Comparing Wi-Fi and 3G or 4G for VoIP
The Benefits of Mobile VoIP
With the mobile VoIP industry thriving and making up one of the fastest growing segments of Internet traffic, the search is on to find the latest and the best technologies for transferring voice over the Internet. So far, nothing has beat out a traditional wired ethernet connection that can deliver fantastic speeds with merely a fraction of the latency that is involved with other wireless mediums. For this reason, all businesses migrating to VoIP will almost certainly desire to have a few VoIP landline phones. This not only closely replicates the traditional PSTN business model, it also delivers the best VoIP experience to date.
But the way people work has been changing dramatically over the past two decades or so. More and more individuals are working on the move and spending less time in the office. This shift in behavior has been accelerated by the growth of the Internet where people can communicate seamlessly via e-mail and conferencing no matter where they are. So far, the weakest link in the chain has been the telephone system which extends to mobile smart phones as well. The gradual introduction of VoIP into the wireless industry is taking away the last bastian of the plain old telephone system.
Finding the Best Medium
So the question we naturally have to ask is, what is the best technology for the wireless transfer of voice when combined with other Internet data? 3G and 4G have delivered powerful capabilities to smart phones and many individuals make use of them for VoIP communications. Unfortunately, there is no denying that these technologies suffer from more latency compared to a wired line.
An "in between" technology like Wi-Fi has actually shown the greatest promise for VoIP communications. It has a few important features that make it extremely attractive. To start off with, it has far less latency compared to 3G or 4G. In addition, it usually piggybacks off a regular wired connection and so does not have any meaningful bandwidth data caps. This combination of affordability, speed and reliability has made it the preferred medium for real-time Internet communications like VoIP.
There is every hope however that recent technological developments will dramatically increase the reliability and reduce the latency issues experienced by wireless data networks. Try and find a local SIP provider if you're thinking of switching from the PSTN network. If you live in Los Angeles for example, you can easily find a Los Angeles phone provider who will effectively service your need for VoIP communications.
