Thanks to Compaq EMEA, several weeks ago I got a carrier test sample of the
Compaq GSM/GPRS Wireless Pack. This means that it is fully functional and works
as the commercial versions will works later. However, some features aren't
available in the sample version or other features are available, which will not
be included later.
The Compaq iPAQ Wireless Pack for GSM/GPRS Networks broadens the
functionality of Compaq iPAQ H3600, H3700 and H3800 Pocket PCs to include data
and voice capabilities. The Wireless Pack combines Global System for Mobile
Communications (GSM) and General Packet Radio Service (GPRS) technologies to
allow users to access the Internet and send and receive email and Short Message
Service (SMS) messages, in addition to making wireless phone calls. The Wireless
Pack essentially converts the pocket PC to a mobile phone and wireless data
device that can be easily and conveniently taken anywhere also because it
supports GSM 900, 1800 and 1900 MHz.
I'm using the Wireless Pack for 3 weeks now. But first some hard facts:
The Compaq iPAQ Wireless Pack enables impressive call and data functionality
with a rechargeable 1000mAH integrated battery and Tri-band functionality. Users
receive up to 180 hours of standby call time and four hours of talk time on a
single charge. The Wireless Pack is a Multi-slot Class 10 data device that
provides extensive, reliable, wireless data communication that is "always on" in
GPRS-covered* areas and has packet-switched data at speeds of up to 144 Kbps in
GPRS-covered areas. The GSM/GPRS network requires a SIM card to assure user
authentication and enable private data transfers.

The whole Wireless Pack is pre-configured, you don't need to install any
additional drivers on your Pocket PC. That means that you can just slide the
pack over your iPAQ and everything is going by itself. How is this possible?
It's because the pack is recognized by the iPAQ and the Wireless Pack has an
additional Flash ROM. That means, that all required drivers and applications
comes with the Wireless Pack and runs from there from the first time.

Depending on your regional settings, you are using on the iPAQ, the Wireless
Pack provides you the proper language based on this settings. By default it
includes English, German, French, Spanish and Italian. This is interesting as it
means that you can run a German Wireless Pack user interface on an English iPAQ.
After you've connected the pack you have to enter the SIM card PIN as you know
it form your GSM mobile phone.

Now you are in the telephone application. Looks, feels and smells like a mobile
phone. The display shows you the current network operator and on the top bar you
see on the left side the signal strength and two batteries. the left one with
the "i" is the battery status of your iPAQ, the right one is the battery status
of your Wireless Pack. The green LED means that you are successful connected to
the GSM network and it blinks - for example - if you setup a voice call. The "G"

The phone GUI is skin-able and Compaq delivers various skins for the Wireless
Pack. Currently I didn't see how to customize this but this should also be

Under "Voice Settings" you are able to set the Ringer sound and volume. The
kind of call indication (the Wireless Jacket can indicates rings by vibration
also) but you can also select the skin here or change the PIN. A little bit
irritating is, that the frequency selection (the Wireless Pack isn't an
automatic triple band device but you have to switch between 900/1800 MHz and
900/1900 MHz by yourself) is part of the voice settings and not of the network
On the "Network Settings" menu you can select the operator to use, setup the

Okay, that's how the Jacket works in conjunction with its software but how
does it works in the real life, specially for voice calls? Well, the basic
functionality, setting up a voice call can be done without an additional stylus.
Just tap the number on the large keys with your thumb and press the green key.
To finish a call you have to press the red key.

One of the most interesting functionalities is that the Wireless Pack also
receive phone calls, even if the iPAQ is switched off. In that case, the
Wireless Pack wakes up the iPAQ and launch's the voice application to indicates
who is calling. This is fantastic and makes the Wireless Pack unique since other
solutions like the Nokia Phone Card requires a running iPAQ to receive voice
However, Compaq isn't using the Microsoft Wireless Phone Edition of Pocket PC
2002 but implemented the whole interface by itself. Therefore it completely
differentiates from what we have seen on Wireless Pocket PCs like the O2 xda.
Because of this, Compaq also has to use its own SMS solution. Microsoft made
some huge changes in the Inbox application, that it isn't possible for external
companies to use the Inbox for SMS. Therefore Compaq built it's own SMS
application which looks and works like the Inbox anyway.

