How Wireless N Dual Band Router Improves Your Network – Part 1

Part 1: The Cluttered Wireless 2.4GHz Band

Most of today’s wireless routers support 802.11g (Wireless-G) and many of them start to support 802.11n (Wireless-N) after the specification has been finalized in October, 2009. If you’ve bought a laptop or wireless router after 2009, chances are that they will support 802.11n and 802.11g.

Wireless-G and N can both utilize a common network frequency at 2.4GHz, it’s the same old 2.4GHz that have been used by earlier 802.11 and 802.11b networks, and also by most of the home & office wireless telephones and remote controls.

With so many devices using 2.4GHz in your house, and your neighbors’ surround you, 2.4Ghz networks are extremely cluttered with dozens maybe even hundreds of wireless devices.

To reduce interference to some degree, the 2.4Ghz network is divided up into 14 channels, with each one having its own frequency very close to 2.4GHz. They are 2.412, 2.417, 2.422, 2.427, 2.432, 2.437, 2.442, 2.447, 2.452, 2.457, 2.462, 2467, 2.472, 2.484 Ghz.

In North American only the first 11 channels are used, while in the rest of the world all the first 13, with Japan also using the last channel in their 802.11b standards.

Most 2.4GHz device can choose their channel at one of the 11 frequencies. The larger the difference in the frequency, the less interference the devices will encounter. Setting your device away from a cluttered channel might help a little back in 2003 when not so many Wireless G devices were around.

However, it doesn’t really help that much in 2010. By default, all wireless routers choose Channel 6, the one in the middle. If you and your neighbors did not change channel in your routers’ setting page, you are stuck in Channel 6 with a lot of other devices. Even if you are smart enough to change to Channel 1 or Channel 11, your laptop probably would still go head-and-shoulder with someone else’s devices in the same or a near-by channel.

Unless you live in a big house with a huge backyard, your network environment will be all very cluttered.

Does Wireless-N Help? The short answer is yes, as the new Wireless-N standards can utilize both 2.4GHz and 5.0GHz frequency bands.

Despite so, most routers that support Wireless-N still don’t support 5GHz, and they are using the same old, cluttered, 2.4GHz. Of course, in a perfectly clean environment, you will still benefit from Wireless-N’s wider range and faster data transfer rate. But if your router sits in a noisy 2.4GHz environment, it might not perform as well.

This is why so many users still don’t feel much of improvement after having upgraded to a Wireless-N router. Their gaming, P2P downloading, transferring files or streaming media are still slow or jerky, or they stop altogether from time to time.

Sure, the router could be overheating or have a flawed firmware, but more likely, you have a noisy, cluttered wireless environment that keeps interfering your wireless communications. It’s like a terrible traffic jam on a Friday afternoon, only every day for your router.

Fortunately, Wireless-N supports 5.0GHz, and it’s like a whole new open world, where your wireless devices can escape to.

In Part 2, we will discuss how Wireless N dual band router will help you cut through the interference and gives you much higher throughput and range.

So let’s have a break and I’ll see you in Part 2.

Tips To Choose Wireless Security Alarms

If you are looking for securing your home from burglars and unscrupulous persons, you should inevitably install wireless security alarms. These are systems to inform and notify police or other law enforcement agency against the encroachment to your territory. The wireless security alarms these days do not require a wired installation or any telephone or electricity lines to function. Therefore, these systems are easy to install and also do not have much operational faults. Thus you can see that security alarms are the best friends of every home owner today.

But, choosing a home security alarm is not an easy task to accomplish. You need to do a bit of research and investigation of the various factors before buying such a device for your home. These days you can buy burglar alarms from online companies. However, you need to be very careful while dealing with such companies as not all of these companies are genuine ones and may trick you to spend a lot of money on fake items. Therefore, the first step of buying appropriate wireless security alarms is to research on the company thoroughly. Before selecting an online provider of burglar alarms you should check its business credentials, licenses, certifications and registrations.

A reputed company would offer to inspect the area where you need to install an alarm. Thereby, you will be able to know about the appropriate type of wireless security alarms that you should buy. Even if a particular quote is agreeable for you, do not plunge into buying the devices before comparing it with other similar items across the Web. In recent news the Essex police have warned the citizens against cold callers for burglar alarms. This was following an incident where a man was cheated 3,000 as installation and monitoring costs without actually delivering the item.

Apart from the cost, you should also compare the features of the devices before buying. The best tip to buy wireless security alarms is that you should buy such devices that come along with motion detectors, window installation features, outdoor cameras and other sensors for enhanced functionalities. A well equipped wireless security system can go a long way in keeping thieves and mischievous persons away from your premises.

There is another benefit of installing wireless security alarms to your home. Your insurance company might offer you more amount of insurance coverage if you have such a security system installed. However, before installing such a system you should consult with your local law enforcement agency and your insurer to better understand the benefits of installation of such devices.

