Anonymous peer reviews sound like a great idea, so many want our kids to take standardize testing and fire the teacher that has the worst kids. My wife who teaches second grade is considered a "Highly Qualified Teacher" by the state of Arizona. She is given the worst readers at her school. They are split up between 3 categories "above grade level", "at grade level" and "below grade level". It is the goal to get them to grade level or greatly improve there skills by working with the child's skill set depending on their ability. Unfortunately her efforts are not always successful. If she was paired up with the exceeding or average students she would look better on paper but currently there is limited success with the lowest of the low. Still she measures her success one child at a time, testing could not measure this unless of course that child advances to one of the other two groups. My wife teaches because we can afford it. 33,000 per year with a masters degree and as a reading specialist isn't much, it hurt worse this year when she had to take a 6% cut in pay since the state has cut the education budget. Oh and the summers off, that would be about 9 weeks, 2 of which are spent,,,,, well going to school to be a better teacher.
Try Arizona, you will make about 35,000 per year with a masters degree for the first five years. (minus the 10% cut they will get next September due to budget shortfalls with Arizona.) Summer jobs are few and far between, nobody wants to hire a person for 2 and half months.
McDonald's does pay about $30,000 to be a manager for less hour's, teachers don't work a 7 hour day if they want to succeed.
When my wife said she was going to quit being an Oracle DBA and announced she was going to start teaching, I thought she was a nut. She make's a fraction of the pay, works nights & weekends and gets zero respect from parents.
When you teach, your success is measured with "ohhs and ahhs" from the kids, not the pay.
I Worked for Dave and crew at the last Superbowl in Phoenix. I was the wireless vendor that the Superbowl hired for the outdoor wireless. Everything that Controlio says is true. He is a great guy, they have there act together and he is a good man to work for. He led the entire site from weeks before to the week after. Three weeks later I received a hand written thank you card and a gift from Dave. In a world of thankless days, I have kept the thank you note on my desk from Dave Port, He seems to have this game plan down. I guarantee he did not watch any of the game tonight, he was running the show. Next week he will sleep!!
I have a ten meg connection at my house but I download files from a server that has a 1.5 MBPS T1. The server I download from or upload to may have 15-30 others doing the same thing. I have no idea if Cox Cable is keeping me from my 10 megs because I have a Ferrari that I am driving on a one lane road behind a street sweeper. The internet industry has based its model around T1's so what can we do other than boast we have a high speed connection and hope the others have it too. What are the chances the network path chosen by the routers are all large pipes.
When it comes to testing my connection, who is to say that my ISP does not have a high Quality Of Service applied to the most popular bandwidth testing sites, that would be good for business if QOS was enabled for those test sites.
By the way,,, I have my entire house wired with CAT6, gigabit switches and gigabit NIC cards so I can pummel the crap out of my 10 MBPS Cable modem, I am thinking about changing to fiber, your thoughts!!
Help me understand how to achieve the speeds of what 802.11N promises without gig ports on the access points. I have had several of my customers request future infrastructure for 802.11N for use in there facilities but they are miffed when I specify gig switches and cat6 cabling to the access points. These are sites with internal infrastructure so the added speed could benefit them if they need to hit a database fast, most of the time a good cisco or symbol 802.11B/G provides all of the speed that is needed for day to day business.
802.11N is just a fad to me I set up wireless networks in million square foot warehouses. I am more impressed in quality proven products. When 802.11N is supported by commercial wireless providers like Proxim, Symbol and Cisco (not linksys,, Cisco) I will start looking at it, but why waste your time until then.
I write this post on an 802.11G access point (54 megs half duplex). After encryption I am hitting my cable modem at a blazing speed of about 22 megs full duplex. I am funneled down hitting the world wide web at 1.4 mbps.
Backtrack, backtrack, backtrack, I was trying to make the point that few of the big boys can help the rural areas. It would have to be a local vendor with pockets deep enough make a investment that will need to recover there investment over time. I love wireless networking, I install wireless for a living (not wireless cell phones but point to point links, indoor, outdoor coverage plus security). The cost of tower techs who must work in teams of two, trucks and insurance really take the fun of a small township project because of the rates we must charge. It really has to be a jack of all trades running one of these types of businesses. It is too bad but the companies that are really hands on make the money and will be around for a while. The ones that are there to collect a check from the customers as fast as possible dont make it. You must have love for the game.
The parent article hits close to what could be the issue for some. Cable TV and DSL have limitations on infrastructure so they cannot reach rural communities. With the decline of federal telecom taxes the rural infrstructures that would normally benifit from federal subsidies will do what they can to get by. Meanwhile the urban area that perhaps have thousands of humans per sqaure mile will have better equipment and a smaller cost per users. Lets think of wireless, I could cover a square mile but why would Invest on a rural area where I could ony hit 50 users when I could hit 3000 per square mile in LA or 25,000 per square in NY.
I have installed Sat systems on Arizona Indian Reservations, the speed makes me want to get sick because its so slow, but the end users are excited because they may have a 56K modem or a fractional T1 running an entire school. The local TELCOs can charge what they want for a T1. Satalite systems could really explode if the cost per meg was to balance out a bit. The rural communities will never benifit from cable internet or DSL.
Lets face it, Todays internet is made for High Speed Internet subscribers. Try dial up for a vacation week and you will know what I mean.
