Wimax vs. Long Term Evolution

One of the things you need to consider when you decide to buy OnePlus One is that its 4G LTE does not work on every network. You better check out the list of bands that the One supports: 1, 3, 4, 7, 17, 38 and 40, the list of 4G LTE networks in your country to see whether it works or not. Since you cannot try, you had better be careful with it unless you want to regret your decision.

WiMAX can transmit speeds up to 50km at 280mbps, and provides options for use in point to point and multipoint configurations.

5G is the fifth generation wireless broadband technology based on the IEEE 802.11ac standard. 5G is provide high speed then 3G and 4G. 5G operates on 5GHZ signal and set is to offer speed up to 1 GB/s.

4G networks offer 10 or more times the data transmission rate of a 3G network. The data rates available on a 4G network allow the cell phone to access information from the Internet as fast as a land-line connection.

There are four major techniques that allocate capacity for wireless WAN communications. These techniques are Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Code Division Multiple Access (CDMA), and Orthogonal Frequency Division Multiplexing (OFDM). (Goleniewski, L. 2007) Each technique has pros and cons when compared amongst each other. The following is a summary of why each technique has a need, and some of the challenges that come with that technique.

Telstra than discovered 3G and 4G Internet now they both do the same thing, which is for you to connect to the Internet but 4g, was created to make Internet streaming faster.

In order to maintain the competitiveness of the 3GPP cellular system, Long Term Evolution (LTE), is developed. For downlink transmission the technique selected is Orthogonal frequency division multiple access (OFDMA). In this time and frequency resources are reused in adjacent cells, inter cell interference becomes the crucial limiting factor. This problem can be overcome by using interference mitigation techniques. The

TDMA uses timing to allow multiple signals within a specified amount of time. This would be like a large group taking turns talking at different time intervals. CDMA uses codes to allow multiple signals with specific individual codes. This would be like a group of individuals speaking in different languages. FDMA uses different frequencies within the signal. This would be like a group of individual speaking at different tones or levels. Using different code, time, frequency and other access schemes allows a large number of signals to be transmitted, identified and differentiated simultaneously.

Multiplexing (OFDM), Multiple-Input Multiple-Output (MIMO) is to consider for reducing the transmission power in cellular BS.

Various voice oriented wireless communications are also covered up like the gsm or cdma services.

It is also believed that the common issues that occur in the LTE network could be reduced drastically if attention if given to certain engineering practices. The research revealed and discussed some of those factors.

Wi-Fi networks use radio technologies called IEEE 802.11 a, 802.11 b or 802.11 g to provide secure. Reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet and to wire networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, with an 11 Mbps (802.11 b) or 54 IV1bps (802.11 a) data rate.

WiMAX consists of five scenarios supported by the network architecture of WiMAX for Microwave access:

3G is the third generation of wireless technologies. It comes with enhancements over previous wireless technologies, like high-speed transmission, advanced multimedia access and global roaming. 3G is mostly used with mobile phones and handsets as a means to connect the phone to the Internet or other IP networks in order to make voice and video calls, to download and upload data and to surf the net.

According to A. Goldsmith (2005), wireless communications technology is asking as functions of mobile access. Since its inception, it has gone through several stages of development. Its wide range of applications to meet growing demand. (A. Goldsmith, 2005) Multipath fading
