Business prospect of launching blackberry with video calling in CDMA

  1. 1. Business Prospect of Launching Blackberry with video calling in CDMABy- PRANITA MEHTA
  2. 2. Introduction  Blackberry has provided video calling facility on BBM for the first time on the recently launched Blackberry Z10 and Q10 phones.  Before this, there was no video calling on Blackberry devices.  In this presentation, I will attempt to analyse whether a Blackberry phone with video calling facility in CDMA will be successful in the market.
  3. 3. Two Technologies  There are two types of network technologies for wireless communication today: (i) CDMA (ii) GSM
  4. 4. CDMA Technology  CDMA stands for Code Division Multiple Access technology, which is completely distinct from GSM system.  Code division multiple access (CDMA) is a channel access method used by various radio communication technologies.
  5. 5.  CDMA is used as the access method in many mobile phone standards such as cdmaOne, CDMA2000 (the 3G evolution of cdmaOne), and WCDMA(the 3G standard used by GSM carriers), which are often referred to as simply CDMA.  CDMA is used as the second and third generations of the wireless communication.  It does not use the SIM card, rather gives a specific serial number to the handsets.  CDMA systems use multiple access schemes, which are pioneered by QUALCOMM, etc.
  6. 6.  The conventional communication systems use const ant frequencies, CDMA uses multiple access, or multiplexing. Accomplished through the specific type known as spread spectrum in this case, multiplexing uses varied frequencies to transmit audio signals. This, coupled with code division, which requires a certain code to send and receive the frequency, further protects CDMA communications from interference.  While some countries outside of the United States offer CDMA technology, it is not as widely used outside of the U.S., as is GSM technology.
  7. 7.  Unlike GSM which has a SIM card, so that the phone can be easily swapped, CDMA cell phones have an inbuilt R-UIM(Removable User Identity Module) where this is not possible.
  8. 8. Advantages of CDMA  Call quality is better than GSM system.  Greater coverage for lower cost  Improved security and privacy  Increased Data Throughput  The phone calls are more secured because of the spread spectrum.
  9. 9. Disadvantages of CDMA  Very few number of CDMA handsets are available in the market.  It has only a few service providers, which can be uncomfortable for the customers in case of low service level.  If you want to upgrade the CDMA phone carrier, you will have to deactivate the present one and activate the new. In doing so, the phone with the initial carrier becomes useless.  If you are frequent overseas traveller, the CDMA coverage is sure to make you upset.
  10. 10. GSM Technology  GSM stands for Global System for Mobile Communications.  It came in the market in the mid of 1980’s and generally operates in the 900 and 1800-MHz bands.  SIM cards are small in size, with removable memories and hold a lot of data and numbers of identification which are required to access any wireless service provider. SIM card is bound with the network, instead of the handset. It can be easily interchanged with another GSM phone by just swapping it out.
  11. 11.  GSM works on the basis of Time division multiple access (TDMA). TDMA allots a specific time period on a specific frequency to the GSM.  GSM network connections are considered better secured than CDMA. GSM divides its frequency bands into many channels, so that a large number of users can make a call through a single tower.  GSM covers up to 82% of the global market.  Presently GSM supports more than one billion mobile subscribers in more than 210 countries throughout the world.
  12. 12.  The GSM provides basic to advanced voice and data services including Roaming service. Roaming is the ability to use your GSM phone number in another GSM network.
  13. 13. Advantages of GSM  Improved spectrum efficiency.  International roaming.  Low-cost mobile sets and base stations (BSs)  High-quality speech  Compatibility with other telephone company services.  Support for new services.
  14. 14. Disadvantages of GSM  The per-unit charge on roaming calls is higher in GSM than CDMA.  Calls made through GSM mobiles can be tampered.  If the SIM gets lost, one can lose all the data, if the same is not saved in the phone.
  15. 15. Comparison  The number of GSM users is very large as compared to the number of CDMA users.
  16. 16.  The GSM Association estimates that technologies defined in the GSM standard serve 80% of the global mobile market, encompassing more than 5 billion people across more than 212 countries and territories, making GSM the most ubiquitous of the many standards for cellular networks.
