  1. Cellular Fundamentals Emerging Applications and Regulatory Issues Bellevue Community College Bob Young, Instructor

  2. Introduction The following presentation is divided into two broad categories: 1. Emerging Applications 2. Wireless Regulatory Issues

  3. Emerging Applications In this section, we'll take a broad look at several items on the near horizon. The purpose is to obtain a general overview of terms and concepts. Some of them are business oriented, and some of them are technology oriented.

  4. Wireless Regulatory Issues Next, we'll take a quick look at some of the current regulatory issues that will have an impact on the shape of the wireless industry in the years ahead.

  5. Emerging Applications: Wireless Broadband

  6. Craig McCaw Comments at WCA 2004June 2, 2004 "There has not yet been a successful wireless broadband company."

  7. Craig McCaw Comments at WCA 2004June 2, 2004 During his speech, McCaw launched his new wireless broadband venture, Clearwire.

  8. Craig McCaw Comments at WCA 2004June 2, 2004 The new company will offer wireless broadband data as a last-mile alternative to cable and DSL, as well as 2.5G and 3G cellular services.

  9. Craig McCaw Comments at WCA 2004June 2, 2004 McCaw added that voice will likely be a part of Clearwire's offerings, but added that it will not be marketed as an alternative to existing voice services.

  10. Reminder: my comment about the place of voice in the 3G network "Voice becomes a feature - perhaps not the driving characteristic - of the network"

  11. GSM/EDGE/WiFi wireless chip "Wireless chip startup Quorum Systems yesterday unveiled a new mobile phone chip that will enable GSM phones to use both GSM/GPRS networks and Voice-over-WiFi (VoWiFi) systems. The new product, dubbed QC2530, is a single chip solution that allows for seamless roaming between cellular and WiFi networks. It covers 802.11b/g WiFi networks and GSM/GPRS/EDGE cellular networks." --Fierce Wireless, June 2004

  12. Content Service Provider A new "middleman" Intermediary between content providers and carriers Some content providers are not "geared up" to provide their content in a format that can be used by the carrier

  13. Content Service Provider

  14. AAA Server Administration, Authorization, and Authentication (i.e., Software Security)

  15. Policy Server Associated with the AAA system Used to authenticate subscribers (or devices) Permits access to subscribed content Blocks access to unauthorized content

  16. Hotlining (part 1) The process of determining when a subscriber needs to be redirected, and then the act of redirection.

  17. Hotlining (part 2) The subscriber may be redirected for: Validation Payment

  18. Content Providers:Types of Content Location-based services Phone-based dating services Ring tones, ringback tones Interact with TV games Mobile gaming Wireless music videos Video on demand (incl. full length movies)

  19. "In fact, virtually any service that's available over the Internet today is headed to cell phones in the near future -- along with many new innovative services that will catch us all off guard."(Fierce Wireless, May 26, 2004)

  20. Ringtone (not so) Trivia "Downloadable ringtones last year generated $3.5 billion in revenue, equal to about 10 percent of the revenue for the entire music industry." Fierce Wireless, May 26, 2004

  21. MVNO Mobile Virtual Network Operator

  22. MVNO Characteristics "Owns" the customer relationship Can provide exclusive content to its customers Can provide all customer support Can manage all billing

  23. MVNO Contracts If the contract is worded right, a virtual network operator can enter into an MVNO agreement with more than one wireless carrier.

  24. The Carrier and the MVNO On the other hand, wireless carriers can provide MVNO services to more than one virtual network operator.

  25. MVNO Is Unlike A Reseller The reseller: Doesn't "own" the customer Doesn't do billing Doesn't handle customer care Doesn't "brand" the service

  26. MVNO Developments Qwest is becoming an MVNO, with Sprint PCS as the prime carrier After Cingular buys AT&T Wireless, AT&T Corp. will become an MVNO - again, Sprint PCS has been chosen Sprint already provides MVNO service to Virgin Mobile Cingular is providing MVNO services to 7-Eleven

  27. MMSMultimedia Messaging Service MMS is the ability to send messages comprising a combination of text, sounds, images and video to MMS capable handsets, and is a prime method of delivery for many content services.

  28. MMS Applications (part 1) • Downloadable/streaming music and video • Downloadable and interactive gaming • Consumer information and directories • Dating services • News and sports services

  29. MMS Applications (part 2) • Community based rooms such as chats • Electronic books • Information subscription services such as medical and legal • And many more

  30. MMS Key Issue Today: Interoperability 3G Americas and the CDMA Development Group have already announced plans for inter-carrier MMS that will support both GSM and CDMA.

  31. Technical Issue: Data Compression A DVD uses about 6Mbps Currently, we can get that down to about 1Mbps with compression techniques More work needs to be done

  32. Other Technical Issues: Battery life Color displays

  33. 4G "The 4G standard, which pumps data up to the speed of 100 Mbps or around 50 times faster than the current solution, is expected to be commercially introduced in several years." Source: ITU web site, 6/3/2004

  34. 4G "South Korea, Japan and China have agreed to jointly develop technology for fourth-generation (4G) cell phones, which will come into commercial use by around 2010. They also agreed to pull together in garnering frequency spectrum for the 4G technology from the International Telecommunication Union in 2007." Source: ITU web site, 6/3/2004

  35. 4G "India aims to leapfrog to 4G (fourth-generation) wireless technology, skipping 3G technology as it has not been found to be cost-effective, according to Dayanidhi Maran, the country's new minister for IT and communications." Source: ITU web site, 6/3/2004

  36. 4G "India's mobile telephony service providers are currently providing services based on GSM (Global System for Mobile Communications), GPRS (General Packet Radio Service), or CDMA (Code Division Multiple Access) technologies." Source: ITU web site, 6/3/2004

  37. Wireless Regulatory Issues

  38. DRM: Digital Rights Management Users download content with a digital wrapper that determines how they can use, reuse, store or redistribute the content.

  39. CALEA Communications Assistance for Law Enforcement Act

  40. CALEA Three Agencies Involved: Federal Bureau of Investigation Department of Justice Drug Enforcement Administration

  41. CALEA "CALEA’s purpose is to preserve Law Enforcement’s ability to conduct lawful electronic surveillance despite changing telecommunications technologies."

  42. CALEA The FCC extended, until January 30, 2004, the current November 19, 2003, preliminary extension granted to wireline and wireless carriers who filed for extensions of packet-mode surveillance capability requirements.

  43. E911 "The wireless Enhanced 911 (E911) rules seek to improve the effectiveness and reliability of wireless 911 service by providing 911 dispatchers with additional information on wireless 911 calls." (from FCC web site, 6/3/2004)

  44. E911 PSAP Public Safety Answering Point

  45. E911 The FCC mandated that Wireless Carriers be capable of delivering Automatic Number Identification and subscriber location information to PSAP’s by April 1998. This Phase 1 was required when a Bon Fide request was received from a PSAP.

  46. E911 The subscriber location information is the hard part . . .

  47. E911 "The wireless E911 program is divided into two parts - Phase I and Phase II." (from FCC web site, 6/3/2004)

  48. E911 "Phase I requires carriers, upon appropriate request by a local Public Safety Answering Point (PSAP), to report the telephone number of a wireless 911 caller and the location of the antenna that received the call." (from FCC web site, 6/3/2004)

  49. E911 "Phase II requires wireless carriers to provide far more precise location information, within 50 to 100 meters in most cases." (from FCC web site, 6/3/2004)

  50. E911 "The deployment of E911 requires the development of new technologies and upgrades." (from FCC web site, 6/3/2004)
