to be considered. C in the 5GHz DFS channel, other signal transmitter (such as radar system) also need to take into account.
However, the problems caused by non-802.11 disturbances are more difficult to diagnose or avoid. When encountering such faults, the traditional approach is to use hand-held signal analyzer for sampling, this method has certain limitations. Scattered disturbances may not be transmitted at the time of sampling. In noisy high density places, the spectral map is difficult to
. If such ICMP messages are repeatedly sent, the device may become inaccessible to the network. The IETF document also outlines another DoS attack method that uses the path's largest transmission unit to discover PMTUD. PMTUD is a mechanism of ICMP to process error messages.Cisco indicates that only routers and other devices running IOS with PMTUD enabled are under this attack. It indicates that ICMP "hardware error" message attacks are invalid for Cisco devices. However, all versions of IOS10.x

Several major vendors, including the Aruba network and Cisco Aironet, provide security kits to verify that most devices are logged on to the wireless network, said Terrill. These toolkit are configured with the latest tools for virus protection, firewall, and scanning other security vulnerabilities. Other products, including radio frequency sensors, also provide protective measures. However

companies should consider their network design and existing infrastructure when planning to deploy the second wave of 802.11ac standards in the future.
The switch capacity has become a problem when adapting to the first wave of 802.11ac standards, because the 802.11ac standard can support 1.3 Gbps bandwidth, and most Access Points flow out with 1 Gbps bandwidth. Most enterprises are restricted by environmental factors, such as interference, which makes the first wave of 802.11ac unable to reach

However, he does not think that the user needs to wait for the release of Wave2 for deployment. "Many users looking forward to 802.11ac are facing the issue of waiting for the release of the 2nd generation standard. Cisco believes that such a wait is unnecessary in most cases. If you do not deploy 802.11ac, your system capacity requirements
