Q: Using nBanc, how long does a transaction take?
A: In case of a fresh connection through dialup, there is a delay of thirty
seconds for the connection to be established and authorized. After this
period, there is a real time flow of data and time taken is in direct
proportion to the amount of data being transferred.
Q: How secure is the data being exchanged?
A: All the data flowing through nBanc is encrypted through its passage.
nBanc uses SSL to prevent unauthorized access
Q: Using nBanc, can we provide internet access to the employees?
A: Yes, nBanc can also double as a proxy server, providing internet sharing
to all the nodes in the LAN
Q: If we connect to the internet, how is the security of our servers
A: nBanc can be configured in such a way that a certain set of machines are
accessible only to the intranet users and no data from the internet is
allowed to pass to these machines. This ensures the sanctity of the servers.
Q How is "wireless" Internet access different?
A Instead of using a telephone wire or cable to link the end-user's computer or other communications device to the ISP, wireless Interne access providers use the electromagnetic spectrum, or radio waves, to make that connection. Presently, several different wireless services and technologies are being used to provide wireless Internet access, and many more are being rolled out or tested.In addition, two different types of wireless Internet access have evolved -- fixed wireless and mobile data.
Q What do you mean by fixed wireless Internet
A By fixed wireless Internet access, we generally are referring
to office environments where the end-user utilizes a desktop or
laptop computer that accesses its ISP through a wireless connection.
In most cases, however, this does not mean that the computer will
no longer have a wire hooked up to a jack in the wall. Most fixed
wireless Internet access providers will install a small antenna
at the customer's business or home, and that antenna is then hard-wired
to all Internet user computers in that home or office. (However,
Metricom's Ricochet service discussed below is more of a hybrid
service. It uses a wireless modem, which obviously allows for
mobility within Metricom's service areas.) The following fixed
wireless Internet access providers use various types of new wireless
technologies: 1) Metricom offers its Ricochet "unlicensed" wireless
Internet access via a network of low power micro cells, which
operate in the 902-928 MHz band in three markets and in several
airports and universities. 2) Companies such as MCI, Sprint and
BellSouth have purchased most of the major "wireless cable" operators,
and are now offering Internet access over FCC licensed broadband
wireless MDS (multipoint distribution service) and/or ITFS (instructional
television fixed service) frequencies in the 2.5-2.7 GHz band.
3) CLECs (competitive local exchange carriers) such as Teligent,
Next Link and Win Star also offer Internet access through high
frequency microwave links in the 24, 28, 31 and 38 GHz bands.
Q What do you mean by mobile (data) wireless Internet access?
A A Mobile wireless Internet access refers to Internet access
over devices with no wires attached, specifically cell phones,
pagers, personal digital assistants (PDAs) and other hand-held
devices. The demand for mobile Internet access, and the ability
to send and receive data over these devices is exploding. As a
practical matter, there are a number of issues that arise from
accessing the Internet over a mobile handset, such as small screens,
lower resolution, a limited keypad for data entry and far lower
processing power and memory than desktop or laptop computers.
Consequently, mobile Internet access looks and functions differently
from fixed wireless access, in that mobile Internet access providers
are forced to simplify the presentation and limit the features
offered to the user to those that are most valued. In order to
expedite the deployment of mobile wireless Internet access, several
major players in the wireless and Internet industries created
the Wireless Application Protocol (WAP) Forum, an industry association
that is developing the evolving WAP standard. The WAP is an open
standard that can be adopted by any company that wants to develop
different or competing wireless Internet access products. The
WAP is an Internet Protocol (IP) platform will support all major
wireless standards, such as GSM, CDMA and TDMA.
Q What are some of the pros and cons of wireless Internet access?
A The pros and cons of wireless Internet access essentially are
the same as among wireless services in general. The primary advantages
of wireless Internet access service are: 1) the lower infrastructure
costs associated with building out a wireless system, which translate
to lower cost for the end-user; 2) generally, the ability to provide
high speed internet access to areas where digital subscriber line
(DSL) and/or high speed cable access is not available; and 3)
for mobile workers, the ability to be in touch without having
to be plugged into a telephone line. The primary disadvantages
are: 1) at present, slower data speeds than DSL lines or high
speed cable access; 2) security concerns; 3) "glitches" with service
reliability, as compared with telephone line delivered service,
and 4) depending on the type of wireless Internet access desired,
coverage can be very limited - usually to just major metropolitan
Q Who are the most likely initial wireless Internet access customers?
A Like many service providers in the burgeoning high speed data
market, most fixed wireless Internet access providers are first
focusing on providing service to the small to mid-sized business
market, and eventually plan to offer service to residential customers.
Due to the initial cost, mobile data applications presently are
primarily geared to business customers.
All about WAP
Q What is WAP?
