IP Multimedia Services over WiMAX: Opportunities for Service Providers and Corporations
|
Abstract
Overview:
The IP Multimedia Subsystem (IMS) framework represents an integrated traffic
of Data, Voice & Video on the same networking infrastructure whereby the
performance of all the three services are optimized. WiMAX holds great promise
as the potential answer to IP Multimedia for corporations.
This report presents analytics for corporate markets of WiMAX (fixed as well
as mobile) that is invaluable to IT & telecom strategists working with OEMs,
service providers, systems integrators, telecom consultancy firms, telecom
migration consultants, & corporate customers that are planning to implement IP
Multimedia services on wireless systems for premium (heavy duty) applications.
The report begins with a comprehensive analysis of the evolution of IP
multimedia services for corporations on legacy platforms such as the Cisco
AVVID and presents the challenges left for the forthcoming technologies by
IEEE 802.11 based WiFi framework. Furthermore, the report presents how WiMAX
can fulfill the challenges left unaddressed by WiFi for wireless enabled IP
Multimedia services thus offering a huge market to be tapped by WiMAX OEMs,
WiMAX Service Providers and WiMAX Systems Integrators.
An analysis of opportunities offered by the UK Economy alone reveals that
WiMAX equipment market is close to $600 Million and services market close to
$12 Billion in the SMEs & Corporate Sector in UK alone. If the same analytics
is extended to the Global SMEs and Corporate market, a market worth >$10
Billion for equipment and >$100 Billion for services is waiting to be tapped.
The report analyzes strategies of four major players in the WiMAX equipment
industry: Cisco, Intel, Motorola and Alcatel-Lucent.
The report also evaluates why Nokia and Nortel decided to exit the WiMAX
market.
In this report, the following four broad market segments are classified:
- (a) Individual customers retail
- (b) Individual customers corporate
- (c) Corporate engagements for mass users - LAN
- (d) Corporate engagements for mass users - WAN
This must have report also provides proposed solutions to the concerns of
global technology companies regarding technology war between WiMAX and
cellular broadband. This report also represents a critical study of the past
achievements, mistakes, and future outlook into the application of wireless
technologies for corporations. The report will help telecom and IT decision
makers to enhance end-user satisfaction, enhance revenue per customer, and
improve overall ROI.
Select Key Report Findings:
- IP Multimedia Subsystem will not penetrate corporations until legacy data
networking companies such as Cisco and Motorola develop a structured roadmap
and offer complete range of products. For example, Cisco will need to rebuild
AVVID like framework for IMS.
- SIP may not replace H.323 unless IMS roadmap for corporations is clear.
- With the exception of Alcatel-Lucent, no other companies wish to invest in
R&D of both technologies. Moreover, the Telecom service providers have focused
on subscribers using mobile handsets or tablets should continue using 3G and
wait for commercialization of 4G (LTE).
- The Telecom service providers should not position 3G as broadband service
on laptops but should rather focus on 3G broadband services on PDAs/Mobile
Handsets with a roadmap to adopt 4G (LTE). Similarly, the WiMAX broadband
Internet markets (fixed and mobile) should focus on laptops, desktops and
pocket PCs but not on handsets.
- WiMAX has addressed all the gaps left by the WiFi technologies and hence
should be considered for wireless IP Multimedia corporate applications (like
IBM Sametime, Microsoft Communications Server, Go To Meeting (on Citrix),
WebEx, etc. in SMEs and Corporations.
- There is no technology war among 3G, 4G, WiMAX (fixed & mobile) and
802.11e. All the four technologies have different visions and are expected to
settle down in their own respective markets except minor overlaps due to
demographic, political, service provider' s strategic positioning, etc.
- The services for general subscribers and SMEs/Corporations should be
segregated by the service providers by providing (preferably) dedicated
channels to SMEs/corporations not mixed with channels serving general
subscribers. Also, corporate services are for serious business applications
and hence their retention and value per customer would be much higher compared
with general customers who would use most of the IP multimedia services for
fun.
- 3G with IP Multimedia Subsystem services (IMS based) is to be positioned
for general mobile subscribers, 4G with IP Multimedia Subsystem services (IMS
based) is to be positioned for premium corporate mobile subscribers, fixed
WiMAX is to be positioned for rural subscribers for broadband services and
fixed & mobile WiMAX (with segregated channels) is to be positioned for
SME/Corporate subscribers for broadband services with traditional IP
multimedia services (H.323 based). In addition, WiMAX has a large market for
backhaul connectivity and as replacement of OFC last mile in corporate
Internet connections. In many cases, it can be included as a backup to
corporate leased circuits connecting to Internet.
Select Questions Addressed in Report:
- (a) What should be the positioning of IP Multimedia Services for corporations?
- (b) What should the positioning of WiMAX for IP Multimedia Services for corporations? Should 3G enter into this market?
- (c)Can WiMAX deliver against the expectations of corporate IT Managers that were left unfulfilled by WiFi solutions?
- (d)Will the world witness a technology war between WiMAX, 3G and 4G with respect to IP Multimedia services?
- (e)What should the service providers keep in mind when targeting end customers and the corporate decision makers keep in mind when choosing services?
