What is wimax, how to use it, how to get started?
WiMAX is defined as Worldwide Interoperability for
Microwave Access by the WiMAX Forum, formed in April 2001 to
promote conformance and interoperability of the IEEE 802.16
standard,
officially known as WirelessMAN. The Forum describes WiMAX
as "a standards-based technology enabling the delivery of last
mile wireless broadband access as an alternative to cable and
DSL".
The IEEE 802.16 Working Group on Broadband Wireless Access
Standards, which was established by IEEE Standards Board in
1999, aims to prepare formal specifications for the global
deployment of broadband Wireless Metropolitan Area
Networks. The Workgroup is a unit of the IEEE 802 LAN/MAN
Standards Committee.
Although the 802.16 family of standards is officially
called WirelessMAN, it has been dubbed “WiMAX” by an industry
group called the The WiMAX Forum. The mission of the Forum is
to
promote and certify compatibility and interoperability of
broadband wireless products. The acronym WiMAX expands to
"Worldwide Interoperability for Microwave Access".
The first 802.16 standard was approved in December 2001 and
was followed by two amendments – 802.16a and 802.16c to
address issues of radio spectrum and inter-operability,
respectively. In September 2003, a revision project called
802.16REVd commenced aiming to align the standard with aspects
of the European Telecommunications Standards Institute
(ETSI) HIPERMAN standard as well as lay down conformance
and test specifications. This project concluded in 2004 with
the release of 802.16-2004 and the withdrawal of the earlier
802.16 documents including the a/b/c amendments.
Amendments to the standard
An amendment to the standard,
IEEE 802.16-2005 (formerly known as IEEE 802.16e), addressing
mobility, was concluded in 2005. This is sometimes called
“Mobile WiMAX”, after the
WiMAX forum for interoperability.
Active amendments:
802.16f – Management Information Base
Amendments in
development:
802.16g - Management Plane Procedures and Services
Amendments at pre-draft stage:
802.16h - Improved Coexistence Mechanisms for
License-Exempt Operation
802.16i - Mobile Management
Information Base
802.16j - Mobile Multihop Relay
802.16k - Bridging
Certification
Because the IEEE only sets specifications
but does not test equipment for compliance with them, the
WiMAX Forum runs a certification program wherein members pay
for certification.
WiMAX certification by this group is intended to guarantee
compliance with the standard and interoperability with
equipment from other manufacturers. The mission of the Forum
is to
promote and certify compatibility and interoperability of
broadband wireless products.
IEEE 802 refers to a family of IEEE standards about local
area networks and metropolitan area networks. More
specifically, the IEEE 802 standards are restricted to
networks carrying
variable-size packets. (By contrast, in cell-based networks
data is transmitted in short, uniformly sized units called
cells. Isochronous networks, where data is transmitted as a
steady
stream of octets, or groups of octets, at regular time
intervals, are also out of the scope of this standard.) The
number 802 was simply the next free number IEEE could assign,
though
"802" is sometimes associated with the date the first
meeting was held - February 1980.
The services and protocols specified in IEEE 802 map to the
lower two layers (Data Link and Physical) of the seven-layer
OSI networking reference model. In fact, IEEE 802 splits the
OSI
Data Link Layer into two sub-layers named Logical Link
Control (LLC) and Media Access Control, so that the layers can
be listed like this:
Data link layer
LLC Sublayer
MAC Sublayer
Physical layer
The IEEE 802 family of standards is maintained by the IEEE
802 LAN/MAN Standards Committee (LMSC). The most widely used
standards are for the Ethernet family, Token Ring, Wireless
LAN, Bridging and Virtual Bridged LANs. An individual
Working Group provides the focus for each area.
General
The IEEE 802.16 Air Interface Standard is truly a
state-of-the-art specification for fixed broadband wireless
access systems employing a point-to-multipoint architecture.
The initial
version was developed with the goal of meeting the
requirements of a vast array of deployment scenarios for BWA
systems operating between 10 and 66 GHz. As a result, only a
subset of
the functionality is needed for typical deployments
directed at specific markets. An amendment is almost finished
to do the same for systems operating between 2 and 11 GHz.
Additionally, the IEEE process stops short of providing
conformance statements and test specifications. In order to
ensure interoperability between vendors competing in the same
market,
the WiMAX technical working groups were created by the
leaders in IEEE 802.16 technology.
