 Mobile YMAX 2.0 is marked by its radio interface design like LTEA because after all in the next generation networks most of the research has gone into defining advanced modulation techniques and antenna design etc. So Mobile YMAX 2.0 wireless interface or the radio interface has some similarities and then certain differences with LTEA. Let's explore these. The ITUT IMA-T requirements as specified in the NGN architecture for Mobile YMAX 2.0 are quite similar to the requirements put up for LTEA and that is why we see that the spectrum allocation here is again quite similar. Like LTEA here the spectrum allocation can start from 1.4 MHz up to 5 MHz in a single chunk within a band then up to five different bands occupying a total of 20 MHz for a single carrier. Now while these similarities make some kind of interoperability viable and possible there are some differences also for instance the downlink for LTEA and Mobile YMAX 2.0 are not much different. Both of these are based on OFDMA or orthogonal frequency division multiple axis. When it comes to uplink in LTEA it is single carrier frequency division multiple axis which is quite advanced and it is highly suited for mobile phones because it does not need high transmission power saves the overall battery drainage on the mobile phone. When it comes to YMAX 2.0 the uplink is actually based again on OFDMA so it means in terms of symmetry we can say YMAX 2.0 is more symmetric because the uplink and the downlink are the same when it comes to LTEA the downlink is OFDMA based but the uplink is SCFDMA. In addition the the way radio resources are organized in LTEA through the Radio Resource Control Module RLC, Radio Link Control Module RLC the design of the resource blocks or the components of Mobile YMAX 2.0 are different so that makes certain other changes like the overall frame structure of YMAX 2.0 is very different from LTEA and when it comes to Radio Resource Management that is when certain frequencies are to be allocated and then in Interference Mitigation Requirements certain steps have to be taken so again both LTEA and Mobile YMAX 2.0 differ in summary we can compare both of these that is 802.16ms Mobile YMAX 2.0 physical layer and the data link layer and LTE advanced we can compare them starting from the data rate the peak data rate in downlink and uplink both for low mobility and high mobility scenarios then we have the spectrum that can be allocated to both of these. The latency for for the control path and for the bearer path it is it is it is more or less the same we are expecting some changes here obviously because these two technologies are essentially different then we have the MIMO techniques you can see that we have downlink is 8 x 8 it actually means simultaneously 8 frequencies can be allocated for transmitting and 8 frequencies for receiving and on the uplink side that is on the mobile side it can be 4 x 4 in LTEA it is again 8 x 8 and 4 x 8 the spectral efficiency is here 15 30 you can just have a look mobility support is interesting both of these can support links at speeds as high as 350 kilometers an hour think about using these technologies while you're traveling in in a bullet train so your connectivity would still be valid normally on like motorways we do not exceed 120 kilometers so we are likely to have a pleasant experience for browsing when we use both these technologies so then we have the access schemes and then we have the cell edge spectral efficiency this specifically relates to the bits per second per hertz which can be achieved at the intersection or the border of adjacent cells
