Wireless TNT

Electronic dog fences today are getting better and better. Developing more useful features and creating patented new technology, dog containment systems have become more advanced and reliable. One of the hottest pet fencing today is the Petsafe Wireless Dog Fence . Wireless? Yes, you’ve read that right.

Just when we thought that personal computers, video game consoles, printers, smart phones, and laptops are the only stuffs working on Wi-Fi technology, IEEE 802.11 has found its way to improve dog containment fences.

The development of electronic dog fences has already made containment easier and better for our favourite pets. The Wireless Dog Fence is considered to be a major development on electronic pet products. Designed for small to medium dogs, this easy-to-install dog fence is the new convenient way to safeguard and train pets. It is not just a dog containment but also an effective training tool teaching pets to stay away from restricted areas determined by owners. Composed of a signal transmitter, a waterproof collar, and boundary flags, having no wires to bury will help owners avoid any hassles that buried wires may bring.

So how does it work? The transmitter sends a signal to the collar worn by the pet. The wi-fi collar transceiver offers more customized options than any other collar. The wireless dog fence from Petsafe covers a wider range than any other similar containment. Pet owners are given the freedom to choose among the 4 static settings or go for setting 5 which offers Progressive Correction. As the pet comes near the preset boundary, the collar emits a warning tone. If the dog insists to continue, a pre set correction will be given.

Thanks to new technology, pet owners can have the peace of mind that their pets are safely contained. These pet dog fences are tested and proven safe and effective for dogs. Pet manufactures will continue to innovate high-tech pet supplies. New technology will make pet ownership easier and convenient. It also helps us become more responsible pet owners looking after the safety of our pets.

What is a Wireless LAN Bridge
Wireless LAN bridge is the connection two wireless routers, which are connected through 802.11N/G/B protocols. Once connected the routers act as wireless bridge adapter for the local devices connected to their LAN ports.

Why Do I need Wireless LAN Bridge
Wireless LAN can be useful in many scenarios. If you want to setup a home network where there several devices which need to be connected to the Internet . If the device have only Ethernet ports then it needs to kept near the main wireless router. Alternatively you can use one wireless bridge adapter per device to connect the main wireless router. Instead of using several wireless bridge adapters you can get another wireless router and connect it to the main wireless router. The additional wireless router will provide several ports.

How to setup router as a wireless bridge
All wireless routers are not created equal. Most of the wireless routers do not support wireless network bridging. Most of the routers from major manufactures do not support wireless bridging. You will have to pickup routers which support DD-WRT or the routers which support Wireless Access Point mode. See Selecting Wireless Bridging Routers.
In order to connect the routers you need set main router which is connected to Internet as DHCP server. Setup the second router in Wireless Client. Program the SSID and Security key same as the first router. Once this is done correctly second router will find the first router.

There’s an ongoing debate over the effects of radio transmission waves emitted by wireless products and their effect upon people. Anecdotal evidence suggests that there is a strong link to the frequent use of cell phones and some very unpleasant health issues.

These concerns flow over to other radio devices too, and we, those that sell these items, are continually asked about the safety aspects of wireless headsets.

Well, are they safe to use all day, everyday?

Of course, the salesman’s answer is likely to be – yes! But absolutely, I do believe they are and would have no hesitation in wearing one myself (which I do), all day, everyday.

Plantronics claims that its CS50 wireless headset has an output of only 1.7 milliwatts, which is about 1/1000th of the output of most cell phones, and in nearly all countries, there are the relevant certification and other statutory requirements that have to be met before any items like these can be sold and connected.

Bluetooth models have an even lower output than DECT (Digital Enhanced Cordless Telecommunications) or 900 Mhz headsets.

I’ve never heard of any incidents or situations, where a wireless headset was implicated in anything connected with the same issues we hear about cell phones, i.e. cancers, etc. So, from my point of view I feel quite safe in using them, even in areas where there maybe several operating at the same time.

Perhaps some may suggest that they haven’t been in use long enough, to adequately gauge the level of threat, if indeed there is one. Anyway, I’m not concerned: I will not give mine up!

If you feel like doing your own research in this area, you could start by visiting the Plantronics website and downloading their white paper on the CS50.

