  2. 2. Abstract The advancement and growth of the Internet is causing network congestions across the globe due to heavy data consumption required by its applications. However, with different penetration levels and usage patterns, there is a contrast for network congestion in developed and emerging countries. The network congestion issue in developed nations is more acute although current network technologies are advanced but yet they are insufficient to cope with data requirements. The only way forward is to continue upgrading to faster networks with higher capacity, but this option requires heavy investment in terms of time, effort and money. What then is a more cost-effective alternative? This paper studies Hong Kong*, a densely populated country with one of the world’s fastest growing telecoms sector and a victim of network congestion. Greenpacket presents a case study on how a cellular operator can battle network congestion without burning a hole in the pocket. *Hong Kong is selected as it is a small country with a huge population and easily comparable to any other major city in the world. The objective here is to help readers understand that network congestion as experienced by Hong Kong and proposed solution can be applied to most dense areas around the world. WHITEPAPER

  4. 4. Network Congestion Phenomenon: Developed vs. Emerging Markets Across the globe, escalating data traffic is leading to network congestion, a phenomenon that the telecommunications industry dreads. However, developed and emerging markets undergo network congestion which is different in nature due to the disparity in broadband penetration levels which leads to dissimilar usage patterns (user perspective) and business models (operator perspective). Generally, broadband penetration exceeds 35% in developed markets but barely touches 10% in most emerging markets. Figure 1 maps the broadband penetration rates of developed and emerging markets worldwide. Developed nations have a higher broadband penetration rate compared to emerging nations.

  5. 5. Causes of Network Congestion In Greenpacket’s earlier whitepaper Operators Can Save $14 Million Yearly Through Data Offloading (Note: You will need to complete a form to download the whitepaper), we mentioned that congestion occurs when throughput supply is lower than demand. This can be the result of too many users within a site or when the throughput level is too low. Typically, networks in emerging countries have low throughput levels such as 3.6Mbps or 1.8Mbps, in contrast to developed countries with 14.4Mbps networks and above. This condition contributes to network congestion in emerging countries. Figure 2 compares developed and emerging countries that have approximately the same build up area. As such, it can be assumed that almost equal number of network sites is required to provide coverage. Many operators in emerging countries support the same/more subscribers on networks with lower data rates. This situation leads to network congestion. For example, let’s compare Japan and Philippines. Smart (PLDT) serves 38 million subscribers on a 2.0Mbps network, as opposed to SoftBank Mobile which caters for only 21 million subscribers on a 7.2Mbps network. Country Economic Area HSDPA Supported Remarks Status (in km2) Data Rate Subscribers Czech Developed 78,866 14.4Mbps 2.9 million Both operators support the same number of Example A Republic subscribers but T-Hrvatski Telekom has a Croatia Emerging 56,594 7.2Mbps 2.9 million lower data rate. Hence, congestion occurs. Japan Developed 377,835 7.2Mbps 21 million Smart (PLDT) supports Example B more subscribers but its network has a much lower data rate against Philippines Emerging 300,000 2.0Mbps 38 million SoftBank Mobile’s data rate. Source: GSMA, BMI Figure 2: Operators in emerging countries support equal or more subscribers on networks with low throughput levels On the other hand, in developed markets, users are more mature Internet users and therefore engage in heavy data usage that demands higher bandwidth. The Internet is relied upon beyond information gathering and communications. Instead, it is heavily used for entertainment, especially video content and applications. According to research firm Sandvine, users in North America and Europe are the highest consumers of YouTube videos, as shown in Figure 3. 02 WHITEPAPER

