Guaranteeing Quality of Service (QoS) in wireless network is a challenge. This is due to the fact that the signal travels without a physical transmission medium. Therefore, it will be prone to all kinds of transmission impairments including atmospheric noise, physical obstructions found in the signal's path, multipath propagation, interference from other systems and terminal mobility. The high bit error rate in wireless networks, which can be 10 times than that in wired networks, makes it difficult to offer guaranteed quality of service over the wireless link. Among the challenges in wireless networks is limited bandwidth and how to achieve the required quality of service. This paper presents a method to implement DiffServ with Class Based Queueing (CBQ) in wireless networks. Various experiments have been conducted under different settings and operating conditions. Theoretical analysis and experimental observations indicate that: (a) it is feasible to use the strategy to separate the uplink and downlink QoS mechanism for the wireless link, (b) Diffserv can be used to provide QoS for downstream data in the wireless link, (c) for upstream data, it is needed to have resource reservation or to let mobile node know the available bandwidth in order to avoid having the mobile node competing for wireless link resources which causes the bandwidth to be wasted, and (d) a better mechanism should be used for collision detection in the wireless link.
