Laptops are about making
Technology & the Internet work for you!
Laptop computers are
replacing bulky desktop machines allowing Telecottage clients to create
documents, hold meetings away from the office, access email &
browse the Internet wherever they want.
Personal Data Assistants
provide up-to-date Contact & Calendar information for mobile clients.
Blackberry PDAs can also provide up-to-date email access using 'push
technology'.
Mobile Phones have gone from being an executive toy to a
necessity used by three quarters of the population for voice, text
& image communication. Modern mobile phones can provide broadband speed internet connectivity for users.
Wireless
Technology
enables clients to access the Internet & Network over a
shared broadband connection whether working from a traditional office,
relaxing Home Office or away from base on business trips.

WiFi
BROADBAND INTERNET ACCESS ... internet access when away from home or
office
Free
internet access via WiFi is still a new concept in the UK where WiFi
is seen as a 'money maker' rather than an add-on service to draw in
new customers.
Laptop users
choose establishments that offer free WiFi Broadband
internet access. Those that do not, are seeing their prospective customers taking their laptops
and business elsewhere!
With
BT Openzone and BT FON Hotspots springing up everywhere, BT
Broadband customers are offered free internet access via private WiFi
networks from nearby homes & businesses.
All WiFi signals should be protected by a network keycode before allowing you to connect,
but many still do not.
Inadequately protected WiFi networks allow access to the internet for free, which is can lead to a conviction of
dishonestly obtaining an electronic communications service plus
confiscation of your laptop.
BT
OPENZONE is an easy-to-use broadband internet access service
for a Monthly Subscription or Pay-As-You-Use Charge.
Using
WiFi wireless
technology,
you can access the internet - with no download limits - at any
access point in cafés, camp sites, hotels & airports in the UK.
Many
locations include free WiFi
Broadband within their standard charges - so check before you book
& choose one that does!
SKYPE
ZONES is a little piece of software powered by Boingo that gives you
access to Skype through thousands of Skype-friendly hot spots, while
you’re on the move.
Accessing Skype
Zones and enjoying Skype from hotspots is not free, but it is very reasonably priced!
Visit Skype via the icon link (see left) for more information.
MOBILE
INTERNET ACCESS
... email & internet access when mobile
WiFi communication
is just one option, the other is
3G broadband data services provided by mobile phone operators
offering
convenience over speed. WiFi Hotspots should provide faster data transfer speeds, but you will have to go looking
for a WiFi signal.
Mobile phone 3G services
offer wider coverage, but not yet available from all mobile phone
masts. New technological advances are occurring all the time: a
new wireless format promises to more than quadruple download speeds.
OFCOM may also allow
service providers to strengthen their signals to improve coverage.
When travelling, mobile broadband connects your laptop to the Internet using your
built-in WiFi, USB Adapter or slot in PCMCIA card.
Your
Built-in WiFi Interface (USB Dongle or PCMCIA card) uses
power continuously, so switch it off (or remove it) when not in use to conserve your battery.
Using high-capacity 3.5G technology,
HSDPA is a software enhancement to an existing 3G W-CDMA network
infrastructure & allows mobile clients access to the Internet at
broadband speeds up to 3.6Mbps now being installed.
Further improvements could offer up
to 10Mbps broadband
connection speeds over 3G.
When
travelling, leave those larger email messages & attachments on your Internet
Service Provider's Mail Server for when back on broadband. You
can check your Mail Server's Inbox via your ISP's webmail if a
large email is expected.
It takes just a
few minutes to change the settings in your e-mail program -
3G
- 3rd Generation
3G is the
generic
term used for the third generation of mobile communications systems
created to deliver up to 384Kbps connections - using the W-CDMA air
interface, such networks are labelled 3GSM.
Vodaphone Mobile Connect 3G/GPRS Data Card purchased
separately is about the size of a credit
card. It slots into a spare PCMCIA Slot leaving the red end with indicator
lights and aerial protruding.
Where a
3G Signal is not available, connections fall back to EDGE as default
- see below.
EDGE
- Enhanced Data rates for Gsm Evolution
When
you talk on a mobile phone, a continuous connection to a channel is
reserved for you on the GSM network, which means nobody else can use
that channel. With EDGE, you can still have a continuous connection,
but you only use the channel when you're sending or receiving data. So
one data
channel can be shared by three users. So you are only billed for
actual data transferred, not for the time connected.
EDGE is significantly faster than
GSM Data but transfers are slower during peak hours in busy cell
networks or when the signal is weak; and for safety reasons
voice connections take precedence.
Where an EDGE network is not
available, connections will fall back on GPRS as default - see
below.
GPRS
- General Packet Radio Service
A GPRS Data Card offers wireless internet
access on your laptop for online working wherever you want, whenever
you want via local mobile phone mast network. You get an always-on internet
connection which lets you send and receive email, browse the web and
download files at anytime.
With a Data Card (or 3G/GPRS
compatible mobile phone), you can do pretty much do everything you'd do
at your desk.
GSM
- Global System for Mobile communications:
is the wireless technology that underpins most of the world's mobile
phone networks & has created a global mobile phone standard. 14Kbps Data connection speed is now well below 3G,
but it was an improvement on 9.6Kbps Dial-Up.
BLUETOOTH
is a low-power, short-range wireless connectivity that allows devices (phones, printers, keyboards & headphones) to communicate with one
another. While not inherently unsafe, it needs to be properly used to
avoid risks -
Bluetooth users should be aware
of the three main vulnerabilities:
BLUESTUMBLING:
discovering other people's Bluetooth devices within range.
BLUESNARFING:
obtaining information from a 'bluestumbled' device.
