Theoretical vs. Actual Network Speeds. The performance of Wi-Fi networks practically never approach these theoretical maximums. 802.11b networks, for example, generally operate no faster than about 50 percent of theoretical peak, around 5.5 Mbps. Likewise, 802.11a and 802.11g networks generally run no faster than 20 Mbps.

Zumba can be fun and safe for all ages and fitness levels since the moves can be modified to your level of fitness.nspired by Latin music, Zumba is a low-impact, high-energy dance exercise.
