Ecosystem to Ensure a True Mobile Broadband Experience
New Partners Added to Ecosystem to
Deliver End-to-End WiMAX Solutions
WIRE)--Jun 20, 2007 -- Nortel(1) (Toronto:NT.TO
News) has selected ZyXEL Communications, one of the
world's leading device manufacturers, to join the growing
ecosystem of companies working with Nortel to deliver
broadband wireless communications solutions around the world
based on WiMAX technology. Nortel is also working with leading
WiMAX chipset manufacturers to include chipsets, which will
enable WiMAX capabilities in a variety of devices, in Nortel's
end-to-end WiMAX solutions.
What WiMAX Means for the Enterprise, Mark
A strong WiMAX ecosystem is
important to meeting the mobility demands in the era of
Hyperconnectivity where everything that can be connected
to the network, will be connected, encompassing
person-to-person communication, person-to-machine and
Nortel's WiMAX ecosystem will
allow service providers to take advantage of the opportunities
of a hyperconnected world with end-to-end solutions delivering
the high-bandwidth capacity and super-fast transmission speeds
essential to real-time mobile applications such as VoIP and
video. The true mobile broadband experience that can be
offered over WiMAX delivers the potential to participate in a
video-conference from a mobile phone while waiting for a
flight, or to let the kids pass the time on long road trips by
playing on-line video games from the backseat of the car.
"The development of a
complete WiMAX ecosystem, including infrastructure, chipsets
and devices, is integral to the real world success of WiMAX
technology," said Peter MacKinnon, general manager, Nortel
WiMAX and Wireless Mesh and chairman, LG-Nortel JV. "Nortel is
driving the development of its WiMAX ecosystem by supporting
and pursuing relationships with leading device and chipset
manufacturers like ZyXEL, Runcom and Sequans, to name a few."
Nortel will work with ZyXEL,
Runcom, Sequans and others to offer service providers a
variety of end to end WiMAX solutions. These solution
offerings will include ZyXEL PCMCIA cards and customer
premises equipment (CPE), such as indoor and outdoor
residential gateways, which will be bundled for sale with
Nortel's WiMAX infrastructure technology.
Building on the collaboration
between Nortel and Runcom that was announced on October 10,
2006, the two companies have entered into the commercial phase
of an agreement to include Runcom's MIMO-based RNA200 chipset
- which enables mobile WiMAX capabilities within devices such
as phones and laptops - as part of Nortel's end-to-end WiMAX
Furthering the breadth of the
WiMAX ecosystem, Nortel has successfully conducted initial
interoperability testing of MIMO-based WiMAX products with
Sequans. This testing was conducted at Nortel's R&D labs in
Ottawa and included testing over live air of MIMO Matrix B
which is the technology that makes WiMAX and 4G three times
more spectrally efficient than HSPA.
testing of Nortel's MIMO-enabled WiMAX solutions occurred at
the WiMAX Forum's third annual Mobile WiMAX PlugFest in Sophia
Antipolis, France. This event brought together 33 Mobile WiMAX
equipment developers to test and showcase the interoperability
of their products. This was the first time the WiMAX Forum has
tested key mobility features such as MIMO. Nortel will
continue to build on these successes at its Center of
Excellence - WiMAX 4G Ecosystem in Taipei where vendors and
manufacturers work together to drive the development of WiMAX.
"Our total solution will
include devices essential to easy uptake of WiMAX services,"
said Stone Tseng, director, WiMAX 4G Ecosystem, Nortel.
"Simple CPE connectivity devices like PCMCIA cards, USB
dongles, indoor and outdoor CPE with Ethernet and VoIP options
will be available in the coming months, but that's just the
beginning. Nortel will continue to work with various ecosystem
partners to bring handsets, smart phones, PDAs and other
advanced WiMAX devices to market over the next 12 to 24

A few weeks
ago, Forbes published a list of the top 10 technologies destined to
change the way we live. Fuel cells, gene therapy, and haptics, a
technology that enables users to interact with virtual objects, were
just a few of the innovations making the list, so was VoIP. Rounding
out the top 10 Worldwide Interoperability for Microwave Access, more
commonly referred to as WiMAX an emerging wireless standard that has
seen a meteoric rise in global interest, across every geographic
region and among all industry players in only a few short years.
