China Unicom launches LTE-Broadcast and Gigabit LTE with Ericsson

China Unicom commercially launched a Gigabit LTE network.

On August 23, passengers on a Hainan Island high-speed train were able to watch the lauch ceremony via LTE broadcast over the Gigabit wireless network. Ericsson, as China Unicom's strategic partner, is the exclusive provider of the LTE broadcast solution, which is China's first LTE broadcast commercial deployment. Ericsson also provided the Gigabit LTE network upgrade.

Hao Liqian, General Manager, Hainan branch, China Unicom, says: “This remarkable achievement will fulfill our strategy to offer the most advanced services to individuals and enterprises on the China Unicom network. Our launch ceremony today is important, innovative and fun, since we’re using Virtual Reality on a high-speed train over a high-speed network to prove the worthiness of this launch.”

Chris Houghton, Head of Market Area North East Asia, Ericsson, says: “We’re literally putting the network into the hands of the subscribers on day one.  People will be able to immerse themselves in their video experience and not just understand, but feel, the difference with a Gigabit LTE network while they are moving at very fast speeds.  It’s the perfect combination of thrilling speeds – physically and virtually.”

Ericsson said LTE broadcast will revolutionize video delivery in mobile networks enabled by the combination of three new standards: eMBMS, HEVC (H.265) and MPEG DASH/

Recently, Ericsson supported China Unicom in setting up a 1Gbps network in Guangdong, Hainan, Shandong, and Beijing with peak speeds of up to 979Mbps. With that speed, it takes just 13 seconds to download a 1080P high-definition movie. There are more on-going 1Gbps trials in Sichuan, Hubei, Shanxi, Jilin and Jiangsu province. A high-speed mobile broadband network will enable businesses and services using Artificial Intelligence, Virtual Reality and other big data operations.

Verizon, Ericsson, and Qualcomm hit 1.07 Gbps peak

Verizon, Ericsson and Qualcomm Technologies announced a new peak downlink speed of 1.07 Gbps using the Qualcomm Snapdragon X20 LTE Modem, the first announced modem to support Category 18 LTE speeds.

The new record was achieved during an Ericsson lab trial. using 12 simultaneous LTE streams, which allow for up to 20 percent increase in peak data rates and capacity with a corresponding improvement in average speeds. Ericsson's Radio System and LTE software was used in concert with a mobile test device based on the Snapdragon X20 LTE modem.

In the lab, the 1.07 Gbps speeds were achieved using all licensed band combinations with:

  • 12 LTE streams with 3 cell carrier aggregation of FDD spectrum
  • 4x4 MIMO per carrier (multiple in, multiple out), which uses multiple antennae at the cell tower and on consumers devices to optimize data speeds
  • 256 QAM per carrier, which enables customer devices and the network to exchange information in large amounts, delivering more bits of data in each transmission, significantly enhancing data speeds

Verizon said this 1.07 Gbps achievement builds on its recent announcement about Gigabit LTE with support for License Assisted Access (LAA). Also of significance, the 1.07 Gbps speed was achieved using only three 20MHz carriers of FDD (Frequency Division Duplex using separate transmit and receive frequencies) spectrum, achieving new levels of spectral efficiency for commercial networks and devices. These efficiencies will enable the delivery of the Gigabit class experience to more customers and lead to new wireless innovations.

"As technology leaders, Verizon continues to drive innovation for our customers. Today's achievement shows once again that while Verizon deploys the most advanced technologies to our customers in the real world environment, we are always looking ahead to what customers will need tomorrow," said Nicola Palmer, Verizon Wireless Chief Network Officer.

nbn demonstrates 1.1 Gbit/s data rate in fixed wireless trials

Australia's nbn announced that it has achieved gigabit transmission speeds during a fixed wireless technology demonstration conducted in Ballarat, Victoria.

For the trial, nbn used 2.3 and 3.4 GHz spectrum as part of its ongoing effort to employ the appropriate advanced technology to meet both current and future bandwidth demands within its multi-technology mix (MTM) strategy. The latest demonstration achieved 1.1 Gbit/s downstream and 165 Mbit/s upstream speeds utilising carrier aggregation technology to combine seven carriers in the 3.4 GHz band and four carriers in the 2.3 GHz band.

As part of the demonstration nbn also delivered trial peak downstream/upstream speeds of 400/55 Mbit/s, 250/50 Mbit/s and 100/40 Mbit/s using a range of carriers in the 2.3 and 3.4GHz spectrum bands.

nbn noted that the 1.1 Gbit/s transmission speed was achieved by bonding together three next generation wireless network termination devices (WNTDs) - the antennae located on the roof of a nearby school - while the lower speeds were enabled via a single WNTD. The trial involved the use of a spare operating sector on an established nbn fixed wireless tower and the installation of additional radio equipment.

The trial was conducted with nbn's fixed wireless technology partner Ericsson, NetComm Wireless and Qualcomm, with the speed tests carried out utilising technology from Mill Software.

nbn has previously committed to launching a new wholesale nbn100 fixed wireless product targeting the regional business segment in 2018, and the latest high speed fixed wireless technology demonstration was designed to illustrate its ability to launch faster services over the nbn fixed wireless network. nbn anticipates that around 600,000 premises in regional Australia will be served by the fixed wireless network.

Earlier in April, nbn announced it had partnered with Nokia to trial NG-PON2 technology that could potentially enable symmetrical speeds of up to 10 Gbit/s for FTTP services. nbn noted that NG-PON2 could also enhance services for FTTB and fibre-to-the-kerb networks combined with technology such as G.fast and XG.FAST, as well as providing extra capacity over fibre supporting its HFC and fixed wireless networks.


During trials in Melbourne, NG-PON2 delivered bandwidth of up to 102 Gbit/s in the lab, based on 40 Gbit/s symmetrical speed using TWDM-PON technology, 10 Gbit/s symmetrical on XGS-PON and a further 2.5 Gbit/s with current GPON technology.

Comcast Readies 2 Gbps Residential Service in California

Comcast will roll out its residential multi-gigabit broadband service to nearly three million California homes starting in June.  Gigabit Pro is a symmetrical, 2 Gigabit-per-second service that will be delivered via a fiber-to-the-home solution and offered to customers in the Chico, Fresno, Marysville/Yuba City, Merced, Modesto, Monterey, Sacramento, Salinas, San Francisco Bay Area, Santa Barbara County, Stockton and Visalia metro areas.

In addition, Comcast announced its 15th speed increase in 13 years for its other broadband Internet tiers. The company will increase its Performance tier from 50 Mbps to 75 Mbps and its Blast tier from 105 Mbps to 150 Mbps, both at no additional cost to customers.

Comcast noted that it has been doubling the capacity of its network every 18 months.  Additionally, the company has been delivering multi-gig (up to 10 Gbps) Ethernet service to businesses in California since 2011.
