ITU makes it Official: 5G is IMT-2020

In addition, the ITU vision and roadmap for the 5G standard defines 5G as networks capable of transmitting data at up to 20 Gbps. In addition, the ITU has declared that 5G networks will have a capacity to provide over 100 Mbps data rates to over 1 million IoT devices within one square kilometer. Unfortunately, nobody knows how we will get to these performance figures.

Presumably, the technology will become available about the year 2020. However, I doubt that will be achieved since LTE Carrier aggregation will continue growing network capabilities over the next 5 years and beyond. See chart below. Note that only one U.S. network (Sprint) has fielded Cat 6 on a general rollout.

China Telecom Rolls out World’s Largest FDD-LTE Network

On August 1st, China Telecom announced that it has completed construction 460,000 LTE base stations in 17 cities, providing it with the world’s largest FDD-LTE network. What’s more, the network has adopted carrier aggregation technology for Category 6 (Cat 6) LTE-A operation (300 Mbps down link and 50 Mbps up link). Of course, having a Cat 6 network requires smartphones capable of Cat 6 LTE-A operation. Currently, U.S. cellphones with that capability employ only Qualcomm modems, but its competitors have “announced” chips with that capability, but none have been observed shipping in Cat 6-capable cellphones…yet.

Marvell Claims First to Launch Inexpensive Rel. 10 LTE Modem

This week Marvell announced a “cost-effective” LTE-A platform with carrier aggregation with 20+20 MHz support for Cat 7 operation (see chart). The quad-core (1.5 GHz) 64-bit ARMADA Mobile PXA1918 features an ARM Cortex-A53 processor and supports all cellular standards except CDMA.

Also announced this week was AT&T data and voice (VoLTE) validation of Marvell’s ARMADA PXA1928 (1.5 GHz) and PXA1908 (1.2 GHz) multimode Cat 4 LTE solutions. Both platforms also feature quad Cortex-A53 processors.

Qualcomm Completes CSR Acquisition

Cambridge Silicon Radio Ltd. has become Qualcomm Technologies International Ltd. The $2.4 billion acquisition is now a wholly-owned subsidiary of Qualcomm Technologies adding new products and customers in the areas of audio, IoE and automotive, key growth priorities for Qualcomm.

Cellphone Layoffs Continue

It’s going to be a long hot summer for the smartphone world. Last month, I announced the pending layoffs at Qualcomm, Marvell and Microsoft’s cellphone operation. This month, Lenovo and its subsidiary Motorola have announced restructuring, with Motorola taking over Lenovo’s Smartphone Division, leading to layoffs of 500 jobs at Motorola’s Chicago headquarters and 3,200 Lenovo workers. Sony is reported to be laying off 2,000 of its 7,000 mobile unit workers. Blackberry is making an unknown number of job cuts. HTC has announced that it is cutting 2,250 people by the end of the year, amounting to some 15% of the company workforce. Likely, there will be more such announcements coming.

As always, I encourage your feedback.
