Compare and Contrast 3G Wireless Networks to 4G Networks
3G networks allow people to have high speed access to data and voice services, they are essentially a high-speed mobile Internet, that can offer speeds of up to 3.1 megabits per second (Mbps) or more. This speed is around the same speeds offered by earlier sellers of cable modems. However, depending on where you are and how many users there are, the actual speed of 3G networks will fluctuate. Even though 3G is still more commonly used, the recently introduced 4G networks have quickly become the standard for wireless communication. The 4G networks are 4-10 times faster than 3G protocols and are ideal for ...view middle of the document...

Both of these standards are so similar that many professionals and experts get them confused. One difference between LTE and WiMAX is that they function on different frequencies, making their deployment slightly different. WiMAX is made to work with new deployments, while LTE is made for existing mobile and broadband deployments. Between LTE and WiMAX, LTE is slightly faster and WiMAX is slightly easier to set up. Any wave-based technology, such as LTE and WiMAX, needs to run on a certain frequency to be deployed. This frequency does not affect speed, functionality or dependability, but it does change how the systems are set up and deployed. LTE is made to work on 700 megahertz (MHz), WiMAX is made to work on 2.3 gigahertz (GHz) and 3.5 GHz, and both are able to work on 2.1 GHz and 2.5 GHz.
The WiBro 4G network technology stands for Wireless Broadband. This is offered as an alternative to WiMax. It is a radio service for broadband, mobile access designed in Korea for the purpose of maintaining connectivity on the go. There are similarities between WiBro and WiMax in that the transmission speeds for both are same. However, WiBro has the ability to mark out a receiver that is stirring from one location to another location at speeds of up to 74 miles per hour. WiMax avoids this because it requires a stationary antenna for receiving the signal. The rate of exchange has data rates of 30 – 50 Mbps.

Identify why the competition between the 4G LTE carriers has been so fierce and describe the benefits of this competition to the subscribers.

One factor causing competition between carriers is the customers increase in choices because of the availability of mobile broadband speeds that are directly competing with fixed line access technologies. If an individual can be on the move and have the same level of connection speed as they do at their home or office, their productivity levels increase dramatically. Another big factor are the businesses with remote branch offices that want to adopt a cellular enabled business plan that adopt cellular-enabled business gateways as either primary or back up WAN connections. The ability to offer 4G LTE network technology has taken the competition to a different dimension with benefits for the consumer. The LTE specifications that have been standardized to accommodate rapidly changing user demands and associated network requirements are known as Evolved Multimedia Broadcast Multicast Service (eMBMS). These (eMBMS) services are now a multicast standard for 4G LTE precisely because it allows one-to-many distribution of video content. Prices are decreasing by having more than one carrier offer the (eMBMS) as the foundation of their service plan. Data plans have become more competitive in pricing and the desire to be the order winner is causing carrier to make improvements to their systems daily. The race to increase coverage areas is motivating the competition along and spreading the benefits to...
