3 Multi-Channel Challenges and Requirements

Implementing a cost-effective single radio multi-role multi-channel system has many challenges and should meet some mandatory requirements in order to overcome those challenges. This chapter will first describe basic concepts of a multi-role system like what is role switch protection and what are the tools provided by the IEEE 802.11 specification to enable it. Then it will elaborate on how those tools are used and related to the multi-role multi-channel challenges and requirements.
