In my time in IT I have worked with a number of wireless devices for the consumer and for businesses. These have ranged everywhere from simple $40 products that are only meant to get you online (not fast, but online) to multi-component wireless systems costing thousands of dollars. All of these still use the same basic technology to get you connected and to pass traffic between your device and the internet. At their heart is going to be a wireless radio, but this does not mean that all wireless products are the same; quite the opposite in fact. There is a clear line between wireless for the average home and wireless for the average business. The factors are mostly in the software used and the features that you have at your disposal, but you also will often have more advanced hardware under the hood as well. Today we will be taking a look at standalone wireless access point that is aimed at the business market (although there are many things that consumers will like about as well). This is the NETGEAR WNDAP360 ProSafe Dual Band Wireless Access Point; let’s see if worth the $290 it will cost to put one of these in your office.

Wireless networking is one of those things that we all have come to rely on. We tend to expect to be able to connect just about anywhere now. I mean, even McDonalds has wireless now so why shouldn’t we? But what do you do when you come across one of those places that either does not have it, has poor quality (like many hotels) or you are just concerned about your security when on those open networks? Well there are a few companies that have a solution to this and we are going to take a look at one from EDIMAX today. It is one of the world’s smallest 802.11n wireless routers the EDIMAX BR-6258n.

 
 
The launch of the 450Mbps segment of the 802.11n specification was sort of backwards. We saw some of the first routers last year in the September – October time frame. Then at CES we got our first glimpse of one of the new 450Mbps wireless adapters. This was the TRENDNet TEW-687GA that we just finished testing. But we are not going to stop there as we have another 450Mbps adapter from TRENDNet in the lab. This one is more PC specific and connects over USB 2.0. You lose the universal appeal that the 687GA had but gain more on portability. So let’s introduce the TRENDNet TEW-684UB 450Mbps Dual Band USB wireless adapter.

One of the nice things about the latest generation of the 802.11 wireless specification (802.11n) is that there is a lot of headroom available in it before there is a need to move to a new generation. When 802.11n first hit the market it was limited to around 150Mbps. This was due to quite a few factors, most notable of these was the use of spatial streams (breaking the signal into separate streams and reassembling them in proper order at the far end. Once this was combined with MIMO (Multiple In Multiple Out) things really took off. Now we are hitting the upper edge of the 802.11n spectrum with the 450Mbps routers and adapters. This new line is getting up there and finally pushing the upper limits of what you can do with this latest revision of the 802.11 protocol. We have another one of TRENDNet’s 450Mbps wireless routers in the lab. This time it is the TEW-692GR a 450Mbps concurrent dual band gaming router with a price tag of around $135. So follow along as we find out if this is really worth your time and money.

Apple is famous for many things. They are famous for making the iPhone and iPad, they are famous for their never ending stream of patents for things that already exist and last but not least they are famous for making sure that you cannot use their mobile products without their approval. You see if you buy an iDevice your core file system is pretty much locked down. Now there are ways to get into the file system and move things around, but it can get messy and things do not always make the transition intact. The other side of this is that there is no way to add more storage to any of their products. It is not like an Android or Windows based tablet with an SD card slot or USB ports. So what can you do if you bought one of the 16GB non-3G iPads or if you only own the iPad touch? Kingston has an answer for you. Kingston has put their expertise in making flash drives to good use and attached a flash drive to a wireless controller that can also act as a wireless bridge. They are calling it the Wi-Drive and when you pair this up with the WiDrive app from the AppStore you might just have a relatively low cost answer to a lot of people’s needs. So follow along as we take a look at the $180 32GB Wi-Drive on a first generation iPad.

Sprint's EVO 3D from HTC hits our lab

Not too long ago I made a comment about the iPhone losing ground in the smart phone market. Not too long after that I started looking at the mobile phone market; not because I was trying to find some information about on smartphone purchases, but because I was interested in a new phone. The phone I was replacing is one of the most popular Android based phones on the Market. It was actually one that many people went to after the issues with the iPhone 4 (the grip of death). In fact that is how I ended up with my HTC EVO 4G from Sprint. The phone that caught my eye was another HTC phone. This was the HTC EVO 3D. This is a dual core high performance phone with a 3D Screen that does not need glasses to view.  So I went out and picked one up, let’s see if it was worth the money and time.

Suppose I have a picture that I have been given. This picture is not something that the owner wants shown to the world so they have given me a list of people that can see it. When someone wants to see it I ask them who they are and if their name is on the list I show it to them. However, this plan is not working out that well so the owner decides to add some requirements. Now when someone wants to see the picture they have to show ID. Still people are getting around that with fake IDs, so now the owner gives out a special code word that is unique to each person while still maintaining the requirement for ID. To make things even more secure I have a picture of each person and a copy of their ID. What I have described here is a very simple explanation of the way that some of the different levels of encryption work; from the very basic to much more complex routines. In this article we will be talking about encryption as it relates to wireless access points and we can tell you up front you will be surprised at how insecure some of them are.



We have another unboxing to tell you about. This one is in the networking arena. As you saw in our recent deliveries article we now have an Asus RT-N16 wireless router.  We have played with a few routers from Asus before and while they were not the fastest out there, they had some excellent features.  With that in mind let’s take a look at what we find inside the box and get a good look at the RT-N16 from Asus.

Ericsson sues Samsung

Another day, another patent law suit against Samsung. The company has been sued by Ericsson inU.S. Court. This time the lawsuit is about "key patents in mobile technologies." Looks like Samsung can’t stop getting into patent lawsuits, they already had to pay Apple $1 billion, will the same thing happen with Ericsson? [The $1 billion judgment in favor of Apple is not final and at least one patent from that trial is under review - Ed]

Researchers at several prestigious universities like MIT, the University of Porto in Portugal, Harvard, Caltech and the Technical University of Munich, have managed to increase the throughput of existing wireless networks by ten times. They have done it without adding base stations, expanding bandwidth range or boosting the power of the transmitter. Instead, they used a mathematical formula that eliminates the need to re-send lost packets, which are blamed for network congestion and the reduction of useful bandwidth.
