Introduction The world lives a large evolvement in all life aspects. Everything moves in the comfort direction. One of these aspects is the technician aspect and it is an important part of everyone 's life as every thing around you become technician. In your room there is a TV, mobile, laptop...etc. Even most of kids ' toys became in need to a remote control. The wireless technology means no need to wires or cables. Wi-fi and Bluetooth are examples of that. Mobile wireless industry now is in the

Orthogonal Frequency Division Multiplexing or OFDM is a modulation format that is being used for many of the latest wireless and telecommunications standards. OFDM has been adopted in the Wi-Fi arena where the standards like 802.11a, 802.11n, 802.11ac and more. It has also been chosen for the cellular telecommunications standard LTE / LTE-A, and in addition to this it has been adopted by other standards such as WiMAX and many more. Orthogonal frequency division multiplexing has also been adopted

summarized to complete the term paper . CDMA and GSM are the two types of technologies or way used in cell phones for transmitting the digital signal over the air . CDMA stands for Code Division Multiple Access as from the name it is clear that in this technologies the radio frequency are divided so that multiple user can access the same wireless spectrum . GSM stands for Global System for Mobile Communication as from the name it is clear that History of GSM and CDMA .

WEEK 1 QUIZ The _________ is a term for the device or unit that originates the information transfer. Answer * receiver * transmitter * repeater * amplifier 5 points Question 2 A half-duplex circuit carries information ______________ . Answer * both ways but only one way at a time * only one way * both ways simultaneously * none of the above 5 points Question 3 The _________ is a term for the device or unit that receives the information transfer

communication services at a low speed. The competitive rush to design and implement digital systems led again to a variety of different and incompatible standards such as GSM (global system mobile), TDMA (time division multiple access); PDC (personal digital cellular) and CDMA (code division multiple access).These systems operate nationwide or internationally and are todayʹs mainstream systems, although the data rate for users in these system is very limited. The 2.5G it is basically an enhancement of the

In 2016, the majority of networking is done wirelessly. Advancements in technology over the past ten to fifteen years has allowed us to network wirelessly anywhere in the world. There are remote areas in the world that do not allow wireless networking due to resources being unavailable, at least for now. The world of networking is continuously growing. I would predict that with initiatives such as Facebook’s WiFi Drone, WiFi will be available everywhere in the world no matter your location. The

A portion of the responsibilities that I found on the internet for a mobile device repair technician and what they have to do on a day to day obligation in being a mobile device technician is to be able to do these responsibilities and be able to fulfill them in a full time or part time position as a technician. The First thing to have is too having knowledge of the phone they are working on or somewhat information on the mobile device and to be able to operate the device so that they can try to

CDMA is additionally more secure than GSM by nature of the code division outline. CDMA obliges in any event twice the same number of clients per MHz than GSM. To add to this, CDMA gives a higher-quality transmission even under weaker signal qualities . Advantage of using CDMA : - • Increased cell correspondences
