China preps ground for 5G with plea for C-band spectrum


LIVE FROM GSMA MOBILE WORLD CONGRESS SHANGHAI: China is devoting substantial resources to accelerate the development of 5G, because existing technology won’t be able to keep up with the country’s soaring data demand.

Xie Feibo, director general of the Radio Regulations Bureau, Ministry of Industry and Information Technology (MIIT), said the reason behind this push is simple: China has the largest population in the world, which means at some point it will have the largest data flows.

“Currently technologies are not sufficient to handle the coming data flows as we move from human-to-human communications to M2M, and spectrum in the future has to support broadband and narrow-band channels. Each square metre will have at least one million connections. So how much spectrum do we need? It’s a huge amount. The government has given me the very big job to find a way to support these future data flows,” he said.

During his presentation today, in the Collaboration in Asia for Spectrum for 5G session, Xie said the government’s attitude towards 5G has been extremely supportive, with initiatives to mobilise all of the ministry’s resources to enable developments.

He called on all players in the mobile ecosystem to “please concentrate” on C-band spectrum to prepare for the early adoption of 5G. China is focused on the 3.3-3.6GHz band in the first phase. He acknowledge that this band will not be enough, so the industry also needs to adopt new principles, the most important of which is sharing.

“Please prepare to accept this concept and start looking to share network resources with other radio services, such as the satellite industry, which can create new opportunities. In the new age of spectrum usage, spectrum sharing is key,” he said.

John Giusti, chief regulatory officer at GSMA, explained that long-term spectrum planning is essential even at this early stage of 5G development, with collaboration and harmonisation essential to success.

“China, Japan and South Korea have an unprecedented opportunity to work together to harmonise spectrum, particularly as we look above 6GHz.”

Giusti also noted that as we talk about 5G we shouldn’t lose focus on current networks, since LTE and 3G will be what most people use to connect for the foreseeable future.

OFCOM announce more radio spectrum for the Internet of Things

Ofcom-HQUK Telecommunications and broadcasting regulator Ofcom, has announced measures to help ensure adequate spectrum is available for the ‘Internet of Things’ (IoT), and to encourage investment and innovation in this developing technology.

Ofcom is allocating 10 MHz of VHF spectrum which will enable certain IoT devices to connect wirelessly over long distances. Access to spectrum in this range could open new opportunities and bring benefits to consumers, especially those in remote and rural parts of the UK. The frequencies being made available span the 55-68 MHz, 70.5-71.5 MHz and 80.5-81.5 MHz bands.

These frequencies could be used by Machine-to-Machine (M2M) applications to enable wireless operation over long distances and will help deliver valuable new services for the benefit UK consumers and businesses. The allocation will boost innovation across a number of different verticals including: agriculture, smart farming and an array of coastal and maritime industries.

According to the regulator, there are already more than 40 million devices connected via the IoT in the UK alone. This is forecast to grow more than eight-fold by 2022, with hundreds of millions of devices carrying out more than a billion daily data transactions.

The news follows the regulator’s release of a consultation document in September 2015, which invited stakeholders to comment on proposed changes the existing Business Radio licence to accommodate the IoT.

Three annonces 4G rollout plans for 47 UK Cities

London, Manchester and the Midlands get Three 4G this year

Mobile phone operator Three has become the last to announce the launch of 4G services, saying it will offer them in four major cities by the end of 2013.

Three will start with London, Manchester, Reading and Birmingham.

A further 42 will follow by late 2014 as part of a drive to cover 90% of the UK’s population with 4G services by the end of 2015.

Comparing with other operators, EE already covers over 55% of the population, and O2 and Vodafone turned on their services in August.

Despite starting later than its larger rivals Three will not lose out, says Carrie Pawsey, senior communications analyst at the consultancy Ovum.

“In the early interim period it will make no difference. Apart from EE, the other networks won’t have a significantly larger coverage area.” But, she added, “Three is likely to have larger blackspots for 4G coverage in the long term.”

Three will be using a slice of the high-frequency 1800MHz band allocated for 4G which it won in an auction overseen by telecoms regulator Ofcom.

Three also bought 4G spectrum in Ofcom’s 4G auction in February at the 800MHz band, which has lower bandwidth than 1800MHz but longer reach.

Pawsey said: “It may hurt its market share in the long term, as the other networks expand to cover more of the country and are able to offer higher average speeds”

EE was first to launch a 4G service in the UK on 30 October 2012, well ahead of the Ofcom auction by “re-farming” spectrum it already owned on the 1800MHz band.

After an aggressive rollout, it now covers more than 100 towns around the UK and has over 1 million customers using 4G.

Faster broadband coming to planes, trains and ships as UK eyes spectrum changes

The UK is looking to open up spectrum currently used by satellite Earth stations for vehicle-mounted stations that could boost broadband capacity in aircraft, ships and trains.

The UK’s communications regulator Ofcom is hoping to spur innovation in mobile broadband services by making it easier for satellite operators to use ‘Earth stations on mobile platforms’ (ESOMPs) to deliver passenger broadband.

Ofcom has proposed (PDF) three frequency bands that operators could apply for to support mobile Earth stations mounted on aircraft, ships or other land-based vehicles.

While alternative technologies are already used to provide wi-fi on board in transport, the regulator believes the spectrum could be used to provide links with higher capacity and spur a new market for mobile communications.

Several satellite operators are planning to launch commercial satellite networks in 2013 and 2014 that support the use of mobile earth stations transmitting in the 27.5GHz to 30GHz range, according to Ofcom.

Ofcom also points out that recent advances in stabilised antenna technology make it possible for earth station antennas to track a satellite in orbit even when it’s mounted on a fast moving platform.

While there was a risk the mobile Earth stations could cause interference to other fixed site satellite networks, Ofcom considered that risk “very low”. With the appropriate controls, the mobile stations would cause no more interference than fixed-site earth stations, it said.

It also notes that the aircraft and ship-mounted Earth stations can already operate in international airspace and waters, but that parts of these frequency ranges are used by terrestrial radio systems in some countries. That’s why Ofcom was proposing frequency ranges that are already authorised for satellite Earth station applications, such as the permanent Earth stations and high density fixed-satellite services.

Key proposals Ofcom is seeking feedback on under a public consultation are:

  • Radio equipment for land-based ESOMPs should be exempted from the need to have a Wireless Telegraphy Act 2006 licence
  • Radio equipment for aircraft and ship mounted ESOMPs should be licensed under the Wireless Telegraphy Act 2006 rather than licence-exempt
  • Licensing of aircraft-mounted ESOMPs should be done through variation of the aircraft radio licence issued on Ofcom’s behalf by the Civil Aviation Authority (CAA) with no additional fee
  • Licensing of ship-mounted ESOMPs should be done through variation of the ship radio licence with no additional fee.

The deadline for stakeholders to respond to the proposal is 10 October 2013 and Ofcom expects to release a statement on the consultation in December.
