Long Term Evolution (3GPP LTE)
There is rapid growth in demand for cellular communication services fuelled by new applications such as mobile web-browsing, video downloading, on-line gaming, and social networking. This demand places huge pressure on network operators to adapt or migrate to new technologies to provide profitable services and high quality user experience.
3GPP LTE enables operators to operate new access networks that offer high spectral efficiency, high peak data rates, short round trip time as well as flexibility in frequency and bandwidth.
The main design goals behind LTE are higher user bit rates, lower delays, increased spectrum efficiency, reduced ,cost, and operational simplicity.
LTE will bring advantages for subscribers with new applications such as interactive TV and user-generated videos, and for operators with backward compatibility with legacy networks and simpler architecture. Among the main features of LTE, the utilization of orthogonal frequency division multiple access (OFDMA) as the radio access technology in the downlink and a pure packet-based .all-internet protocol (IP) architecture can be highlighted.
At Zeteon, we understand the challenges and difficulties faced by network operators and device manufacturers and their urgency to reach markets rapidly.
We help operators fully align behind a strong, strategic programme of change to build a long-term successful business. Our solutions and services help operators to migrate to LTE with minimum risk, roll out new services plans, lower the cost of operating and running the new systems, enter new markets, compete successfully in existing ones, and improve their overall performance. Our solutions to devices manufacturers help them shorten time-to-market and seize the opportunity LTE provides.
Why LTE
Throughput
- Very attractive and suitable for mobile broadband services which require higher data rate internet multimedia services
Improved and Simplified Architecture
- Eliminate redundant functionality, thus reducing the number of network elements.
Increased service provisioning
- Efficient end-user terminal power consumption
End-user's Terminal power consumption
- More services at lower cost with better user experience
Multimedia Broadcast Multicast
- Deliver services such as Mobile TV.
Reduced Latency
- Reduce round-trip delay for enhanced user experience.
Transition time
- Optimized control-plane latency. Efficeint state changes from camped state to active state, and dormant state to active state.
Enhanced Cell (eNB) Capacity
- Efficient user-plane capacity. Allows higher number of active users per cell.
Improved Spectrum Efficiency
- Increased bits/sec/Hz/site.
Enhanced Mobility - Terminal Speed
- Enables smooth operation of user equipment at high speeds.
Enhanced Mobility - Handover
- Maintains strong connectivity and smooth handover between cells always. Co-ordinated operation of core EPC
Increased Cell Site Coverage
- Increased range of cell coverage
Increased spectrum flexibility
- Scalable carrier bandwidths leading to improved throughput for end-user.
Self Configuration and Optimization
- Ability of equipment to self optimize for operation allowing operators to simplify and speed up deployment of new systems and services cost effectively
All IP backbone network
- Simplified and cost efficient network operation and deployment. Support IP based architecture. Total cost of ownership is low and operational costs are reduced.
Voice Call continuity
- Constant connectivity and seamless interaction with other systems like GSM, WCDMA etc.
MIMO Radio
- Supports multiple input multiple output providing increased transmission reliability and higher data transmission rates.
Multibeam Radio
- Reuse of frequency in different geographic location increasing overall system capacity.
