Voice over LTE is the communication of data linked with voice over a framework based on architecture which delivers appropriate IP multimedia services. Likewise, CSFB is a technology which is used in delivering short message service and voice services to devices enabled with LTE using circuit switched networks and GSM. On the other hand, SVLTE is a technical protocol and standard which is used to enable the usage of both voice and data networks together on the same device which by means of CDMA voice network and LTE data network. Whereas VOLGA is a technological approach which is used to achieve and deliver short message service as well as voice services alongside the LTE networks. In addition, SRVCC is a technical standard which is compulsorily required in the voice over LTE systems in order to allow packet domain calls on the LTE devices to transmit data through legacy circuit switched voice seamlessly. Such legacy circuit switched voice include CDMA 1x, GSM, and UMTS among others. Voice over LTE enables mobile network operators to provide with video, rich voice and efficient messaging services as a main offering. Voice over LTE permits the operators to engage data network in order to transfer voice services in moderately small sized packets. It also aids in increasing the overall efficiency of the spectrum and helps in reducing the maintenance and operational costs since only one network is used in voice over LTE.
Over the recent years, North America region has witnessed a widespread use and adoption of voice over LTE technologies. The U.S. voice over LTE market has witnessed significantly raped growth and is anticipated to continue to be a trendsetter in the global voice over LTE market. U.S. is expected to account for the major share in the North America voice over LTE market. On the other hand, emerging regions such as Asia-Pacific and LAMEA provide great potential chances to the established and establishing players in the global voice over LTE market. In addition, there is an increasing demand for voice over LTE systems especially from mobile companies for cloud UC (Unified Communications) and mobile solutions due to the faster speeds of their network. Furthermore, emerging economies of Middle East & Africa such as South Africa, GCC, Turkey etc. are some other crucial regions posing huge opportunities in the global voice over LTE market.
The global voice over LTE market can be bifurcated based on technology, end user, vertical and region. By technology, the global voice over LTE market can be divided into frequency division duplexing and time division duplexing. By end user, the global voice over LTE market can be segmented into smartphones, routers, dongles and others. Based on vertical, the global voice over LTE market can be bifurcated into circuit switched fallback, voice over IP multimedia sub system, and dual radio and simultaneous voice and LTE. Based on region, the global voice over LTE market can be divided into North America, Latin America, Europe, Middle East & Africa and Asia Pacific.
Major players operating in the global voice over LTE market are focusing on some key market policies such as mergers and acquisitions to keep grip in the constantly competitive market. Besides, they are focused on collaborating with local players to upsurge their market reach as well as reinforce their goodwill in the international market.
