usage was limited. However, the technology of phones has been improved significantly during the last few years. The market demand has been increasing in a similar manner over the last few years. It is anticipated to increase this trend in the foreseeable future. Aspects covered include those considered at different stages of the product development: design and development; reliability demonstration; and environmental testing. Also considered are commercial issues that effect the product reliability.
