Computer Network – UTP and STP cable

UTP Cable
UTP Cable

Twisted Pair networking cable

Depending on the building configuration and the cable’s traject you will need to use UTP or STP.
STP stands for Shielded Twisted Pair and is mostly used outdoors or when running the cable near electromagnetic sources. The shield helps remove the unwanted interference. It has to be properly grounded otherwise it will make you communication worse. If you decide to go with STP, you need to use shielded RJ45 connectors and properly ground your switch. Using STP is not a do it yourself network installation.
UTP, Unshielded Twisted Pairs, is the most common networking cable and it produced in various grades/categories, (Cat 3, Cat 5, Cat 5e, Cat 6, and Cat 7) . The higher the grade the better the properties of the cable, hence the higher the speed that can be obtained on that cable. UTP cable can be purchased in large spindles at stores that specialize in cabling. The most common type is Cat 5 that supports networks up to 100Mb. Note that for a Gigabit network is not enough to use Cat 6 cable, you also need to use the right connectors and jacks, which is very often overlooked.

Deep Surplus

Networking UTP cable is a media that consists of eight wires twisted in pairs to reduce interference. The wires inside the UTP cable can be solid or stranded and they have different applications. The stranded wire cable is used for patch cables, which require flexibility and does not put mechanical stress on the jack or the equipment connectors and are able to withstand frequent plugging/unplugging from connections. The solid wire cable is used for long distances and connects in solid terminations such as patch panels, or the wall-mounted jack. The solid wire is cheaper, connects better and easier in patch panels and is a better match for long distances were flexibility of the cable is not an issue.
Never use flat cable for Ethernet cabling and avoid cheap UTP cable as you will run into various problems such as: wire is too thin and cannot be properly inserted, solid cable is too rigid and it breaks easily, very poor quality overall.

My Wireless Network Doesn’t Work When the Baby is Sleeping

Having a baby could affect your wireless communication?

Yes. Well, indirectly yes. Who has a baby and a wireless network will most likely have a baby monitor. We all like to spend our time blogging, or browsing the Internet while the baby is asleep, but we couldn’t blog a word if we didn’t keep an eye on the baby.

Many baby monitors will interfere with wireless networks. The wireless connection will work for most of the time and then suddenly it will stop working; after a wile will resume functioning properly. It could work without interruption but slow down transfer rates as network error corrections will be needed more than regularly.

How TO Eliminate Interference Between Baby Monitors and Wireless Networks?

Make sure you verify the band used by the baby monitor is not overlapping with the wireless band. If it does, you can change the channel on your Baby Monitor. How do you know if it overlaps? Read the instructions manual, and if you don’t have it, just try different channels on your baby monitor until you get a stable connection on your Network.
Another option would be to change the channel used by your wireless access point. If you have an old baby monitor consider buying a newer model, the newer models have less interference with your WiFi Network. I know that this sounds so un-green and consumerist, but I tested this and newer and more expensive models are better protected to interferences.

Is your Toddler Curious about the Little Box on the Wall?

If your child is a toddler he’ll be very curious about the different devices hanging around in your office and he will find your wireless AP. They will try, whenever they have the chance, to press any buttons and pull all the cables. Make sure, when your connection goes off, to check all the connections to the access point and to the modem. Consider to move your devices where your child cannot reach them.
