- Use a new band combination of FDD 1800, TDD 2300 MHz
- Take technology to the next level, set new benchmark to improve LTE coverage on current bands and equipment
- Exhibit optimal use of TDD, FDD spectrum to save costs for operators
Riyadh, Kingdom of Saudi Arabia - Nokia Networks and Saudi Telecom Company (STC), the largest and leading telecom operator in Saudi Arabia, announced today the successful demonstration of TDD-FDD Carrier Aggregation, the first with a commercial chipset in Middle East and Africa. The demonstration, carried out using a new band combination of FDD 1800 MHz and TDD 2300 MHz, sets a benchmark for operators to optimally use their scarce spectrum resources and significantly improve LTE mobile broadband network capacity, coverage and speed.
Carrier aggregation allows operators to create larger, virtual carrier bandwidths for services by combining separate spectrum bands, thus boosting capacity and speed as well as performance in the network.
Carrier aggregation benefits
- Combination of 1800 and 2300 MHz bands provide higher speed in larger areas
- High frequency bands have limited uplink coverage, but operators can significantly extend TDD coverage with TDD-FDD carrier aggregation with no additional changes to the network
- Load balancing between TDD- and FDD-LTE networks ensures the best coverage and speed for all subscribers in both networks
Abdullah Alzmame, vice president, Networks, STC, said: "We have a strong track record with Nokia: Early this year we launched carrier aggregation on the TDD layer, doubling available throughput for our customers. In 2011, we provided commercial service on a TD-LTE network which now covers most of the Saudi population. With this new achievement, we enter the next level to improve speeds for consumers."
Hani Dib, head of STC customer team at Nokia Networks, said: "We believe that the optimal use of spectrum is key to satisfy ever-increasing subscriber demand for network capacity and speed. Our achievement with STC will encourage other operators globally to look at this kind of spectrum convergence to save costs and increase throughput."
Did you know?
Nokia Networks and China Telecom were the first to achieve a TDD-FDD carrier aggregation with a commercial user device chipset. This successful interoperability is a milestone towards commercial adoption of the carrier aggregation to significantly improve the LTE network speed and coverage for users in areas where both variants of LTE are deployed. Also by aggregating 10 spectrum frequencies allocated for both LTE variants for a massive 200 MHz of bandwidth, Nokia and SK Telecom reached a throughput speed of 3.78 Gbps.
