5G mobile networks will address the massive growth in mobile data traffic and connected devices. 5G technologies include using higher frequency spectrum like mmWave bands, ultra dense small cell networks, and new radio access technologies. This will allow 5G to provide significantly higher data rates through techniques like massive MIMO and advanced beamforming. 5G will also target requirements for low latency connectivity in areas like vehicle-to-everything communication and industrial IoT. The evolution of 5G is expected to start within existing LTE networks and expand to new radio technologies operating at frequencies above 30GHz.
Future Technologies and Testing for Fixed Mobile Convergence,SAE and LTE in C...Going LTE
This white paper discusses future technologies for fixed-mobile convergence including LTE and SAE. It defines fixed-mobile convergence as providing consistent services via any fixed or mobile access point. The paper describes the motivation for convergence including mobility and consistent services. It outlines the LTE/SAE introduction and technologies including the evolved packet core and all-IP architecture. Key aspects of LTE such as physical layer channels and protocols are also summarized. The purpose is to support an integrated network through the IP Multimedia Subsystem for high-speed mobile experiences comparable to fixed broadband.
LTE-Advanced improves upon LTE technology to meet the requirements for ITU's IMT-Advanced specification. This document summarizes the key technology components of LTE-Advanced, including band aggregation, enhanced multiple-input multiple-output antenna techniques, improved uplink transmission, coordinated multipoint transmission and reception, and the use of relay stations. LTE-Advanced aims to provide peak data rates of 1 Gbps downstream and 500 Mbps upstream, reduced latency, increased spectrum efficiency, and high throughput for cell edge users.
LTE is the next generation network beyond 3G that will provide significantly higher throughput and lower latency compared to 3G. It will use an all-IP architecture and OFDM and MIMO technologies to improve spectral efficiency and capacity. LTE aims to deliver 3-5 times greater capacity than advanced 3G networks, lower the cost per bit, and improve the quality of experience for users through reduced latency of around 20ms compared to 120ms for typical 3G networks. Mobile network operators have a unique opportunity to evolve their networks to LTE to capitalize on increasing demand for wireless broadband and further grow their market share.
This document discusses how LTE subscribers will behave differently than 3G subscribers and outlines requirements for an evolved Subscriber Data Management (eSDM) solution. Key points include:
1) LTE subscribers will use multiple devices and expect service ubiquity across devices and networks.
2) An eSDM solution is needed to consolidate subscriber information across access networks and domains to provide a personalized experience.
3) The solution must be highly scalable, reliable, and flexible to support new applications and services utilizing the large LTE network pipes.
LTE is being developed to address challenges in the mobile market including increasing mobile data usage and consumer demand for broadband speeds. LTE will provide significantly higher data rates and network capacity compared to 3G technologies. This will enable new applications like HD video streaming and improve the user experience. LTE also offers a lower cost per bit which can help operators offer affordable flat rate data plans while maintaining profitability. Seamless handovers between LTE and other networks will provide continuous connectivity and allow content to be accessed across multiple devices.

Spectrum Analysis for Future LTE DeploymentsGoing LTE
LTE promises high speed broadband and low latency services. Future spectrum needs for LTE are estimated to be between 500 MHz and 1 GHz by 2020. This document analyzes potential spectrum bands for LTE deployment, including refarmed GSM 900 MHz spectrum and newly auctioned bands such as 700 MHz and 2.5-2.6 GHz. Identifying and utilizing new spectrum allocations, as well as opportunites to refarm existing bands, will enable global LTE deployment and roaming.
Upgrade Strategies for Mass Market Mobile BroadbandGoing LTE
The document discusses upgrade strategies for mass market mobile broadband as wireless data demand explodes. It finds that the combination of widespread 3.5G networks, flat data rates, and internet-enabled phones will lead to spectrum exhaustion by 2010. While upgrades to 3.5G like HSPA+ can provide some relief, the economic advantages of LTE's high capacity through technologies like OFDMA and MIMO mean it is better suited to deliver affordable broadband at scale. Operators choosing an early deployment of LTE can gain a competitive advantage over investing in interim upgrades and may need fewer cell sites to meet future demand growth.
LTE is a 4G mobile broadband standard that aims to succeed 3G technologies like GSM/UMTS. It provides wireless broadband services using radio signals and allows for uplink speeds up to 50 Mbps and downlink speeds up to 100 Mbps with 20 MHz bandwidth. While deployment won't be widespread until 2012, LTE reduces latency to 10 milliseconds between user equipment and base stations. Users will need an LTE modem in a format like USB, ExpressCard or embedded in devices to access the LTE network on phones, PDAs and laptops.
