Q. What is the difference between a phone that has 5.8 giga hertz and 6.0 giga hertz?
A. I think that you are asking in relation to cordless phones... In which case, there are NO 6.0Ghz cordless phones... there is however DECT 6.0 phones, which operate in the 1.9Ghz range...
When it comes to radio frequencies, the lower the frequency, the further the range, as long as all other factors remain the same. 900Mhz phones would in theory have the best range, however, they operate at lower transmitting power then other cordless phones.
From best (range, battery life, etc) to worse:
DECT 1.9Ghz - best range, least interference, unlicensed radio spectrum dedicated strictly for cordless telephones.
2.4 Ghz - next best range, however this unlicensed radio spectrum is crowded with wifi, wireless video cameras, and various other wireless consumer devices, and therefore subject to increased interference.
5.8Ghz - unlicensed radio spectrum, not as crowded as 2.4Ghz but also may contain other consumer electronics. range is limited compared to 2.4Ghz and DECT phones.
900Mhz - no security, can be listened in on any radio scanner ("police scanner") unless equipped with DSS. least range of all currently available cordless phones. Many consumer electronics such as baby monitors, and wireless intercom and doorbell systems, and garage door openers operate within this frequency range.
1st Gen cordless phones (aprox 48Mhz) - poorest range, no security, can be listened in on with a radio scanner, also shares unlicensed frequencies with baby monitors. Limited frequencies. No longer commercially available, however some (very few) of these phones are still in use.

Does a low signal strength make my connection worse in Modern Warfare 3 on PS3?
Q. I meant low signal strength from my router.
A. Yes. The lower the strength of the signal, the slower it will be.
To increase signal strength, you need to remove sources of EMI (electromagnetic interference) such as baby monitors, 2.4GHz phones, microwaves as well as possibly moving the router to a better spot to decrease dead zones in your coverage area. You can try moving the router closer to the PS3 if that's an option.
Other options include installing a bigger antenna, a directional antenna or adding a wireless access point.
And another way is to eliminate WiFi completely by using Powerline technology. You can use the electrical wires of your house to transmit data. You would need an adapter on each end, though.

Why is my bluetooth internet connection unstable?
Q. I'm using a laptop and a cellphone to connect through the internet with GPRS. When I use USB cable, the connection is 100% stable and fast. But when I use the bluetooth to connect the cellphone to the laptop, the connection speed drops to 10-20% of its optimal speed. Besides, it's so unstable that there's no data transfer at all sometimes (a lot of times actually!).
Please advise me what's possibly wrong with the bluetooth connection.

A. Aside from lousy or defective equipment, it could be interference.
Bluetooth uses the 2.4GHz band, which it shares with cordless phones, wifi, microwave ovens, wireless security cameras, baby monitors, you name it.
Then you have people with data-doubling wireless routers with in-line amplifiers that will stomp all over the spectrum.
If you're moving from place to place, city to city, and have the problem equally everywhere, then you can probably safely rule out wireless interference. You could also try disabling the wifi card in your laptop just for kicks, in case that could be creating interference locally.

do wireless landlines pick up yours or your neighbors phone conversation?
Q. i dont have unlimted minutes on my cell phone.my parents believe that if you have a wireless your neighbors could listen to the conversation know i cant talk on the phone while on the computer or go to my room im going to show my parents the anwsers please help convince them that a wireless land line is better
A. the first cordless phones operated around 48Mhz as well as baby monitors and the like...and were easy for people to listen in on your conversations.. it was not uncommon for a baby monitor to pick up your conversation, or for 2 cordless phones to hear each other....
the 900 Mhz phones solved some of those problems... but people with radio scanners (police scanners) could still listen in on your calls...
DSS technology stopped that... and many newer 900 Mhz phones come with DSS...
also most 2.4Ghz phones have DSS or FHSS, aside from that, most radio scanner equiptment only goes up to 1.3Ghz - however these phones may interfere with WiFi
5.8Ghz phones also normally come with DSS or FHSS... and again are outside the range of most radio scanners.... however, because they are a higher frequency the range is less...
DECT phones operate within the 1.9Ghz range, are immune to interference from other devices, and provide the best range, clarity, and security...
so the only way that a neighbor can listen in to your conversation with a cordless phone that you purchace today would be if you bought a 900Mhz phone that did not have DSS....
