Hello Experts,
I want to sugest to my IT Boss about us shifting to Wireless Networking in our entire Company so as to scrap off all these cabels in our offices. Can you please advice me if that's the best way to go and what are the merits and demerits of wireless networking over cabled network. Plus on
its ease to implement it. Your comments will be highly appriciated.

Also, wireless is a lot slower and can be unstable

by Slayer_ In reply to IS WIRELESS NETWORKING BE ...

Someone turning on a microwave can knock out the whole office.

And the wireless theoretical max speeds never happen because of the overhead required for wireless to be reliable.
a 100mbit Wired LAN will operate at around 90% usually.
a 300mbit wireless LAN will operate at around 20%-50% usually.

You can test this if you want to, transfer a file from a wireless system to a wired system across a hub/switch/router.
You will see the wireless will be running at maximum, but the wired will be barely active at all, even from 300wireless to 100 wired.

In my experience at home, my 54mbit wireless actually ran at around 12mbit even if you were a foot away from the signal source/destination. Only 22%. If this is correct, than a 300mbit wireless will actually run at 66mbit. A 750 will actually run at 165mbit. And that's if you have perfect signal and no congestion.
Hopefully these figures are wrong, but my point is, wireless is for mobility, not speed, not reliability. Desktops should remain wired.

While wireless is very convenient, and can be cheaper to install, keep in mind that security, reliability and speed are going to sacrificed.

I wouldn't use wireless in a critical system at all, unless there is simply no access to a wired system. I would even provide a drop for places where a laptop is often used.
I believe you'll find it to be well worth the additional investment.

A wireless system with a good password and tough encoding should be made available for those locations where wired isn't practical, and a *separate* password protected system for visitors. In maximum security situations, the visitor's system should be on a separate router and ISP line to insure no one can easily cross-connect to your secure net.

Another Cost for Wireless

by TheChas In reply to IS WIRELESS NETWORKING BE ...

In addition to the points stated by Slayer and markp24, there is the cost of adding wireless adapters to desktop computers and older printers.

The only real benefit of a wireless network in a business environment is the ability to use a laptop in a portable mode. Be it a conference room, or when multiple team members need to work together on a project.

Most businesses run a mixed network, with wired networking and 2 or more wireless networks.

1 wireless network usually offers only Internet access and may be unsecured.

Any business wireless networks should be highly secured and require more than just a general password to complete the connection.

And, don't forget all the APs you'll probably have to buy for good coverage, plus securing all of them.

Really, having cables is such an issue? They are way better.

Just an extension on one of the above

by OH Smeg Moderator In reply to IS WIRELESS NETWORKING BE ...

Wireless depending on the maker of the Devices and the construction of the building can be flaky. You also need to understand Wireless Propagation and while you can have a work station 30 feet from the WiFi Access Point it may not get a strong signal and may be even unable to connect.

It all depends on the position and anything between the 2 points.

Also again depending on the WiFi Makers Devices the Signal can travel up to 500 Meters and be quite usable so it's possible that someone outside the building up to .5 of a Kilometer away can log into the WiFi LAN and access your data or Internet connection. Depending on your location you may also be responsible for any downloads so if someone outside the office was to download Kiddy Porn or Bomb Making Directions over the WiFi the business would be in at best an difictult position trying to explain why this happened. Even with the best security in place this can happen and the Term War Driving was coined to describe this.

So it's possible that you not get a strong signal 30 feet away inside the office and you'll get a great signal .5 of a Kilometer away outside the building. Also depending on the business it may also have procedures in place to comply with Legislation or Best Practices for that Industry which prevent the use of Wireless networking.

No question. No contest.

by Snarg In reply to IS WIRELESS NETWORKING BE ...

If better means more reliable, easier to manage, and easier to diagnose and fix when problems do arise, then there's no question, and no contest. One has only to consider why cables are the first resort when wireless goes down.

What to choose; Wireless or Wired?

by rubendlct In reply to IS WIRELESS NETWORKING BE ...

My personal experience tells me that a combination of both, wired and wireless networking is best (and a must) to have in any network requiring remote access. Wireless is best for the easiness of moving around in the office with laptops, Iphones and other remote devices. Wired is best for the purpose of security, troubleshooting, maintenance, and reliable communications.The combination of both systems provides easiness of communications and increases production where the enterprise can be accessed remotely by any authorized employeein a secured wireless network instead of having to go into your office and sit down to jug don and send an important and time critical electronic message (e-mail).
