Deal: 73% off 2-year plans + 3 extra months ]
- Meshnet Feature for Personal Encrypted Networks: NordVPN offers a unique feature called Meshnet, which allows users to connect their devices directly and securely over the internet. This means you can create your own private, encrypted network for activities like gaming, file sharing, or remote access to your home devices from anywhere in the world.
- RAM-Only Servers for Enhanced Security: Unlike many VPN providers, NordVPN uses RAM-only (diskless) servers. Since these servers run entirely on volatile memory, all data is wiped with every reboot. This ensures that no user data is stored long-term, significantly reducing the risk of data breaches and enhancing overall security.
- Servers in a Former Military Bunker: Some of NordVPN's servers are housed in a former military bunker located deep underground. This unique location provides an extra layer of physical security against natural disasters and unauthorized access, ensuring that the servers are protected in all circumstances.
- NordLynx Protocol with Double NAT Technology: NordVPN developed its own VPN protocol called NordLynx, built around the ultra-fast WireGuard protocol. What sets NordLynx apart is its implementation of a double Network Address Translation (NAT) system, which enhances user privacy without sacrificing speed. This innovative approach solves the potential privacy issues inherent in the standard WireGuard protocol.
- Dark Web Monitor Feature: NordVPN includes a feature known as Dark Web Monitor. This tool actively scans dark web sites and forums for credentials associated with your email address. If it detects that your information has been compromised or appears in any data breaches, it promptly alerts you so you can take necessary actions to protect your accounts.
The pandemic made it clear that the millions of homes with no broadband or poor broadband were cut off from taking the office or the school home. But the pandemic also showed many additional millions of homes that their current ISP connection isn’t up to snuff for working or doing schoolwork from home. Families often found that multiple adults and students couldn’t share the bandwidth at the same time.
The simplest explanation for this is that homes were suddenly expected to connect to a school or work servers, use new services like Zoom, or make telemedicine connections to talk to doctors. These new requirements have significantly different bandwidth needs when a home’s big bandwidth need was watching multiple video streams at the same time. Consider the following bandwidth needs listed by Zoom:
Zoom says that a home should have a 2 Mbps connection, both upload and download, to sustain a Zoom session between just two people. The amount of download bandwidth increases with each person connected to the call, meaning Zoom recommends 6 Mbps download for a meeting with three other people.
Telemedicine connections tend to be even larger than this and require the simultaneous use of both upload and download bandwidth. Connections to work and schools servers vary in size depending upon the software being used, but the VPNs from these connections are typically as large or larger than the Zoom requirements.
Straight math shows fairly large requirements if three or four people are trying to make these same kinds of 2-way simultaneous connections at the same time. But houses are also using traditional bandwidth during the pandemic like watching videos, gaming, web browsing, and downloading large work files.
The simplistic way to look at bandwidth needs is to add up the various uses. For instance, if four people in a home wanted to have a Zoom conversation with another person, the home would need a simultaneous connection of 8 Mbps both up and down. But bandwidth use in a house is not that simple, and a lot of other factors contribute to the quality of bandwidth connections within a home. Consider all of the following:
- WiFi Collisions. WiFi networks can be extremely inefficient when multiple people are trying to use the same WiFi channels at the same time. Today’s version of WiFi only has a few channels to choose from, and so the multiple connections on the WiFi network interfere with each other. It’s not unusual for the WiFi network to add a 20% to 30% overhead, meaning that collisions of WiFi signals effectively waste usable bandwidth. A lot of this problem is going to be fixed with WiFi 6 and 6 GHz bandwidth which together will add a lot of new channels inside the home.
- Lack of Quality of Service (QoS). Home broadband networks don’t provide quality of service, which means that homes cannot prioritize data streams. If you were able to prioritize a school connection, then any problems inside the network would affect other connections first and would maintain a steady connection to a school. Without QoS, a degraded bandwidth signal is likely to affect everybody using the Internet. This is easily demonstrated if somebody in a home tries to upload a giant data file while somebody else is using Zoom—the Zoom connection can easily drop temporarily below the needed bandwidth threshold and either freeze or drop the connection.
- Share Neighborhood Bandwidth. Unfortunately, a home using DSL or cable modems doesn’t only have to worry about how other in the home are using the bandwidth, because these services used shared networks within neighborhoods, and as the demand needs for the whole neighborhood increase, the quality of the bandwidth available to everybody degrades.
- Physical Issues. ISPs don’t want to talk about it, but events like drop wires swinging in the wind can affect a DSL or cable modem connection. Cable broadband networks are also susceptible to radio interference—your connection will get a little worse when your neighbor is operating a blender or microwave oven.
- ISP Limitations. All bandwidth is not the same. For example, the upload bandwidth in a cable company network uses the worse spectrum inside the cable network—the part that is most susceptible to interference. This never mattered in the past when everybody cared about download bandwidth, but an interference-laden 10 Mbps upload stream is not going to deliver a reliable 10 Mbps connection. There are a half dozen similar limitations that ISPs never talk about that affect available bandwidth.
The average home experiencing problems when working at home during the pandemic is unlikely to diagnose the reasons for the poor bandwidth fully. It is fairly obvious if you have problems with having multiple zoom connections if the home upload speed isn’t fast enough to accommodate all connections. But beyond the lack of broadband capacity, it is not easy for a homeowner to understand any other local problems affecting their broadband experience. The easiest fix for home broadband problems is for an ISP to offer and deliver faster speed since excess capacity can overcome many of the other problems that might be plaguing a given home.
Ideal for bandwidth is for each participant of a meeting to have just a single bi-directional A/V session to a central server running on a very high speed link (handling perhaps 30+ streams for crowded school classes). That then leads to privacy issues since the server will be working with the clear A/V streams, unless schools and businesses do it themselves. But, can they? Maybe we can use some social-distancing online.
