Easily remove watermark of Windows 8 Consumer preview

Microsoft released "Windows 8 Consumer preview".Which is a preview of the Microsoft's next version of Operating system after "windows 7".

Download Windows 8 from here ( If you haven't done-it is totally free )

This version of Windows has targeted mainly on mobile computing and it will be very handy in Laptops,Tabs and Smart-phones in future.

There is a watermark on the desktop after instaling the Windows 8 Consumer Preview.Which can be seen on the right bottom of the Windows 8 desktop.
I am giving you a small software, which removes the watermark very easily.You may not need any advance computer knowledge.Just download the software and run it.

Here is the link to download ,

Run this software. you may see a interface like this.


Tick "remove all watermarks" at the top and click on Apply new settings.Wait few time until this finishes the operation.

Here you go..Enjoy windows 8

Difficulties in Radio Interface and Solutions to Them


a)       Path Loss
Increase Power
Path loss if fading the transmitting or receiving signals with the distance increases. Increasing the transmit power is a solution for this problem. But there are limitations in transmit power.
Idle mode cell changing
To avoid receiving strength failures, MS always measure the receiving signal strength from connected cells and its neighboring cells. If a neighboring cell’s signal strength is higher and MS is in idle mode then MS listen to its BCCH and make connection to that cell’s BTS.
Handover
However when MS is in active mode (In a call) then this procedure is bit of tricky since traffic channels should be changed. Handovers are controlled by the BSC according to the hand over definitions in the site.

b)       Shadowing
Shadowing is path failures due to obstacles in the air interface. This is unavoidable but it can be minimized by proper planning.

c)       Multipath Fading
Multipath fading occurs due to existence of more than one receiving paths of signal.
Rayleigh fading
These signals might be a reflection from a space and it is identical to the original signal and only a phase changes are there. This is also called ghost signals. There are some ghost cancellation technologies to avoid the problem.
Time Dispersion
Time Dispersion is also a multipath fading but due to reflecting from distance bodies there may be time differences in signals.

d)       Time Alignment
A large distance between the MS and the BTS causes time alignment. Effectively, the signal cannot travel over the large distance within the given time. So the part of a particular timeslot’s signal may come in next timeslot’s time. To avoid this problem a special time adjustment is used in air interface. This is called the Timing Advance (TA). It instructs MS to transmit certain time before the actual time it transmits. BSC calculate and transmits the TA to the MS.
e)       Capacity and Frequency Limitations
Allocating same set of frequencies in neighboring cells is not applicable with conventional GSM. But with the growth of the network need of more capacity raised as a big problem. Frequency hopping techniques were introduced to overcome this problem.
