ki kell dobni az osszes ketutemu motort, mikor a benyakuton mar nem arultak tobbe keverek benyat! janem :D ugyanaz a helyzet. hal'istennek azert lassankent csak kikoptak a 2-stroke-ok. :) aki meg oldtimerkedni akar, vagy kell a sti'lfu"re'szbe (lassan azok kozul is kikopnak a 2T-k), az kavar maganak.
a "senki altal nem kert 5G" pedig:
- Network architecture: If you’ve ever experienced slow internet in a crowded apartment building, then you understand the importance of bandwidth. The reason your internet seems to crawl when your neighbor is on a Zoom call is that on a network, all devices share bandwidth. So, if one device is using a lot of data, there’s an effect on all devices trying to send and receive data. 4G network architecture simply can’t support the ever-increasing number of devices attempting to share bandwidth, which is where 5G comes in. Unlike 4G networks, 5G network architecture is designed to carry information through the air across different frequencies: low band, mid band, and high band. High-band frequencies (called mmWave) can carry much more data in dense urban areas, meaning that a greater number of devices can connect at the same time without bringing down speeds. However, mmWave is impacted by physical barriers, such as walls and buildings, so 5G also balances issues with speed and range by using mid-band frequencies. Low-band capabilities help signal travel farther—over hundreds of square miles. This advanced architecture means that 5G provides better coverage for more devices.
- Speed and latency: The difference between bandwidth, speed and latency can be a little confusing. While bandwidth refers to the highest potential download rate of your network, speed is the actual rate at which things are downloading. Latency is the amount of time it takes your device to upload and download data. And while 4G networks made it possible to watch Netflix on our TVs while scrolling through videos on our phones, it’s 5G that will likely mean the end of buffering forever. 4G LTE speeds peak at about 100 Mbps. Though 5G speeds are affected by things like network congestion, location, time, carrier, and the distance from the nearest cell tower, 5G is usually a whopping 10 times faster than 4G and could one day be 100 times faster. In other words, it would take nine minutes to download an 8K movie on a 4G LTE network offering speeds of 30 Mbps. That same movie would only take about 16 seconds to download on a 1 Gbps 5G network.
- Energy efficiency: While most coverage of 5G networks focuses on speed, one unsung advantage of 5G over 4G is its environmental impact. Conserving energy is an important way to decrease carbon emissions, and widespread adoption of 5G will have a significant impact on emissions and energy usage. According to climate experts2, when using 4G, it takes one kilowatt-hour (kWh) of electricity to download 300 movies. With 5G, it takes the same amount of energy to download 5,000 ultra-high-definition movies. And as more homes begin to integrate smart appliances, decreasing energy consumption through 5G will likely become even more important.
- Coverage and connectivity: 4G coverage has definitely widened the coverage area of earlier generations—but it can still face challenges in rural areas and indoors. With 5G, coverage and connectivity is becoming much wider and more reliable. That’s because 5G utilizes a wider range of frequency bands than 4G, including mid-band and higher frequency bands such as mmWave. These bands make it possible to provide better coverage to densely populated areas and beyond.
