UK MNO Mobile Spectrum Holdings

Picture Source: Keith Dyer

In a recent consultation document on 'Award of the 700 MHz and 3.6-3.8 GHz spectrum bands' that the UK regulator Ofcom has published (link), there is a nice summary picture (pg. 62 or pg. no. 60) of all the current spectrum holding by the big 4 MNOs.

Looking at this, one can conclude that all the UK operators have spectrum to launch basic 5G services whenever they are ready.

Thailand: Onward to 5G

Thailand has a highly developed mobile market and has experienced strong growth over the last six years driven by increasing numbers of 4G mobile subscribers.However, growth has slowed over the past few years due to the heightened level of maturity. Very slow growth is predicted over the next four years to 2023 with annual growth rates further easing. The market will be constrained from higher growth due to a saturated mobile subscriber market and strong local competition. 

There are 3 main Mobile Network Operators in Thailand, which hold about 97% market share.  In addition to the large 3, there are several smaller MVNO networks.


AIS has the largest 2G/3G network with a 50% customer share. It's part of the SingTel Corp. that also owns e.g. Optus in Australia and SingTel in Singapore. Surprisingly, AIS was the last major provider to start 4G/LTE in 2016 on the 1800 and 2100 MHz band, partly marketed as "4.5G" or LTE Advanced. It now covers 80% of the population in 2017.

The operator has 3G/DC-HSPA on 900 and 2100 MHz (and roaming on TOT 2100 MHz) and started in 2016 with 4G/LTE Advanced called "4.5G" on 1800 and 2100 MHz (bands 1 and 3).

AIS was ranked in second place on which operator has the best 3G and 4G speeds, availability and latency, with 89.22 percent availability by Open Signal.

The market leader has been granted approval by the National Broadcasting and Telecommunications Commission of Thailand to trial 5G on the 26GHz band. They were to conducting testing at the end of 2018. Market leader AIS will conduct the tests in partnership with Nokia. 

dtac is Thailand's 3rd largest network by the number of users. It's partly owned by Telenor group from Norway and is the network that owns the biggest wireless bandwidth in the country

They started 4G/LTE in 2014 on 2100 MHz (B1) in Bangkok only and has been expanded in 2015 to Phuket and Pattaya and another 40 cities nationwide: 4G coverage map. In 2015 4G/LTE was started in the metro Bangkok area mostly on the additional 1800 MHz (B3) frequency which is much more common internationally. In June, 2018 DTAC started offering 4G+ on the 2300 MHz frequency through a deal with Telecommunication of Thailand (ToT). This operator has still to apply to run 5G trials. 

TrueMove is Thailand's 2nd largest network and the most heavily advertised. TrueMove is part of the larger True Corp. conglomerates, owned by CP Group which is the biggest retailer owning all 7-Eleven and Tesco stores in Thailand.

They were the first provider in to bring 4G/LTE on the rare 2100 MHz to Thailand. Its 4G/LTE coverage is the best so far in the country according to Open Signal and comprises 80% rising to 96% by the end of 2016. In 2015 the much more usual 1800 MHz band was added for 4G/LTE as well as 850 and 900 MHz in 2016.

TrueMove will be undertaking 5G tests in partnership with Huawei. 

My is a MVNO operated by CAT Telecom Public Company Ltd., the state-owned company that runs Thailand’s international telecommunications infrastructure, including its international gateways, satellite, and submarine cable network connections. 

It's the 4th largest mobile network operator in Thailand and owns spectrum on the 850 Mhz frequency, rents it out to True Move. In return it can use 20% of the bandwidth for their own My by CAT operation.

My has only 3G/HSPA+ on 850 Mhz (= B5) without fall-back to 2G. As My uses the same 850 MHz network as True Move, their 3G coverage is the same. By 2014 it had a coverage of approximately 97% of population and consisted of around 14,000 BTS. But as there are way less users on CAT's 20% share as they have roughly a market share including MVNOs of 1-2% so far.