Even if the Wireless Pack supports voice calls, the strength is - for sure -
it's data capabilities. It is today's fastest available GPRS device and surfing
with the Wireless Pack makes real fun. Even if it doesn't support HSCSD, it
supports everything the road warrior needs today to stay in contact. Setting up
a GPRS account is easy.
In the Connections menu you got an additional icon for GPRS/GSM. Here you
have to setup your wireless data connection, not a in the Connections menu as
used to use for the Pocket PC 2002. On the GPRS - GSM Connections menu select if
you want to setup a GSM CSD or GPRS account.

menu, the GPRS/GSM icon

In the following dialogs enter all required GPRS settings, from the APN to
the IP and DNS server. That's it. More tricky is that you have also to change
the Connections Setting. Beside the Internet Settings, you will also find there
the Compaq Wireless Pack. To make a data call through the Wireless Pack, this
have to be selected.

While the Wireless Edition of Pocket PC 2002 still doesn't provides any
information about the data sent and received or even the throughput as you know
it from Windows on your desktop PC, Compaq added this functionality to the

The data speed is enormously, it's the fasted GPRS device I've used so far.
Surfing the Web and getting E-Mails isn't a problem with the Wireless Pack.
However, because it use mostly one channel for up-streaming only, sending
E-Mails takes as long (sometimes even longer) as using a CSD connection through
GPRS. What I really like is that the GPRS module/stack is working very stable.
I've never seen this phenomenon that I have to reboot the jacket if I disconnect
from GPRS and want to reconnect later again. This is a typical bug on today's
mobile phone but not on the Wireless Pack. Even if you interrupt the connection
by switching of the device you can re-logon to the GPRS network next time
without any problems. That's great and mature. That's how I expect to work a
Size, Weight and Stand-by
The Wireless Pack is a little bit thicker than a CF card jacket but thinner
than the PC card jacket. With its 166 g it adds the double of the weight of a
modern GSM phone to the iPAQ (for example the Ericsson T68 weights 68 g only)
but on the other side Compaq added a 1000mAH battery to the jacket. This is one
reason why there are no additional expansion slots (everything which isn't the
GPRS module is the battery) which lets the Wireless Jacket itself runs up to 180
hours of stand-by time and four hours of talk time. The stand-by time isn't
marketing nonsense, it's real. At least in my tests the jacket runs up to 3 days
without any recharges including additional usage (voice calls and GPRS
connections). My iPAQ required a power plug every day, while the jacket worked
fine on the next day, even if I forgot to recharge it in the night.

From the handling, the Wireless Pack/iPAQ combination fits perfectly into the
hand. However, it's for sure a little bit thick and heavy to carry it in the
pocket of a shirt. What I really miss is a case; but as Compaq told me, there
will be an option available later this year which allows you to carry the
Wireless Pack on your belt.
The Wireless Pack isn't a replacement of a mobile phone, it's
complementary as the whole Wireless Pocket PC 2002s are complementary, doesn't
matter if it is a O2 xda or a HP WDA. It is made for road warriors and professionals who needs Internet access. If you are looking for a new device instead using your mobile phone, you can stop reading here.
If you are looking for a serious solution to access the Net to use Web, E-Mail or even the Intranet via VPN, the Wireless Pack could be your solution. I like the whole data functionalities: it's easy to configure, fast
and works very stable. Even voice calls are no problem. However, the voice interface has some weaknesses as I also saw before on the xda. It's not made to interact with the SIM card in the traditional way. So it's not possible to dial
numbers from the SIM and as I'm more the traditional mobile phone user, my SIM card contacts differentiates from my Outlook contacts. That's a real weakness for me. However, the Wireless Pack allows you to make phone calls even without a headset as the loudspeaker and the microphone are included. That's important for
me as I used to loose/forget my headsets. Unfortunately a Bluetooth headset will never works with the Wireless Pack. Even not if you are using the iPAQ H3870 as the voice interface isn't connected to the iPAQ by itself.
A pro is the "wake up" functionality. You can switch off your iPAQ to save battery but it wakes up if you get a mobile call. However, this needs some time and you shouldn't use a redirection to the voice box less than 15 seconds. Otherwise you will be often to late to get the call.
The data integration is - as said before - perfect. It takes only some minutes to configure the GPRS and if you use GPRS it's really fast and stable; which is the most important for me.
I can recommend the Wireless Pack for everybody how needs professional access to the Net. Non professionals, or user who want to access the E-Mail from time to time only should better think about a Pocket PC/Mobile
Phone connection; but again the philosophy behind all Wireless Pocket PCs (doesn't matter if integrated or like the Wireless Pack) is data centric with voice support, while the new Smartphone 2002 is voice centric with data support. Everybody has to make the decision for himself and I will still use it in future
regular, even if I have Bluetooth enabled Pocket PCs and Bluetooth enabled mobile phones.