Greenpacket has selected Hong Kong for a market study as this country has soaring subscriber numbers within a small land area. Additionally, Hong Kong has one of the fastest growing telecoms sector that is afflicted by network congestion. In this paper, we present a case study on how a cellular operator facing network congestion benefits from an immediate, simple and cost-effective measure to combat the issue without heavy investments in network upgrades. 03 WHITEPAPER
  7. 7. Getting to Know Hong Kong’s Telecoms Market Demographics & Economy Hong Kong is situated on China’s southern coast with a land mass of 1,085km2. With a population of over 7.08 million (6,502 persons/km2), Hong Kong is one of the most densely populated areas in the world, in comparison to Netherlands for example, which has a land mass of 45,526km2 and population of 16.6 milion (399 persons/km2). The density level of Hong Kong is so high that it even exceeds the density level of some of the world’s most populous cities such as London (4,863 Image source: Wikipedia persons/km2), Bangkok (4,478 persons/km2) and Figure 4: Map of Hong Kong even Amsterdam (4,459 persons/km2)! Hong Kong is also one of the world’s leading developed nations, holding a GDP per capita of USD 31,849 in 2008, which is relatively higher compared to other countries (see Figure 5). One of the reasons for Hong Kong’s high GDP levels can be associated with its high broadband penetration rate and vice versa. 30% Hong Kong South Korea 25% Canada Switzerland 20% Belgium Broadband Penetration France USA 15% Spain 10% China Hungary 5% Brazil Indonesia Mexico UAE Egypt Russia Saudi Arabia 0 0 South $10,000 $20,000 $30,000 $40,000 $50,000 $60,000 Africa GDP per Capita Source: Alcatel-Lucent, 2008 Figure 5: GDP vs. broadband penetration levels of selected countries from around the world 04 WHITEPAPER
  8. 8. Telecoms Background Hong Kong has one of the most advanced and sophisticated telecommunications market in the world and this has been one of the driving factors in shaping this country as a leading business and financial centre. Hong Kong’s telecommunications sector has been liberalized to set a platform that is both pro-competition and pro-consumer. This objective provides a fair playing ground in the telecoms market and ensures consumers receive best-in-class services in terms of capacity, quality, coverage and speed. Office of the Telecommunications Authority (OFTA) is the governing statutory body responsible for regulating the industry. Strong governmental support, enormous connectivity infrastructure and geographical advantage of compact size have led to Hong Kong’s successful Internet evolution. Figure 6 compares the broadband technology evolution of Hong Kong and the United States. It is evident that Hong Kong has been almost at par with United States which illustrates the former’s impressive growth in the Internet and broadband arena over the past two decades. 2G 3G 3.5G HSUPA Hong Kong GSM PCS GPRS HSPA+ WCDMA/ HSDPA CDMA (GSM EDGE 2000 1800) (EVDO) United States CDMA UMTS/ GSM One HSPA+ WCDMA HSUPA PCS 1900 GPRS EDGE HSDPA (GSM 1900) ‘93 ‘94 ‘95 ‘96 ‘97 ‘98 ‘99 ‘00 ‘01 ‘02 ‘03 ‘04 ‘05 ‘06 ‘07 ‘08 ‘09 Figure 6: Hong Kong and United State’s Internet and broadband evolution Hong Kong’s Telecoms Market Today Hong Kong is an extremely networked society gauging from its high infiltration rates from the broad telecoms perspective, as shown in Figure 7.

  9. 9. As far as broadband is concerned, the services are highly in use which explains Hong Kong’s high broadband penetration rate. At 82%, Hong Kong is ranked among the top three markets with highest household broadband penetration rate (Figure 8) and fastest average Internet connection speed (Figure 9).

To date, Hong Kong has 14 fixed network operators (FNOs), five mobile network operators (MNOs) and nine mobile virtual network operators (MVNOs). Such intense competition makes broadband services in this country very affordable. The combination of high penetration rate and affordable pricing formed an ideal platform for IPTV services which 06 hit 1.2 million subscribers as of December 2009, again one of the highest in the world. WHITEPAPER
  10. 10. Aside from IPTV, Hong Kong has a strong network of WiFi hotspots – there were more than 8,900 public WiFi hotspots as of March 2010 and growing. An average Hong Kong Internet user spends more than 25 hours online per month, making it one of the most engaged Internet markets globally. Online communications, entertainment and social networking take up the highest share of minutes spent online (see Figure 10). Several interesting Internet usage behaviour includes the following: • Instant messaging holds the highest share at 16% (October 2009), which is almost double the time spent by Asia Pacific region as a whole • Entertainment is led by video-based applications led by YouTube and • Social networking is led by Facebook • 5% of Internet minutes are spent on business and finance sites which reflect the country’s business and finance focused economy.

  11. 11. Issues Facing Hong Kong’s Mobile Broadband Landscape Cellular Networks Face Ceiling-level Data Usage Data usage on Hong Kong’s cellular networks is at extremely high levels which explains the reason for network congestion. How do we know this? i) The number of cellular users in Hong Kong has reached 100% of active users (active users refer to population aged 15 to 65 who are in employment or expected to enter employment). Figure 11 shows that the number of cellular subscribers (2.5G and 3G) slighly exceeds the total number of active users – this concludes that all active users in Hong Kong are enjoying Internet through their mobile broadband connections. Mobile subscribers (January 2010) 12,483, 989 2.5G and 3G mobile subscribers (January 2010) 5,275,365 No. of cellular subscribers equal % of active users 74.8% 100% active users Total number of active users 5,206, 000 Source: BMI, Q1 2010 Figure 11: Cellular users vs. total number of active users ii) Tremendous increase in data usage. Since the launch of HSDPA in 2006, subscriber count only increased 2.4 times but data consumption grew immensely by 80 times!

