List the WiMax protocol which has been implemented in steps 7 and briefly explain each. Initial Ranging Negotiation Authentication Key Distribution Registration Call Activation 2. State 2 differences between WiMax and HSPDA technology wiMAX HSDPA Mobile WiMAX has been framed in such a way that it is able to work in different channel BW's ranging from 1.25 to 20 MHz. The data transmission is up to 8-10 Megabits/sec over a bandwidth of 5MHZ. The security service in a WiMAX is used by an operator to gain benefits from this service as there is always a chance of theft of sIDervice in connections, bandwidth and so on. Hence the security service is divided into two parts namely the encryption and the authentication/key derivation. In HSDPA, users are authorized by their SIM (or RUIM) cards. HSDPA does not provide any additional security functions.
  14. 14. DONE BY : DHARCCANADEVI CONCLUSION Advantages of WiMAXtechnology : WiMax as a new wireless technology has greatly overcome the gaps left by the WiFi. The major drawback with the WiFi technology was that it was not able to cater the needs of far off users.

  16. 16. DONE BY : DHARCCANADEVI 18. WiMax Support to Internet Backbone WiMax is the only wireless technology which can be directly linked to the basic internet backbone with the help of optical fiber cable. This would not only increase the efficiency of the network, but also enables to provide internet access to those users where it is not possible to take traditional internet set up. This is the reason why major telecommunication and mobile companies are trying to merge WiMax with other cellular networks. This combination would not only increase the velocity and capacity of mobile signals but also is cost friendly. The WiMax technology does not hold any additional royalty charges if they are blended well with 3G technologies. Besides being convenient to use people are still reluctant to adopt it as a major wireless technology. 19. The High Signal Strength of WiMax The WiMax technology works in the licensed radio frequency spectrum this gives WiMax a way to generate strong signals. This strong signal can also be contributed to the time slot distribution to the various WiMax vendors. Hence one vendor cannot enter into the spectrum of others. This stops the overlapping of the signals hence they are delivered on time to their respective destinations. The WiMax revolution has also brought some really smart devices with it like the smart antennas. These antennas help in Line of sight service for wireless connection, the fixed antennas are implanted on the roof top for improving signal strength. The WiMax technology is considered as a last mile broadband access due to its ease of installation. 20. General Benefits of WiMax Technology The major benefit of this technology is that it comes with the simplest architecture. One only has to employ a WiMax tower and the connection can be established. This technology is really helpful in establishing sudden and fast network connections in remote areas where a connection can not be established. Many WiMax networks were instantly established to handle the communication needs in the time of disaster and catastrophe. In 2005 when Katrina typhoon struck Florida, WiMax networks were there to serve the communication needs of the people and volunteers. Also WiMax can be greatly used to develop the WLAN network; this is because both the technologies make use of OFDM. In addition to this WiMax is greatly adopted due to its long range coverage of more than 30 miles. It is also cost effective because it can provide the people in remote areas with a T1 connection at affordable prices. This technology can be used along with other mobile technologies to increase their versatility. It is capable enough to t ransfer data, voice, video and VoIP signals. This wireless technology can replace the expense and multifaceted use of wires with single WiMax tower. A single WiMax connectivity can support 60 businesses because it is capable of sharing data rates of up to 70bits/sec. the current speed and bandwidth of WiMax signals can be extended using Line of sight and non line of sight technology. Moreover the specific devices like smart antennas are now used to increase the strength of signals to maximum.
