Smaller organisations do not have the luxury of piloting
every new piece of technology that comes along to see how the
business can benefit. But with so much change in mobile technology,
it would appear that IT directors at small to medium-sized
enterprises (SMEs) have the challenge of spotting viable technology
on which to base their mobile strategy.Business cannot afford to ignore mobile technology. “Mobility
can increase productivity, by allowing employees to do the same
things they did before in the office, but on the move. From top
executives to the field force, there are massive cost savings and
competitive advantages to be gained from mobilising the work
force,” said Sylvain Fabre, research director of the Communications
Group at analyst firm Gartner.
However, many SMEs are still struggling to get a handle on
technologies such as 3G, Bluetooth and Wi-Fi, and how they fit with
their business goals.
One of the most visible examples of emerging mobile technology
is the steady growth in network bandwidth in recent years, from
second generation (2G) networks, to GPRS (2.5G) and more recently
3G.
Each step has brought greater network bandwidth for transmitting
voice calls and data files to and from mobile devices. However,
just as users have become au fait with 3G, so HSDPA (high-speed
download packet access), or 3.5G, is already being introduced by
operators around the world.
3G potentially offers transfer rates of 2 megabits per second
(in reality, rates are much lower), but HSDPA offers up to six
times that speed. Many operators upgraded their networks in 2005 to
support HSDPA, but the technology is backwards compatible.
As of April, there were 79 HSDPA networks either built or being
built in Europe, Japan and the US, with more expected throughout
the year.
Operator O2 launched the UK’s first HSDPA service in the Isle of
Man in November, while Vodafone is currently running a trial of its
service with 100 London-based business users accessing it via the
company’s Mobile Connect laptop cards. Vodafone plans to introduce
HSDPA throughout the South East in mid-2006.
Devices too are quickly being HSDPA-enabled. Dell expects to
launch an HSDPA-equipped notebook in June, while Lenovo has
integrated Vodafone’s Sierra Wireless HSDPA card into its new
Thinkpad T60 and X60 notebooks.
The company announced in January its plans to integrate
the card in both notebooks, and the HSDPA has been available since
the Vodafone release in May. The notebooks also boast 11-hour
battery life.
Wireless phones are slightly further behind, although handset
manufacturer Samsung demonstrated the world’s first HSDPA call on a
mobile phone in January, while BenQ Mobile expects to bring the
first device to market in time for the World Cup in June.
“HSDPA is on the way. Initially it will target high-use areas,
such as city centres, but operators will gradually expand their
footprint,” said Fabre, who believes that rather than replacing
voice calls on the cellular network, HSDPA will become a
wider-ranging alternative to Wi-Fi for downloading large files.
“Most likely, it will be used by laptop users, who will go to an
HSDPA coverage area, and stop to download a file. In this way, it
could free up capacity for voice calls on the 3G network, for
example,” he said.
A further network upgrade – known as HSUPA – high-speed uplink
packet access, or 3.75G, is also expected within the next 12
months. HSDPA is not efficient at uploading large files to mobile
devices. “HSUPA makes sending files from a mobile device much
faster,” said Gavin Patterson, principal analyst at communications
research house Informa.
Network equipment is expected at the end of 2006, with laptop
cards not likely before early 2007, and handsets in mid-2007.
Yet another technology to consider is Wimax, which takes the
concept of the Wi-Fi hotspot one step further. It extends coffee
shop or airport lounge hot spots to a matter of kilometres, and
also provides faster transfer rates.
Wimax, or IEEE 802.16, comes in two flavours: fixed and mobile.
Fixed Wimax, known as 802.16-2004, is already available, and is
largely used as an alternative to wireline access – for example, in
a large indoor area where wiring might be difficult or
expensive.
Mobile Wimax, meanwhile, will not be available for at least a
year, but could rival the cellular network for accessing and
sending data. Intel has said that a Wimax laptop card will be
available later this year. Samsung, meanwhile, recently
demonstrated its M8000 Wimax mobile handset – currently, however,
it can only be used in Korea.
With so many alternative approaches to wireless connectivity,
the SME IT director has a challenge deciding which one to adopt.
