Always-on' means that the WiMAX broadband sets up a permanent connection to the Internet
that lets you access the Internet as soon as you switch on the computer and the modem.You do not need to 'dial up' like when you are using a standard modem connection.
When the information flows from somewhere e.g. a web-page or a site to your PC you are "downloading" on the other hand when you send information e.g. request for a web-page, you are "uploading"
After switching on the modem, you can access Internet with the Browser (Internet Explorer).
You are provided with a Pre-Configured modem where the username and password are pre-coded
on the modem
One GB is 1024 Megabyte or 1048576 kilobytes. You can possibly do the following with 1 GB download limit :
»
An average web page is about 50 kilobytes in size - so you could download around 20,000
web pages for 1 GB.
»
An hour of surfing the web would be around 20 MB (100 pages) so you could surf non-stop
for about 100 hours for 1 GB.
»
An hour of streamed radio would use about 15-20 MB.
»
An hour of streamed video uses around 100-150 MB.
»
Playing an online game typically uses about 10-15 MB per hour.
»
Emails are very small - so 100 emails would be just 1 MB - or 100,000 emails for 1 GB!
(of course the attachments weigh extra)
»
A super-high resolution (5-6 megapixel) digital camera JPEG picture or typical MP3
music file is about 2-3 megabytes so you could download 350-500 of these images/music files
for 1 GB.
»
The above are all illustrative approximations and very few users may actually exceed the
1GB download unless they have real bulk internet usage.
IP addresses are analogous to telephone numbers – when you want to call someone on the telephone, you must first know their telephone number. Similarly, when a computer on the
Internet needs to send data to another computer, it must first know its IP address.
IPaddresses are typically shown as four numbers separated by decimal points, or “dots”.
For example, 10.24.254.3 and 192.168.62.231 are IP addresses.If you need to make a
telephone call but you only know the person’s name, you can look them up in the telephone
directory (or call directory services) to get their telephone number. On the Internet,
that directory is called the Domain Name System, or DNS for short. If you know the name of
a server, say www.metamax.in, and you type this into your web browser, your computer will
then go ask its DNS server what the numeric IP address is that is associated with that
name.
Every computer on the Internet has an IP address associated with it that uniquely identifies
it. However, that address may change over time, especially if the computer is

The standard broadband technologies in most areas are DSL and cable modems. Newer technology
in use is WiMAX, giving the customer freedom from Overhead wired Internet Connections.
WiMAX based Fiber-optic communication, has played a crucial role in enabling Broadband
Internet access by making transmission of information over larger distances much more
cost-effective than copper wire technology. In a few areas not served by cable or ADSL,
community organizations have begun considering to install WiMAX networks.
A dedicated broadband router is a much better approach when more than two computers need to
share one broadband Internet connection. With this method, all computers on the network are
connected together using a switch (or hub), and the switch is connected to the broadband
router. All the computers can then connect to the Internet using the router as a gateway.
All routers provide a degree of network security through a technology called Network Address
Translation or NAT. NAT means that computers on the Internet can only see your router, and
they cannot gain direct access to your own computer. Broadband routers usually have no
moving parts in them (i.e. a disk or fan), so they are silent in operation and hardly ever
fail.
Setting broadband routers up is usually a straight-forward process too. Most will
automatically detect the necessary settings, and they will usually set up your home
network for you too (using a technology called Dynamic Host Configuration Protocol or DHCP).
As the name implies Static IP addresses are the same every time you connect. dynamic IP
addresses may change each time you connect to the network (e.g. Internet).
From a business deployment standpoint, WiMax is essentially a replacement for the wire line
Internet connectivity method. It's a new method of delivering Internet to a facility or a
customer's premises in a reliable way without wires, T1, DSL or cable. Whereas WiFi is for
local hotspots, WiMax has medium bandwidth as well as ten Mbps of bandwidth for a local LAN
connection. WiFi is for a LAN, and WiMax is for the WAN but is much faster and can get up to
gigabit speeds and licensed spectrums. WiMax can run on a licensed or unlicensed spectrum
and WiFi is exclusively unlicensed on a fixed number of channels. Following recent protocol,
WiMax also takes in the new standard 802.16 vs. 802.11..The idea is that you could deploy
much faster than with traditional land lines and attain much more flexible bandwidth.
