N2 - This paper quantitatively investigates the relationship between physical transmission rate and network capacity in multi-radio multi-channel wireless mesh networks by using mixed-integer linear programming to formulate the joint channel assignment and routing problem. The numerical results show that the rate lower than the highest available one can improve the network capacity due to increased connectivity. It is also shown that the lower transmission rate is able to utilize abundant channels more effectively due to the higher degree of freedom in channel assignment. Finally, it is shown that joint rate, channel assignment and routing improves the network capacity further.
