Thinkpads Forum

Hi,

My T30 (4 years old now) has served my well, but is heading for replacement by a new T60 soon (although I would like to wait for the Wide screen ones), but I have a question about the WWAN in the T60's.

I did some research on the WWAN modules in the thinkpads and they all seem to use the Sierrea Wireless PCI Express Mini cards for HSPDA networks:

MC8755 - 2100 MHz HSDPA UMTS frequency band (used in Europe and Asia) - Cingular.
MC8765 - 850/1900 MHz HSDPA UMTS frequency bands (used in North America) - Cingular.
MC5720 - EV-DO Networks (probally only in North America) - Verizon.

These support peak downloads of 1.8 Mbit/s. But checking out the
Sierra Wireless website http://www.sierrawireless.com/product/oemmodules.aspx), I can see that the MC8775 supports all frequencies (used worldwide) as well as the "Turbo-3G" peak download speed of 3.6 Mbit/s, which is starting to be available in a few countries in Europe.

MC8775 - 850/1900/2100 MHz HSDPA UMTS frequency bands (works worldwide).

This module seems to make sense for me living in Europe, but traveling quite a bit, and would like to get rid of the 3G PCMCIA card that I use in my T30.
It seems as long as I know which module (and thus where it will work) is in the machine I can pop whatever SIM card (after getting an unlock code from Lenovo) I want into the machines and use it where that SIM card has coverage and/or roaming.

My questions are:

1) How to determine which WWAN module is in a specific Thinkpad model?
2) Is there or will there be a Thinkpad available with the MC8775 card?


Kind regards,
Nicolai

I have the Verizon module in my T60p and my firm was able to convince Verizon to give us a one year (instead of two) deal. At present, Verizon EVDO seems to have the widest coverage here in the USA.

I just got a Cingular BlackJack phone/Windows Mobile 5.0 PDA which has HSDPA G3. I can use this device as a bluetooth modem; here in Chicago, it gets very fast downloads - possibly faster than the Verizon although I haven't done any tests yet.

Unfortunately, the wireless companies' announcements of their high speed coverage seem to get a wee bit ahead of reality, so it's difficult to know which way to go for North American coverage.

I haven't tried the Cingular device in Europe yet and won't until early 2007. However, the data roaming charges from Cingular will eat you alive. On my return after a three week trip to Australia this summer where I used my Cinglar 8125 to check e-mail (instead of paying hotels $A20 per night for high-speed connections) I was greeted by a $800 Cingular bill - proving that I should have paid the $A20 per night.

I have the T60p with Verizon EVDO. It works well in the US, but there's now a new version out and no simple upgrade path for the built in variety as far as I can see. I'm spending several months in Europe right now and have the Vodaphone UMTS PCMCIA card which is awesome - in London you really can get 2 megabit, shame that in the rest of Europe I only see 384K

Given the choice again I'd skip the built in, you also get to choose networks that way.

Well I am mostly in Europe, and in some European countries (Sweden, Germany and a few others) 3.6 Mbit/s is starting to become available.

I also read somewhere that they managed to get an unlock code from Lenovo to unlock it (an thus use any SIM card they like in it). Roaming is a killer though, but I would try to use a local SIM card to as a large extent as possible!

But I would not go for the built-in one unless it has world-wide frequency support (the 3 HSPDA freqs and 4 GSM). I have 3G UMTS card in T30 now which works fine, bit I would prefer a built-in one (one less thing to carry around...)

PS In Europe the EU comission might put a legislation in-place the hinders the high roaming charges between different EU countries.

I am using a T60 without UMTS-module.

Is it possible to upgrade to UMTS?:

- is the SIM-card-holder part of the PCI-module or placed anywhere else in the Thinkpad?

- are there antennas and/or cables needed in addition to the module? Does anybody know the FRU-numbers for these articles?

- is there only a Vodafone-branded UMTS-module available by IBM als FRU / are unbranded units available by resellers?

Thank you very much for your help.

The SIM card holder is accessible from the underside, after one removes the battery. Not all machines have a SIM card holder. The SIM card holder (FRU #41W1353) can be added to any T60 machine after removing the keyboard. It is a small circuit board with SIM socket and a 2cm cable and connector which attaches to the motherboard.

Antennas:
The primary antenna is installed in the LCD panel casing; the secondary antenna is installed on the top left underside of the keyboard bezel. Use the proper FRU #s based on your screen size and your WWAN service provider, shown here: http://www-307.ibm.com/pc/support/site. ... GR-62741#1
