Problems/challenges in WBAN technology are as follows:

• Data Management: WBANs are known to generate large volumes of data, so the need to manage and maintain these datasets is of utmost importance and critical.
• Data Quality: Data generated and collected through WBANs can play a key role in the patient health and care . It is essential that the quality of this data is of a high standard to ensure that the decisions made are based on the best information possible and reduced error.
• Security: Security is very important in WBAN. Because patients personal health data needs to be secured. It is important that data is only derived from each patient's dedicated WBAN system and is not mixed up with other patient's data.
• Invasion of privacy: People might consider the WBAN technology as a potential threat to freedom, if the applications go beyond "secure" medical usage. Social acceptance would be key to this technology finding a wider application.
• Cost: Nowadays patients opt for low cost health monitoring system.WBAN may be little high in cost than other health monitoring systems. So the cost of WBAN needs to be efficient for multiple acceptance.
• Consistent performance: The performance of the WBAN should be consistent.
