A TMN EBOOK: VOLTE - MOVING FROM DELAY TO DEPLOY
that we still have only a tiny number of operators who have deployed what is now a three year old standard for serving voice over IP in LTE networks. Why are we where we are? Certainly, sporadic or geographically patchy LTE coverage is one reason why we haven’t seen a quicker drive to VoLTE. While LTE coverage remains concentrated on specic urban markets, a fallback solution makes more sense than VoLTE, which provides its principal benets across areas of continuous or widespread LTE coverage. But operators surely do not plan to limit LTE to a few markets for any more than the near term, and certainly as more digital spectrum comes online in many markets we will see wider geographic coverage rolled out over the next 12-18 months. So while limited network rollout may be one short term explanation, it cannot explain the overall lack of strategic drive to VoLTE. Perhaps we must look for another reason. One place to look is that it takes a

A TMN EBOOK: VOLTE - MOVING FROM D
HD Voice is now available from 93 mobile operators in 66 countries, with operator launches growing 48% in 2013. There are also over 250 HD voice mobile phones announced on the market. VoLTE provides a way for operators to eciently oer the consumer’s growing demand for HD voice over a cost-ecient IP network. Let’s address the perceived lack of a business case for VoLTE, and by implication IMS. Implementing VoLTE on an IMS structure gives operators the chance of extending support to other communications services such as their own RCS services, or third party services, on a consolidated service and control architecture. Therefore the cost justication for investing in an IMS can be spread beyond core voice services to business models that take advantage of IP communications and web based services. Staying with the enhanced service opportunity, IMS end points also oer the potential for xed-mobile service integration - enabling operators without a
more simultaneous calls per MHz of spectrum. In addition, turning o 2G, and even 3G, towards refarming chunks of “freed” spectrum for LTE growth, gives the opportunity for operators to take advantage of the greater spectral eciencies of LTE as well as consolidate network operations. Acquiring new spectrum is a signicant investment for mobile operators – certainly much more than an investment in an IMS. A VoLTE deployment can reduce or defer new spectrum purchases, easily justifying an IMS investment for VoLTE.