Rather than have a phone company come out and provide you with wires and equipment, the
company turns up the broadband on their end. Basically, WiFi is access to a LAN, and while
WiMax can be used for that, one of its most beneficial uses is as a fixed wireless solution.
You will be getting Limited or no Connectivity or Acquiring Network Address message When
the LAN card is not getting any IP from the nearest DHCP Server. So please follow the
guide lines as below:-
»
Re-check the Cables by unplug and plug it back.
»
Disable and enable the LAN Card.
»
Update the LAN Card Drivers.
»
Open the command prompt and typeipconfig/release and then type ipconfig/renew.
»
Right click on the LAN card and select Repair.
»
Finally Restart the computer.
»
Please check with your Administrator when connected in LAN.
A leased line is a private high-performance circuit leased by a common carrier between a
customer and a service provider's network. It is rented on an annual basis and usually
carries voice and data or both. CPNS (Clearpath Network Solutions) are mostly used for either Internet access or
used privately between two customer sites. Unlike a dial-up connection, a leased line is
always active. Similarly unlike broadband, a leased line is not contended or shared and
delivers dedicated guaranteed bandwidth straight to the Internet backbone. Customers pay a
premium for a leased line and it is supported by a comprehensive Service-Level Agreement
(SLA) with a guaranteed fix time and a compensation clause. Otherwise referred to as a
point to point, private circuit, private line or dedicated access.
The Firewall is defined as "a system or group of systems that enforces an access control
policy between two networks." In the context of home networks, a firewall typically takes
one of two forms:
»
Software firewall - specialized software running on an individual computer, or
»
Network firewall - a dedicated device designed to protect one or more computers.
For Home users, typically, the Internet is used for browsing, Simple downloading, e-Mail
and Voice Chat. The speeds can range between 128 kbps to 1Mbps. The connection can be
Limited or Unlimited as per the time spent on the Internet. The right choice would be True
Broadband.
For Business Users, the Internet is used for Business transactions, Heavy File Downloading
sometimes, a persistent Internet Connection for Client Meetings etc. An Unlimited and fast
WiMAX Broadband connection is the need of the hour for the Businesses. The right choice
would be "Business Class" Broadband .
You can check your bandwidth utilization reports in the Personal Usage portal provided by
MetaMAX for your User Connection. The details are provided once you are a customer
If you feel that you need more than what you are getting currently or your usage is going

WiMAX is an IP based, wireless broadband access technology that provides performance similar
to 802.11/Wi-Fi networks with the coverage and QOS (quality of service) of cellular networks.WiMAX is also an acronym meaning "Worldwide Interoperability for Microwave Access (WiMAX).
Since much of the technology being utilized in the IEEE 802.16 standard (WiMAX standard) is
widely deployed, there is a historical body of evidence supporting the safety of
technologies used in upcoming WiMAX. Microwave and other spectrum technologies enjoy over
a hundred years of historical evidence of safety when prudently handled and configured.
The amount of power allowed to deliver broadband wireless signal varies from frequency to
frequency, however, most are modest topping out at around 40 watts at the tower relay site.
While certain basic precautions need to be taken when onsite at communications towers
(i.e. standing directly in front of active microwave links at essentially zero range) the
configurations for public use are understood and safe. Customer premise equipment is even
safer.
It is important to remember that WiMAX is a global broadband wireless standard.
The question of whether or not it could replace either DSL or Cable will vary from region
to region. Many developing countries simply do not have the infrastructure to support
either cable or DSL broadband technologies. In fact, many such countries are already
widely using proprietary broadband wireless technologies. Even in such regions however,
it is very unlikely that either Cable or DSL technologies would disappear. The business
case and basic infrastructure often dictates that the cheapest solutions will predominate.
In many areas in developing nations, it may be cheaper to deploy Cable and DSL in the cities
at least for fixed applications, whereas WiMAX will dominate outside of major towns.
In India, both Cable and DSL are growing extremely fast, but are not available for all
customers. Rural and remote areas often lack broadband choices if any are available at all.
When they are available, the DSL or cable plant may only exist within the town limits with
no service outside the city limits. This offers a compelling argument that low-cost WiMAX
gear can leverage access to many new customers. WiMAX also promises a whole new level of
data access flexibility that will be much less location specific for customers. This type
of robust mobile, portable or fixed broadband access will be unprecedented.
