For 4g CPE router, may we know what is the advantage of the VOLTE function?
Let us learn more details for VOLTE at first:
VOLTE-Voice over Long-Term Evolution is a standard high-speed wireless communication for mobile phones and data terminals, including the Internet of things devices and wearables. It is based on
the IP Multimedia Subsystem network, with specific profiles for control and media planes of voice
service on the LTE wireless broadband service defined by GSMA in PRD IR.92. This approach results in the voice service being delivered as data flows within the LTE data bearer, with no dependency on the circuit-switched voice network to be in the call path. VoLTE has up to three times more voice and data capacity than older 3G UMTS and up to six times more than 2G GSM. It uses less bandwidth because VoLTE’s packet headers are smaller than those of unoptimized VoIP/LTE, VOLTE is a voice call service based on the bai4G network. 4G, 3G, and 2G are all a network du standard Zhi, while volte is a technology based on the 4g network. Service must be implemented on the 4G network. The latter is a necessary condition for the realization of the former. VOLTE can realize high-definition audio and video calls under 4G networks, and at the same time realize high-speed Internet access, in this case, we integrated the VOLTE function together with a smart wi-fi router, that save the cost for telephone wire and it’s more convenient of installation.
WR11S 4g lte -CPE router is a 4G Indoor CPE router (Customer Premise Equipment) that provides superior wireless access performance and comprehensive routing capabilities to bring wireless broadband data and voice services to end-Users. It converts high-speed TDD/FDD signals to WiFi signals on the local area network (LAN). Wireless and wired devices, including mobile phones, laptops, tablets, and other smart devices, can access the LTE CPE router simultaneously, with features: 4G to WiFi of 4g LTE router, 4G to Lan of outdoor sim router, Support VOLTE of lte 4g sim router, DL 150Mbps of 4g CPE router, UL 50Mbps of 4g sim router, Support IPV4, IPV6 of 4g router, Maximum number of access 32+1 devices of 300 Mbps sim router, 2.4G, WI-FI Rate: 300Mbps of CPE 4g router, SMA detachable antenna of 4g wireless wi-fi router, can be connected to the outdoor wi-fi router 4G antenna, etc.
4g CPE router VoLTE function can bring users shorter connection waiting time, and higher quality, more natural voice call effects. Because VoLTE uses high-resolution codec technology, the quality of voice calls is improved by about 40%, and VoLTE brings users lower access delay (ie, the waiting time after dialing), which is 50% lower than in the 3G era, about 2 In the 2G era, the waiting time needs to be 6-7 seconds. In addition, the frequent dropped calls in the 2G and 3G era came to an end when VoLTE arrived, and the drop rate of VoLTE was close to zero.
