The functionality of a 256kbps broadband service
15 Both of the advertising campaigns in question involved the reduction or dethrottling of the speed of download to 256kbps after a certain volume of data was downloaded in each month (30GB in relation to the first advertising campaign, and 15GB in relation to the second advertising campaign).
16 The speed of download of data in a broadband service is measured by the number of pieces of information called bits which are transmitted each second. A speed of one kilobit per second is achieved when 1000 bits are transmitted each second. A speed of one megabit per second is achieved when 1,000,000 bits are transmitted each second.
17 On its website, to which reference is made in the first and third advertisements, the respondent explains that its broadband service operates at a maximum speed of 20 megabits per second. Further, 50 percent of its customers on the direct broadband network receive speeds of 8 to 20 megabits per second. Actual speeds might vary and might be slower. Many factors affect speed such as the distance of the customer from the telephone exchange, the condition of the customer's phone line, the hardware and software used by the customer, the source of the download, and the general level of internet traffic.
18 Part of the applicant's case was that the reduction in functionality from "super-fast" to 256kbps made it misleading and deceptive to describe the broadband plan offered as "unlimited".
19 Expert evidence was relied upon by both parties to establish the functionality of a broadband service operating at 256kbps. Dr John Ellershaw swore an affidavit filed on behalf of the applicant and Alan Hinds swore an affidavit filed on behalf of the respondent. In the result there was no significant disagreement between the experts on the relevant issues and neither was cross examined. Both were well qualified to give the evidence and their qualifications were not questioned.
20 Dr Ellershaw is an independent consultant who between 1987 and 2000 worked in senior positions in Telstra Limited. In the last five years he has been the Executive Director of the Centre for Ultra Broadband Information Services at the University of Melbourne. The Centre is a telecommunications research group working in the area of telecommunication networks and broadband issues.
21 Dr Ellershaw was asked by the solicitors for the applicant to address a range of popular internet usages in his report, namely, the use of You Tube, Facebook, video calling using Skype, television and music downloads, and ABC iView.
22 In relation to You Tube, he said that videos would replay as intended in an uninterrupted fashion at a download speed of 8mbps or above. At 256kbps a You Tube video would experience interruptions, stopping and starting regularly (except possibly at the lowest screen resolution) resulting in a lower quality viewing experience.
23 As to Facebook, Dr Ellershaw said that it performs as designed at 8mbps and above. At 256kbps, text exchanges in Facebook work as designed but standard sized photos take a few seconds to download instead of downloading in a fraction of a second.
24 In relation to video calling using Skype, Dr Ellershaw said that it would operate as intended in an uninterrupted fashion at a download speed of 8mbps or above. At a maximum speed of 256kbps Skype video calls might suffer jumpy motion with possible interruption to the sound. High quality Skype video calls might not work at all.
25 Dr Ellershaw said that an average length movie of 1.64GB would download in 27 minutes where the service operated at 8mbps, in 11 minutes where the service operated at 20mbps, and in 14 hours where the service operated at 256kbps. Further, high quality movies might take three times as long to download. A 50 minute recorded television show would take about 4 minutes to download at 8mbps and 100 seconds at 20mbps. At 256kbps a 50 minute television show would take over 2 hours to download.
26 In relation to music download, Dr Ellershaw said that individual songs would download in under a second at a speed of 8mbps or above. At 256kbps individual songs would take 20 or more seconds to download.
27 In relation to ABC iView, Dr Ellershaw said that recorded television shows would replay as intended in an uninterrupted fashion at a download speed of 8mbps or above. ABC iView would not work at 256kbps. Replays would pause regularly for significant periods resulting in a low quality viewing experience.
28 The respondent relied on the affidavit of Mr Hinds. Mr Hinds has been employed by the respondent since 1993 in a variety of technology and technical roles in the internet and data service areas. He has been Manager, IP and Data Services, Architecture Team for five years.
29 Mr Hinds produced a table of possible activities which can be undertaken on the internet. He then assessed the functionality of each of those activities when the broadband service was operating at 256kbps. The first category comprised uses where that speed would have little, if any discernible effect. In the second category were uses where that speed would allow use but at a "noticeably slower" speed. In the third category were uses where that speed would for all practical purposes not provide sufficient functionality to allow the relevant use, or only allow that use with a prolonged wait.
30 The first category contained 23 uses including such things as paying bills online, viewing online bank statements, checking bank account balances, purchasing groceries online, or using online dating services.
31 The second category contained 43 uses including accessing email, general browsing, conducting banking transactions online, accessing weather or maps, accessing real estate information, searching for jobs online, and accessing new or used car information.
32 The final category contained 10 uses including, downloading large software applications, playing complex games online, accessing streamed video news, making telephone calls via the internet such as by using Skype, accessing streamed video on You Tube, accessing streamed video sport, downloading television programs, downloading feature length movies, using streamed television such as ABC iView, and uploading video.
33 Not much significance should be placed on the raw numbers of uses which Mr Hinds allocates to categories one and two. There appears some inconsistency in Mr Hinds' categories, with the inclusion of uses in the first and second categories which could properly be described as general browsing, a use already included in the second category. Then online banking transactions are within the second category, even though some online banking activities, such as checking bank account balances and paying bills online are separately included in the first category. Further, there seems to be some duplication within the categories. For instance, online banking activities are split into separate activities namely, checking bank account balances, paying bills online and viewing online bank statements. Even allowing for the limitations in Mr Hinds' evidence, it provides a wider context for the consideration of the functionality of a broadband service offered at 256kbps by showing that there are functions which will operate satisfactorily at that speed, and functions which will be usable but noticeably slower.
34 Importantly however, both Dr Ellershaw and Mr Hinds agree that a service provided at the speed of 256kbps is practically unusable for downloading feature length movies, downloading television programs, streaming video such as You Tube, streaming television such as ABC iView and making video telephone calls using internet services such as Skype. In addition, Mr Hinds says that a broadband service at that speed is practically unusable for downloading large software applications and for playing complex games.
35 In accordance with this evidence I find that a broadband service supplied at the speed of 256kbps is practically unusable for downloading feature length movies, downloading television programs, streaming video such as You Tube, streaming television such as ABC iView and making video telephone calls using services such as Skype. In addition, I accept Mr Hinds' evidence that a broadband service at that speed is practically unusable for downloading large software applications and for playing complex games.
36 There was no research tendered in evidence which showed the extent of the usage of these functions by customers who purchased broadband services from the respondent. However, Dr Ellershaw's report accepts that these are popular uses, and Mr Hinds took no issue with that description. Additionally, the fourth advertisement expressly refers to using the broadband service to keep in touch, to download larger files, and to download movies. From this I infer that these uses are popular uses. Further, general knowledge of the community confirms that these uses are widely adopted ways of using a broadband service.