On the other, non-technical side, there are the safety benefits that are reaped by not having wires. For a start you wont trip over or catch them on anything and I feel the ergonomics – where and how you sit at your desk while making phone calls may even be further improved by using a wireless.

This is because you don’t have the cable to think about at all – it’s not tugging or constraining you, so there’s no anxiety about whether you maybe stretching the cable too much. This consideration is important if you want to conserve your headset cables, as I’ve spoken about elsewhere regarding the care of cabled headsets.

There is also the advantage, however unlikely, during a lightning storm, or any other extreme electrical disturbance of not actually being connected to the telephone grid. You’re not liable to be used by Mother Nature as a conductor!

About the only thing that is not safer is your bank balance, as dependant upon the country where you live, lashing out and buying a wireless headset is going to pinch your hip pocket nerve. But, if you’re serious about it and understand the benefits, you won’t regret the purchase.

You could take an antenna for every desktop computer (in laptops, it comes with 1 built in) and simply have one router to send the wireless signal to all of your computers immediately. That means you do not have to worry on extensive cords and wires all over your office or house.

In particular, a wireless router antenna is used to get radio waves, which are produced by the router, and converts them back to electric pulses, which the PC could translate into data.

Types of Wireless Router Antennas

Basics

There are 2 types of this type of antenna. The first type the omni-directional antenna. This could boost signal a bit higher on all directions. This would be great if you are either setting up a business where in you provide free wifi or you just want to set up the router in the middle of your office or house. You can freely utilize your wireless devices all through your home. The second type of antenna is called the directional antenna. This antenna is used to broadcast a very strong signal in a direction.

Assuming you wanted to set up a business and you only utilize wireless devices on a particular side of the building. Since omni-directional antennas are not as powerful like the directional antennas (the reason for this is because they have to distribute the signal equally in all directions), you can simply set up a directional antenna anywhere in your house and point it in that direction.

Range Extender

A range extender is a directional antenna. The advantage of this type of antenna from that of the first one mentioned is that it could be applied to both omni directional and directional antennas. This antenna as well operates with the antenna that you already have.

The way it works is just like a mirror. You just have to plug in your router like the usual way of setting it up. However, this time, the signal it produces would bounce-off and the range extender shoots it back out on a higher frequency.

Say for instance you have a restaurant and you don’t only want to offer your customers a free wifi access, but you as well want to offer the entire surrounding of your restaurant a free wifi (for whatever reason). You could easily do that because the range extender could generally pickup signals up to 1 to 3 miles.

Yesterday, I received the PSP game machine I had ordered from a online store . I love game, it is a part of my life, it makes me relax and feel good so I always take it wherever I go. But the problem is I cant connect PSP to the network when there is not a hotspot nearby, I asked my friends and searched the answer on the Internet, then I found a portable device which called Huawei E583C 3G Router. Its a wireless 3G router which can provide hotspot with a Sim card (cell phone card) anywhere. And its very easy-to-use, no complicated settings. If you have the same problem, just follow these steps.
How to connect PSP to 3G network with a 3G router?

Before the setting, make sure the PSP and HUAWEI e583c 3G Router are started:

Turn on the PSP WLAN switch.

Select Settings > Network Settings.

Select Infrastructure Mode to connect your local Wi-Fi access point.

Select New Connection to specify a mnemonic connection name (such as MyE5).

Select Scan to detect all networks within range. The access point list is displayed.

Select the SSIDthe same way as you did for the E5. Then press the button of your game machine consecutively to confirm the SSID and to input the Wi-Fi key.

SSID: The Wi-Fi name of the E5.

WEP: The Wi-Fi key of the E5.

The default SSID and key label is affixed to the E5.

Press the button of your game machine to continue, and then press the X button to save the settings.

Select Test Connection to check the connection. If the test succeeds, you are online successfully.

Finish. Go to Internet Browser.

Sometimes the connection may disconnect automatically, you need to re-connect it manually. It mainly due to the network status is not stable, none of the business of the devices. As I know and based on my experience, huawei E583C 3G Router is one of the popular wireless 3G router device and the quality is good and trustful. Any guys who love games and have the device that needs Wi-Fi to get internet access could take this one as the good partner of your game machine. I believe E583C 3G Router would give you fantastic experience of game enjoying.
