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.
One day I got to my class, and I realized Iâd left my regular aerobics music at home. I looked in my bag, took out some salsa and merengue tapes, popped them into the sound system, and taught the first-ever ZumbaÂ® class. After a career as a trainer and choreographer in Colombia, I decided to make the big move to the United States.
