Compare and contrast 3G wireless networks to 4G networks in terms of:
Network architecture
User perceptions

Today 3G wireless networks and 4G networks are used as the standards for mobile communication. Used most commonly in smartphone devices. They are both sufficient but they run differently. Comparing 3G networks to 4G networks is like comparing standard television to high depth television. They both work but one can work better depending on the viewer who is using it. All different carries are complaint with 3G networks including WCDMA, EV-DO and HSPA. The 4G networks are known as LTE, WiMax and UMB (DIFFERENCE btw 3G & 4G). The service and application between the two are very ...view middle of the document...

4 Mbps with peak download speed of up to 3.1 Mbps. On a 4G network the average download speed is 3-6 Mbps with peak download speed of more than 10 Mbps” (What is, 2012). The speed differance will push a user to the 4G of the 3G just because it runs faster. The speed is also the differance between the data throughput.
As user perception the 3G is always being used because the 4G is not offered coverage in every city so everyone is not getting to us the 4G coverage. However, when using the 4G coverage users can see the differance in speed and service. The 3G will continue to be more reliable unto the 4G can become accesable in every location like the 3G at this day in time.
Distinguish between the 4G LTE, 4G WiMax, and 4G WiBro networks based on:Upload and download speeds,User perceptions,Backward compatibility, Service availability
When trying to distinguish between the 4G LTE, 4G WiMax and 4G Wibro networks it can be very complex. One thing to keep in prospective is that each are similiar by providing ways to connect to a wireless network for workstation communiction or internet access. Also that each can be seen as improvement from the previous network (Black, 2012). “WiMAX, short for Worldwide Interoperability for Microwave Access, is a different standard known as the 802.16. It allows only so many users on the standard and then will cut off any additional users trying to use the connection. WiBro™, which stands for Wireless Broadband, is very similar to WiMAX. The transmission speeds are much the same, but the main difference is that WiBro™ can track a receiver that is moving from place to place” (Black, 2012). The Wibro work as long as the receiver stays within range. In regards to the Wimax it does not offer moility, so it need to be stationary to in order to receive a signal.
The LTE which stands for long-term evolution, which is known to be the fasters at this time. The LTE is slightly more affected by the number of users than Wimax (Newth, 2012). In a users percetion know the difference in how these standards work with their current and future buy it smartphones is critical. At this time Wibro is still a working process, the LTE is made for existing mobile and broadband deployments to were as the Wimax is made to work with new deployments (Newth, 2012). A user may want to consider a phone service that can off all three or at least two of th 4G standards in deciding which will be work better for them depending on the usage and what they are using the phone for.

The upload and download speed of the LTE is “up to 100 Mb/s downlink and 50 Mb/s uplink. The Mobile Wimax offers speeds of up to 30Mb/s”(What is the differeance, 2009). The Wibro...