A WAP stands for Wireless Application Protocol, and basically
allows any user of a mobile phone, handheld PC or Personal Digital
Assistant (PDA) to access the Internet. This de-facto global standard
uses an optimized protocol developed keeping in mind the needs
of a mobile user and the limitations in terms of screen size and
access speed of a mobile device. WAP enables faster, secure, reliable
and efficient delivery of relevant information to mobile users.
Q What is a WAP Gateway?
A WAP Gateway basically translates requests from a WAP-enabled
device to the Internet, retrieves the necessary information from
the Web and sends it back to the WAP-enabled device. The information
sent back is compacted by the Gateway to save bandwidth thus enabling
faster mobile browsing.
Q In what way is WAP different from Internet?
A Internet standards such as HTML, HTTP, TLS and TCP are quite
ineffective when it comes to mobile networks. A standard Web page
designed using HTML cannot be displayed effectively on the small-size
screens of pocket-sized mobile phones. Also, the HTTP and TCP
protocols are not optimized for the specific demands of wireless
networks such as intermittent coverage, long latencies and limited
bandwidth. Therefore, wireless services using these protocols
are often slow, costly and very difficult to use. WAP, on the
other hand, uses binary transmission for greater compression of
data, and is thereby optimized for long latency, low power consumption
and low to medium bandwidth. The Wireless Markup Language (WML)
language used for WAP content, is simpler and more strictly defined
than HTML. WML makes optimum use of small screens and allows easy
navigation with one hand without a full keyboard, and has built-in
scalability from two-line text displays to full graphic screens
on smart phones and communicators. WML, in fact, has its own bitmap
format too for the mobile users - the Wireless Bitmap Format (WBMP).
A user with a WAP-enabled device normally dials-in to a WAP Gateway
service provider. The Gateway, on authentication of the user,
thereafter handles requests from the WAP-enabled device, translates
these requests to Web related protocols, retrieves the necessary
information and sends it back to the mobile user. The cellular
phone or any other mobile device thus acts as a simple web browser,
but optimizes the markup language, scripting language, and the
transmission protocols for wireless use. The optimized protocols
are translated to Web-standard Hyper Text Transfer Protocol (HTTP)
by the WAP Gateway.
Q What is a WAP-enabled device?
A All mobile phone, handheld PCs, pagers, smart phones, two-way
radios, and PDAs, with built-in processors, that enables access
to and transfer of information using Wireless Application Protocol,
are WAP-enabled devices.
Q Can I use my normal mobile phone to connect to the Wabot.com
A Wabot.com is a gateway for WAP-enabled devices. Therefore, at
present, only such compliant devices can connect to Wabot.com.
Q Can I use my mobile only to connect to the Internet?
A WAP has many other applications as well. For instance, you can
also use WAP to set up a corporate WAP gateway for Intranet purposes,
and using your mobile device connect to the Intranet while on
Q Is there a difference in viewing with different WAP-enabled
A Each WAP-enabled device has a different screen size. While most
WAP pages are optimized for 48 x 96 pixels, in certain devices,
this may lead to having to scroll to access all the services.
(See section WAP Devices you can buy).
Q How will WAP benefit me?
A The potentials of WAP are unlimited. At the simplest level,
you can gain access to email and browse the WAP compliant web
sites on the Internet using your mobile device. With content providers
also showing interest in WAP technology, you will have privilege
to regular updated information like stock ticker, ticketing and
reservation, weather and traffic details.
Q Can I browse the Internet using a WAP-enabled device?
A Web pages on the Internet are developed using HTML, which is
not compliant with Wireless Application Protocol. WAP uses a separate
markup language called Wireless Markup Language (WML). Therefore,
all pages on the Net, which are created using WML can be viewed
using your WAP-enabled device. A useful search engine to search
for WAP-enabled pages is www.wapaw.com.
Q Can I view images on my cellular phone?
A The WAP specifications allow for the use of a graphics format
called WBMP (Wireless Bitmap Format). It is a 1 bit (either black
or white) version of the BMP format. However, there are certain
limitations with the WBMP format, mainly that the image size cannot
exceed 150 x 150 pixels, but then most cellular phone screens
are smaller than this.
Q How fast can I surf using my WAP-enabled device?
A The Wireless Application Protocol allows for a speed of 9,600
bps. That means, you can easily download your text-based e-mails
within seconds. Sites using Wireless Markup Language are optimized
for wireless application protocol and therefore can deliver content
faster to the WAP-device.
Security and Privacy
Q How secure is the information I transmit using Wabot.com?
A All information transmitted through your WAP-enabled device
is encrypted during its passage. Like HTML, the Wireless Markup
Language also uses security features like WTLS, thereby preventing
Q Can anyone track my Net usage and phone number when I connect
A Data transmitted through the Wabot.com Gateway is encrypted.
While handling requests from the mobile device, Wabot.com ensures
that all header information, which may contain information regarding
the user, is removed. This ensures that no one can track your
mobile phone number or Net usage.
Q Can I receive junk/spam messages on my mobile while browsing
A Wabot.com acts as a Gateway translating information from the
Internet to your cellular device.
