That means that there are no other users sharing the cable whose data packet could collide. When a collision occurs on a wireless network, based on how the protocols are designed, each user's packet is lost, a random timer makes them wait for a free time to transmit, and then each must retransmit the information. The wireless network can provide speeds of only 11 Mbps shared between its users, while hardwired networks operate with a dedicated connection at 100 Mbps switched between two points. Many advancements in LAN technology are pushing the speeds that data travels. A wireless network, based on transmission speeds, performs like the hardwired networks of ten years ago.
Hardwired networks can grow without installing additional cables.
Each horizontal cable can have a switch connected at the classroom for a cascaded network design. Design standards recommend only one cascade level. The down side of hardwired networks is that they are difficult to reconfigure. The cabling system should not be moved and manipulated once installed and tested. So when a space changes, new cables are often required.
