How to access T-World from your iPhone

, posted: 9-Sep-2009 15:32

Here are some simple instructions on how to access T-World on your XT connected iPhone.

Remember you can only access T-World if you are connected to the XT Network

Using Safari browse to http://pdaportal.telecom.co.nz



This should present you with a log in screen


 
Select “Send New Password”

This will open up a new “page” for you to get a password sent to your mobile as a text message



 Once you’ve filled in the details and selected "Get Mobile Password", you’ll be sent a text message with a temporary password.




 

Return to the original Safari Page and enter your phone number and the temporary password.



You will now be redirected to the T-World front page



 






















Now you can select “Your Telecom” to view your account details.


 
You can set a permanent password by using the link at the bottom of the page "Manage Password"



XT Network SIM PIN's & PUKs

, posted: 8-Jul-2009 13:57


The XT Network SIM cards have two levels of access each with their own Personal Identification Number (PIN). When you get these PIN's wrong too many times you then require to use the PIN Unlock Key (PUK) to reset the SIM.

If you get your PIN1 wrong 3 times you then need PUK1 to unlock the SIM. If you get PUK1 wrong 10 times then your SIM becomes "PUKed" and needs to be replaced. These retries are the same for PIN2 and PUK2.

PIN2 is primarily used to access and control functions such as Fixed Dialling numbers.

PIN1 Default - 1234
PIN2 Default - 1234
PUK1 - printed on the SIM card that your SIM was attached to. Also available by calling Telecom.
PUK2 - Available by calling Telecom customer care.

Users are able to change both PIN1 & PIN2. PUK's are unique to a SIM card but cannot be changed.

TelecomNZ New WCDMA 850 Network

, posted: 3-Apr-2009 13:57

Here are some facts about the new Telecom WCMDA network.

The new network will have WCDMA850 technology across the whole of it's coverage. This coverage is comparible with the existing CDMA network which covers 97% of the New Zealand population. Some metro areas will have both WCDMA850 and WCDMA2100. WCDMA850 will be available everywhere.

Telecom have no plans to SIM lock phones they sell. SIM Lock means that only a particular carriers SIM card will work in a handset. Telecom will not be doing this.

Some Vodafone handsets will work on the Telecom WCDMA network as long as the Vodafone handset has WCDMA850 as one of the frequency options. A Telecom SIM is required to connect to the Telecom WCDMA network. The user will need to change some handset settings to enable the various data services to work on a non Telecom sourced device. Some media services may not be available due to handset limitations.

WorldMode SIM will not be able to access the Telecom WCDMA network. WorldMode SIMs are not able to access New Zealand networks.

WorldMode devices are not compatible with the Telecom WCDMA 850 network, this is a device limitaiton. None of the Telecom WorldMode handsets are compatible with the new Telecom WCDMA 850 network. This includes the BlackBerry8830, Samsung351, Samsungi325 etc. None of these handsts will work on the new network.

The commercial agreement between TelecomNZ and TelstraClear does not enable TelstraClear to resell WCDMA connections. TelstraClear customers are still able to port their number to Telecom, becomes a Telecom customer and have access to the Telecom WCDMA network.



UMTS WCDMA HSPA HSDPA

, posted: 3-Apr-2009 13:45

Universal Mobile Telecommunications System (UMTS) is one of the third-generation (3G) cell phone technologies. The most common form of UMTS uses Wideband Code Division Multiple Access (WCDMA) as the underlying air interface.

High Speed Packet Access (HSPA) is a collection of mobile telephony protocol that extend and improve the performance of existing UMTS protocols. Three standards, HSDPA, HSUPA and HSPA+ have been established.

High Speed Downlink Packet Access (HSDPA) deployments support peak downlink speeds of 1.2, 1.8, 3.6, 7.2 and 14.4 Mbps. Each data speed is defined as a Category within HSDPA.

High Speed Uplink Packet Access (HSUPA) deployment support peak uplink speeds up to 5.76 Mbps. Also uses Categories to describe the various evolutions within HSUPA
 
HSPA+ (also known as: HSPA Evolution & Evolved HSPA) provides data rates up to 42 Mbps on the downlink and 22 Mbps on the uplink. Most common mechanism for increasing data rates is MIMO, a smart antenna technology.

It is worth noting that a number of 3G devices are WCDMA Rel99. This means that either their Uplink or both Uplink and Downlink is constrained to either 384kbps or even worse 128kbps.



High Frequencies vs Low Frequencies

, posted: 3-Apr-2009 13:42

Every wireless technology uses one or more frequencies to send it's signals. How high or low this frequency is will affect how far the signal will travel.

Some rules of thumb;
Higher the frequency the lower the coverage
        more power required to cover same distance
Lower the frequency the better in-building coverage
        less likely to be reflected by building material

This is why companies such as TelecomNZ and VodafoneNZ prefer to deploy their nationwide 3G networks at 850 and 900MHz, respectively, rather than 2100MHz. 2100Mhz is primarily used in Urban/high customer density areas due to the smaller cell coverage area required.

Firstly, I am a engineer. I am not from marketing, sales or public relations. Feel free to correct me if I have got anything technically incorrect.
This blog is a place for me to put technical stuff about mobile networks that I feel may be of interest.



Favorite Question from 3rd form (year8) Science Test:
If it takes three days for a bald headed red herring to swim through a barrel of tar then how long is a piece of string?
