Everyone has heard whispers of it – that it’s going to revolutionize the way in which we communicate, along with a myriad of prophecies pertaining to the young and developing broadband standard. 4G LTE, an acronymn for Long Term Evolution, is rarely discussed though often alluded to when it comes to how it will impact Voice Over IP technology. More specifically, 4G LTE is bound to enrich mobile communications, and considering the powerful wave in BYOD, it really couldn’t come sooner, or at a better time – depending on how you look at things. The best perspective to take when analyzing the future of VoIP technology, is evaluating exactly what’s been powering mobile VoIP and how 4G LTE will positively improve upon that.
Connectivity Improvements & Future Development
VoIP technology currently faces a number of hindrances that are keeping it from growing to its fullest potential. Although there are many bandwidth optimization tools coming out, VoIP still has overhead requirements and demands that must be met. Connectivity limitations, commonly those offered by 3G and Wi-Fi – the most common network standards for mobile VoIP communications, simply won’t cut it in some circumstances. Not to be misunderstood, a solid, reliable Wi-Fi connection is more than ideal for VoIP communications. Although ideal, wireless internet capabilities are simply not always available – this is where the technology surely suffers, not to mention its users.
Pricing Adjustment & Efficiency
Currently VoIP is supported, as mentioned above, predominantly by 3G and Wi-Fi connections. Often, connections fluctuate through Wi-Fi, making it difficult to keep a consistent connection due to low range connectivity, while 3G can really run up data plans (which are unavailable through many providers if you haven’t been grandfathered in). Additionally, both 3G and Wi-Fi might not provide the speed to accommodate VoIP calls. Furthermore, 3G networks are starting to show their age, as providers seek ways to keep up with a more visually driven society, rather than a purely data-centric one. VoIP calling now features the ability to initiate a videoconference with the touch of a button, and it’s important that mobile devices be equipped for this, without any slowdown or skip-ups.
4G LTE is Designed with VoIP in Mind
Major companies behind LTE have been behind the technology in preparation for the growing adoption of VoIP. At this juncture, it’s clear that this trend is now upon us. 4G LTE only supports packet switching with its all-IP network, while other technologies are circuit switched. VoLTE, for instance, is designed based on the IP Multimedia Subsystem (IMS) totally eliminating dependency on legacy systems. For the most part, the development of these technologies have been exclusively geared towards mobile services, and withheld from OTT services. Providers continue to contend with OTTs, want to protect themselves from losing business to this market by keeping something exclusive and special up their sleeve.
Additionally, calls over 4G LTE boast Adaptive Multi-Rate Wideband, the mobile version of HD Voice. There is a long list of patents still pending and on the way, as 4G LTE is becoming more standardized for the future. New sign-ups and conversion of 3G subscribers with LTE is projected to speed up over the course of this year, with an anticipated 785 million LTE subscribers by 2017. As mobile VoIP adoption continues to grow, expect LTE to be behind it every step of the way from here on out.
