But don’t worry, I have created this FREE ebook so you can familiarise yourself with the basics like 3G, 4G etc. Students & fresh graduates: If you are just starting, the complexity of the cellular industry can be a bit overwhelming. Whatever you are trying to do, here are some downloads that can help you: But sometimes, we need some extra support especially when preparing for a new job, or studying a new topic, or maybe just buying a new phone. Thank you for reading this post, I hope it helped you in developing a better understanding of cellular networks.
Drivers tacho symbols what does it mean download#
Mobile network technology symbols and expected peak and average download speeds. General Packet Radio Service – GPRS (GSM) Universal Mobile Telecommunications System-UMTSĮnhanced Data for Global Evolution – EDGE (GSM) SymbolĮvolved High-Speed Packet Access -HSPA+ (UMTS) We have also put the average speeds in this table to give you an idea however, please note that the average speeds vary considerably depending on which mobile network you are on and which location you are in. The table below shows which symbols relate to which network technologies and the maximum speeds for each of the technologies. When your phone is on a 2G (GSM) network, you will likely see the E symbol.
For example, if the 4G LTE technology serves your phone, it will either show a combination of LTE and LTE+ symbols or a combination of 4G and 4G+ symbols. Your mobile phone always indicates which type of mobile network technology you are connected to. Generally, depending on how many people are on the network and how far you are from the base station, you may only get to enjoy a small portion of this 384 kbps.Ī simplified overview of 1G, 2G, 3G, 4G and 5G Why does my phone say E instead of 4G? Even though 384 kbps can theoretically support basic mobile internet tasks, but we don’t get peak speeds in real life. The packets of data bursts are sent at different intervals for different users, making the overall process much more efficient.ĮDGE can offer peak downlink speeds of up to 384 kbps for downloads, which is more than double the speed that GPRS can offer.
With EDGE, the capacity available on the packet-switched part of the network is shared among multiple users. GPRS later evolved into EDGE, which offered much higher speeds to users when browsing the internet from their phones.
As you can imagine, that was not efficient, which led to introducing a packet-switched technology called GPRS or General Packet Radio Service to address the data part. However, the technology was circuit-switched, which meant that it required a dedicated circuit to carry out the data sessions for each user. When GSM networks were originally launched, they had a technology that allowed mobile users to access the internet from their mobile phones. Average speeds you can expect when served by 2G GSM EDGE networks.
