s about WiFi from a fake source
Hey there! I'm a curious teen trying to understand something big. The question is about why internet speeds aren't always fast enough, even though it seems like it should be. People wonder if cost or complicated work makes it hard for ISPs to improve everywhere. It's frustrating to think about how much effort goes into making the internet work for everyone!
Since profit drives everything, they won’t speed things up without competition. Gigabit needs fibre optic cables, which are costly. Most firms avoid spending if an existing solution suffices. The price isn’t just the cable—it includes hiring staff to install it. If there’s no demand or a tiny user base, they’ll ignore it and treat it as a low-priority opportunity.
It’s usually not just the WiFi that limits your connection; often it’s the outdated internet cables that were never meant for high-speed internet. To achieve gigabit speeds, you’d need to lay new fiber-optic lines, which is costly. This also raises profit concerns. Running old copper cables isn’t enough if people want faster access.
The key point to remember is that ISPs don’t control your Wi-Fi connection. They only supply the internet to your home, after which you’re responsible for managing it. While some ISPs might offer poor Wi-Fi options, they aren’t obligated to provide anything specific.
Gigabit doesn't need fiber directly to the location. It's definitely a top option, but you can achieve gigabit speeds using coaxial cables too. However, that still demands significant changes to existing infrastructure. When ISPs don't have enough competition to push these upgrades, they often ignore them. Coax with DOCSIS 3.1 or the newer DOCSIS 4.0 can reach 10Gbps and support bidirectional speeds, allowing you to get 1000/1000 performance instead of the typical 1000/40 speeds most providers offer over coax.
If you're curious about why ISPs struggle to provide gigabit speeds at your location, it relates to how copper wires work. The amount of data they can handle depends on bandwidth, which is essentially the range of frequencies used. Copper cables can carry as little as 0Hz for DC power, meaning their bandwidth ranges from zero up to a maximum frequency. This maximum frequency is limited because copper behaves like a low-pass filter—higher frequencies get weakened more, eventually making it impossible for receivers to interpret them. The upper boundary also gets affected by the cable length; shorter runs allow higher speeds, while longer ones restrict bandwidth and speed. Fiber optic cables avoid this issue since they function differently as wave guides, enabling much greater bandwidth over extended distances. In short, the constraints are tied to both frequency limits and physical distance.
ISPs aren't responsible for establishing WiFi protocols. The WiFi association along with IEEE define the rules. Additionally, authorities play a role in allocating spectrum for use. For instance, 2.4 and 5 GHz bands don’t need official permission to operate as long as usage complies with regulations. This is why numerous wireless gadgets rely on these frequencies. Governments also determine maximum transmission power limits. Consequently, performance is largely constrained by these rules. Most ISPs employ routers and modems in a single unit. These units often face challenges like overheating or insufficient processing power to manage heavy traffic. They depend on such equipment because it provides standardized hardware that technicians can support with troubleshooting. It’s important to recognize that WiFi and the internet are distinct concepts. Many people struggle to differentiate between them. You might access Wi-Fi without an internet connection, using it solely for local network tasks. Regarding the internet side, ISPs can improve services but aren’t obligated to do so. Why? Because they profit from excessive usage. Fiber optics remain costly in sparsely populated regions since profitability depends on density. Even cable internet (coaxial) relies on fiber connections at each node, and with DOCSIS 3.1, additional fiber is required as distance shrinks. Coax offers lower installation costs but has limitations. Unlike DSL, coax signals can be boosted, which most providers achieve by amplifying. However, companies such as Comcast are adopting a Node-to-Node strategy—expanding fiber and nodes while reducing amplifier use. This results in shorter signal reach but potentially less congestion and faster speeds. If you’re tied to an older DSL connection, it likely falls short of what current FCC standards define as high-speed internet. While vDSL offers better performance, it generally caps speeds around 100 Mbps. We’re approaching the limits of traditional phone lines, yet providers continue pushing for more capacity.