Luckily it is possible to avoid the technological bickering and to
some extent future-proof a mobile strategy by avoiding embedded
components.
Analyst Gartner recently advised users to avoid buying Wimax or
HSDPA cards that are embedded into laptop devices. Using removable
or plug-in PC cards means that companies can upgrade or replace
technologies as required, by changing the card.
While network bandwidth increases inexorably, devices are also
seeing rapid advances, especially in the area of fixed-mobile
convergence. BT’s Fusion service, for example, provides a handset
that operates as a traditional phone in the home or office, with
calls charged at the standard fixed line rate, but switches to the
Vodafone cellular network outside the building,
acting as a mobile phone. It means one device, one phone number and
one bill.
Equally, mobile phones are now available that switch between
cellular networks such as 3G and IP-based wireless Lans, or Wi-Fi
networks, when the user enters, for example, the office.
“Mobile phones are now available that operate on the cellular
network but switch to the wireless Lan inside the office, where
they can replicate all the traditional telephony functions of the
PBX, such as voicemail, redirecting calls, and so on, as well as
providing mobile e-mail,” said Tony Cripps, principal analyst at
Ovum.
“It offers a single device and a single phone number, and
low-cost calls in the office. It also means that the mobile phone
is arguably becoming a more important device than the desktop PC,
especially for jobs that require a lot of time on the road.”
Last October, Nokia released its E-series handsets – E60, E61
and E70 – designed specifically with this in mind. Similar devices
include Sony Ericsson’s P-Series smartphones and O2’s XDA Exec.
This ability to download larger files has also driven the need
for greater storage on mobile devices. As a result, mobile phones
with hard drives have started to hit the market.
Another technology to look out for is smartphones with embedded
hard drives. These enable the user to store large files and
e-mails, without the need to carry around a number of different
storage cards or media.
Handset manufacturer Samsung unveiled the first mobile phone
with a hard drive, the PH-V5400, in 2004, which contained a 1-inch
1.5Gbyte hard drive. By March this year, however, the Samsung
SGH-i316 phone was offering an 8Gbyte hard drive – it should be
available in European markets in the second half of 2006.
Nokia’s N91, which features a 4Gbyte hard drive, is already
available – however it has been designed as a music player rather
than an enterprise device.
With more data stored on a single device, security becomes
paramount, which is driving the growth of devices with embedded
biometric fingerprint scanners. HP was the first to introduce a
biometric-enabled PDA.
Laptops with the technology include models in the following
ranges: HP Notebook, Lenovo Thinkpad, Dell Latitude, Sony Vaio,
Fujitsu LifeBook and Toshiba Tecra. LG’s LP3550 mobile phone,
meanwhile, is one of the first to incorporate the technology.
But perhaps one of the most important advances in mobile
technology will continue to be the extension of battery life,
without which all of these applications or services are essentially
useless.
An alternative to existing lithium ion batteries are fuel cells.
Last November, Hitachi and Toshiba exhibited their latest
developments in fuel cells for mobile devices, known as direct
methanol fuel cells (DMFC), with Japanese operators KDDI and NTT
DoCoMo interested in developing the technology.
Fuel cells are also appearing in laptops, with IBM and Sanyo
developing a prototype DFMC system for the ThinkPad notebook
range.
However, there are lingering doubts around the safety of
methanol, and whether fuel cells will remain a niche product.
Research company Nanomarkets, for example, claims that while the
market will be worth £850m by 2010, 80% of these fuel cells will
still be used in conjunction with traditional batteries.
Other technologies in development include solar-powered chargers
that top up battery life in the field – although there are large
efficiency improvements to be made. For now, improvements are
focusing on maintaining the significant advances that have already
been made in extending the life of traditional batteries.
A peek over the mobile technology horizon may at first appear
daunting, but for those that are still grappling with the
intricacies of 3G and Wi-Fi, Fabre offers some sound advice: “Don’t
build a mobile strategy around HSDPA or Wimax – there’s currently a
lot of technology disruption out there, so it might be better to
use this to your benefit and focus on negotiating a better deal for
the existing mobile technologies and services.”
