120	120	The UDP stream continues across frequency hops without interruption because the Wi-Fi client knows and honors the Channel Switch Announcement. Because of the lossy nature of multicast beacons, we are not able to dramatically speed up the hopping rate with this architecture and still expect the STA to reliably track the frequency hopping changes of the AP.

122		In the next section, the [wiki:802.11/wlan_exp/app_notes/tutorial_hop_mac/fast_hopping Fast Hopping Approach], we will take a radically different approach to the problem and break compatibility with commercial Wi-Fi devices to enable much faster frequency hopping.
	122	A 10 second dwell on a single frequency is very slow. As a rough comparison, Bluetooth performs a hop every 625 µs. While we could reduce the value of {{{HOP_INTERVAL_NUM_TBTT}}} to speed our hop rate up, we would do so at the cost of reliability since a STA needs to properly decode a beacon to know where and when it should hop.
