802.11n throughput testing for Aruba AP 125

This morning we did some testing with a high-throughput wlan (see profile at the bottom of the page) using the Aruba 125. We setup the VennLab HT SSID for testing locally using 802.11n on the 5Ghz channels exclusively. We also enabled the 40Mhz wide channel in order to maximize throughput. Our testing yielded very good results as you can see below.

Our test setup consists of two MacBook Pro’s each running the iperf network utility (via MacPorts) with manually configured IP addresses. To establish a baseline, we first connected to RLAB, a network that is already established on our Aruba infrastructure. This is an 802.11g only isolated wlan that also allows client to client connectivity.


Connected to "RLAB" to get a baseline, the airport sees an RSSI of –49 which is typical of a very good connection and shows a transmit rate of 54 as would be expected. Here are the iperf stats using the default settings:

Macintosh-214:~ donwright$ iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 256 KByte (default)
------------------------------------------------------------
Tested first with RLAB (802.11g standard wlan)

[ ID] Interval Transfer Bandwidth
[ 4] 0.0-10.1 sec 8.45 MBytes 7.04 Mbits/sec

This seems low, but maybe that’s an iperf thing, which is kind of confusing since they use the capital M for megabits. If I take this at face value and move on, the increase with 802.11n does show up.

Connecting to my 802.11n "VennLab" shows a similar RSSI of 50, but with a Transmit Rate of 300, a 6X increase. This increase seems to be validated in the iperf tests below which average about a 6X jump to 50 Mbits/sec.

Previously, when we did the same test with equivalent Cisco AP. We didn't get that good reading. Cisco wireless still far behind Aruba technology. For me, Aruba Network still the best in wireless infrastructure. That is why, they conquer the world wide campus solutions for wireless networking. The security features offered by Aruba complied with US Military requirement.. (implemented for US Air Force).  Major telco companies also choose Aruba solution. There are still the best in the market.

How to increase your internet speed

A lot of my friends (including myself) keep complaining about their slow internet connection and slow downloading P2P session . It seems that Streamyx has throttled the bandwidth among the users. It may be because of heavy load of P2P connection by other users. As far as I know, every user should get their right for their port. Tmnet should not take this reason as their main point in reducing the speed.

There are 3 tricks in order to get internet much more faster than before:

1. The basic think you need to do is tweak your internet connection is by optimizing the TCP/IP setting. What is TCP/IP? Well, basically it is the suite of communication protocols used to connect host on the internet. If your TCP/IP settings are configured properly, you can achieve good speed with your broadband connection.

2. The second step is to optimize your internet browser. We will make the browser suit the type of your internet connection whether you use 512Kbps package or the 1 Mbps package. Both Mozilla Firefox and Internet Explorer can be optimized using this tweak.

3. The third step is to get avoid from traffic-shaping by applying some tweak for your favourite torrent client. This is very useful for P2P fan. for further info, the article on avoid traffic shaping might help you to make it happen

Well, we have just finished doing some tricks to optimize our internet connection using streamyx. Does your connection improve? If yes, then congratulation. If not, maybe we will have to wait for a few days hoping it will become stable later.

OLED Based Apple Notebook ready to be released soon ?

For all potential Apple`s buyers, you might wait jusr a while to have a new super aerodynamic-Notebook from Apple. Rumous has spreaded every where and it become a great marketing for Apple. By using Organic Light Emitting Diode (OLED) technology, the current hard-rock keyboard will be replaced by shiny-tiny-bright keyboard, together with highly interactive touch screen on the laptop.

The Best Thing About OLEDs?

So what’s the big whoop about OLEDs? Well, if you’re not familiar, the acronym stands for “organic light-emitting diode” technology, which some have been predicting for more than half a decade now will eventually displace LCD displays for computers and flat-panel televisions. The technology is also sometimes called light emitting polymer (LEP) or organic electro luminescence (OEL).

OLED technology could theoretically enable fabrication of display screens 1,000 times thinner than a human hair using organic light-emitting diodes that can be printed on a sheet of plastic and should be cheaper to manufacture — costing only an estimated 60 percent as much as LCDs to produce.

Other benefit of this technolgy is that , OLED could reduce up 60% off the manufacturing cost and we do hope the price of the new laptopn/notebook generation will be lesser. OLED is also believed to contribute much more less power consumption and again we will have longer spending time in playing laptop together with battery dependency.

But, the most important is that , could you imagine how interactive is your itune application when the start spacebar turn to stop function once we click to start. Moreover, this type of keyboard would really shine for media work, since applications like Photoshop, Logic, and Final Cut could be significantly simplified by displaying more information about (and on) each key . Apple has spent around US 500 Million on the OLED R & D together with LG to produce the OLED-based product.