The 802.16 standard, amended this January by the IEEE to
cover frequency bands in the range between 2 GHz and 11 GHz,
specifies a metropolitan area networking protocol that will
enable a wireless alternative for cable, DSL and T1 level
services for last mile broadband access, as well as providing
backhaul for 801.11 hotspots. The new 802.16a standard
specifies a
protocol that among other things supports low latency
applications such as voice and video, provides broadband
connectivity without requiring a direct line of sight between
subscriber
terminals and the base station (BTS) and will support
hundreds if not thousands of subscribers from a single BTS.
The standard will help accelerate the introduction of wireless
broadband
equipment into the marketplace, speeding up last-mile
broadband deployment worldwide by enabling service providers
to increase system performance and reliability while reducing
their
equipment costs and investment risks. Overview of the IEEE

APERTO
Aperto Networks has been a leading contributor to IEEE
802.16 and ETSI HiperMAN standards, making sure that key
technical features such as QoS and link adaptation
enhancements
were supported to stringent carrier requirements. Aperto
Networks was the first company to deliver IEEE 802.16-class
systems in 2000.
The combination of standards
completion in March 2003, official launch of the WiMAX Forum
in late 2003, Aperto pushed forward to the development of
PacketMAX – one of the first
systems submitted for WiMAX certification. These efforts
provide a solid base contributing to the ongoing development
of WiMAX products now with outdoor fixed and indoor installed
subscribers based on IEEE 802.16-2004 and evolving to
portable and mobile systems based on IEEE 802.16e in the
future.
Technical Firsts:
First to
implement a carrier-class QoS profiles (up to 16 service
flows) to support simultaneous voice and tiered data services.
First to enable up to six different adaptive link
parameters per subscriber for high throughput, peak
performance, and interference resilience.
First to support
a medium access control (MAC) scheme using burst mode time
division multiple access (TDMA) that can scale from a few
users to hundreds per sector.
First in the industry to
over enhanced IP networking functionality such as virtual LAN
(VLAN) support, IP routing, and Dynamic Host Configuration
protocol (DHCP) server.
Pre-WiMAX broadband wireless providers have often been
constrained by low-level networking and interoperability
issues – limiting their service offerings to raw bandwidth and
basic
Internet access. These providers are realizing that while
the new WiMAX standard helps ensure compatibility, it does not
by itself result in an optimized solution that satisfies the
whole
range of operational and subscriber requirements. Aperto’s
industry-leading PacketMAX™ infrastructure permits service
provides to focus on their key business: offering competitive
and
profitable services. PacketMAX lets providers differentiate
themselves from their competition by delivering the broadest
array of services architected around a fully optimized WiMAX
solution.
Aperto PacketMAX is specifically
designed to enable service offerings that drive revenue. These
services include:
Voice
Can voice be the
“killer app” for WiMAX? There is good reason to believe that
many users will utilize fixed wireless voice as their lifeline
to the outside world. PacketMAX systems leverage
Aperto’s unique quality of service (QoS) features to
delivering best-of-breed voice service offerings. For more
information, Contact Traderock at www.traderock.com .
TDM
Despite the current trend toward IP convergence,
demand for TDM services is still growing. The need for
providers to deliver mobile voice and data drives expenses
upward and increases
operational complexity by requiring rapid deployment of new
cell sites to handle the increased traffic. Many large and
midsize enterprises have sizable investments in TDM-based
systems
for private voice, and must continue to provide
high-quality service. Leased-line costs can account for up to
30% of operational expenditures for mobile operators
backhauling cell site
traffic. PacketMAX technology can dramatically lower these
costs by effectively emulating circuit-switched services over
the lower-cost WiMAX link. For more information, Contact
Traderock at www.traderock.com .
Internet Access
Internet access is an indispensable
part of any service providers’ portfolio. However, customers
differ widely with regard to their precise bandwidth
requirements, their desired level of
service, and their cost sensitivity. PacketMAX can help
operators tailor specific services to the needs of the
customer, extracting the maximum revenue for basic Internet
access. For
more information, Contact Traderock at www.traderock.com .
Differentiated Offerings
The term “convergence” is
quickly becoming a synonym for providing all services over the
wireless link, whether fixed or mobile. This means a single
operator needs to supply voice, video,
and data services to multiple end users simultaneously. In
the case of multiple dwelling / tenet units (MDU / MTUs), the
challenge is even greater because of the need to differentiate
multiple end users attached to the same subscriber station.
The PacketMAX system can help overcome convergence challenges.
For more information, Contact Traderock at
www.traderock.com .
Video
There has been some speculation in the industry
about whether WiMAX can deliver video traffic profitably.
