Latency Explained: A Guide for Nonprofit Leaders in Digital Access

Overview

This guide explains the concept of internet latency specifically for nonprofit organizations and digital equity advocates working to bridge the digital divide in underserved, rural, and low-income communities. It highlights why low latency is crucial for modern applications like video calling, remote education, and digital navigation, and offers actionable strategies for community-centered internet deployment.

What is Latency?

Latency is the delay or lag time it takes for data to travel from your device to its destination (such as a server or website) and back, typically measured in milliseconds (ms). While bandwidth measures how much data can be sent at one time, latency measures how fast that data actually travels. In simpler terms, if bandwidth is a highway's number of lanes, latency is the speed limit and the flow of traffic; even on a wide highway, your journey will feel slow if there are severe delays.

Why Latency Matters for Nonprofit Leaders in Digital Access

For nonprofit leaders in digital access and inclusion, understanding latency is vital because digital equity is about quality of connection, not just basic access. When helping underserved households, providing high-bandwidth plans that suffer from high latency can still render critical services like remote schooling, job hunting, and telemedicine entirely unusable. Digital navigators and local advocates must understand that a connection with high working latency (latency under load) will constantly drop video calls or lag during interactive tasks, undermining the digital equity initiatives they work so hard to fund and implement.

Practical Examples

Consider a community center in an isolated Appalachian town where a local nonprofit installed a low-latency internet solution. During an emergency, staff used the connection to communicate in real-time with emergency services, saving a community member's life. In another scenario, a nonprofit partnering with a housing authority deployed low-latency millimeter-wave technology to connect hundreds of low-income families. Instead of children experiencing severe buffering and dropped video feeds during online homework, the stable low-latency connection allowed multiple family members to attend virtual classes and apply for employment simultaneously without disruption. Lastly, digital navigators setting up local community-centered networks utilize low-latency wireless backhaul to run telehealth kiosks that require immediate, real-time responses from doctors.

Tips for Evaluation or Improvement

Nonprofits can evaluate and improve internet experiences through several key actions:

1. Promote local peering and edge hosting: Advocate for the establishment of carrier-neutral Internet Exchange Points (IXPs) in your region, keeping local data local and dramatically reducing latency.
2. Prioritize low-latency technologies: When funding or implementing networks, prioritize fiber, millimeter-wave (mmWave), or modern Low Earth Orbit (LEO) satellites over older copper or geostationary satellite connections.
3. Train Digital Navigators on working latency: Ensure your staff and digital navigators measure latency under active network load during community speed tests to accurately diagnose performance issues.
4. Audit local equipment: Often, outdated routers and switches in community labs create bottlenecks. Upgrading to equipment with modern queue management (to prevent bufferbloat) can improve latency without needing a more expensive ISP plan.

Common Challenges

Nonprofit digital access leaders regularly face structural obstacles when dealing with latency. Traditional providers frequently overlook underserved areas, leading to infrastructure gaps that result in higher latency. Many remote regions rely on geostationary satellite services, which inherently suffer from high latency due to the extreme physical distance signals must travel. High-performance cloud data centers are usually situated in affluent urban hubs, creating a geographical digital divide where rural and marginalized communities must send data across much longer distances, degrading real-time performance. Furthermore, legacy copper networks and outdated localized routing mean data takes highly inefficient detours before reaching its destination, raising costs and worsening latency.

Quick FAQ

Q: Is a fast speed test speed (bandwidth) the same as low latency?
A: No. Bandwidth is how much data can move at once, while latency is the speed of round-trip travel. A high-bandwidth satellite connection can still feel sluggish and lag during live video calls due to high latency. Q: What is a "good" latency measurement?
A: Ideally, latency should be under 50 milliseconds (ms) for seamless interactive applications. Latency over 100ms often causes noticeable delay in video calls and online systems, and geostationary satellites can exceed 500ms. Q: What is "latency under load" or "working latency"?
A: This measures latency when your network is actively being used (e.g., when someone is downloading a large file). A network that performs well when idle may suffer from severe "bufferbloat" and lag when multiple devices are active. Q: How can we measure latency on our community network?
A: Run an online speed test that specifically displays "Loaded" and "Unloaded" latency, or use command-line tools like "ping" to measure the latency to common public servers.

Checklist for Implementation

1. Measure Current Latency: Run a speed test during peak usage times to record your organization's ping (latency) and jitter.
2. Review Digital Service Needs: Audit your programs (e.g., telehealth, live-streamed tutoring, or VoIP hotlines) to determine if your activities require low-latency performance (under 50-100 ms).
3. Evaluate Connection Types: Compare your current setup (such as high-latency GEO satellite or poor-quality fixed wireless) against low-latency options like fiber, cable, or low-Earth orbit (LEO) satellite services.
4. Establish "Buffer-Friendly" Workarounds: Implement edge caching, offline-first digital resources, or asynchronous alternatives for community members struggling with high-latency connections.
5. Upgrade Internal Hardware: Ensure your routers are running the latest firmware and switch critical desktop devices from Wi-Fi to wired Ethernet connections to shave off internal network lag.
6. Negotiate Service Level Agreements (SLAs): When contracting with internet service providers (ISPs) for community centers or digital hubs, advocate for latency and jitter metrics in your contracts.