In spite of its
high profile, a considerable amount of confusion persists. Questions
abound as to how WiMAX will fit in the world of wireless
communications. Will it replace WiFi? Will it compete with 3G
cellular systems? What kinds of providers will offer it? This last
question brings some interesting scenarios to mind looking ahead at
the type of competitive landscape WiMAX could help create. That is
certainly worth exploring, but lets stay focused here on the end
user, considering primarily the implications of WiMAX for enterprise
users and what IT managers need to do to prepare for this
Blackberry and other PDA devices take a subset of enterprise
applications like calendars, contact lists, e-mail, etc. and deliver
them beyond the enterprises walls. Cellular phones long ago breached
this barrier and now enable virtually all voice services through a
network of public operators, and have thus blurred the line between
office and personal communication services. WiMAX will take desktop
computing and morph it into the mobile laptop and other devices yet
to be introduced enabling the Internet to be virtually anywhere and
the laptop to be truly mobile as the cell phone is today.
As mobile professionals and consumers begin to see their computers
as personal, mobile, ever-present devices akin to cell phones, they
will change their behavior and demands, similar to what happened
with the cellular evolution. Laptops will become dual-duty
office/personal devices, blending public and private data
communication services. IT managers will need to prepare for this
virtualization of the boundary around their networks a boundary that
will soon be found inside their employees personal computing
devices. Security, services, partnerships with infrastructure
vendors and network operators, all will be impacted.
How WiMAX Works
WiMAX is designed to deliver broadband multimedia data ubiquitously
over wireless links at several times the speed of traditional
circuit-switched wireless systems, and over a far greater coverage
area than todays proprietary wireless local network (WLAN) access
solutions, such as 802.11 (WiFi) technology.
Where WiFi enables affordable broadband Internet access within
short-range hot spots, at distances measured in tens of meters,
WiMAX is designed to deliver the same access at similar costs, but
across tens of kilometers and ultimately, with greater performance
and higher speeds. In short, where WiFi provides high bandwidth but
not distance, and current cellular systems provide distance, but not
high bandwidth, WiMAX will provide both.
WiMAX will give users uninterrupted and untethered access to a rich
variety of high-bandwidth services not only around offices, homes,
coffee shops, airports, and hotels, but also as users roam in rural,
suburban, and metropolitan areas.
Whats more, with WiMAX, users will no longer perceive wireless
Internet access as being inferior in quality compared with todays
fixed DSL and cable access offers. Instead, WiMAX is expected to
bring long-sought-after performance parity between wireless and
wired Internet access.
These capabilities are possible because the standard upon which
WiMAX technology is based IEEE 802.16 is being designed from the
ground up to be truly broadband and packet based. A
non-line-of-sight technology, IEEE 802.16e (the e refers to the
mobile version of the standard) is based on orthogonal frequency
division multiplexing (OFDM) and OFDM with multiple access (OFDMA),
a new air interface that brings significantly improved levels of
spectral efficiency, data throughput, and capacity compared to
previous generations of radio technologies. Moreover, when combined
with multiple-input multiple-output (MIMO) antenna processing
technology, the resulting OFDM-MIMO combination can boost capacity
and performance even further.
Will WiMAX Replace WiFi?
WiMAX and WiFi are somewhat independent, addressing slightly
different needs. WiMAX uses private, licensed spectrum and provides
WiFi-like service with guaranteed performance to larger public
areas, similar in coverage to cellular networks today. WiFi uses
shared spectrum and operates at short distances, making it ideal for
low-cost, private networks (where usage of the network is
constrained to an office building or campus) or free public systems
(where service guarantees are not required).
