As a communications expert with a focus on mobile data technologies, I can provide a detailed explanation of 2G data speeds. The second generation of mobile telecommunications, commonly referred to as 2G, was a significant leap forward in terms of data capabilities compared to its predecessor, 1G. This generation introduced digital communication, which allowed for more efficient use of the available spectrum and paved the way for mobile data services.

General Packet Radio Service (GPRS) is a packet-oriented mobile data service available to users of 2G and 3G mobile communications. It is considered the first standard for wireless data communication and was introduced to the market in the year 2000. GPRS allows for the transfer of data in packets rather than a constant stream, which is more efficient for bursty data usage patterns such as email and web browsing.

The theoretical maximum transfer speed of GPRS is 171.2 kbit/s, but this is under optimal conditions and with a single time slot. In practice, the speed is significantly lower due to various factors such as network congestion, signal strength, and the number of time slots available to a user. Typically, users can expect speeds around 50 kbit/s, and in some cases, it may be as low as 40 kbit/s.

**Enhanced Data Rates for GSM Evolution (EDGE)** is a radio modulation technique that is part of the 2.5G and 3G mobile telecommunications standards. It is an improvement over GPRS and offers higher data rates by using more efficient modulation schemes. EDGE is often referred to as "2.75G" because it bridges the gap between 2G and 3G technologies.

The theoretical maximum transfer speed of EDGE is 384 kbit/s with a single time slot. However, in practice, the speed is often much lower. The speeds can range from 100 kbit/s to 200 kbit/s, depending on the network conditions and the number of time slots available. It is important to note that EDGE is not a true 3G technology but rather an enhancement to 2G that allows for better data rates.

When comparing these speeds to modern standards, it's clear that 2G data speeds are quite slow by today's standards. For instance, 4G LTE networks offer theoretical maximum speeds of up to 1 Gbit/s, and 5G networks are expected to offer peak speeds of up to 20 Gbit/s.

In summary, while 2G technologies like GPRS and EDGE were revolutionary at the time of their introduction, they are now considered outdated compared to the high-speed data capabilities of 3G, 4G, and 5G networks. Users relying on 2G networks today would find the speeds to be significantly slower than what is available on modern networks, making it unsuitable for data-intensive applications such as video streaming, online gaming, and large file downloads.