  12. 12. Why is Hong Kong experiencing such a gigantic leap in data usage? Here are some reasons: a. Affordable broadband rates – With the presence of 14 FNOs, five MNOs, nine MVNOs and hundreds of other licensed ISPs, healthy competition exists and keeps broadband rates very affordable for the man on the street. As such, almost the entire active population of Hong Kong is able to afford a broadband connection and use data applications. Data card plans in Hong Kong range from USD 24 to USD 49 which is lower compared to similar plans in United States which range from USD 30 to USD 60. b. High usage of IPTV – Television is loved for its rich visual and audio entertainment qualities. Delivering these qualities over Internet is a definite data gobbler. Hong Kong has 1.2 million IPTV subscribers which are among the highest in the world. c. High usage of smartphones – Hong Kong consumers lead smartphone usage globally. Almost half (48%) of consumers in Hong Kong own a smartphone, which is more than double the global rate of 23% as shown in Figure 12. The smartphone is used to access Internet applications such as email, social networking and even blogging. In today’s world of content and applications, social networking is king. This is obvious in Hong Kong whereby 30% of smartphone users regularly update their social pages compared to 12% globally. Smartphone penetration is approaching majority levels % of mobile users with a Smartphone *Covers Australia, Japan, Korea, Hong Kong, Malaysia, Singapore and Taiwan. 48 40 27 23 Global 2010 Developed Asia* 2010 Hong Kong 2010 Hong Kong 2009 Source: Figure 13: Hong Kong’s smartphone penetration rate exceeds global and Asian levels d. High Public Transport Travel – With the advantage of being geographically compact, Hong Kong has a highly developed transportation network. Over 90% of daily travels take place via public transport. This form of commutation gives subscribers time to enjoy Internet while on the go through their smartphones and other mobile devices. Decreasing ARPU Hong Kong’s telecommunications landscape undergoes intense competition which leads to price wars that sets the ARPU on a downward scale. Figure 13 shows ARPU decreasing for several leading mobile network operators in Hong Kong since 2007. 09 WHITEPAPER
  13. 13. Source: Business Monitor International (BMI), Q1 2010 Figure 14: Decreasing ARPU trend faced by operators in Hong Kong Aside from the price war, the decline in ARPU (Figure 14) can also be attributed to the stronger prepaid growth than postpaid (Figure 15). Although in the past, operators in Hong Kong received higher revenues through postpaid plans, prepaid services are gaining popularity as subscribers are more conscious of their commmunication and connectivity spend. Prepaid ARPU is undeniably much lower than postpaid. For example, in 2008, Hutchison’s postpaid ARPU was almost nine times larger than prepaid ARPU1.

  14. 14. Poor Indoor Coverage Poor indoor coverage has always been a constant battle for wireless technologies. In high density countries like Hong Kong and Singapore, more than 70% of traffic occurs indoor. Analysis Mason anticipates that by 2016, over 80% of global wireless data traffic will be generated indoors. This concludes that indoor capacity demand is much higher and operators must address this issue. Operators currently face numerous complaints on bad indoor coverage from subscribers. In Japan alone, NTT Docomo recorded that over 90% of complaints are due to poor indoor reception quality. It is important to understand that indoor coverage is usually poor because wireless signals originate from base stations which are deployed outdoors. These signals need to penetrate through building material (for example, glass or concrete) and experience radio wave penetration loss of 6 – 13 dB or more which translates into throughput loss as well. Though operators today employ inbuilding solutions to boost coverage, however, in the case of Hong Kong, due to its complex morphology, these solutions are expensive to deploy. Figure 16 gives an overview of typical throughput levels at three different locations from the base station – peak rate (nearest to the base station), median users (mid way distance from base station) and cell edge. At each of this location, throughput levels are lower indoor compared to outdoor.