PacketMAX systems help operators leverage the well-developed
IPTV
ecosystem, enabling an end-to-end solution for live or
streaming video. PacketMAX technology overcomes bandwidth /
spectrum challenges to provide a multichannel video service.

(ATCA) specifications
Aperto® Network’s PacketWave® point-to-point product line
features a number of advanced technologies, several of which
were introduced to the point-to-point wireless market for the
first time by Aperto.
Link distance and
spectral efficiency are two of the most fundamental values in
any point-to-point wireless product, and Aperto excels at both
of them. Aperto’s Link Distance is one of
the longest available in its price range. The system gives
the operator the choice to use a variety of antenna types,
thus enabling even larger link distances with higher gain
antennae.
Aperto’s Spectral Efficiency (or how many bits it can pack
in the available bandwidth) is one of the best in the
industry. Up to 20 non-overlapping channels are made available
in the 125
MHz of spectrum in the 5.8 MHz ISM band, as compared to the
4-6 channels available in most other products.
The PacketWave point-to-point product offers a unique
feature that enables the operator to synchronize multiple
co-located point-to-point links. This enables the operator to
do the
following:
Re-use the same channel in
multiple co-located links, under the constraint that any two
links are separated from each other by at least 90 degrees.
For example, using a single 6 MHz
channel, the operator can put up four point-to-point links
at a single location.
If there are multiple channels
available, then several links can be co-located, under the
constraint mentioned above.
Aperto
uses a number of technologies to make the wireless link more
robust to multipath and interference, including:
ARQ or Automatic Re-Transmissions
Adaptive
Coding and Modulation
Automatic Frequency Selection
Antenna Diversity
Working together
seamlessly, these technologies enable the system to keep
operating smoothly, even with packet error rates as high as
5-10%. This enables the system to operate in
OLOS/NLOS environments, as well as in crowded license
exempt frequency bands where Interference is an un-avoidable
fact of life.
Aperto is alone among
broadband wireless vendors in offering a Flexible Channel
Size, which can vary from 6 MHz down to 4 MHz. In license
exempt bands, it increases the number of
available channels and makes it easier for the operator to
find clean chunks of spectrum in a crowded environment.
In addition several tools are provided to
facilitate the configuration and management of each base
station system (i.e. base station, each channel and all SUs
served by this base station).
Those tools include:
The Advanced
Installation Manager to facilitate quick installation and
initial configuration of the point-to-point units. This tool
also enables the installer to correctly point the antenna, by
plotting the received signal and SNR levels. Note that this
pointing can be done at either end of the link.
The
Web-based Graphical User Interface for remote monitoring and
configuration of the point-to-point units.
The Upgrade
Manager (UM) for software upgrade support
SNMP
These tools provide all functionalities to the
service provider to configure, manage, control and monitor
each of PacketWave systems.
An intuitive GUI and powerful tools increase
productivity of network operations centers. With the ability
to discover and inventory equipment in real time, the
WaveCenter EMS system
ensures fast deployment of Aperto equipment and
provisioning of customers. It also provides powerful tools to
ensure robust operation of the wireless network and network
elements and
also accelerates the resolution of problems.
Centralized Network Management
WaveCenter EMS provides
full FCAPS (Fault, Control, Accounting, Performance, and
Security) capabilities making network information easily
analyzable thereby allowing the network
administrator to make fast, intelligent choices.
Information is displayed in intuitive screens while the
underlying real-time and historical performance data gathered
from each device is
stored in a central relational database. WaveCenter EMS
includes an embedded SQL database so no additional software is
required.
Highly Scalable / Distributed
Architecture
WaveCenter EMS employs a highly efficient
IP-based distributed client/server architecture that can scale
to support networks that contain hundreds of thousands of
elements. Such
scalability is achieved by distributing the processing of
EMS software modules (EMS Client, EMS Front End Server, EMS
Back End Server, and Relational Database) across multiple
server
platforms.
Powerful Configuration
Capabilities
Templates can be created to define commonly
used configurations making it easy to quickly rollout new
equipment and customers. Modifications to configurations can
be made either to
individual network devices or “in bulk” to groups of
network devices.
Timely Information Enables
Rapid Response
WaveCenter EMS provides administrators
access to real-time information displayed in either graphical
or tabular form.
Network and RF performance
parameters are closely monitored to achieve maximum usage of
wireless bandwidth and to ensure all customers are receiving
their intended service levels.
Alarms and
events are rapidly processed. Within seconds of an actual
alarm event, multiple WaveCenter EMS clients can see this
information allowing administrators to rapidly deploy
solutions even before the service provider’s end users may
have noticed there was a problem
