  1. 1. Mario Eguiluz Alebicto
  2. 2. 1. Time advantage 2. Latency 3. 3GPP Evolution: GSM, HSPA...now LTE 4. Handover and Roaming 5. WiMax, by default with Intel 6. Use of a SIM card 7. A lot of big carriers seem to prefer LTE 8. Developing countries 9. Power consumption 10. Different carrier, different situations INDEX
  3. 3. Analysis of LTE & WiMax <ul><li>WiMax is in the market while Long Term Evolution is still in the labs...So, in this point, WiMax has a clear time advantage over LTE: WiMax is present nowadays in numerous countries around the world. </li></ul><ul><li>There are already a lot of deployments, and WiMax is growing step by step in different markets, not only in urban zones, also in rural and/or emerging markets . On the other hand, LTE is still in the labs, and forecasts say that until 2011-2012 (end of 2010 maybe) it is not going to be in the real market. </li></ul>1. Time advantage When LTE has arrived to the telecom market, WiMax will have already a solid market using it's hardware. However, other technologies, like HSPA+, could decrease that advantage. HSPA+ could compete with WiMax meanwhile LTE arrives... Availability of WiMax, HSPA and LTE
  4. 4. Analysis of LTE & WiMax <ul><li>As it can be seen in the figure above, HSPA R7 can compete with WiMax R3 TDD in terms of BPS/Hz either in the download link or upload link. </li></ul>1. Time advantage Spectrum efficiency of HSPA, WiMax and LTE
  5. 5. Analysis of LTE & WiMax <ul><li>There is a good difference in the latency of WiMax and LTE, and some &quot; real time &quot; multimedia services will get benefit of this. Latency is a key point in some online services, and if one wants to deliver these services in a good way, he will need to pay attention to the Latency parameter </li></ul>2. Latency Latency: LTE 10ms WiMax 50ms
  6. 6. Analysis of LTE & WiMax <ul><li>In some cases the signal must arrive at its destination as soon as possible, in order to maintain a &quot;real time&quot; sensation during the data exchange over the net: </li></ul><ul><ul><li>Online gaming and videoconference . Online gamers always complain about the &quot;ping&quot;. In competitive gaming there is a huge difference between players whether one of them has 40ms less than others. </li></ul></ul><ul><ul><li>The videoconferences will have better performance, without delays in the conversation. There is a solution to a high latency: the use of buffers, that’s true. But there is a point here for LTE, because it do not need special improvements. Also, WiMax uses a bigger overhead in the packets, and that is worse for services like VoIP </li></ul></ul>2. Latency
  7. 7. Analysis of LTE & WiMax <ul><li>Today, there is an important infrastructure around the entire world that allows users to enjoy mobile coverage. This coverage is possible thank to the deployment of different generations of mobile technologies: 1G, 2G and 3G. This infrastructure follows the 3GGP standards , in terms of nodes and protocols. The money invested in all of these nodes is huge, and operators must maximize the use of these facilities. </li></ul><ul><li>Now, 3GGP has researched the next step of the net evolution: LTE . By this reason, LTE seems to be the natural path to GSM and HSPA+. The compatibility between LTE and the other 3GGP's predecessors will result in a easy re-farming potential and in a easy upgrade possibilities . </li></ul><ul><li>LTE is fully integrated with 3GGP, so it is fully integrated with previous infrastructure and protocols. </li></ul>3. 3GPP Evolution: GSM, HSPA...now LTE
  8. 8. Analysis of LTE & WiMax <ul><li>Furthermore, LTE provides FULL mobility . While WiMax needs a mobile target with a speed lower than 120 km/h, LTE still operates with a target up to 350 km/h. </li></ul><ul><li>Summarizing this point, the easy re-farming possibilities, the easy upgrade potential and the full mobility , convert LTE in a “natural” evolution from 3G to 3,9G – 4G. </li></ul>3. 3GPP Evolution: GSM, HSPA...now LTE 3GPP Standard Evolution
  9. 9. Analysis of LTE & WiMax <ul><li>LTE supports handover and roaming with the 3GGP mobile networks. However, these services are not easy to achieve with WiMax. </li></ul><ul><li>This fact is an important point because the roaming service generates numerous benefits for operators: it extends their coverage of the operator using the network of other carriers, it generates more benefits of visitors from other carriers and it provides to users an important service: One can travel far away from the coverage of his operator and the mobile phone is still functional. </li></ul>4. Handover and Roaming Roaming advantages
