Today the Wi-Fi Alliance has launched Wi-Fi Direct. Wi-Fi Direct allows devices to connect directly to each other without the need for an existing network. The devices will basically function like a P2P network between each other.
The Wi-Fi Direct functionality will be available from vendors like Cisco, Apple, and Intel starting today. The first cards that have made it through the certification are as follows:
- Atheros XSPAN® Dual-band 802.11n PCIe Mini Card (AR928x)
- Broadcom BCM43224 Dual-Band 802.11n 2×2 MIMO PCIe Half Mini Card
- Intel® Centrino® Advanced-N 6200
- Ralink MIMObility 802.11n 2×2 PCIe Half Mini Card
- Realtek RTL8192CE-VA4 HM92C00 PCIe mini card
Wi-Fi direct supports WPA2 security unlike the traditional WEP provided on an Ad-hoc network. An Ad-hoc network was traditionally used to accomplish the tasks that are available simultaneously with Wi-Fi direct between your access point and device.
These Wi-Fi Direct devices are supposed to be able to connect to your access point and another device simultaneously. This functionality can be very helpful but can it also open up a security hole in your network?
With this new technology and the same with the original Wi-Fi technology you are susceptible to a man in the middle attack. A man in the middle attack is where someone can grab your SSID and broadcast it at a higher signal strength or power to force your computer to connect to them instead of what they were supposed to. Thus when the computer is forced to connect the attacker can intercept all of the traffic on the network without the user even noticing.
I brought this up because with Wi-Fi direct you are able to connect simultaneously to both your network and a P2P device or Wi-Fi Direct. So if someone attacked your Wi-Fi Direct connection, couldn’t they then tunnel into your existing network through that connection that they have created? Correct me if I am wrong but I think this is possible. Although the technology is a great leap forward I feel that I still need to make people aware of the inherent security issues that exist in Wi-Fi technology.read more
Sprint has just announced that the Galaxy Tab will be available on November 14th for $399.99 and is available for preorder today. The price is actually $100 lower than AT&T’s price for their Tab. However the lower price don’t forget about the data plans.
If you purchase the Galaxy Tab from Sprint to you will have to sign a 2-year service agreement with one of 2 data plans. The first with a limit of 2GB a month for $29.99 and a second with a limit of 5GB for $59.99 both plans have unlimited messaging.
Both of those data plans are quite expensive for the very low data limits they have. Imagine if you were to go over the data limit and were charged overages. If the carriers don’t find much more reasonable data prices for the tab it will not appeal to the general consumer.read more
To help new AWS customers get started in the cloud, AWS is introducing a new free usage tier. Beginning November 1, new AWS customers will be able to run a free Amazon EC2 Micro Instance for a year, while also leveraging a new free usage tier for Amazon S3, Amazon Elastic Block Store, Amazon Elastic Load Balancing, and AWS data transfer. AWS’s free usage tier can be used for anything you want to run in the cloud: launch new applications, test existing applications in the cloud, or simply gain hands-on experience with AWS.
With all of the new dazzle that the new MacBook Air offers, it comes without Adobe Flash preloaded. Apple and Adobe have been head to head recently because Flash is not on iOS devices. Maybe it was a fluke but or a slap in the face for Adobe but its definitely not included on the MacBook Air as we see so far.read more
Today at the Back to the Mac event, Steve Jobs announced an all new redesigned Macbook Air. The new MacBook air is governed by the idea of combining the iPad and the Macbook. Apple wants to increase the battery life and portability, they want to create the next generation of laptop.
2 different sizes of MacBook Air a 13-inch version and a 11.6-inch version. Both MacBook Air’s have a 30 day standby time and the 13-inch providing 7 hours of Wifi use on battery while the 11.6 version providing 5 hours of battery time.read more
