Cellular Fundamentals
Emerging Applications
and
Regulatory Issues
Bellevue Community College
Bob Young, Instructor
Introduction
The following presentation is divided into two broad categories:
1. Emerging Applications
2. Wireless Regulatory Issues
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.
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.
Craig McCaw Comments at WCA 2004June 2, 2004
"There has not yet been a successful wireless broadband company."
Craig McCaw Comments at WCA 2004June 2, 2004
During his speech, McCaw launched his new wireless broadband venture, Clearwire.
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.
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.
Reminder: my comment about the place of voice in the 3G
network
"Voice becomes a feature - perhaps not the driving
characteristic - of the network"
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
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
Policy Server
Associated with the AAA system Used to authenticate subscribers (or
devices) Permits access to subscribed content Blocks access to unauthorized
content
Hotlining (part 1)
The process of determining when a subscriber needs to be redirected, and
then the act of redirection.
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)
"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)
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
MVNO Characteristics
1) "Owns" the customer relationship
2) Can provide exclusive content to its customers
3) Can provide all customer support
4) Can manage all billing
MVNO Contracts
If the contract is worded right, a virtual network operator can enter into an MVNO agreement with more than one wireless carrier.
The Carrier and the MVNO
On the other hand, wireless carriers can provide MVNO services to more than one virtual network operator.
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
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
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.
MMS Applications (part 1)
• Downloadable/streaming music and video
• Downloadable and interactive gaming
• Consumer information and directories
• Dating services
• News and sports services
MMS Applications (part 2)
• Community based rooms such as chats
• Electronic books
• Information subscription services such as medical and legal
• And many more
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.
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
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
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
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
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

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.
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)
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.
E911
"The wireless E911 program is divided into two parts - Phase I and Phase II."
(from FCC web site, 6/3/2004)
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)
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)
E911
"The deployment of E911 requires the development of new technologies and upgrades."
(from FCC web site, 6/3/2004)
E911
"The FCC established a four-year rollout schedule for Phase II, beginning October 1, 2001 and to be completed by December 31, 2005."
(from FCC web site, 6/3/2004)
E911
Carriers have been able to ask for waivers, which, if granted, require filing a quarterly progress report. These reports can be viewed at the FCC web site.
