Difference between GSM and CDMA
learn what is difference between gsm and cdma technologies:
The birth of mobiles created gateways for many networking companies to set their foot in the field of mobile technology. Today there are two most appreciated mobile network technology that are ruling the market. All the mobile network service providers nowadays are heavily depending on either GSM or CDMA. Both these technologies are accelerating the demand of mobiles.
Generally, speaking GSM and CDMA are both used for mobile communication process, but still there are some differences between them that allow them to remain intact with their individuality. Companies like T-mobile, Verizon and many other are today using any one of the technology. Talking about GSM, the entire concept came into existence in the year 1987 and since then they are developing and nurturing the entire process of wireless technology. On the other hand the CDMA is a baby of U.S based organization that dominates in the entire Northern region of U.S and Asia, is slowly making its way in the other parts of the world as well.
The architecture of both the network is supported by arguments from their voters, each trying to prove the speciality and efficiency of the network, however, the argument is still on. Explaining the facts and difference between both the networks to the end user will certainly play a different impact. The differences are stated considering the following factors;
Network Coverage: For the user, it is important to check the type of network available in the region where the mobile will be used. This will guide them with the details about the competitors and their services. It might also happen that either of the network is available, which certainly leaves them with no option.
Speed for Data Transition: As nowadays mobiles are much more than just a calling device, their multitasking has surely made them like a little genie, which are competent of handling more than what can be said. To perform these tasks the mobile seeks for a network that can empower its abilities and can make them perform at a higher speed.
Both CDMA and GSM are 3G technologies, but still they have different set of performance factor. The GSM technology is said to accelerate performance by 384 kbps, along with EDGE technology, however, in the real world the speed lies around 275 to 380 kbps.
Power of SIM Cards: Generally the mobile phone comes to life when the SIM card is inserted. GSM phone duly support this technology. Here the SIM is actually already connected with the network, so when one inserts this card in their mobile, automatically after switching on the mobile get on to the same network, on the other hand the neither CDMA phones are not card based phones. Here the sets are proprietary based, therefore in case of switching phone; the carrier needs to deactivate the old phone and then activate the new phone, and this discards the early sets.
National and International Roaming: GSM have a wider coverage as it has contracts with other GSM carriers. This often are very good for the users as the roaming charges in such a case are waved off and user enjoy full service with no extra cost. On the other hand the CDMA user does not enjoy the wider coverage. Mainly the rural areas are left untouched. Apart from that they also have to shell extra money as for enjoying services while they are on move to locations beyond their prime location.
When it comes to international roaming, the GSM cards allow the user to make calls to any part of the world due to their dominance in the market. On the other hand if the user is travelling to international locations then to save money they can use a local SIM and can enjoy calling other places at fairly reasonable rate. However, the CDMA phones are not of much help in case of international roaming, because they are not card based phone. Though there are many countries that have CDMA networks but then the user need to discuss things with their network provider.
These differences do state that the numbers of users of GSM are fairly high in comparison with the CDMA. Once CDMA incorporates some flexibility in their system there are great opportunities for it to attract more users, as things will be more clear and transparent.