In addition, WiMAX will provide competitive options for carriers and users that will benefit
traditional wireline carriers and customers by encouraging innovation and improved services.
With the advent of IPTV fiber plays are enjoying resurgence. It does not appear that WiMAX
or broadband wireless will be ready to deliver IPTV in the immediate future. However,
fixed WiMAX may offer the best potential for delivery of this potential content juggernaut.
More recently some promising new compression technologies have reached the market. These
technologies, while still new, allow the delivery of true IP-based TV signals to cellular
devices. One company asserts that it could deliver high definition TV (HDTV) in as little
as 2.5 Mbps of bandwidth, with standard resolution signal requiring 1.5 Mbps. These speeds
are within the potential reach of WiMAX.
The answer to this question probably generates more confusion than any other single aspect
of WiMAX. In the early days of WiMAX it was common to see statements in the media
describing WiMAX multipoint coverage extending 30 miles. In a strict technical sense
(in some spectrum ranges) this is correct, with even greater ranges being possible in point
to point links. In practice (and especially in the license-free bands) this is wildly
overstated especially where non line of sight (NLOS) reception is concerned.
Due to a variety of factors, the average cell ranges for most WiMAX networks will likely
boast 4-5 mile range (in NLOS capable frequencies) even through tree cover and building
walls. Service ranges up to 10 miles (16 Kilometers) are very likely in line of sight
(LOS) applications (once again depending upon frequency). Ranges beyond 10 miles are
certainly possible, but for scalability purposes may not be desirable for heavily loaded
networks. In most cases, additional cells are indicated to sustain high quality of service
(QOS) capability. For the carrier class approach, especially in regards to mobility, cells
larger than this seem unlikely in the near future.
WiMAX supports very robust data throughput. The technology at theoretical maximums could
support approximately 75 Mbps per channel (in a 20 MHz channel using 64QAM ¾ code rate).
Real world performance will be considerably lower---perhaps maxing out around 45 Mbps/
channel in some fixed broadband applications. Remember however, that service across this
channel would be shared by multiple customers. Actual transmission capabilities on a per
customer basis could vary widely depending on the carrier's chosen customer base, which is
actually an inherent strength because it can be defined by QOS in a deliberate fashion to
offer different bandwidth capabilities to customers with different needs
(and different budgets). WiMAX is often cited to possess a spectral efficiency of 5 bps/Hz,
which is very good in comparison to other broadband wireless technologies, especially 3G.
The physics of frequency range plays a powerful role in bandwidth capability.The higher the
frequency, the greater the bandwidth delivery potential and the shorter range potential.
Lower frequencies enjoy much greater range capability, but trade that off with much lower
bandwidth potential. Fortunately, even with disclaimers centered on real world impediments,
WiMAX throughput is excellent. Perhaps no litmus test is as good as the results that
carriers report and several carriers have shared that they are consistently achieving as
much as 5 Mbps download speeds.
The short answer is yes, as never before with broadband wireless systems.However, this area
appears to be early ground that vendors are staking out to differentiate their products and
philosophies. The WiMAX standard itself incorporates much better and more flexible security
support than the Wi-Fi standard. It can be sometimes confusing when industry pundits and
detractors talk of standards such as WiMAX and then in the same breath describe ways in
which vendors will be "different" or that WiMAX security might be weak. At first glance,
these comments on the part of some vendors zealous to promote the added capabilities of
their products can leave one feeling uncertain about the quality and reliability of the
product.
Security is probably a good place to explain the difference between the very robust base
standards of WiMAX and the ways in which individual vendors can still differentiate their
products (with additional and perhaps more powerful or convenient features) beyond the
features that the base standard offers. However, what is important to understand is that it
is quite robust. Perhaps more importantly, it allows for additional feature sets that could
be added by various vendors to achieve security results as good as or better than any
completing wireline broadband option even those being used for extremely secure governmental
applications. Typical residential service does not require the kind of security a bank,
hospital or government often needs. WiMAX can handle this.
