Number of services in operation by download data rate. Table iv. Number of services in operation by state or territory excluding satellite. Table v. Number of services in operation by POI classification excluding satellite. September Market Indicators report. See also: Previous reports.

Read the latest media release accompanying the current report. Chart 11 below shows the corresponding median upload speeds. The median upload speed for this period across all consumers was 14 Mbps. Chart 11 : Median upload speeds by ISP. As seen in the chart, the median download speeds for DSL and satellite technologies, which are both 16 Mbps, lag the median download speeds for cable and fiber technologies which are respectively 97 and 73 Mbps.

Similarly, the median upload speeds for DSL and satellite technologies, which are respectively 2 to 3 Mbps, lag the median upload speeds of cable and fiber technologies which are respectively 11 and 82 Mbps. Observing both the download and upload speeds, it is clear that fiber service tiers are generally symmetric in their actual upload and download speeds.

This results from the fact that fiber technology has significantly more capacity than other technologies and it can be engineered to have symmetric upload and download speeds. For other technologies with more limited capacity, higher capacity is usually allocated to download speeds than to upload speeds, typically in ratios ranging from to Chart 12 : Median download and upload speeds by technology. Chart 4 in Section 2.

Charts Chart As noted, median speeds experienced by consumers may vary based on location and time of day. Chart 14 below shows the corresponding percentage of consumers whose median upload speed fell in each of these ranges. Even though the median upload speeds experienced by most subscribers were close to or exceeded the advertised upload speeds there were some subscribers, for each ISP, whose median upload speed fell significantly short of the advertised upload speed.

On the other hand, ISPs using cable and fiber technology generally showed very good consistency based on this metric. We can learn more about the variation in network performance by separately examining variations across geography and across time. For each ISP, we first calculate the ratio of the median download speed over the peak usage period to the advertised download speed for each panelist subscribing to that ISP.

For each ratio of actual to advertised download speed on the horizontal axis, the curves show the percentage of panelists subscribing to each ISP that experienced at least this ratio. The curves for cable-based broadband and fiber-based broadband are steeper than those for DSL-based broadband and satellite-based broadband. This can be seen more clearly in Chart All actual speeds discussed above were measured during peak usage periods. In contrast, Charts The ratio is lowest during the busiest four-hour time block p.

For each ISP, Chart 6 in section 2. Chart 19 below shows the weighted median latencies, by technology and by advertised download speed for terrestrial technologies. For all terrestrial technologies, latency varied little with advertised download speed. DSL service typically had higher latencies than either cable or fiber. As shown in Charts However, the ratio of median download speed to advertised download speed varies among service tiers.

It should be noted that for Verizon-DSL, which advertises a range of speeds, we have calculated a range of values corresponding to its advertised range. Table 2 lists the advertised download service tiers included in this study. As in past reports, we note that the download speeds listed here are based on national averages and may not represent the performance experienced by any particular consumer at any given time or place.

Table 2: Peak period median download speed, sorted by actual download speed. Download Median Speed Mbps. Advertised Download Speed Mbps. In Section 3. C above, we presen0ted speed consistency metrics for each ISP based on test results averaged across all service tiers. Consistency of speed is important for services such as video streaming.

A significant reduction in speed for more than a few seconds can force a reduction in video resolution or an intermittent loss of service. Similarly, Charts C above, we presented complementary cumulative distributions for each ISP based on test results across all service tiers. Below, we provide tables showing selected points on these distributions by each individual ISP. Overall, performance depended less on a specific technology and more on the engineering and marketing choices made by each provider.

Below, we provide the detailed results of the webpage download time for each individual service tier of each ISP. Generally, website loading time decreased steadily with increasing tier speed until a tier speed of 15 Mbp,s and does not change markedly above that speed.

In order to avoid confusion between the date of release of the report and the measurement dates we have shifted last year to numbering the reports. Going forward we will continue with a numbered approach and the next report will be termed as the Ninth Report. The median is that value separating the top half of values in a sample set with the lower half of values in a sample set; it can be thought of as the middle value in an ordered list of values.

For calculations involving multiple speed tiers, we compute the weighted average of the medians for each tier. The weightings are based on the relative subscriber numbers for the individual tiers.
