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 an effective workout for nearly every type of exerciser, with its flowing and fun dance steps to upbeat music. But as in any fitness program, injuries can occur. âThe world of Zumba is excellent, but over the years Iâve seen a number of Zumba injuries,â says Dr. Michael R. Marks, American Association of Orthopaedic Surgeons spokesperson and Vice President of Business Development at Norwalk Hospital in Norwalk, Conn.