  15. 15. Case Study – Operator X, Hong Kong (HSPA+ Operator) Technical Background There are four operators in Hong Kong and each has four frequency carriers for a total of 20MHz (three 5MHz bands and one split 5MHz band). This frequency arrangement enables three 5MHz bands to be grouped. 3G 3G 3G Satellite Mobile Operator Operator Operator 3G Operator 3G Operator 3G Operator 3G Operator Service 2 3 1 1 2 3 4 (Exemption Order) 1904.9 1909.9 1914.9 1919.9 1920.3 1935.1 1949.9 1950.1 1964.9 1979.7 1980 2010 MHz TDD Spectrum FDD Spectrum Figure 17: Frequency allocation across four Hong Kong operators Among these four operators, Greenpacket has selected Operator X* for this case study. Operator X is Hong Kong’s leading operator and the first to launch a HSPA+ 28.8Mbps. To deploy and operate a 28.8Mbps network, 5MHz frequency band is sufficient for data while the remaining 15MHz is reserved for voice and/or mobile TV (R99/MBMS). Bandwidth HSPA+ Data Rate LTE Data Rate 5MHz 42Mbps 37Mbps 10MHz 84Mbps 73Mbps 20MHz 168Mbps 150Mbps Figure 18: HSPA+ vs LTE data rates corresponding to different bandwidth levels Since Operator X (and the other operators) are investing huge sums of money into HSPA+, it is necessary to assume that they would most likely adopt the HSPA+ path in coming years which enables data rates of up to 168Mbps through four frequency carriers (20MHz spectrum). These data rates are equivalent to that of LTE as shown in Figure 17. *Name of this operator is withheld to protect its interests Expected Network Cost by End 2010 Going along the path of HSPA+, how much would Operator X need to spend to maintain its network? For this indication, Greenpacket has set certain assumptions and predictions based from our observation. 12 WHITEPAPER
  16. 16. Prediction # 1: Data Usage Operator X’s data usage is at 152TB as at June 2010. Greenpacket assumes that Busy Hour (BH) rate is at 15% with a throughput/user growth rate of 4.3 times on year to year basis. Prediction # 2: Subscriber Growth by 2010 Based on a yearly (subscriber) growth rate of 15% (or 7.2% half year growth), Operator X will have 620,000 HSPA+ subscribers by the end of 2010, an increase from 575,000 subscribers as of June 2009. 3G/HSPA+ Subs Total Mobile Subs @ June 2009 3G subs @ Growth June 2010 End of 2010 Additional Subs June 2009 (GP assumption) 3G subs (Jun – Dec 2010) 2,000,000 500,000 15.0% 575,000 620,000 45,000 Prediction # 3: Additional Coverage Required As of June 2009, Operator X currently has 5,300 sectors (approximately 2,120 sites). For a more precise calculation, we make reference to sectors (as opposed to sites). This is because in Hong Kong, networks are not necessarily configured as 3 sectors per site. Due to the compact size of the country and limited space in between buildings, each site can be configured from S1/1 to S2/2/2/2/2/2. Based on the Predictions 1 and 2, to support an additional 45,000 from June – December 2010 (six months), Operator X would need to install an additional 415 sectors. The total cost of ownership (TCO) to deploy these 415 sites is estimated at approximately USD 24.4 million. Expected Revenue From the 45,000 additional subscribers Operator X expected to be acquired by end of 2010 at ARPU rate of HKD200/month, Operator X will gain a total revenue of HKD108 million/year (USD13.8 million/year). The question now is, is the expenditure of USD 24.4 million justified for an increase of 45,000 subscribers over a short period of six months? How much will Operator X need to spend over the next three years to improve its infrastructure and support subscriber growth? With ARPU’s declining rate versus large network upgrade costs, how will Operator X sustain in the long term? From an ROI perspective, with the investment expenditure of USD 24.4 million for 415 sectors, Operator X faces an ROI period of one year and nine months. This duration is based on the average growth pattern of subscribers. However, as data usage per user continues to rise through the use of data intensive applications, Greenpacket believes that the ROI on required infrastructure upgrades can extend to two or three years. This is a very risky approach as technologies evolve at a fast pace and infrastructure normally changes every five years, for example the evolution of from GSM-WCDMA-HSPA+ to LTE. 13 WHITEPAPER
  17. 17. Is There a Better Alternative? As opposed to expensive and time consuming network upgrades, it would be more cost and time efficient for Operator X to manage extra network workload by offloading to WiFi. This is an ideal alternative for Operator X in view of the excellent network of WiFi hotspots available in Hong Kong. With close to 9,0002 WiFi hotspots available, mathematically assuming, every km2 has an average of eight hotspots! By partnering with these WiFi providers, Operator X can support its growing subscriber base with involving time, effort and money on network upgrades. Additionally, as mentioned earlier, poor indoor reception is a major concern for mobile broadband operators. This issue can only resolved through indoor solutions such as WiFi. Hence, aside from managing data influx on their networks, WiFi help operators to improve indoor coverage remarkably. Offloading data to WiFi hotzones3 is also an approach undertaken by AT&T, a leading mobile network operator in the United States. AT&T began this project in May 2010 in New York City to supplement its mobile broadband in areas with high 3G traffic and mobile data use. Customer usage and satisfaction levels have been extremely encouraging according to Angie Wiskocil, Senior VP, AT&T WiFi Services. AT&T is in the midst of rolling out more WiFi hotzones to more cities in United States. Conclusion In the age of growing intensive data usage, celullar operators in developed markets need an immediate and cost-effective way to manage their networks. The proliferation of smartphones and decreasing ARPU levels further add urgency to ensure network congestion does not pose a threat. One of the solutions to prevent network congestion is by offloading data to alternative broadband networks, especially WiFi. Aside from balancing network bandwidth, WiFi is a good indoor solution and provides a much better reception compared to cellular networks.
