LTE Overview: LTE Solutions

Worldwide demand for mobile data services is primed for explosive growth, fueled by rapidly improving quality and availability. Across the spectrum, consumers are demanding more from mobile. They want expanded services, richer multimedia experiences, easier access and greater personalization.

The key applications for the next generation of mobile users include person-to-person communications, content delivery, social networking, business services and mobile commerce.

To deliver these applications with the quality of service that customers expect, mobile networks must achieve higher performance. The prerequisites are high-speed, broadband-like access via mobile devices, delivered anywhere and at any time.

LTE (Long Term Evolution) is the best technology for mobile broadband networks because it is faster, simpler, more efficient and more cost effective than other options. NEC is an industry leader in LTE. By increasing speed and expanding bandwidth, our LTE solution creates new services for end users and new opportunities for operators.

For network operators ready to embrace the future, the next logical step is LTE (Long Term Evolution). A worldwide technology standard adopted by 3GPP, LTE has the speed and performance to deliver a new generation of multimedia services at more than 100Mbps, while lowering costs for end-users and operators alike.

LTE enables delivery of compelling and profitable services based on emerging mobile technologies. It allows operators to differentiate themselves from competitors. The advantages of LTE result from highly efficient radio technology and a simplified all-IP network architecture featuring greater flexibility and scalability.