An example can be helpful here. Let us say that a broadband wireless service provider
chooses one particular customer premise equipment (CPE) radio that has nice features and an
especially good price for its consumer based offering. These CPEs possess normal WiMAX
security functionality which is at least as good as other broadband consumer technologies
such as cable. It might choose to utilize a second vendor's base station to feed service to
those radios that also possesses enhanced security capabilities adding an additional
security overlay to the base security of the residential network consumer purposed CPE
radio particularly in the backhaul portion of the network. This could add a small layer of
additional support to radios that, while secure, could not feature enhanced capabilities
due to the cost factors that consumer radio business requires.
This same base unit could also offer the company an ability to support an additional layer
of radios for business or governmental or health care industry customers, where health
insurance privacy and portability act (HIPPA) confidentiality compliance is of great
importance, that actually have a DIFFERENT CPE radio that, while more expensive, possesses
feature sets that take full advantage of extended security features that are commonly added
to high-security government networks. It does not detract from the network for perfectly
serviceable residential class security capable (and inexpensive) radios to coexist with
premium feature (and cost) WiMAX products on the same network designed to serve specialty
customers. This approach is similar to add on products used with wireline products that
often require additional hardware beyond the modem.
In fact, as the economies of scale for WiMAX are realized through volume manufacturing,
second generation, high-security products may actually be cheaper than first generation
consumer grade units granting carriers enhanced service margins for high-value services.
Step 1 – Make sure the equipment is connected to power and is responding to the network transactions
Step 2 – Make sure your username and password are still correct. These are usually entered
through a connection program that MetaMAX provided. You will probably have to retype your
password, as you won't be able to read it on-screen
Step 3 – Locate the TCP/IP settings for your computer. In Windows, these are found in the
Network and Dial-up Connection control panels. In Mac OS 9.2 and earlier, they're in the
TCP/IP control panel. In Mac OS X, they're in the Network section of System Preferences
Step 4 – Check that the host name and domain name information are correctly entered in the
TCP/IP settings. This information should have been supplied by MetaMAX
Step 1 – Call MetaMAX's support number to find out if you have been affected by a service outage.
Step 2 – Unplug the power from your modem (whether it's telephone, DSL or cable) for at
least 10 seconds, shut down your computer, plug the modem back in and restart your
computer
Step 1 – Power cycle the system by shutting it down and switching it on after at least thirty seconds.
Step 2 – Check network settings to verify the IP address and other related information.
Step 3 –Determine if the network card is working adequately. Identify the malfunctioning adapter by
disabling the cards one by one.
Step 4 –Move one of the portable hosts--such as a laptop--closer to the router. If it works etter,interference or low signal strength is the reason for poor Internet access. Inadequate
signal performance can be caused by several factors including cordless devices working
within the frequency range (2.4 GHz) of a wireless network, shiny surfaces and too much
distance between hosts and access points. Resolve this issue by using a wireless
repeater-a device that amplifies wireless signal so it reaches distant areas within the
premises. Minimize signal interference by maintaining a distance of at least one meter
between cordless devices and the router. Alternatively, buy gadgets that function at
frequencies other than 2.4 GHz. Try changing the WiFi channel for better results.
Step 5 –Check the functioning of wireless router and access points. Adjust the router antenna to
get an optimum signal. Most wireless routers come with omni-directional antennae to send
signals in all directions, a situation appropriate for a square-shaped network.
Step 6 –Change the location of the router and access point. They should ideally be placed centrally
between all computers. As the signal bounces off smooth and shiny surfaces, routers and
access points should be placed away from windows, doors, mirrors and other metallic
surfaces.
Step 7 – Examine signal performance by using the monitoring utility that typically comes with the access point.
Step 8 –Check that the devices show correct lights. Device lights are an indicator of accurate
connections. Different lighting patterns indicate different things. For example, some
network cards show green light on successfully establishing a connection. Similarly, the
router's wireless LAN (WLAN) light is turned on at all times, even if no device is connected
to it. Further, this light blinks when a host communicates with another host. Unexpected
lighting indicates a problem. Go through user manuals to get familiar with this feature and
make sure the devices show desired lighting behavior.
Step 9 –Use wireless Internet utilities to check the SSIDs and channels neighboring wireless
network are using. Change your network's SSID and/or channel if they are the same as that
of other networks in the vicinity.
Step 10 – See if correct drivers have been installed
