Prioritisation of frequency bands & technologies

What is the overarching priority EE set for all frequencies/technologies across the network? E.g.

1: 2600 MHz LTE

2: 1800 MHz LTE

3: 2100 MHz UMTS

4: 800 MHz LTE

5: 1800 MHz 2G (GPRS/Edge)

 

The above is my 'best guess' based on my own experience.

Re: Prioritisation of frequency bands & technologies

Welcome back to the community @xpz393

 

This is not something I am aware of.

 

I will see what I can find out for you though and get back to you when I have some more information.

 

Thanks.

Thank you for looking into this for me @Leanne_T ; I'll look forward to your update.

No problem at all @xpz393

 

Speak soon 🙂

800MHz should sit above 3G, but only if you're on Pay Monthly.

Re: Prioritisation of frequency bands & technologies

@nikiandemma You'd think so, but there's an area I visit where outdoors the phone flits between 3 bars of 800MHz 4G and one bar of 2100MHz 3G, so it's behaving as though 3G is prioritised above 800MHz 4G even when that 3G signal is weaker. 

 

This is why I'm really keen to hear back from @Leanne_T for definitive confirmation as to how the bands are indeed prioritised.

Re: Prioritisation of frequency bands & technologies

From experience 800Mhz becomes over-crowded quite quickly due to it's perceived prioritisation and will often throw you back onto 3G. Sounds like the area you visit is just outside the edge of 4G1800 and so you get the slightly stronger 3G fall-back instead. I admit it's a frustrating setup and the 'life-saving' 800MHz is so limited in terms of speed and capacity. Will see what info @Leanne_T provides.

Thank you @nikiandemma for providing your experience.

 

I will get back to you both when I have further information 🙂

Re: Prioritisation of frequency bands & technologies

800mhz is above 3G in priority it's just that at the moment for the majority of the country 800mhz is operating on really low power. When the power is turned up people with VoLTE capable devices will pretty much never see 3G/2G again.

Re: Prioritisation of frequency bands & technologies

Seen similar behaviour where 4G800 was available but the iPhone sat on 2 dots of 3G. Had to cover the antenna area for it to latch onto 3 dots of 4G800. The site is at Empingham, Rutland so no chance of any congestion. Speed test gave a reasonable 18Mbps down.

Re: Prioritisation of frequency bands & technologies

Thank you all guys for adding real value to this conversation and for all the continued questions and desire for information.

 

@Leanne_T is off today, but she will get back to people with further information as and when she has it.

 

Thank you all for coming here to community

Re: Prioritisation of frequency bands & technologies

one area I work I can easy get 2 bars 4G800 inside house but do not know why the Iphone SE would choose 1 bar 3G/2G or often NO SERVICE. If EE will prioritise  3G over 4G800 that is shocking

Re: Prioritisation of frequency bands & technologies

Hi @xpz393

 

its definitely this in 800 live areas:

 

7. 2600mhz 4G

6. 1800mhz 4G

4.800mhz 4G

2100mhz 3G

1800mhz 2G

 

in testing areas 800mhz maybe priority level 0

Re: Prioritisation of frequency bands & technologies

Indeed 800mhz is above 3G 2100. 800mhz is for the moment on very low power in the majority of the country.

Re: Prioritisation of frequency bands & technologies

So, we're a 50/50 split with myself and @georgereading experiencing a situation which would suggest that 3G is prioritised above 800MHz 4G, yet @sully1311@toffeebrann understanding that the reverse is true...

 

Let's see what @Leanne_T confirms from EE's tech teams - either way, I suspect further discussion will unfold 🙂

Re: Prioritisation of frequency bands & technologies

Morning @xpz393

 

Just a quick post to let you know we're still looking into this for you!

 

Myself or one of the team will post as soon as we have any info!

 

Cheers.

Re: Prioritisation of frequency bands & technologies

Also do you have a 4g calling phone (does your 4g stay on when in call, what phone do you have) if no then you can't access 4g800 any way until ee changes there stance on 4g800 for 4g calling enabled phones only at the moment

Re: Prioritisation of frequency bands & technologies

Idle reselection parameters are as follows:

B3, B7 (3350, 3179) are all reselection priority 6

B20 is reselection priority 4 (To confirm these, check the Signalling Block SIB5.)

3G (10761, 10786) priority 3

3G (10811) priority 2 (3Gs can be confirmed in Signalling Block SIB6)

2G

I assume the last two  3g's is basic umts and HSDPA/hsdpa-dc ?

 

And I assume Idle is like when data is not actively transferring

as I do tend to notice that my phones refuse to step up to 4g when say streaming live videos as there is not much of a gap (iPhone and. Blackberry don't seem to mind switching when streaming)

Re: Prioritisation of frequency bands & technologies

EE has four 3G carriers in total, which are contiguous. Each contiguous pair can be used for DC-HSPA. Masts typically have 2-4 carriers deployed, mine has three. Fundamentally, 3G is below 800 priority wise.

 

Idle is when the phone is idle yes.

 

You can't reselect from 3G to 4G when phone is data active. Phone has to be in an (almost) completely idle state to reselect. Some devices idle much faster hence can move up to 4G despite being apparently active data.
