Making Wireless, Not Ethernet, the Heart of the Network
GMGruman writes "As mobile devices enter the workplace and latch on to Wi-Fi networks — along with devices such as HVAC sensors and videoconferencing that most people don't even realize use Wi-Fi — the typical wireless LAN is unable to cope. What needs to happen, argues Aberdeen Group's Andrew Borg, is a rethink of the wireless LAN not as a casual adjunct to the wired LAN (the typical mentality when they were first set up) but as the corporate LAN itself."
High latency, low throughput, and a shared collision domain.
What's not to like?
And where, exactly, do you suggest I plug in my iPad? The MacBook Air requires a separately purchased dongle to connect to a wired LAN.
Your solution assumes that a majority of devices continue to be developed with an ethernet port. As we move towards thinner, lighter laptops, I doubt Apple will stand alone in manufacturing devices that no longer have an easy way to connect to a wired network.
Ye cannae change the laws of physics!
Seriously, though... wireless has serious inherent disadvantages. Susceptibility to interference, a single collision domain, much lower bandwidth in the analog sense. It's good for mobility, but if you try to run a whole site-LAN on wireless it just wouldn't work - even if you utilised the 800MHz, 2.4GHZ and 5.0GHz bands all at once. Maybe if you put little 60GHz nodes in every room, but it'd be far too expensive.
One of the advantages of a wired network is that the data only leaves the premises at well defined locations that you control. With wireless networks it floats over the aether in all directions. And before you can say "encryption will protect me", think about how easy it would be to build a transmitter running on the same frequencies as the wireless network and sit that just outside the company and pointed inwards - instant denial of service attack with zero traceability.
I am Slashdot. Are you Slashdot as well?
You are using an iPad on a corporate LAN and accessing "boatloads of data"? Haha.
Some people have real work to do.
Perhaps then it's time to refine the overly large rj45 plug into something that will accommodate smaller form factors. Call it Ethernet micro. Most of the connector is wasted plastic anyway.
Printers? Video surveillance? HVAC? Electric meters? Why are these things using WiFi, when they rarely move and are always plugged into an external power source?
Palm trees and 8
These are the three things that WiFi still can't compete in against a wired network.
Even the most secure wireless is still much more susceptible to attack then a wired network. Even with the most modern access control and protection methods (which are neither cheap nor convenient) the sheer massive avenue of attack WiFi presents creates a problem for many large corporations. Ask JPMorgan Chase how much WiFi connectivity they have. Or pretty much any US Government building.
Even if you do as the article suggests and call in an expensive contractor to map out the best locations for access points, you have to find out if it's even feasible to run network and power to that location. Even with the best-possible placement you are going to have dead zones, and the size and location of dead zones will vary depending on the devices used. My Toshiba laptop got service in places a virtually identical Macbook did not- let alone the poor wireless reception most mobile phones and devices provide. So you have to deal with irate users, and try to find places to install additional access points to cover the dropped zones.
When I worked for a small non-profit K-12 school, during teacher inservice days I always had to install 2 additional access points in the gym so that the teachers could all connect on their laptops, as the single AP currently serving the gym was not sufficient. Even then, transferring any large file from the server or online either brought the network to a standstill or required tethering each machine to an ethernet cord to do the transfer. Most high-tech oriented conferences, the wireless is all but useless if it's available publicly, due to the hundreds of devices all connecting within a limited frequency space and bandwidth. There is just not enough bandwidth in a small space available to deal with more then a handful of data-rich connections. Spread across multiple spheres of AP reception the problem is reduced, but not eliminated! My bedroom is WiFi-connected only due to wiring constraints and connecting from my laptop to my server via VNC or to copy files is very... very... slow. And really, try having a LAN party over wireless- I can run hundreds or thousands of network cables through a small room and connect everything I need for nearly any project or task inexpensively, and know that the network will be robust. Working with WiFi in anything other then a solo arrangement is a lesson in frustration.
TL;DR - Until security protocol and access control methods are more robust and available; until tools to design, implement, and test wireless networks are more plentiful and robust; and until bandwidth availability is not on par with but exceeds that of standard CAT5- wireless is but an adjunct, a convenient add-on to the main structure of a wired network in a business. ... err, not that I'm impassioned about it, or anything.
Precisely, which is why you'd get that response. If the company wanted you to use an iPad for your job they would either provide it or provide resources with which IT would support it. It's really clear that under typical circumstances that they won't provide the support unless they provide the equipment.
Plus, self entitled assholes like you make it a lot more difficult for the rest of us to get our work done.
Yes, but this thread was about people doing work. Not about people who parleyed social connections into dead-wood positions where they rake in large salaries to get in the way of the people who actually get shit done. (Or am I being cynical?)

how do your friends daughters and your wife not get headaches from:
tv signals
radio signals
cellular signals
gps signals
sunlight
cosmic rays/cbmr
garage door openers
remote controls
hell just sitting in front of a monitor or tv.
you are BOMBARDED with electromagnetic radiation all day every day. anecdotal story is fail.
Easy. You terminate your custom cable at the wall jack with your existing tools and only use the new connector for the last few feet to the device - and you purchase that cable.
