What does ghz mean when it comes to phones and which is better?

Question

whats it mean? and is it lan or land lines?

Answer 1

One of the best phones you can buy right now is the Panasonic DECT 6.0...!

Remember, a bigger MHz is not necessarily better.....we think here in the US that everything bigger (in numbers) is better!

well not so with MHz....actually the 2.4MHz has a further range then a 5.8 MHz...!

but security is the best with DECT.6.0 with build in firewall/router...!

900MHz is the worst!!! everyone should get rid of these phones!!

DECT is digital enhanced cordless telecommunications

FHSS is frequency hopping spread spectrum.

DECT phones are 1.9GHz phones

FHSS is a type of encryption, and channel changing function/feature available in different frequency range phones...

FHSS has replaced DSS (digital spread spectrum) as the latest security feature for cordless phones...

WiFi operates within the 2.4Ghz range, so a 2.4Ghz phone is a poor choice, but if this is the type of phone that you currently have, you may eliminate or reduce the chances of interference by changing the channel on the ROUTER, as the phone changes channels on its own, and there is no manual setting to change the phones channel...

The 5.8 MHz phone will provide you better chances at eliminating the interference... however at the possible cost of range, as the lower the frequency the further the range...

The BEST choice for cordless phone for range, and lack of interference is a DECT phone.. the 1.9GHz range is a licensed radio frequency for the exclusive use of cordless phones, unlike any other cordless phone frequency (900MHz, 2.4Ghz, 5.8GHz.) and as it is lower in frequency (aside from 900 MHz) it operates with the furthest distance then any cordless phone. (all cordless phones operate at further ranges then 900 MHz phones, because they have a higher transmitting power, and also 900MHz is a very active radio frequency..)

Answer 2

it is t he frequncie the phone overates on 5mgz or higher is the best, the higher the number the better your receotion on the phone

Answer 3

Ghz is giga hertz, MHz is mega hertz and Hz is Hertz. Giga higher then Mega Hertz then Hertz is the lowest. Cordless phones come in 900 MHz, 2.4 GHz and 5.8 GHz. In cordless phones, it is the radio frequency that the base and handset communicate by. It involves what they call wavelength, or the size of the signal. Contrary to previous answers, it is just the opposite.  The higher the frequency the greater the range for any given power as the size of the signal is smaller and it is NOT disapated easily.

Take a comparison of the Citizens Band radio at 27 MHz and the Family Radio at 460 MHz. CB output of 4 watts might get you 1 to 2 miles. (disregarding squelch settings) A FRS (family radio service) radio gets you 1 to 2 miles.. BUT IT IS ONLY 1/2 WATT OF POWER. However it is at 460 MHz, not a LOW 27 MHz.

So a 5.8 GHz phone will give you farther, and clearer signal as the small wavelength is not bothered by outside forces.

2.4 GHz was ok untill everyone started setting up WIFI networks. The wireless routers also work on 2.4 range so there is interference.

1.9 is also allocated for use by Sprint in their "cell phone service" so it is not restricted just to cordless phones.

The 900 MHz phones of the past were within range of "police scanners" or radio scanners. These scanners had a receiving range of 25 MHz to 1.3 GHz. Thus led to "spread spectrum" and "digital" (encrypted) use between the handset and base. Newer scanners today have these frequencies blocked out. so they cannot be received. (along with standard government and cell phone frequencies.)

Answer 4

GHz means gigahertz - an operating frequency of billions of cycles per second (a 1.9 GHz wireless phone operates at a radio frequency transmission signal at 1.9 billion cycles per second).

Other types of phones operate at 900 MHz (900 megahertz, or an operating frequency of 900 million cycles per second) and 5.8 GHz.

The frequency of operation is different in different phone models, because those are the frequency channels allotted by the FCC for wireless phone communications. When the lower frequency (900 MHz) got saturated, they opened up 1.9 GHz and then 5.8 GHz.

The lower frequency phones generally work better without line-of-sight communication to the base station. But, the higher frequency models are generally a bit more sophisticated.

Answer 5

All cordless phones run at a very low power. (around 100 mw.) There is a lot of 'hype' in the cordless phone world. I ran tests with 900, 2.4 Ghz. and 5.8 Ghz. I found little to NO difference in range. In fact the 5.8 Ghz. had the worst range. (Higher the frequency, the less range.) Spread spectrum had no difference. That just frequency 'hops' the digital signal. I have had NO interference problems with ANY cordless phone. That includes 900, 2.4, and 5.8. DECT is another joke, the only plus is the frequency is a bit lower than 2.4 Ghz. (1900 Mhz.) possibly giving you a few more feet distance. The biggest problem with any cordless phone is objects between the phone and base. From a window, you might get better range. If you live in a building with a lot of walls, wires and metal, your range is greatly decreased. (If you read fine print, even most 5.8 Ghz. phones use 2.4 Ghz. for the BASE UNIT.!!) Just get one you like. Very little difference.
