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.
Check out Aqua Zumba! Aerobics class. Zumba is a mix of aerobics and Latin dance, so it only makes sense that the two would be similar in burning calories. A specialized group fitness class for older adults, such as SilverSneakers Cardio Circuit, should burn about 200 calories per half hour. So Zumba is a little more intense than that. Itâs all about finding the class and style that best works for you.
