Long term everything

LTE stands for Long Term Evolution. The simple truth is that LTE is much more than just a new air interface, it is a complete ecosystem that will meet market demands for the next decade and beyond. In fact, LTE has the potential to reshape mobile communications, perhaps as much as GSM has changed the way people throughout the world stay in touch.

LTE will create a new broadband capability, leading to new services, innovative business models, and a leap from today’s information web to the “Internet of things”. Billions of devices will increasingly become connected to the Internet, from TVs to photo frames, games consoles to media players, coffee makers to car engines, digital cameras to navigation devices.

LTE will enable operators to truly differentiate in the marketplace with the highest possible quality of customer experience, and by achieving unprecedented efficiency in their operations.

Long term commitment to LTE

Nokia Siemens Networks has been a pioneer in developing a complete LTE solution and this commitment is reflected by the recent setting up of an LTE center of competence in Dallas.

“The center demonstrates our aim to locate key resources in close proximity to operators leading the roll-out of next generation technologies,” explains COO Mika Vehviläinen. “We have a global footprint in LTE, in North America, Japan, Asia-Pacific and Europe. Our LTE platform is winning a growing number of customers across the world.”

Long term experience

LTE will transform the customer experience, revolutionizing how users receive, consume and interact with information and content over mobile networks. They will have the same seamless experience across networks, regardless of the devices they are using or how they are connected.

New applications, such as machine-tomachine communications will be catalyzed. Social networking will become more convenient and more deeply embedded into consumer lives.

For operators, this all means a much broader base of opportunities to drive up revenue and increase profitability.

Long term efficiency

It is already clear that network traffic growth will far outstrip revenue growth, forcing operators to carry more data over their networks for less revenue per bit. The solution lies in LTE, which will fundamentally change the cost structure of networks, helping operators to achieve extreme efficiency.

LTE has higher spectral efficiency than HSPA, so more data can be squeezed into available spectrum. LTE uses a new type of modulation, Orthogonal Frequency Division Multiplexing (OFDM) that splits information into multiple narrowband subcarriers, allowing each to carry a portion of the information at a lower bit rate to achieve a very high average cell throughput.

LTE also makes full use of flat network architecture pioneered by Nokia Siemens Networks with its I-HSPA technology. This means fewer elements in the network, lowering capital and operational costs considerably.

Furthermore, LTE can re-use existing site infrastructure such as antennas, feeder cables, masts, hardware racks and power supply elements. For all these reasons, LTE will support much cheaper capacity upgrades than the deployment of new base stations based on existing technologies.

So, LTE addresses the need for efficiency and improved customer experience. It can carry the huge projected growth in data traffic, while bringing an ‘all-packet’ experience to the mobile world – one where both data and voice are carried across the same IP network and smoothly interwork with legacy networks.