I agree, continue school! Dont quit until you have a 4 year degree at a minimum. I am 43 and have been in "IT" since 1986. I make a good salary but I would enjoy teaching more. My wife has gone from IT to teaching and the security and personal rewards are tremendous. I have made the money I need to get my kid to college, it is time to work at something that is fun. "IT" is not it. I wish I had a 4 year instead of the 2 year degree I have so I can qualify for a more stressfull, one third paying job as a teacher. Its not the money but it is the kids like you that want to learn.
Not a bad idea to think when it will stablize. I like to see what the Two leaders in wireless are pushing for there wireless lines.
Cisco and Symbol Technologies are the industry leaders for indoor wireless right now. Cisco is in my areas of the network where there is carpet and Symbol is made for the factory floor (no frills, heavy duty). If you are trying to justify the use of 50-100 hand scanners for $1200.00 a peice so the fork lift drivers can scan products and manifest's before they are loaded on the trucks you better have a future for your infrastructure. 802.11B/G are stable, most industrial applications are built around this technology since it is inexpensive to deploy. 802.11A is not as standard but it works well when you want to keep the traffic on different access points, I only use 802.11A for our executives in the conference rooms because the cell size sucks and the signal drops within about 50 feet if you are good at your power settings and assosiation rates. Most Dell laptops have a trimode card, we have the 802.11A on our corporate VLAN and the 802.11B/G is on our industrial VLAN that only has two servers on it. (no email or web access).
Lets face it somebody is going to try and hack your wireless, make the building next door look more inviting.
The 802.11A propigation would drop in the next room but the 802.11G would carry on, keep in mind that with a full power Cisco AP and a full power Cisco card you can go about 90 feet and still achieve 54 MBPS (actually half duplex, more like 21 full with WEP). If you are using AP's that are not Cisco, Symbol or Proxim your signal is not going to penitrate all of the walls.
When I do a wireless network, if the user density is high I will use 802.11A since the radio is so weak, I can get less users per cell or AP. If I am seting up a network for maximum coverage I use 802.11B/G to get maximum propigation.
Use 802.11A in a Cube farm, 802.11B/G in a warehouse where it carrys far and only has to communicate with 5-10 scanners or laptops per AP.
Great Idea on 802.11A, but it is not as popular,,, but Dell installs the tri mode cards on many laptops but most everyone else has 802.11B/G.
I know that it is impossible for these two giants to work together but I would have two SSID's on the same access point and point Continentals traffic over a different VLAN and push it strait to Continentals wireless gateway. This is a pretty basic function on a Cisco Access Point and it would allow the two networks to co exist using one access point and would also respect the frequency plan that the Airport has set up for their pay per use system. I know it sucks to be him but there is a network tech in Boston dealing with a massive noise floor in the continental area and they have a customer that doesnt undersatand that this is a public spectrum. May the highest gain antenna win.
I work for a wireless company in Scottsdale, Our company does not work on residential networks because there is usually no budget to secure a network. The only choice is to make the network look less inviting than the three others on the street. A war driver running around will notice a network not broadcasting SSID but why play when there are 3 others that say LINKSYS, NETGEAR or TSUNAMI (these scottsdale residents can afford cisco in there houses). The point is that yes there is a consulting chance but when you deal with wireless for anyone remember this phrase. "If you cant see it, it must be the problem" There are so many residential customers that have loads of viruses and spyware running on there machines that wireless is to blame for all issues. If you try to consult the home user, you have too much time on your hands.
I am a user of Cisco, Symbol and proxim products, not much of the home stuff goes onto my network. I normally turn the power settings all of the way down and set the minimum speed of the associating device to 11 MBPS or 5.5 MBPS this would not let devices beyond the 5.5 meg cell associate. I also position the AP away from outside walls and windows so anybody sitting in the parking lot cannot associate at 2 MBPS and try to bust the WEP key. Lets face it there are many persons out there with more time on their hands than the rest of us.
I would hope the netgear and and linksys goodies have power settings because why would you want to blast the person next door with access to your network. There are WEP crack tools out there so if you are running WEP there is still ways to get in,,, even ciscos leap has been reported to have been cracked on slashdot yesterday and that was pretty secure.
This is good info to have, Keep in mind if you are trying to impliment wireless in a corporate environment, crappy range is a good thing. I have common problems with Cisco and Symbol AP's having such good range that too many users will pick up the signal in the cube farms of todays corporate america.
I try to place my AP's so that 25 users will access them from there desks or conference room. Some conference rooms that are very large I will place 2 or 3 AP's on different channels with the power turned all of the way down so it will balance the user load between the them.
Since there are only 3 non overlaping channels it is often a chore to design wireless in a room where the same channels dont overlap with each other. Poor range solves this problem. Think of how to put 5 AP's in a room with 3 channels, it can be done, poor range is the key.
We urge our users to use their wired connection and use their wireless when in meetings or on the road at other corporate offices.
AIX would run on them, in fact motorola used to manufacture powerpc boxes to compete with the RS6000's (Phoenix AZ). The high end boxes would look similer to the IBM 43P and the F50..... but the lower end goodies looked like a mac powerpc there marketing name was the Motorola PowerStack. Here is a link but I have never seen one run on NT. (I dont often see much run on NT)
