How do I choose the best frequency for my cordless phone?

Q. What is the difference between the frequencies?

A. the best a safest you can get right now is the DECT6.0....

What's the difference between 900 MHz, 2.4 GHz and 5.8 GHz phones?

Your average cordless phone is actually a radio transmitter/receiver that operates across various radio frequencies. The three currently used frequencies are 900 MHz, 2.4 GHz and 5.8 GHz. As you step up in frequency, you'll experience an increase in the signal clarity and the range your phone can reach from its base station. However, the actual range and sound quality of your phone can be affected by obstructions within your home and interference from other electronic devices. Here are some general guidelines for choosing one of the three frequencies:
900 MHz

Most manufacturers have begun to phase out 900 MHz phones with AT&T having phased them out completely. Phones operating on this frequency are fine for household use and reasonably priced, though the features offered with these phones are limited.
2.4 GHz

The majority of phones on the market today operate on the 2.4 GHz frequency. This higher frequency provides better performance and sound quality than 900 MHz models. With more models to choose from, you'll also find more available features, including integrated speakerphones and support for multiple handsets. One thing to keep in mind is that other electronic gadgets, from baby monitors to wireless networking gear, increasingly use the 2.4 GHz band and may cause interference. If you use these items in your home, consider purchasing a 5.8 GHz phone.
5.8 GHz

5.8 GHz phones offer the latest in cordless telephone technology with the best clarity, range and possibly security. The biggest advantage to a 5.8 GHz phone is that its frequency band is less trafficked than the 2.4 GHz band, resulting in less interference. The chips that generate the 5.8 GHz signal are more expensive to manufacture, so expect to pay a bit more.
Analog versus digital

You can find both analog and digital models within all three of the main frequencies (900 MHz, 2.4 GHz and 5.8 GHz).
Analog

Analog technology applies to a system of recording or transmitting sound. In an analog system, the changing energy in the sound is converted to energy variations in another medium, for example, magnetism in a tape.

Analog cordless phones are the most affordable and available option. You will experience adequate range and good voice quality. Drawbacks include poor security (anyone with a radio scanner will be able to listen in) and static when you move too far away from the base station.
Digital

Digital technology is also system of recording or transmitting sound. In digital systems, the changing energy in the sound is continually measured.


What is a good prank to pull at my party?
Q. I'm having a Sweet Sixteen party, and I want to pull a really good prank on my friends. Like, one that will get them really scared like on the show Scare Tactics. I'll have about five people in on it with me and the rest of the eight or so people at the party will not know. Give me any ideas, as long as it doesn't cost a bunch of money. Thanks!

A. preparation for prank,
1Tipe a ransom note.or do that cut out of newspaper thing and write i have (your name). if u ever want to see her again leave 100 dollars on (something in your yard). then ill return her.
disconnect your phone
2 hide a all black outfit,ninja style, in your yard. hide the ransom note too. put a baby moniter receiver there too.
3,put a baby monitor transmitter in room yull be in.
4 tell the peeps in on it to make sure everyone is scared,and have them say stuff like,what if shes dead or stuff to scare peeps.
also have them try to convince people its real.


prank ,
start after dark.

after prank,
email me and tell me how it went.


Why does WIFI lose quality and speed the longer you stay on?
Q. Seriously, I'm computer retarded and just wondering why it does that. It goes from 54mb/sec to 10 or less sometimes.

A. If you speed is dropping then it is nothing to do with how long you have been connected it must be down to another problem.

Generic advice for improving wif reception [you give no info on the router or what device you are connecting with]

To start with the basic rule is to position the wifi router as high and as centrally as possible in your house.

1] Try changing the broadcast channel from the wireless setup interface for your router/modem.You can normally access this by typing "http://192.168.0.1/" into your browsers search bar and then look for the wireless settings menu.
You don't say if your router can use the 5GHz frequency or just the 2.4GHz. The best channels in the 2.5GHz spectrum are 1,6, 11, or 13 as they have less overlap with the other channels.

There is a useful article here about how to get the best performance by selecting the best channel.: http://www.howtogeek.com/howto/21132/cha�

If you have an android smarthphone, or a friend does, then install the Wifi Analyzer app free from android market and use it to scan for the best channel and change your routers broadcast channel accordingly. This app will aslo show you all the wifi signals in range that your neighbours are using, so you can select a different channel to them, making a stronger signal for you. https://market.android.com/details?id=co�


2] You can use a tool like Nirsofts totally free WirelessNet View to look at all the local wireless signals that are within range and may be competing with your own router and interfering with reception. from here: http://www.nirsoft.net/utils/wireless_ne�

3] You can buy a Wi-Fi booster like D-Link 645 Smartbeam, here: http://www.amazon.co.uk/D-Link-DIR-645-W�
Devices such as these can actually boost the wifi signal by using multiple beams that bounce of the walls and are intelligently directed toward whatever device [smarhphone, laptop, tablet] you are using on wifi.

4] If your using the 2.4GHz frequency and not the 5GHz then other devices that use this frequency band can alsso interfere with your reception [eg baby monitors and microwave ovens use 2.4GHz]. Try and make sure that none of these devices are situated between your router and your wifi receiver eg laptop, tablet, smarthphone etc


Why is my internet so much slower on my laptop?
Q. I'm with virgin, both my computer & my laptop are connected to my via wireless connection. But my laptop gets but a small fraction of the speed my computer does.

Any ideas on how to sort this out?

A. I assume that although you say both the laptop and desktop use a wifi connection that they are not situated in the same place. It is likely that the signal strength will vary in different positions in your house. If the router supports the latest draft n wifi standards and so does the wifi adapter in your desktop then check that your laptops adapted supports 8011n too. If it only supports earlier wifi standards like 8011.g then this is much slower and the reason for the difference.

If the wifi chip in the laptop also supports the 8011n wifi standard then there are several things that can affect wifi signal and things you can do to try and improve things
