Battle of the Cordless Phone Frequencies: 2.4ghz vs. 5.8ghz vs. DECT 6.0

The dawn of the 21st Century has technology running at such a fast clip that even the most enthusiastic person can get tired of trying to keep up with it all. Regarding cordless phone technology, the recent arrival of DECT 6.0 not only begs the question of what it actually is, but also might provoke a debate over the pros and cons of different cordless phone frequencies. Let's take a closer look at the three dominant frequencies today and try to answer the question: if they could talk, what would they say?

2.4 gHz - Look, if it wasn't for me, there wouldn't even be a cordless phone revolution. Most cordless phone communication ran on my frequency. Sure, sure, my range wasn't quite a long as the old 900 mHz, but my vocal clarity was unmatched. I had some calls dropped and interference here and there, but hey, that's the tradeoff when using a higher frequency.

5.8 gHz - Mr. 2.4 gHz might have enabled the cordless phone revolution, but he's glossing over a few details. 2.4 gHz is a very popular frequency. Car alarms use it, not to mention baby monitors, microwave ovens, and even your favorite wireless computer network. Since they use the same frequency, all of these devices can interfere with good old 2.4 gHz. That's were I (5.8gHz) come in, less interference means better call quality. So, if any of you have ever got fed up over a dropped phone call, raise your hand. Guess what? You can blame it on Mr. Old School 2.4 Gee Zee himself.

DECT 6.0 - I truly don't mean to boast, but I am clearly the most advanced cordless phone technology. 2.4 and 5.8 gHz can't compete with me. First of all, my technology has already become the global standard, which means phones that use my frequency are much more portable than ones that don't. Secondly, my frequency band is relatively low, at 1.9 gHz. This enables a great calling range. Perhaps most importantly, I run on a dedicated frequency network that no other devices use, so my network is very resistant to interference. I also feature a layer of encryption that makes calls more secure and contributes to clearer voice quality. Oh, and I almost forgot to mention: my technology is considerably more efficient so that devices that use me consume less power, meaning you get longer lasting batteries.

In the debate between frequencies it seems that DECT 6.0 has the last word

This article was written by Paul Wise. Paul as we all most likely do, uses Cordless Telephones in his home. When it recently came time to upgrade, Paul researched different frequencies from 2.4ghz to DECT 6.0, different brand from Panasonic to the VTech Cordless Telephone. And now that the research is done, this article will hopefully help others in their search for the cordless phone that best fits their needs.

Thank you for clearing up the matter of which frequency is better. I currently own a panasonic cordless phone with 2.4 ghz and I have had no interference except that when I'm on the phone, the volume fades in and out (which I believe it's a problem with the phone because it may be refurbished). You have put my mind at peace so the only thing I have to do is "search for a cordless phone that best fits my needs"-Paul Wise
