Cellular Network n A cellular network is a radio network in which a geographic area is divided into cells, with a transmission tower and station at the center of each cell, to support mobile communications. Succeeding with Technology
Generations n 1 st Gen – analog wireless signal n 2 nd Gen – digital wireless signal n 3 rd Gen (3 G) – broadband digital network that supports both voice and data services such as video ¡Current 3 G services are barely broadband ¡ 3. 5 G with 3 Mbps data rates is under way Succeeding with Technology
Generations n 4 th Gen ¡ The Wireless World Research Forum (WWRF) defines 4 G as a network that operates on Internet technology, combines it with other applications and technologies such as Wi-Fi and Wi. MAX, and runs at speeds ranging from 100 Mbps (in cell-phone networks) to 1 Gbps (in local Wi-Fi networks). 4 G is not just one defined technology or standard, but rather a collection of technologies and protocols to enable the highest throughput, lowest cost wireless network possible. [wikipedia] ¡ Anywhere, anytime computing. Succeeding with Technology
Carriers n A cellular carrier is a company that builds and maintains a cellular network and provides cell phone service to the public. See how they rate: www. consumerreports. org Succeeding with Technology
GSM and CDMA GSM CDMA Cingular AT&T T-Mobile Verizon Sprint Nextel n Digital networking standards for cell phone networks are GSM and CDMA. Succeeding with Technology GSM: Global System for Mobile Communications CDMA: Code division multiple access
GSM and CDMA GSM CDMA Cingular AT&T T-Mobile Verizon Sprint Nextel GSM CDMA (IS-95) n Covered in virtually all parts of the world n Mature, more stable network with robust features n Less signal deterioration inside buildings n Talktime is generally higher n Subscriber Identity Modules (SIM) allows users to switch networks and handsets at will n interferes with some electronics, especially certain audio amplifiers n It can accommodate more users n uses soft handoff, reducing the likelihood of dropped calls n has a well-defined path to higher data rates n are generally unable to roam internationally n Smaller market so features are sometimes late in coming to CDMA devices n every time you subscribe with a new provider you must buy a new phone http: //en. wikipedia. org/wiki/Comparison_of_mobile_phone_standards Succeeding with Technology
GSM and CDMA GSM CDMA Cingular AT&T T-Mobile Verizon Sprint Nextel n GSM Phones include a subscriber identity module (SIM) for security and convenient data transfer between phones. Succeeding with Technology
Choosing a Cell Phone Service n Consumers choose a carrier based on coverage area, handsets available, and services provided. n There are typically two service options: ¡ A pay-as-you-go plan is a prepay system in which you buy minutes up front that must be used in a given time frame ¡ Service contracts are typically for two years and involve finding a plan that best matches your usage Succeeding with Technology
Choosing a Cell Phone Service n Calling plan option variables: ¡ Whenever, or anytime, minutes with no time restrictions ¡ Weeknight minutes, typically Monday through Friday, 9: 00 p. m. to 5: 59 a. m. or 6: 59 a. m. ¡ Weekend minutes, typically Saturday 12: 00 a. m. to Sunday 11: 59 p. m. ¡ Rollover minutes are leftover unused minutes passed on from one month to the next ¡ Mobile-to-mobile, or in-network calls refers to phoning other users of the same carrier. ¡ Roaming refers to making calls outside the carriers coverage area using another carriers network Succeeding with Technology
Choosing a Cell Phone Service n Fees: ¡ Using “additional minutes” beyond your service plan agreement can cost big $ in fees ¡ Roaming can cost big $ in fees Succeeding with Technology
