Solve : Better network method? |
|
Answer» What is the better network method? I find, based on speed tests, that I can get the same speed via wireless connection that I can from wired. At least, this is what I've experienced at home, using a D-Link DI-524 router. I'm sorry, I have to strongly disagree. When you enable the security options for the wireless mode, your speed will dramatically drop. Without secure connection I don't recommend to anybody to use a wireless network. Wired connection, at 100 Mbps, is faster than any home consumer wireless network. Of course, if the switch/router is a "break", is too SLOW at FORWARDING packets inside your LAN, then maybe yes, the wired and wireless experience may be the same. But otherwise, the wireless LAN is far slower than the wired LAN. We don't talk about WAN connections here. Because ussually WANs connections are far slower than LAN. In a LAN environment the normal (theoretical) speed is at least 10 Mbps (the actual normal speed is 100 Mbps); for a WAN connection we start talking from dial-up speeds (modems) of 33 Kbps (or less) and increasing towards Mbps. You may have a connection of 512 Kbps or more (ADSL, fiber optic), let's say a few Mbps per second, but most usually you will have a slower WAN connection than your LAN connection. In this case the bottleneck will be the WAN connection, and there will be no difference if we connect to 512 Kbps WAN from a LAN where we have a 11 Mbps wireless connection or a 100 Mbps wired connection. The poll misses the option: "It depends on the case". Not all the time the wired connection is better than the wireless connection. They solve different CASES: I don't see anyone moving a wired connection throughout his house. Here wireless is better, you just grab your laptop, go in bedroom and voila, network connection available. Gee, let's go to kitchen; network connection "follows" us With wired... Plug the cable, unplug the cable, move the cable, take care of the cable, don't step on the cable, don't cut the cable, keep away the little dog (or cat) from the cable or he will try his teeth on etcQuote The poll misses the option: "It depends on the case".

Where I work we use gigabit connections for each plant and fiber to connect them together. If we were to use wireless, we would get a max data transfer rate of 11mbps since each site is several miles apart and they don't have many options for anything faster at those distances. However, we also rely on wireless so that the plant operators can take a pen tablet out into the plant and make changes on the spot. Can you image them dragging a 300' ethernet cable behind them to do that? |
