China Telecom Tests 260 Mbps FDD- TDD Carrier Aggregation with Nokia

China Telecom, in partnership with Nokia Networks, has demonstrated the world-first FDD-TDD carrier aggregation including a user device chipset.

In the demo, Nokia’s LTE base station achieved interoperability with a commercial user chipset developed by Marvell. A stable peak download speed of 260 Mbps was achieved in the carrier aggregation demonstration with FDD 20 MHz in 1.8 GHz and TDD 20 MHz in 2.6 GHz spectrum. For the total speed, FDD spectrum contributed to 150 Mbps while TDD spectrum contributed to 110 Mbps.

“It’s highly satisfying to achieve yet another world-first* toward commercialization and globalization of FDD-TDD carrier aggregation,” said Zhang Qi, Vice President of TD-LTE, Nokia Networks. “This achievement with our partner China Telecom will also encourage other operators globally to look at further spectrum combination for FDD-TDD carrier aggregation into advanced 3GPP Rel-12. We are already working with many major operators globally to deliver FDD-TDD convergence for commercial use.”

AVG Technologies to Acquire Location Labs for $140 Million

Amsterdam-based AVG Technologies N.V. agreed to acquire privately-held Location Labs, a start-up based that that uses location awareness to provide mobile device management and protection, for approximately $140 million initially, plus up to an additional approximately $80 million in cash consideration over the next two years based on the achievement of certain performance metrics and milestones.

Location Labs’ integrated platform for mobile operators, pre-installed service on Android smartphones, and mobile subscription services including family, safety and personal device management, are all expected to complement and expand AVG’s existing mobile offerings. The company is based in Emeryville, California.

AVG said the acquisition significantly broadens its position as the online security company by accelerating its mobile security business. With the acquisition and organic growth, AVG is creating a global business that should generate $60-70 million in mobile bookings in 2015, and anticipates this scaling to around $100 million in mobile bookings in 2016.

“Location Labs has effectively cracked the code for mobile monetization through its highly successful business model with industry partners. This acquisition significantly accelerates AVG’s mobile strategy in this area,” said Gary Kovacs, Chief Executive Officer, AVG Technologies. “According to industry estimates, the number of mobile-connected devices will exceed the world’s population by the end of this year alone. The combined existing mobile user base of both companies gives us the unprecedented opportunity to deliver online security to approximately a quarter of a billion devices as we see more people go mobile to get online.”

Nokia Announces Metro Remote Radio Head, Software Enhancements

Nokia Networks announced its the Flexi Metro Remote Radio Head (RRH), 60MHz carrier aggregation for LTE and new software features for its Liquid Radio platform.

The new Nokia Flexi Metro RRH for LTE is designed for extremely dense networks in the busiest metropolitan areas using existing macro network sites. Nokia said the RRH’s sensitivity can be tuned and output varied from 2 x 5W down to 2 x 50mW to match any deployment’s need for high capacity mobile broadband. Combined with Nokia’s Centralized RAN, the Nokia Flexi Metro RRH allows more cells to be concentrated in a given area.

The software enhancements to Nokia Networks LTE-Advanced Carrier Aggregation enable evolution to 60MHz aggregation bandwidth in LTE and TD-LTE, delivering up to 450 Mbps peak downlink rates, as supported by upcoming Category 9 devices.

The company is also launching Enhanced HSUPA Interference Cancellation, a new Liquid Radio WCDMA Software Suite feature that reduces interference for up to 60% gain in uplink throughput to fit up to 30% more users per cell.

Some other new capabilities:

  • HSPA Carrier Aggregation with Dual-Band HSDPA: uses two 5MHz WCDMA carriers on different bands to double downlink peak rates to up to 42Mbps and Dual-Cell HSUPA enables devices to upload data simultaneously over two adjacent carriers to raise peak transfer rates to 11.5Mbps - both supported by upcoming terminals.
  • LTE-WCDMA and LTE Intrafrequency Load Balancing for effective load balancing: helps operators eliminate congestion in highly loaded networks and better optimize resources between users.
  • HSPA rapid receiver for high-speed trains enables operators to deliver better voice quality and faster uploads for passengers commuting (at 250-350 km/h) in and out of megacities and other busy areas.
  • Nokia’s Services for HetNets help solve the complexities of deploying high density networks for operators. Overall costs can be reduced by adding capacity in an intelligent manner, only where and when it is needed. Advanced planning and optimization services ensure that all layers of the network work seamlessly for subscribers.

“Operators are densifying their networks by splitting macro cells or adding more network layers for the vital extra capacity needed especially in metropolitan areas,” said Thorsten Robrecht, vice president, Mobile Broadband portfolio management at Nokia Networks. “As the distance between cells decreases and network layers increase, mobile devices cause greater interference. Liquid Radio realizes the full performance of high density macro networks with increased cell density, less interference and maximum throughput.”