4G certainly changed people's lifestyles, but 5G is expected to have a bigger socioeconomic impact, transforming industries ranging from agriculture and manufacturing to healthcare and utilities. Regarding 5G: Thailand has to overcome some major obstacles in order to successfully transition to the next generation technology. For example the financial burden shouldered by telecom operators, including a combined cost of 270 billion baht for the previous 3G and 4G licences; how more spectrum bandwidth has to be allocated; and the telecom regulator's authority, as only an acting board now manages the National Broadcasting and Telecommunications Commission (NBTC). 

The NBTC is encouraging all 5.2 million 2G subscribers to transfer to 3G and 4G systems. The telecom regulator is set to shut down the existing 2G network by October 2019 to give mobile operators more efficient network capacity this will help pave the way to 5G wireless broadband service by 2020. 

Because of 5G's improved speed, latency and connections, mobile operators must hold additional spectrum bandwidth of at least 100MHz (100x2) for upload and download for each service provider. Takorn Tantasith, secretary-general of the NBTC, said he is seriously concerned about "insufficient spectrum holding" by each operator, which would affect 5G ecosystem adoption. 

After the most recent spectrum auction, AIS holds the most spectrum bandwidth, with a combined 60x2MHz, followed by True Move at 55x2MHz and DTAC at 50x2MHz. The NBTC is on the verge of recalling unused or not fully used spectrum ranges from holders to auction them off to serve 5G.

Somkiat Tangkitvanich, president of the Thailand Development Research Institute, states there are three critical factors needed for the domestic telecom industry to ensure real public benefits in 5G adoption. 

The three factors are real liberalisation of the telecom industry, good regulations and a spectrum allocation roadmap. 

Liberalisation, would be allowing foreign stakeholders to hold more than a 50% stake in a company, will create healthier competition and eliminate chronic problems fostered by state-owned enterprises such as corruption and limited procurement transparency. While good policy design and regulations will help eliminate unfair competition among players and reduce high operating costs in some cases, according to Mr Somkiat.

However Mr Somkiat disagreed with the idea of providing assistance for AIS and True Move, the two winners of the 900MHz licence auction. He said they did not deserve state assistance because they bid up the prices by themselves. He also stated AIS and True Move operate mobile services with profit from operations and have the capability to pay the remaining sum of their 900MHz licences due in the next two years.

Telefónica's AI based assistant, Aura, is serving more than 1.5 million customers per month in Brazil

In an earlier post, I talked about Telefónica's launch of Aura at MWC 2018. Aura is an artificial intelligence-powered digital assistant that is designed to transform the way customers interact with Telefónica and manage their digital life with the company. They first release of Aura was made available in Argentina, Brazil, Chile, Germany, Spain and the United Kingdom.  Aura is available on customer devices via a mobile application and also via other third-party channels including Facebook, Google and Microsoft.

Anyone interested in details of Aura can check out the official page here.

In a recent news by Vivo (brand of Telefónica) Brazil, Aura is already serving more than 1.5 million customers per month. Accroding to the press release (translated via Google translate):

About to complete its first year of life, Aura, artificial intelligence of Vivo, already serves more than 1.5 million customers per month, responding in a personalized way on services, data consumption, account, recharge, among other questions of the subscribers. And since its launch in February 2018, Aura has already made approximately 20 million calls. 

The Aura retention rate is higher than 80%, that is, eight out of 10 customers are satisfied with the response given by Aura and do not need other information. Aura is available in different service channels, among them Facebook Messenger, My Vivo Mobile, Meu Vivo Fixo and Meu Vivo Empresas, and the Vivo site, among others.

Since the end of 2018, Aura also serves the call center - hourly, in a pilot project in a DDD of the State of São Paulo. And, to further improve the quality of service provided by Aura, Vivo inaugurated its Bots Training Center last year. The new area looks at whether Aura correctly understands customer doubts and generates inputs to correct and train the bot, and assess whether Aura's response really clarifies the customer's question, thereby ensuring continuous improvement of the customer experience. users. 

There is also an official YouTube video demonstrating Aura but it doesn't say much. There is an unofficial one that demonstrates how Aura works.

Just a matter of time before majority of customer services are handled by bots and AI assistants.
