Welcome to the first installment of Preseem’s Know Your WISP Network blog series! This series of blogs will use the detailed metrics contained within Preseem’s latest Fixed Wireless Network Report. Our report leverages Preseem’s extensive data set of hundreds of real-world deployments across ISPs. While these insights can be applied to benchmark your business against the wider broadband ecosystem, they can also be used to attain a better understanding of the world of fixed wireless subscribers, networks, and equipment.

 

We begin our exploration of all-things fixed wireless by examining a high level overview of the WISP subscriber experience. To do this, we will examine fixed wireless subscriber insights that answer the following questions:

  • What is the average vs. peak download throughput for a typical fixed wireless subscriber?
  • How does the latency for a fixed wireless subscriber compare at peak vs other times of the day?
  • What is the average daily download usage for a typical fixed wireless subscriber?

Fixed Wireless Subscriber Insights: Download Throughput Data


Throughput refers to the network capacity (in bits/sec) received or sent by each active subscriber at an indicated time period. Put simply, upload throughput is the rate/speed at which users send data across the internet. Conversely, download throughput is the rate/speed at which users receive data from the internet. The figure below compares the download throughput achieved by WISP subscribers during the busiest (peak time) against other times of the day.

We can see that the difference between peak and off peak is surprisingly small. This indicates that, on the whole, subscriber throughput does not degrade significantly during busier times. It is also apparent that the average fixed wireless internet subscriber uses a little over 3 Mb/s of data during peak times, compared to almost 4 Mb/s during other times. The 95th percentile demonstrates a complementary result, with subscriber download throughput during peak times (11.0 Mb/s) being slightly less than during other times (11.4 Mb/s).

These results imply that WISP networks are not heavily oversubscribed. This means that such networks can handle periods of congestion with relatively low degradation in subscriber’s QoE. 

 

 

Fixed Wireless Subscriber Insights: Latency Data


Latency is one of the most important metrics when it comes to QoE, as subscribers feel its effects immediately. Latency contributes to common nuisances, such as dropped calls, continuously buffering video, and web pages that constantly lag. To measure latency,
Preseem tracks the round trip time for individual TCP segments in the access network. This approach results in thousands of latency samples per second, per subscriber. Preseem’s approach is fundamentally different than an ICMP ping-based latency measurement. This is because Preseem measures true end-to-end latency, including the latency in subscribers’ homes. The figure below compares the latency experienced by subscribers during the peak time against other times of the day.

It is apparent that the difference in latency that occurs during peak and off-peak times is quite small. For example, looking at the latency within the 80th percentile, we can see that peak time latency hovers at 77.5ms. For all times, that number lies in the 70ms range. Not only is the difference between peak and off-peak times minimal, but these numbers also constitute “acceptable” latency values, as agreed upon by most network operators. Additionally, the small difference in latency between peak and off-peak times supports the notion that WISP networks are not heavily oversubscribed.

An important note: Preseem collects these metrics from networks that utilize the Preseem platform to optimize latency and subscriber experience. Therefore, the latency experienced by subscribers in networks without such optimization is likely significantly higher.

 


Fixed Wireless Subscriber Insights: Usage Data


Subscriber usage refers to the total number of bytes transferred by a WISP subscriber over a given day or month. When considering a subscriber’s QoE, knowledge of the total usage for a period is not very informative. This is because consuming a large amount of data during off-peak times is less impactful to perceived network quality than is using a small amount of data during peak times. We have found that the average WISP subscriber download usage is 6.6 GB/day, or 196 GB/month. However, considering just the overall average disregards the significant variation of data usage that occurs between individual subscribers. As such, the
figure below shows the proportion of subscribers that download a particular amount of data per day. 

The individual usage amounts present a more interesting and comprehensive view of subscriber data usage than the overall average of download usage does. For instance, we can see that just over 33% of subscribers download less than 1 GB of data per day, while over 11% of subscribers download more than 16 GB of data per day. This disparity, between low data users and high data users, is fairly significant, and reaffirms the notion that WISPs should offer different data plans tailored to different subscriber needs.
