Email ID. Contact No. Hence bandwidth does not affect the performance of the system. UMTS is a cellular technology that transfers data with the help of packets. Radio technology is not used, and hence efficiency cannot be offered in the system as much as that of WCDMA. Radio technology is used in the system, and hence communication is done between two devices as an interface is used in the system. This makes the system more efficient and does not make any issues while transferring data.
This is one of the popular air interfaces used in mobile devices. This is an upgrading of CDMA where very less speed is used as per the standard. This can be utilized for the data in the system. If you are interested in device categories, have a look at this page from 3GPP , which is a few years old but outlines the concept. Basically, the higher the device category, the better speed you can expect as long as you are on the advanced LTE technology type.
LTE can enable peak download speeds of up to Mbps and peak upload speeds of up to 75 Mbps. The average download speed of LTE is around 15 to 20 Mbps. Have a look at our dedicated post on the difference between LTE and LTE Advanced but generally, the most noticeable difference for you as a mobile phone user may be the download and upload speeds.
With newer devices, i. For completeness, other factors like distance between the phone user and the base station and obstacles like buildings, trees, mountains, thick walls etc. Non-standalone 5G is the most common 5G network deployment at the moment, which relies on 4G and 5G networks both to offer 5G. You may also check out our dedicated post on 5G mobile networks. Thank you for reading this post, I hope it helped you in developing a better understanding of cellular networks.
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. Whatever you are trying to do, here are some downloads that can help you:.
You can then read Mobile Networks Made Easy which explains the network nodes e. Professionals: If you are an experienced professional but new to mobile communications, it may seem hard to compete with someone who has a decade of experience in the cellular industry. But not everyone who works in this industry is always up to date on the bigger picture and the challenges considering how quickly the industry evolves. So if work in sales, marketing, product, project or any other area of business where you need a high-level view, Introduction to Mobile Communications can give you a quick start.
Also, here are some templates to help you prepare your own slides on product overview and product roadmap. This employed packet switching which increased the speeds to a greater extent. UMTS employed wideband wireless network that increased the call quality. With the advent of UMTS architecture we are able to send large email messages and other required capabilities over the network quite easily. We see a phenomenal increase in the data rates compared to 3G.
With the advent of LTE greater support for interactive multimedia, audio and the video is achieved. We can see that with high speed there is also, high capacity and the marginal cost when compared to legacy standards are also much lower.
NodeB suggests a telecommunication Node in a particular mobile or cellular network. Node B provides the communication between the Ues which can be mobile phones and wider telephone network with enhanced quality of data and voice services.
The radio frequency transmitters that are present in the NodeB can be used to communicate directly mobile devices that move freely. It is the hardware that is connected to the mobile phone network, which can be used to communicates easily with the UEs. Handoff One of the major accepts of any telecommunication network is the handover from one cell tower to another. Here it is made sure that at least there is one radio link active for the UE. LTE does not employ soft handover because it employs OFDM architecture where the communication is through frequency divisions.
