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:

Installation

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.

Center and the added

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.

Entering the PIN Verifying the PIN

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" above the signal strength indicates if a GPRS network is available and accessible.

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 possible.
The Tools menu gives you the most options you already know from a GSM mobile phone.

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 settings.

On the "Network Settings" menu you can select the operator to use, setup the call barring and forwarding.

Voice Calls

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.

Setup a voice call Receiving a voice call A missed call

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 calls.

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.

Data Calls

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.

New on the Connections
menu, the GPRS/GSM icon
Add there a new GSM-CSD
or GPRS connection

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 wireless pack.

The built-in data counter 26.7 Kbps is even slow
for the Wireless Pack

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 GPRS device!

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 top: Wireless, PC card, CF card Jacket

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.

Final Conclusion

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.

Cheers ~ Arne

It is an impressive expansion sleeve. But the fact that they left out fax support is rather disappointing for some people. It would truly complete the notion of a wireless and mobile office for businessman who are always on the move.

It would be truly great then!

Posted by Arne Hess on 07.03.02 - 00:00:00

@CH Teo: As I said, the final software CD isn't included in this hardware sample. So today there is also no MMS or additional WAP client packed to the jacket. However, for sure you can use the Wireless Pack for faxing, if you take an additional software like Truefax from KSE. This should works fine but you are right - I should give it a test too!

Posted by Andreas on 07.03.02 - 00:00:00

Arne,

So, does the wireless pack wakes-up on incoming SMS? Also when you put the combine unit into its cradle, does it also charge the battery of the wireless pack?

Thanks

It does faxes, but can I dial into my company's dialup system and connect to the company's intranet?

Posted by Georg Hülble-Königsberger on 07.03.02 - 00:00:00

@Anonymous: Which Software did you use for that? Is it posible to send and receive faxes? Is there a need to keep the iPAQ &quot;on&quot; in receive mode, or will it be wake up, when a fax call is incomming?

Posted by Adamz on 07.03.02 - 00:00:00

Woo Hoo!!  That's worth a donation.  smile 
Can you archive SMS messages and Call logs onto your desktop PC somehow? 
I think I may have to cut a hole in the Compaq expandable case for the antennae.

Posted by Arne Hess on 07.03.02 - 00:00:00

@Adamz: Thanks. Glad that you like it. :-) Do you mean a functionality like the Running Voice Logs which works with Outlook? No, this isn't available today but would be a nice feature anyhow.
But - and that's the most positive - the Pack is flashable and I updated the software several times. So this shouldn't be a big deal for Compaq.
Personally I think the interface isn’t the feature richest/best one available today and I would like to see that other companies like Running Voice or V2R could offer – in cooperation with Compaq? – special interfaces which are flashable too. This means for the customer not to install a second GUI beside the original one.

Hi Arne,

thanx for an great review! smile  I am still waiting for my GPRS Jacket...it has been delayed again til 13. march...I'll believe it when I see it! wink

ONE QUESTION THOUGH;
If I listen to music on my headphones (connected to IPAQ, using Media Player...since I guess the headset hole in the jacket itself can not be used for listening to music played on the IPAQ!?), will I get some &quot;audible&quot; signal in the headphones when there's an incomming call!?

...or must I use vibrate function (or not listen to so loud music;) and hope I notice it.

Heay I use my IPAQ a LOT for listening to music, OK! smile

Sounds great!!!  But how much does it cost?

Posted by Jules on 07.03.02 - 00:00:00

Here's an odd question - Do calls come in over the speaker and microphone built into the iPAQ or through a wired headset? I own (and love) my 3670, but that would mean I'd have to turn the unit upside down to speak, woudln't it? Or is there an integrated speaker and mic on the wireless unit itself?

Posted by Arne Hess on 07.03.02 - 00:00:00

@Andreas: No, the Wireless Pack doesn't wakes up in my version if it gets a
SMS. However, I got information from Compaq that the wake up functionality isn't
final on my sample
@Ronny: Yes, you get the call signal through the headphones, so you don't
miss a call because of this!
@Griffin: Expansys (http://www.expansys.com)
has it for 813,98 € /607.75 US$ and they got a limited amount today - it's in
stock there!
@Jules: Check my earlier report about the jacket
here. It has
an additional loudspeaker and microphone.

Posted by Adamz on 07.03.02 - 00:00:00

@Arne  Yeah Outlook integration for the call logs and SMS messages would be nice but I guess that's not gonna happen.  Can you archive them just as text files by copying them out of some folder though?  I guess that would be sufficient. 
And is there another Tab on that Voice options control panel for assigning hardware buttons to phone commands such as an Answer/End toggle button? 
Also, it looks like in your screen shots that the Caller ID is functioning as only showing the caller's phone number.  Can it associate that number with a contact's number in the contact database and then display that contact's name as the caller instead of only the caller's number? 
I like how it's wedge shaped and thinner than the PC Card sleeve. 
How does one-touch dialing from the contacts list work on this?

The fax software Arne mentions is TrueFax at http://www.ksesoftware.com/default.html. It doesn't appear to work with my Ubinetics card (and PC Card Jacket) which I'm using as a phone on my iPAQ with Running Voice software. All this works OK with a few niggles, one of them being the fax doesn't work. TrueFax supports class 1 fax most &quot;mobile&quot; type cards seem to support only Class 2/3. I have contacted TrueFax to see if they will support this feature - however I don't know if the Compaq GSM/GRPS Jacket will support any kind of fax ? Over to you Arne. Also has anybody looked at the GISMO from Brave New World ? (http://www.gismoclub.com) GSM/GRPS Jacket with 802.11b Wireless built in. I'm with Arne in that the auto wake up feature is cool, as is the ability to use it without the handsfree stuff. Me i'd like Wireless, as per the GISMO, and perhaps a compact flash slot for all those people who don't have the latest iPAQ. It is all very well having these jackets but you can only use one at a time - if that means turing off my phone - then it's not good.  In some situations it's OK, i.e. using a FlyJacket in a presention - would probably mean turning your phone off anyway - but to play music - say in a car - means I have to lose the phone. The GISMO would get me one step closer - as I can use it with our Wireless LAN...a GISMO with a Compact Flash socket with the same kind of features as the Compaq Jacket would be great. I'm also with Arne on the interface - the Running Voice people seem to have got it pretty much perfect.

I addition to my previous post I have to ask the question - why oh why black ! - We've all seen the Silver Slider and how cool it looks in silver - why not the jackets ??? At least the GSIMO has the same sort of wrap round sides as the slider - but still boring black !

Does anybody know of anyone in the UK who does a good job of adding extra memory to the iPAQ's ? I've seen stuff from the USA, but the freight is expensive and I couldn't bear to be without my iPAQ that long. (Actually I'm not sure I could function without it at all !)

Russ

Posted by Anonymous on 08.03.02 - 00:00:00

@ Russell. There is/was a company offering the service in Europe... though I've forgotten the name (useful eh!). I remember seeing the link on www.pocketpcpassion.com   . If you can't find it, the webmaster (Dale Coffing) may be able to help you. Alternatively, visit www.tekguru.co.uk and ask him. I find this is the best UK based site. Hope that helps. (PS: may be cheaper to wait for the nex generation processors and buy an iPaq H3870 with SD slot)
