Looked at the coverage map and there is DC 3G in places you wouldn't expect ... Inlcudes my house!

Do i need a 4g sim uo get DC 3G?

My speeds are certainly not DC here ...

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

 



 

If you are posting regarding DSL speeds please check that

 



 

- you have reset your modem and router

 


 

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

 

- you are not being throttled by your ISP due to going over the monthly cap

 


 

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

 


 

- you read this topic and follow the instructions there.

 



 

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

 



 

- Your ISP and plan

 


 

- Type of connection (ADSL, ADSL2, VDSL)

 


 

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

 


 

- Your general location (or street)

 


 

- If you are rural or urban

 


 

- If you know your connection is to an exchange, cabinet or conklin

 


 

- If your connection is to a ULL or wholesale service

 


 

- If you have done an isolation test as per the link above

 



 

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

 



 

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

 



 

I recommend you read these two blog posts:

 



 

- Is your premises phone wiring impacting your broadband performance? (very technical)

 


 

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

Just get a master filter and stick your SIM in there ;-)

No new SIM required for Dual carrier access, DC is just the normal 3G network

Dual carrier speed will depend on the load of the serving cell

I am beginning to think my Telstra Australia firmware is doing something weird on the NZ networks ... my speeds have not changed ... what DC!

Have you rooted the handset and loaded different software on it?

I have rooted it but no changes to anything else. I have the TNZ modem loaded.

You'd have to test at 3-4am if you want to know whether you're getting dual carrier speeds imo. The network is generally too loaded for you to see speeds that you couldn't get with single carrier HSPA+ during normal hours. I haven't seen a speedtest over 10 megabit in ages.

It should just work - providing your android device supports HSPA-DC - I haven't come across any devices that can selectively disable Cat24.

Like all things mobile/cellular performance can vary du to several factors, including coverage, load, and device capability...




My comments and remarks are not necessarily of my employer.

ok thanks. can't beat physics I guess - low frequency long wavelength = less capacity compared to the friends in Red.

BUT - it means that I get superior signal in my concrete block where I work

however I still think that these phones are a minefield to work with - there are so many settings buried inside the code of firmware - unfortunately the galaxy s4 I have I can't get into the hidden menus to look at things like fast dormancy, H+/H/3G toggling etc

heck the other night I read about that guy's Vodafone note 3 that can't latch onto telecom's 4G! insanity!

Capacity on a mobile network is measured in spectrum bandwidth Mhz not the band you are operating on,

Coverage foot print comes down the frequency used

Where are you based??? I can see what sort of DC it is, be it 850Mhz or 2100 DC.. as they are different.

But DC should work no matter what as long as your device supports it, and it's just up to cell congestion as John has already said :)

The Service Mode will tell you if you're connected to DC or not. Dial *#0011# & look for "DC_HSPA+ 1".

gajan:

I have!

Some very odd settings in that thing, being able to manually specify a preferred UARFCN was new to me.
