1 Succeeding with Technology Overview of Digital Communications

2 Succeeding with Technology Digital Communications Digital communications include all forms of modern electronic communications. Personal communications involve communications that take place outside of industry – this is our focus. Demo: http://secondlife.com/http://secondlife.com/

3 Succeeding with Technology Personal Communications Old Skool Face-to-face  In person Voice  Home phone  Business phone  Public booths Text  Snail mail New Skool - Digital Face-to-face  Video Phone/Email/Chat Voice  Cell Phone  Voice Mail  Internet Phone/Chat Text  Email  Instant Messaging (IM)  SMS Texting

4 Succeeding with Technology Types of Communication Synchronous Communication takes place in real time.  Phone conversation  Instant Messaging Asynchronous Communication allows participants to leave messages to be accessed whenever.  Voice mail  Email  SMS Texting

5 Succeeding with Technology 1.Face-to-face 2.Video conferencing 3.Phone (voice) 4.Instant messaging/Chat 5.Voice mail 6.Email 7.SMS Texting Synchronous Asynchronous Effectiveness Convenience Effectiveness vs. Convenience

6 Succeeding with Technology Emerging Communications Technologies

7 Succeeding with Technology Voice over IP (VoIP) Technology that enables network managers to route phone calls over the same network they use for data.

8 Succeeding with Technology Residential VoIP Residential VoIP, Broadband Phone Phone service over a broadband Internet connection. http://www.voipchoices.com/vonage.html

9 Succeeding with Technology Video Conferencing Video conferencing is a technology that combines video and voice communications along with document sharing.

10 Succeeding with Technology Cell Phone Technology

11 Succeeding with Technology Cellular Network 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.

12 Succeeding with Technology Generations 1 st Gen – analog wireless signal 2 nd Gen – digital wireless signal 3 rd Gen (3G) – broadband digital network that supports both voice and data services such as video  Current 3G services are barely broadband  3.5G with 3 Mbps data rates is under way

13 Succeeding with Technology Generations 4 th Gen  The Wireless World Research Forum (WWRF) defines 4G as a network that operates on Internet technology, combines it with other applications and technologies such as Wi-Fi and WiMAX, and runs at speeds ranging from 100 Mbps (in cell-phone networks) to 1 Gbps (in local Wi-Fi networks). 4G 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.

14 Succeeding with Technology Carriers 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.orgwww.consumerreports.org

15 Succeeding with Technology GSM and CDMA Digital networking standards for cell phone networks are GSM and CDMA. GSMCDMA Cingular AT&T T-Mobile Verizon Sprint Nextel GSM: Global System for Mobile Communications CDMA: Code division multiple access

16 Succeeding with Technology GSM and CDMA GSM Covered in virtually all parts of the world Mature, more stable network with robust features Less signal deterioration inside buildings Talktime is generally higher Subscriber Identity Modules (SIM) allows users to switch networks and handsets at will interferes with some electronics, especially certain audio amplifiers CDMA (IS-95) It can accommodate more users uses soft handoff, reducing the likelihood of dropped calls has a well-defined path to higher data rates are generally unable to roam internationally Smaller market so features are sometimes late in coming to CDMA devices every time you subscribe with a new provider you must buy a new phone GSMCDMA Cingular AT&T T-Mobile Verizon Sprint Nextel http://en.wikipedia.org/wiki/Comparison_of_mobile_phone_standards

17 Succeeding with Technology GSM and CDMA GSM Phones include a subscriber identity module (SIM) for security and convenient data transfer between phones. GSMCDMA Cingular AT&T T-Mobile Verizon Sprint Nextel

18 Succeeding with Technology Choosing a Cell Phone Service Consumers choose a carrier based on coverage area, handsets available, and services provided. 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

19 Succeeding with Technology Choosing a Cell Phone Service 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

20 Succeeding with Technology Choosing a Cell Phone Service Fees:  Using “additional minutes” beyond your service plan agreement can cost big $ in fees  Roaming can cost big $ in fees

22 Succeeding with Technology Cell Phone Features http://www.phonescoop.com/phones/fin der.php http://www.phonescoop.com/phones/fin der.php  Phone Finder  In Depth

23 Succeeding with Technology Cell Phone Technologies Cell phone accessories provide added features for example…  A 2 GB mini SD memory card can provide ample storage digital photos, music, and video files.  A Bluetooth headset allows you to interact with your phone without taking it out of your pocket.  Car chargers allow you to charge your cell phone from your car power supply.  Assorted cases protect cell phones from damage and make them handy to access.
