Objective:
WML is ideally
suited to ILECS, CLECS, 15Ps and Enterprises wishing to roll out
high-speed, highquality IP based services to high-end residential,
SOHO and business users.
Here are some of the applications of
WML:-
High-speed data
WML customers can enjoy
the benefits of highspeed, 'always-on'data access thanks to having
burst rates of up to 4 Mbitls - 80 times faster than the fastest
dial-up PSTN modem.
WML uses available sector bandwidth
intelligently: Bandwidth is assigned only when there is a data
packet to transmit. With WML, it is possible to take advantage of
statistical gain over the air interface and oversubscribe the
available bandwidth without degrading the delivered
performance.
High-speed lnternet access
One of
the advantages of WML is that users are 'always on': there is no
need to dial-up the service provider first, making it easier and
more fun to access the Intemet.
Users need only open their web
browser or e-mail program to be instantly connected.
WML can
also distinguish between applications and users, enabling the
operator to provide different classes of service to
users.
VOIP
WML provides a solution for voice
as well as data.
Standard telephone instruments are connected to
a Integrated Access Device (IAD) which in turn communicates over WML
with a Media Gateway (MG) connected to a Class 5 switch. Thanks to
its open architecture, WML is able to interwork with a number of
third party IAD and MG products on the market today, supporting a
range of protocols (H.323, MGCP and SIP), as well as a range of
voice coding standards (G. 71 1, G. 723, G.
729).
Multimedia over IP
The fact that WML can
provide up to 4 Mbitls of throughput to the user together with its
ability to set different priorities to different applications and
provide QoS, make it a good solution for enabling services such as
video-over-IP and good quality videoconferencing.
The system can
prioritize video packets in such a way that delays and jitter are
minimized and the video packets pass smoothly through the
system.

Private networks
WML can be used
in enterprise networks and campus networks.
In this
application, WML is used to construct a private network, which
allows high-speed data, voice and multimedia services amongst
its users, as well as being connected to the public network
over an industry-standard interface such as 10/100 BaseT
Ethernet.
Thanks to its advanced software features WML can
be used in creating secure, virtual private networks (VPNS)
between the different locations of an
enterprise.
Different Network
topologies
WML has been deployed in many ingenious
ways around the world.
In addition to the well-known PMP
cellular deployment, WML 85 radios have been deployed at
street level, along electricity poles linked together by
optical fibre, WML radios have been used for backhauling their
own traffic and indoor coverage has been achieved by placing
85 radios on adjacent buildings.
WML Management
System
WML is managed by WManage, the WML element
manager, which runs on a standard Microsoft Windows platforms
(Windows NT or 2000).
and incorporates a user-friendly
graphical user interface (GUI). WManage is based on the
industry standard Simple Network Management Protocol (SNMP)
and provides a comprehensive range of management
functions.
It enables trap management, configuration
control, fault isolation, performance monitoring and remote
software download.
WManage can access each BS and ST unit
in the system and manage it remotely using standard SNMP
protocols plus private and standard M1Bs for setting and
retrieving parameters from the units.
The top hierarchy of
WManage is a BS site view from which one can zoom into every
ST. |
