Cabling Your Home For Computer Network Still A Requirement

Cabling Your Home For Computer Network Still A Requirement



Cabling your home for computer network - still a​ requirement?
Cabling your home for computer network - still a​ requirement?
With proliferation of​ wireless networking and communication equipment it​ is​ oh-so-tempting to​ cut the​ cord and save a​ significant sum of​ money in​ the​ process .​
But is​ everything that a​ regular computer networking user needs can be done using just wireless network? Let’s take a​ look at​ some pros and contras:
1. One important advantage of​ having a​ cabled network is​ the​ available bandwidth or​ simply speed .​
At the​ present point in​ time the​ speed of​ connection via a​ simple and inexpensive CAT5E cable can be 1000Mbit/sec,​ whereas the​ best that IEEE802.11g (one of​ the​ many flavors of​ Wi-Fi) can offer is​ only 54Mbit/sec .​
It may not seem so significant if​ you think you are only browsing Internet,​ and the​ DSL speed available to​ you is​ 1.5Mbit/sec .​
However,​ if​ you need to​ print via your network connection on​ a​ remote printer,​ you should realize that the​ print jobs,​ depending on​ the​ amount of​ graphic data in​ them,​ can easily reach dozens and even hundreds megabytes .​
Since 1Byte=8bit one 100MByte print job will take 15 seconds (and in​ reality this time can be much longer) to​ transmit via a​ Wi-Fi wireless connection,​ and this time shrinks to​ mere 1 sec or​ less on​ wired 1000MBit/s Ethernet connection .​
Same principal applies to​ transferring files,​ backing up files on​ other computers in​ the​ network etc.
2. It is​ not possible today and with all probability will not be possible in​ the​ future to​ transmit power needed for your networking device via the​ wireless link .​
Unless,​ of​ course,​ you would be willing to​ be subjected to​ very high levels of​ microwave radiation .​
Thus a​ device that was marketed to​ you as​ un-tethered will in​ fact be very much tethered via the​ power cord or​ will have to​ be re-charged every so often .​
The power requirements are increasingly important for devices that are expected to​ be always online,​ such as​ phone sets .​
Therefore it​ is​ best to​ have it​ connected via a​ cable that can deliver both power and the​ communication signal at​ the​ same time.
3. Wireless communications are very much proprietary and require whole gamut of​ conversion equipment to​ transmit multi-media signals .​
The same CAT5E cable can without any modification support phone,​ computer network,​ balanced line level audio signal,​ baseband video signal as​ well as​ host of​ other,​ more specialized,​ control applications’ signals .​
With inexpensive adapters called baluns the​ same cable can carry significant number of​ channels of​ broadband television or​ carry a​ baseband video,​ such as​ security camera output,​ through great distances .​
All of​ those applications,​ except the​ computer network of​ course,​ will require specialized expensive conversion equipment if​ they needed to​ be transmitted via a​ Wi-Fi link.
4. The cost benefit of​ not running wires around the​ house is​ not as​ simple as​ issue as​ it​ seems .​
Having installed a​ wireless network at​ home you have only eliminated the​ need to​ wire for a​ single application – computer network .​
a​ modern home,​ however,​ requires all kinds of​ wiring to​ run even without regard to​ computers .​
The power and phones are obvious examples,​ as​ well as​ thermostats and security systems .​
Pre-wired speakers are common and most homes today have intercom systems as​ a​ desirable option,​ and those also require extensive wiring .​
It is​ very likely that the​ same contractor running the​ intercom or​ security cables is​ qualified to​ run computer cables – CAT5E or​ better .​
If you are building a​ home,​ you should definitely check if​ computer cabling option is​ available in​ your new home,​ and our advice is​ to​ go ahead and purchase it​ before the​ walls close .​
It is​ going to​ be a​ pretty involved and expensive procedure to​ install the​ cables later .​
As an​ added cost benefit of​ a​ wired computer network you will find that all modern computers ship with wired Ethernet network interface card included,​ and the​ latest models ship with 1000MBit/sec cards that are essentially free for the​ computer’s owner.
There are multiple sources of​ information available on​ proper planning and design of​ a​ residential cabling for voice,​ data,​ audio,​ video and other applications .​
One of​ the​ best sources is​ the​ TIA/EIA-570B standard,​ most resent release of​ which has been published in​ 2004 .​
The standard outlines recommended types of​ the​ cables,​ principals of​ cable distribution in​ a​ single- and multi-dwelling units as​ well as​ recommended amount of​ cables to​ be installed based on​ the​ size of​ the​ house.
In conclusion,​ cutting the​ wire seems like a​ step forward,​ some sort of​ liberation of​ computer from the​ bonds of​ the​ infrastructure .​
I​ would caution the​ reader,​ however,​ to​ take a​ more balanced and informed approach before joining the​ wireless revolution .​
There are still (and will remain in​ foreseen future) sound reasons to​ include properly designed cabling system into the​ list of​ your dream home options.
