Just wondering... Can I use a 3G phone connect to the Woosh network? I know nothing about the difference between the types of UTMS, so its just a thought... It would be cool to surf the net with a 3G mobile on the go via the woosh network since its much cheaper than vodafone 3G and Telecom T3G...

No, I don't think you can... and even if you could - I don't think they'd let you.

You cannot...

027 is EVDO

021 is UMTS

Woosh is TD-CDMA


3 totally different network types on 3 totally different Frequencies (like AM, FM and TV won't work on each other.)

TD-WCDMA (Woosh) actually uses the same frequencies as UMTS but uses unpaired frequencies rather than the paired frequencies used by all the other mobile technologies. This meant Woosh were able to get their spectrum at a bargain basement price compared to the other buyers in the 3G auction as they were about the only company who didn't want (or need) paired spectrum.

well be noob here why is there a sim card slot for the IP Wireless branded Woosh modem's? i know its more for smart card verification as MSD use them now in welly. but other than that why is it when i unpack the exe it has vodafone bmp's in there?

Further cracked into all binaries of the UEStatus.exe and dll's and found this to be interesting:

[HKEY_LOCAL_MACHINE\SOFTWARE\IPWireless Inc.\IPWireless Modem Software\SIM Settings]

For legal reasons (as i co manage a top level data security comp.) i wont say how to modify anything further but to finally add;

I'm not quite sure what you are trying to get at with your post but if you think for some reason that the Woosh modem can be used on Vodafone's 3GSM network or vice versa then you really need to learn a bit more about cellular standards. It will not work. Full stop. Period. WCDMA-TDD is a variant of the 3GSM standard and is not compatible.

I suspect the Vodafone BMP's are probably in the install package as Vodafone were a Woosh reseller and at one stage there was speculation that it would also be sold under the Vodafone brand hence having a Vodafone branding on the software. Vodafone did have the option of purchasing part of the company after their initial co-siting deal but they didn't take it up.

What's with resource editing the Woosh software? yes there is a vodafone logo in there and a pile of other operators.

The backend for Woosh and Vodafone is the same - both based on the UMTS 3G standards born out of GSM.

However, the radio tech is vastly different - Vodafone style UMTS (used in NZ, and by all the big global players you had GSM) is Frequency Division Duplex (FDD), where seperate channels are divided by frequency: and Woosh style UMTS is TDD (Time Division Duplex), where seperate channels are divided in time.

Wrong - UMTS is not from GSM it is from CDMA and is also refered to WCDMA. Most of the patents around UMTS are owned by Qualcomm. It is also refered to as IMT-2000.

UMTS uses both FDD and TDD.

Read: http://www.umts-forum.org/servlet/dycon/ztumts/umts/Live/en/umts/3G_Network_gsm

Some of the modulation, signal processing techniques etc. used for the radio may be similar between CDMA and W-CDMA, but the backend etc. is an evolution of GSM. It was the way the backend was designed and standardised for GSM that made it so successful - the radio tech used on the physical layer only affects the data rate, not the operation.


Qualcomm owns the patents for the old CDMA standard (what the older 027 network ran on I think) - not the newer W-CDMA.

Qualcomm own most of the patents for WCDMA and have 130 licensees uncluding Nokia, NEC and Motorola.

I don't think 130 companies would pay Qualcomm money for WCDMA if they didn't have to.

Sure, the Core Network is based on GSM/GPRS however the UTRAN (Radio Access Network)and UE (User Equipment) are both based on CDMA.