Wireless Control Systems

Today’s wireless locking systems also provide the same eligibility, protection and real-time capabilities as wired systems. For outdoor projects, like garages and pedestrian gate access, wireless control systems can bridge up to 1000 feet. This makes such systems suitable for garages, airports, utility companies, and military bases.

Due to the advancement of technology, it is now possible to use the internet almost everywhere. Among all of these wireless technologies are cellular phones, the use of SMS and Email with Bluetooth and Wi-Fi. Most people prefer wireless control systems because they are less invasive and thus reduce the need for carpentry, repainting and frequent maintenance, making them more suitable for hard-to-wire situations as well as new construction projects. Wireless access systems have been used all over the world for doorways protecting buildings and facilities ranging from schools, companies to government agencies. Wireless solutions also contain built in red alert system. They are supervised by a signal that when triggered will display a warning signal on the control alarm screen.

Wireless control systems had greatly helped to advance the companies in their dealings with customers, suppliers and employees. The flexibility of this technology greatly facilitates the organization of work by saving time and money. The technology market offers wireless control systems for industrial, automotive, commercial and military purposes. At first, these control system vendors offer purely mechanical solutions and they have been continuously introducing new technology to meet the increasing need for a tremendous variety of equipment.

Because various wireless devices differ in power requirements, sensors that are being powered by batteries should be monitored constantly for battery condition. Assuming the worst possible scenarios, the need for a battery replacement cycle can help avoid this situation, but this can also cause frequent battery changes thus increasing the costs and toxic wastes.

Wireless control systems are beneficial to consumers in many ways and this is the reason why more and more people are utilizing these systems.

Tehran this week secretly appealed to a number of computer security experts in West and East Europe with offers of handsome fees for consultations on ways to exorcize the Stuxnet worm spreading havoc through the computer networks and administrative software of its most important industrial complexes and military command centers. Iranian sources report Iran turned for outside help after local computer experts failed to remove the destructive virus.
None of the foreign experts has so far come forward because Tehran refuses to provide precise information on the sensitive centers and systems under attack and give the visiting specialists the locations where they would need to work. They were not told whether they would be called on to work outside Tehran or given access to affected sites to study how they function and how the malworm managed to disable them. Iran also refuses to give out data on the changes its engineers have made to imported SCADA (Supervisory Control and Data Acquisition) systems, mostly from Germany.
The Iranians are getting desperate. Not only have their own attempts to defeat the invading worm failed, but they made matters worse: The malworm became more aggressive and returned to the attack on parts of the systems damaged in the initial attack.
One expert said: "The Iranians have been forced to realize that they would be better off not ‘irritating’ the invader because it hits back with a bigger punch."
Looking beyond Iran’s predicament, he wondered whether the people responsible for planting Stuxnet in Iran – and apparently continuing to offload information from its sensitive systems – have the technology for stopping its rampage. "My impression," he said, "is that somebody outside Iran has partial control at least on its spread. Can this body stop malworm in its tracks or kill it? We don’t have that information at present, he said.
As it is, the Iranian officials who turned outside for help were described by another of the experts they approached as alarmed and frustrated. It has dawned on them that the trouble cannot be waved away overnight but is around for the long haul. Finding a credible specialist with the magic code for ridding them of the cyber enemy could take several months. After their own attempts to defeat Stuxnet backfired, all the Iranians can do now is to sit back and hope for the best, helpless to predict the worm’s next target and which other of their strategic industries will go down or be robbed of its secrets next.
While Tehran has given out several conflicting figures on the systems and networks struck by the malworm – 30,000 to 45,000 industrial units – the security experts are putting the figure much higher, in the region of millions. If this is true, then this cyber weapon attack on Iran would be the greatest ever.
That Israel has stopped the Iranian nuclear program is definitely so. In Natanzee, 3,000 centrifuges are idle in the result of the malwarm attack and others have been slowed down considerably. The question is of Israel has it stopped for a long time – or forever.

P.S. News like this makes me proud of being Israeli.

Hi
I need to find a wireless bridge to use in my house. My router is upstairs, and my computer + xbox is downstairs. Moving the router is not an option. Powerline adapters are not an option. Using a wireless card/similar for the xbox & PC are not an option. Basically, I can only use wireless bridging.

Am I right in saying that a wireless bridge can be
1) 2 pieces of hardware, 1 located at the router (& plugged in), 1 located anywhere else acting as a hub
or
2) 1 piece of hardware, that transforms the wifi signal into etherent cables (in basic terms)

If those 2 options are viable, #1 would offer the best connection, right?

If I’m completely wrong (or not, I don’t know), can you reccomend some wireless bridging products (preferably around the range of 50 pounds)

Thanks.

I’ve had someone dumping trash on my yard and harassing me, today was the last straw they dumped Puke in my car. I need an outdoor security camera that works at night so I can catch this person. police haven’t done anything.
