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.
It is not unusual to see aerobic dance and Zumba, a form of dance to Latin music, offered in neighborhood gyms and community centers. Both have similarities but some differences for participants.
Zumba is a form of fitness class in which you burn off calories by dancing to different kinds of lively tunes, often Latin-American inspired such as salsa, merengue and samba, but also other types of modern music like hip hop and Bollywood (music from the Indian film industry).
