WAP: opening new channels Wireless Application Protocol will power
mobile e-business. Paul Mason outlines the issues for early
adopters
What is Wap? Wireless Application Protocol is an international
standard for transferring Internet content to mobile phones and
palmtop computers. It will allow the recently-launched Wap mobile
phones to browse the Internet.
Why is it important? One in four adults in the UK owns a mobile
phone. If Web-style content and services can be beamed direct to
their handsets, a whole new market for mobile e-commerce will take
off. ARC Group predicts that the number of mobile e-commerce users
will overtake the number buying from their desktop PC by early
2003. By 2005 there could be one billion mobile phone users
worldwide.
What does it mean for e-business?
More customers, different behaviour. Today, e-commerce
relationships are shaped by the way PCs access the Web. Mobile
phones are not static and private - they allow anytime, anywhere
access. Mobile Internet access is typically done over equipment and
bandwidth paid for by the end-user. Unlike a PC a mobile phone is
always on or can be quickly switched on. Web buying behaviour today
mirrors mail-order purchasing. Mobile e-commerce will not just
mirror High Street behaviour - it will dovetail with it.
What services could I provide using Wap today?
The first six months of 2000 will see the UK's four mobile
networks team up with handset manufacturers to roll out basic Wap
phones and services. Pilot schemes include: online bank account
management; mail-order CD purchase; frequent flier flight booking
and realtime financial market news. But although the phones are
available in the High Street, fully-fledged services and content
are thin on the ground
What is the main business issue?
The changed relationship between content provider, network
carrier and hardware manufacturer. The Internet was constructed on
stable technology - the PC, the modem and the landline telecoms
network. The mobile Internet is being constructed on new technology
- Wap-enabled GSM networks dominated by telecoms giants. The mobile
network carriers are shaping the content - ie the business
opportunities - far more heavily than the early Internet service
providers. So, the mobile Internet will start off as a highly
monopolised sector of the online economy. If you want to provide
e-business content - such as a retail or entertainment services,
you could be forced into partnership with a proprietory domain
dominated by a handset or network company.
What is the main technical issue?
Slow connection speeds. Today's GSM phones transfer data at
9.6kbps, whereas a PC modem speed has a maximum of 56kbps, and
two-line ISDN allows 128kbps.
Will it get faster?
Yes. Today's GSM phones will soon be replaced by phones using
GPRS technology at 115kbps. This is better than ISDN but well below
the ADSL landlines being rolled out in parts of the UK by BT this
month. So for the forseeable future Wap content will have to be
significantly less flashy than wireline services. That means the
simplest transactions - booking systems, online payment, mail order
and gambling - will be the easiest to deliver. Anything reliant on
visual content will be much harder. The wait for GPRS phones may
actually retard the uptake of Wap-enabled GSM phones and
devices.
What are the staffing issues?
Wap has created an instant skills shortage. Wap engineering
skills belong to the telecoms domain. Firms who want to provide
services, sell products or organise their workforce over the mobile
Internet will need specific content authoring skills. Wap content
is written in Wireless Markup Language (WML), a special subset of
the Internet language SGML. Needless to say, WML Web authors are in
short supply.
Can I reuse existing Web content over Wap?
Not yet. It needs reformatting. You do not need to have two
separate URLs as it is possible to determine whether the user has
hit the site using a mobile phone or a PC, and direct the query to
the relevant version of the content. Another content issue is Java.
JavaScripts are used to make HTML pages interactive. A similar
scripting language exists called WMLScript, but these scripts sit
outside to the main Web page and have to be accessed
separately.
What is being done to help me "re-purpose" content for
Wap?
The World Wide Web Consortium, the guardian of Internet
standards, is working on a future markup language called eXtensible
Style Language, that would allow a one-off generation of content
via XML, which is then filtered towards WML, HTML and hard-copy
output.
Is Wap secure?
The software is as secure as the rest of the Internet. But, all
security relies to some extent on hardware security and customer
behaviour. Mobile phones are a well known target for criminals and
the prospect of one-touch access to personal bank account, credit
card payment or stock trading will present an inviting target.
Firms providing mobile e-commerce will have to do more than the
current fixed wire e-services have done to assure trust in the
market.
Who will be the early adopters of mobile e-business?
Banks and credit card companies, firms whose transactions
involve booking and ticketing, mail order firms whose products can
be sold over text-heavy channels or linked to the voice
capabilities of the phone.
It uses the Internet standard Transport Layer Security (TLS)
protocol.
Who owns WAP?
Wap is a de-facto international standard - it is not yet policed
by a statutory standards body. HTML, along with the Internet in
general, is policed by the World Wide Web Consortium. Wap on the other hand
is developed and standardised by an industry body with 200 global
affiliates, the Wap forum. Wap version 1.1 is the current
standard Version 1.2 is currently under discussion.