Companies like Intel are committed to delivering dual-mode chipsets
(WiFi + WiMAX) for next-generation devices. This would allow a user
to access WiFi in the office, school, or home, and then roam onto a
public WiMAX network after leaving the WiFi coverage area. WiMAX can
also deliver the last-mile connection to a home or office where
cable or DSL service doesnt reach.
Will WiMAX Have Any Performance Problems?
Early WLANs struggled with security and latency issues. WiMAX is
being implemented based on WLAN lessons learned and will be
equivalent to WLAN state-of-the-art security. And, WiMAX wont suffer
from the same performance problems in cases where it is deployed in
licensed spectrum (which is where the majority of it will be
deployed), or in low-density rural areas using unlicensed spectrum.
This is because a single network owner engineers and controls the
usage and configuration of the network, avoiding the tragedy of
commons scenario in public WiFi networks. At the same time, WiMAX
will share WiFis most attractive attributes: ease of use, high-speed
connections, and a wide variety of low-cost devices available
through conventional outlets.
Will WiMAX Compete With Cellular Or 3G?
A lot of debate has centered around whether these two technologies
will compete with or actually complement one another. The truth is,
the answer is more nuanced than a simple yes or no. 3G is coming up
from the voice world trying to do as much data/Internet functions as
it can, but its stretched pretty far. Theres going to be a limit as
to how much more broadband it can get. Also, the more broadband
youre pulling, the bigger the screen has to be because theres a
relationship between a devices size and how much bandwidth it
requires. WiMAX makes more sense for laptops than handsets. On the
other hand, WiMAX isnt designed for mobile voice. It will offer a
better version of data than 3G, but it becomes challenging to offer
voice with WiMAX when roaming.
Is WiMAX Currently Available?
The fixed 802.12-2004 standard is now available and well-suited for
the last-mile-type access mentioned above where cable or DSL service
cant be economically provisioned to a home or office. In North
America alone, there is a significant rural market of under-served
communities that fixed WiMAX can address.
The first of these 802.12-2004 networks will launch later this
summer in Alberta, Canada. Once up and running, it will operate in
the 3.5GHz spectrum band and be available to roughly 80 percent of
SAB residents and businesses, equipping them with fixed broadband
wireless access at data rates between one and three Mbps. It will
also support services like e-mail, high-speed Internet access,
multimedia applications including streaming video and music, VoIP
and other real-time business collaboration services, in addition to
video surveillance and remote telemetry.
Specifications for the mobile version of WiMAX, or 802.16-2005
(formerly e), were announced at the end of 2005. Expect to see
trials this summer with commercial deployments in 2007. Korea will
be a good place to watch in the coming months as the country becomes
an early-mover with its own homegrown version of mobile WiMAX called
WiBro, short for wireless broadband.
So, how does an enterprise prepare for
By 2008, WiMAX connectivity will be embedded in the base silicon of
most new laptops alongside WiFi as a standard capability. Even
before this, WiMAX will be enabled through laptop cards or dedicated
devices with costs ranging from $100 to $500. The next two years
give IT managers time to ready their networks, taking into account
the security and mobility infrastructure needed to support a broad
range of computing and communication devices that will inevitably
access their systems and applications via multiple public and
private networks. Now is the time to learn about the new
capabilities WiMAX is expected to deliver and invest in a mobility
infrastructure that will anchor WiMAX devices in the home network
and create the service provider partnerships required to enable
public roaming for employees and clients.
WiMAX Delivering A Truly Mobile, Internet Everywhere Lifestyle
WiMAX skeptics contend that the technology has a long way to go and
isnt really necessary given the wireless networks already in place.
No, WiMAX wont change things overnight or immediately have all of
the capabilities that come with a technologies evolution and
maturation. Getting to an Internet everywhere point will take time.
The world experienced a similar evolution with cellular technology.
The difference now expectations are higher. Weve already become so
accustomed to being able to use our mobile phones at any moment,
anywhere. That's only been the norm for the past decade. The next
phase is coming, maybe even faster. WiMAX will be everywhere.
Figuratively speaking, it will leak through the walls. Think now
about how it will impact the enterprise and, as Forbes predicts,
change the way we live it.
