Previous Generation Networks Vs 5G
In this article, we will compare previous generation networks Vs 5G. There has been a hype of lofty promises and a lot of controversies ongoing around the rollout of the new 5G wireless technology. Without a grasp of the underlying facts and principles, it’s easy to urge trapped within the hype.
The Issue of Generations, First of all, the “G” in 5G and other network classifications stands for “Generation.” Each generation of wireless broadband is assessed and supported with a gaggle of telephone network standards that describe the technical implementation of the system. Under this category, 2G refers to the second generation of mobile networks which supports GSM – the worldwide System for Mobile, a world standard for mobile phones. Radio signals used under the primary generation or 1G network were analogue, while 2G networks were digital and duologue. By allowing multiple users on one channel via multiplexing, 2G networks enabled cellular phones to figure out with both data and voice.
In debating the comparison of 2G vs 5G, it’s necessary to see that at the systems from two standpoints: As that of wireless frequency and therefore, the performance of their broadband / cellular networks. From a frequency perspective, 2G and 5G have two .4GHz and 5GHz (gigahertz) wireless frequencies, respectively. And the main differences between the 2 frequencies is that it dwells the range (i.e., coverage) and bandwidth (i.e., speed) that the bands provide. The 4GHz band provides coverage at an extended range, but can only transmit data at slower speeds. In contrast, the 5GHz band provides less coverage but transmits data at faster speeds. So 5GHz provides faster data rates at a shorter distance, while 2.4GHz offers coverage over farther distances, but may perform at slower speeds. Higher frequencies dissipate or dissolve more quickly and have more difficulty penetrating solids. For this reason, the 5GHz band has difficulty passing through solid barriers like walls and floors.
Meanwhile, the 2.4GHz band is restricted by regulatory domains to only 11 channels, only three of which don’t overlap. The 5GHz band operates over 23 channels, all of which are non-overlapping. Since overlapping channels distort radio signals, devices using them often get to retransmit data packets, which slows down their performance. When multiple devices plan to use an equivalent radio space, overcrowding occurs. This problem is far less severe with the 5GHz band thanks to its greater number of non-overlapping channels and therefore the incontrovertible fact that fewer devices actually use it. \Note that 5GHz Wi-Fi isn’t 5G cellular, which utilizes the rarely used radio millimetre bands within the 30GHz to 300GHz range but 5GHz Wi-Fi is a short-range home networking system that operates within the 5GHz radio band. At the 2GHz level, cordless phones, microwaves, and various other home devices use or transmit radio frequencies inside the two .4Ghz range.
For 2G cellular, data speeds of up to 64kbps (kilobits per second) are possible, over a bandwidth of 30 to 200KHz (Kilohertz). At the time of its launch, this allowed for better quality voice calls than were available under the primary generation of mobile phones. It also enabled services like SMS (Short Message Service) and MMS (Multimedia Message Service).