  10. 10. Analysis of LTE & WiMax <ul><li>It seems that Intel will integrate WIMAX in their new devices...It ensures a good number of WiMax devices in the market by default, which is very good to expand the potential market of WiMax . </li></ul>5. WiMax, by default with Intel
  11. 11. Analysis of LTE & WiMax <ul><li>LTE, like GSM, needs a  SIM card to operate. The use of a SIM card has its advantages and also its disadvantages. </li></ul><ul><li>On the one hand, with LTE, the use of a SIM card is mandatory for the users and that is a requirement for them, which is not good because the users want things easy, so the fewer requirements needed the better . </li></ul><ul><li>On the other hand, the use of SIM card makes easier to provide some services like  roaming , which is a key service nowadays. Identifying subscribers with a SIM makes things easier to the carrier. </li></ul>6. Use of a SIM card
  12. 12. Analysis of LTE & WiMax <ul><li>According to nokiasiemensnetworks.com, there are plenty of telecom carriers around the world that are going for LTE instead of WiMax. Most of them have a GSM structure already deployed, so it is a logic step in their evolution to the next 4G (or 3,9G). Some examples of this are: </li></ul><ul><ul><li>Biggest carriers in the USA: AT&T, Verizon . </li></ul></ul><ul><ul><li>  </li></ul></ul><ul><ul><li>Vodafone . </li></ul></ul><ul><ul><li>  </li></ul></ul><ul><ul><li>China Mobile . </li></ul></ul><ul><ul><li>  </li></ul></ul><ul><ul><li>DoCoMo (2010-2011). </li></ul></ul><ul><ul><li>  </li></ul></ul><ul><ul><li>Others : KDDI, Telstra, Telecom Italia, China Telecom, Orange, and T-Mobile. </li></ul></ul>7. A lot of big carriers seem to prefer LTE
  13. 13. Analysis of LTE & WiMax <ul><li>If biggest carriers go for LTE, It will produce a lower price of LTE products in terms of fabrication: higher volume of production, lower prices. It could be an important point for LTE. </li></ul>7. A lot of big carriers seem to prefer LTE Different carriers with LTE worldwide
  14. 14. Analysis of LTE & WiMax <ul><li>When developing nations face the problem of deploying a new telecom infrastructure in the country, they usually have 2 important preconditions: </li></ul><ul><ul><li>They don’t have any GSM inheritance. </li></ul></ul><ul><ul><li>They need an available technology. </li></ul></ul><ul><li>So with these terms, a lot of developing countries (East Asia and Africa have examples of this) are already deploying WiMax. </li></ul><ul><li>The initial costs of WiMax are lower when the operators do not have any 2G – 3G equipment, so WiMax could be a good option because the CAPEX of WiMax are lower than the CAPEX of LTE, and the initial investment is a key point in developing countries. </li></ul>8. Developing countries
  15. 15. Analysis of LTE & WiMax <ul><li>LTE needs lower power consumption than WiMax. One of the reasons of this is the use of SC-FDMA modulation in uplink channels. </li></ul><ul><li>A low power consumption results in a longer battery life in mobile devices. So LTE has an advantage here, when talking about mobility, the battery life is a main feature of any mobile device like a mobile phone. </li></ul><ul><li>Talking about bigger devices, like laptops, the battery is not an important issue because batteries of these devices last longer. </li></ul>9. Power consumption
  16. 16. Analysis of LTE & WiMax <ul><li>All points detailed above are important, but the conditions or the characteristics of the carrier/operator will override sometimes those points. Lets see some different scenarios: </li></ul><ul><ul><li>Incumbent 3G operators: Upgrading to HSPA, then LTE. </li></ul></ul><ul><ul><li>  </li></ul></ul><ul><ul><li>New 3G operators: If they want to be a full operator (not only access): Invest in HSPA/UMTS network, then LTE. If they only want to focus on the access: WiMax BWA license. </li></ul></ul><ul><ul><li>  </li></ul></ul><ul><ul><li>New operators without licenses: WiMax in urban areas and WLAN in certain hotspots, for example. </li></ul></ul>10. Different carrier, different situations