  17. 17.  Global Reach: GSM is in use over 80% of the world’s mobile networks in over 210 countries as compared to CDMA. CDMA is almost exclusively used in United States and some parts of Canada and Japan. As the European Union permissions GSM use, so CDMA is not supported in Europe. In North America, especially in rural areas, more coverage is offered by CDMA as compared to GSM. As GSM is an international standard, so it’s better to use GSM in international roaming. GSM is in use by 76% of users as compared to CDMA which is in use by 24% users.
  18. 18.  Coverage: The most important factor is getting service in the areas you will be using your phone. Upon viewing coverage maps you can discover that GSM network has a wider coverage as compared to CDMA network. It is because the GSM network came into existence before the CDMA network and the number of GSM users are more than that of CDMA users.
  19. 19.  Data Transfer Speed: With the advent of cellular phones doing double and triple duty as streaming video devices, podcast receivers and email devices, speed is important to those who use the phone for more than making calls. CDMA has been traditionally faster than GSM, though both technologies continue to rapidly leapfrog along this path. Both boast "3G" standards, or 3rd generation technologies.
  20. 20.  Subscriber Identity Module (SIM) cards: Only GSM phones use SIM cards. The removable SIM card allows phones to be instantly activated, interchanged, swapped out and upgraded, all without carrier intervention. The SIM itself is tied to the network, rather than the actual phone. Phones that are card-enabled can be used with any GSM carrier.
  21. 21.  Security: More security is provided in CDMA technology as compared with the GSM technology as encryption is inbuilt in the CDMA. A unique code is provided to every user and all the conversation between two users are encoded ensuring a greater level of security for CDMA users. The signal cannot be detected easily in CDMA as compared to the signals of GSM, which are concentrated in the narrow bandwidth. Therefore, the CDMA phone calls are more secure than the GSM calls. In terms of encryption the GSM technology has to be upgraded so as to make it operate more securely.
  22. 22. Business Prospect  In order to find out whether the launch of Blackberry with video calling in CDMA will succeed or not, a comparison needs to be drawn between video calling facilities on CDMA and on GSM.
  23. 23. Video Calling Facility  As of yet, very few Blackberry phones support video calling facility.  Blackberry messenger is one of the most popular applications on the BlackBerry platform, and now it’ll include video calling and screen sharing on the new BlackBerry 10 phones which were launched recently.
  24. 24.  The relevant criterion to be compared is the data transfer speed. It has been seen that both technologies can be used with 3G standard phones, but 3G GSM speeds can be faster than 3G CDMA speeds, which can make a big difference for those who use their phones for social networking, email and streaming video.  They both have derivatives for use with 3G phones known as Universal Mobile Telecommunications System (UMTS) for GSM and CDMA2000 for CDMA, respectively.
  25. 25.  The fastest 3G standard used with CDMA2000 is EV-DO Rev B., which has downstream data rates of about 15.67 Megabits per second (Mbit/s). The fastest standard available with UMTS is HSPA+, with downstream speeds of up to 28 Mbit/s.  Further, UMTS systems use stronger encryption schemes than CDMA2000 systems do, and provide multiple layers of protection for both the subscriber and the network operator.  Notably, UMTS also supports wideband and ultra wideband variants of AMR, providing higher quality voice calls.
  26. 26.  UMTS systems also support true video calling by combining the voice channel with a video channel (packet data channel is not used for this).  At comparable performance and capacity levels, UMTS uses less spectrum than CDMA2000, but initial deployments of UMTS require more spectrum than CDMA2000.  HSPA+ adds to a UMTS network by providing a major upgrade to the data transport system, which can grow to provide the data speed and capacity subscribers need and want.
  27. 27.  On the other hand, CDMA2000 is pretty much dead in terms of innovation. The EVRC voice codecs used in CDMA aren't nearly as good as the GSM AMR codec family (and EVRC isn't a well-designed codec to begin with, either). CDMA2000 has practically no support for native video calling, while UMTS and LTE (through VoLTE) do.  Thus, launching a Blackberry with video calling in CDMA will not be a viable prospect and will not be successful in the market.
