The Network of the Future
However, virtualizing large-scale telecom systems increases the complexity of service applications because of the increase in the number of functions to be realized. NTT, Alcatel-Lucent Japan, and Fujitsu solve this problem by developing server architecture as a platform of telecom networks with reliability, scalability, and management that network systems require.
LTE-X
LTE wireless technology provides unprecedented network bandwidth, latency and capacity and, as such, can be leveraged in exciting new ways. Here is a look at the cutting edge of LTE and how it can serve your needs in ways you might not have expected. What is LTE-X you might ask? It’s an overarching term ecompassing multiple, evolving flavors of LTE wireless technology.
LTE Advanced (LTE-A): in a word--super fast mobile broadband. South Korea was the first country to see LTE-A widely deployed, but other regions are slowly catching up. Is your network equipment up to snuff?
SK Telecom is busy building 2.1Ghz base stations to support its LTE-Advanced service in Korea. SK Telecom’s mobile network is one of the most advanced in the world and aggregates three bands to deliver 300Mbps speeds to customers.
LG Uplus, a leading mobile service provider in South Korea, and Huawei have announced that they will take the lead in using WDM/OTN technology for common public radio interface (CPRI) backhaul on LG Uplus's LTE-A network, marking a breakthrough in the field of LTE-A backhaul technology. The CPRI-over-WDM/OTN solution enables pooled baseband processing for distributed base stations, saving fiber resources and improving network reliability. The solution is a typical application of the "WDM/OTN-to-the-edge" idea in LTE backhaul scenarios.
"With the development of mobile broadband, high-speed WDM transport is no longer confined to the backbone. It has been extended to the metro core, and will be applied to the metro edge in the LTE-A era. LG Uplus and Huawei's innovation in LTE-A backhaul is a meaningful practice of WDM/OTN-to-the-edge," said Jack Wang, President of the Huawei transmission network product line.
LTE Broadcast (LTE-B): LTE-B technology allows content to be broadcast to an unlimited number of users through a single stream of data, freeing up network capacity for general use when launched commercially.
Possible future uses of the broadcast technology, some of which will be tested tonight, include people listening to live commentary, getting real time match statistics and being able to watch replays and game highlights on their smartphone or tablet.
Telstra recently trialed LTE-B during a soccer match. Mike Wright, Executive Director Networks, said the trial follows successful lab demonstrations and would be one of the first live event LTE-B trials in the world, marking a significant step in developing the technology for commercial use.
“When a large number of people gather in one place we often see a huge spike in the demand for data, which can stretch the capabilities of our network and affect our customers’ experience. This is particularly evident during sporting events with a lot of our customers looking to enhance the live event by accessing commentary or stats online,” said Mr. Wright.
“LTE-B offers us the ability to deliver content more effectively and provide all users the same high quality service using one single stream of data. This streamlined process frees up the rest of the network to carry other data, voice and text messages," Wright added.
VoLTE: Voice over LTE: The adored catch phrase "can you hear me now?" might be replaced with "can you hear me clearly?" If you're calling on VoLTE, both are probably true as this technology dramatically improves the call quality--when it works. There are challenges to getting VoLTE up and running, as the long delay demonstrates, and this is one of the reasons mobile operators like Verizon in the US market are now beginning to contemplate the retirement of their legacy CDMA networks.
