CDMA performance for rural telecommunication access Abstract: In this paper, we highlight the challenges, benefits and difficulties of extending the telecommunication infrastructure to rural areas.

Technologies that can be implemented in rural areas are highlighted and the system that best suits rural areas is chosen. A cost comparison between GSM and CDMA is carried out, with path loss exponent, fade margin and penetration varied to determine the net return profit.

In the simulation, the path loss exponent is varied between 5. The simulations show that WCDMA is the best option in a rural area, especially with a path loss exponent greater than 4. Article :. DOI: Need Help?

What’s the difference between CDMA and GSM?

On the other hands, the CDMA is handset specific. CDMA is Handset specific. Full Form Global System for Mobile communication. Code Division Multiple Acess. There are a physical channel and a dedicated code for each device in the network. Transmission Voice and data transmission at the same time.

What is the Difference Between GSM and CDMA

The CDMA is based on spread spectrum technology which makes the optimal use of available bandwidth. It allows each user to transmit over the entire frequency spectrum all the time. On the other hand GSM operates on the wedge spectrum called a carrier. This carrier is divided into a number of time slots and each user is assigned a different time slot so that until the ongoing call is finished, no other subscriber can have access to this. TDMA provides multiuser access by chopping up the channel into different time slices and FDMA provides multiuser access by separating the used frequencies.

When consumers think about mobile network providers, their primary concern is with regards to coverage, quality, support, pricing, and other factors but when you pick a network carrier, you also make the choice between a GSM network or a CDMA network, at least in the US. You might have come across these terms in the past when picking a mobile phone, or when first joining, or switching network carriers, but what do they mean? And what is the difference between the two?

What is GSM?

The cellular mobile service is being used everywhere, every day in the world by millions of people. Definitely, We have to agree that- the cellular is one of the fastest-growing and most demanding telecommunication services. Through the evaluations of cellular telecommunications , various systems have been developed and they have many problems directly related to compatibility, especially with the development of digital radio technology. What is GSM? This is a worldwide standard for digital cellular telephony.

Thus, is also known as a SIM type of system. Hence is regarded as a phone-based standard system. Generally, these are also distinguished by the way these two systems transmit the data within the network. Comparatively more secured communication is offered by it. Signal detection Easy Quite difficult Encryption Signal must be additionally encrypted as no built-in encryption exist. It offers automatic encryption to the signal.

It was first deployed in Finland in December

Whereas only mobile phones from a set of whitelisted companies can be used with a CDMA network. Attention reader! Writing code in comment? Please use ide.

The cellular mobile service is being used everywhere in the world today. These two technologies differ the way in which the calls and data transfer takes place over a network and mobile. It is a digital mobile telephony system used for trans-receiving of the data and voice signals and is a second generation standard for mobile networks. The MHz frequency band is used mainly in the United States. A GSM phone is a digital cellular technology used for transmitting mobile voice and data services.

Хейл невинно улыбнулся: - Просто хотел убедиться, что ноги меня еще носят.

 - Мидж снова оказалась права. - Идиот! - в сердцах воскликнула.  - Ты только посмотри. Сквозь строй дважды отверг этот файл.

На брусчатке под ногами мелькали смутные тени, водка еще не выветрилась из головы. Все происходящее напомнило ему нечеткую фотографию. Мысли его то и дело возвращались к Сьюзан: он надеялся, что она уже прослушала его голос на автоответчике. Чуть впереди, у остановки, притормозил городской автобус.

 Не знаете, как его зовут. Клушар на мгновение задумался и покачал головой: - Понятия не имею.  - Он поморщился от боли и откинулся на подушки.

Вокруг нее было черно от нитей, готовых ринуться внутрь. Справа бесконечной чередой мелькали кадры, запечатлевшие последние минуты Танкадо: выражение отчаяния на его лице, вытянутую руку, кольцо, поблескивающее на солнце. Сьюзан смотрела на эти кадры, то выходившие из фокуса, то вновь обретавшие четкость. Она вглядывалась в глаза Танкадо - и видела в них раскаяние.

Эта машина помогла предотвратить десятки преступлений, но связанная с ней информация строго засекречена и никогда не будет раскрыта. Причина такой секретности проста: правительство не может допустить массовой истерии. Никто не знает, как поведет себя общество, узнав, что группы фундаменталистов дважды за прошлый год угрожали ядерным объектам, расположенным на территории США. Ядерное нападение было, однако, не единственной угрозой.

Она в страхе повернулась, думая, что это Хейл.

Когда он был уже почти рядом, Сьюзан поняла, что должна действовать. Хейл находился всего в метре от нее, когда она встала и преградила ему дорогу. Его массивная фигура буквально нависла над ней, запах одеколона ударил в ноздри. - Я сказала .

Она посмотрела на часы, потом на Стратмора. - Все еще не взломан. Через пятнадцать с лишним часов. Стратмор подался вперед и повернул к Сьюзан монитор компьютера.
