LTE Advanced/Carrier Aggregation

Does Fido have carrier aggregation, and if so, in which configurations?  I have an M4 Aqua I bought from Fido, and I have never seen it on anything but AWS (1700/2100 aka Band 4).  I know it also supports LTE bands 7 (2600mhz) and also 12/17 (700mhz).  Does Fido support LTE-Advanced like it's parent company?  Also, I am in Ottawa, which on rogers coverage does not have LTE-Advanced.  Odd, since we were the launch market for Rogers LTE in 2011.  Supposedly, Rogers has aggressive LTE-Advanced rollout plans, but we are getting close to the end of the year, I was expecting to see it here by now.  

 

Also, if anyone knows of an app that allows me to switch LTE bands on a locked, unmodded M4 Aqua running 5.0 lollipop, that would also be greatly appreciated Smiley

Hello,

 

  Just to clarify, a category 4 LTE device does not necessarily mean the device is LTE-A capable. The LTE categories only define maximum transmission speeds. For example, a category 4 device/network is capable of maximum download of 150 Mbits and upload of 50 Mbits. 

 

  While a category 4 device may indeed be LTE-A capable, those capabilities are dependent on hardware. For example, the following screen capture of 412 and 415 processors is taken from the comparison of Qualcomm Snapdragon processors.

Snapdragon 400.jpg
   If you note, both integrated modems are category 4 but only the modem in the Snapdragon 412 is capable of LTE-A.

 

  The processor in the M4 is the Snapdragon 615:

Snapdragon 615.jpg

 

    Unfortunately, the Snapdragon 615 does not appear to be capable of LTE-A.

 

 

  With regards to band selection, the phone would select the best band given the circumstances ie signal strength, channel bandwidth, etc.

 

  Bandwidths are scalable (1.4, 3, 5, 10, 15, 20 MHz), designed to help operators more easily migrate from narrowband technologies (e.g., GSM and CDMA2000) to LTE while also recognizing that wider bandwidth deployments of LTE would be required to achieve the target peak data rates (taken from here).

 

  Assuming the Fido bandwidths you mentioned are correct, then the phone would connect at 2x10MHz on band 4 and 2x5MHz on band 7. I suspect under different circumstances ie poor band 4 signal strength combined with good band 7 or 17 signal strength, the phone will use another band.

 

Hope this helps Smiley

Hello,

 

  It looks like Rogers' LTE-A will be aggregating both bands 7 and 17 with band 4.

Cawtau,  Thank you for pointing that out from qualcomm's site.  I can't believe I didn't notice that before purchasing the device ;).

Re: LTE Advanced/Carrier Aggregation

Hey! I also was wondering the same thing, and did have 2 questions.

I am thinking of getting an unlocked phone (Samsung Galaxy S6 International  Version) which is compatible with LTE bands of:

1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 17(700), 18(800), 19(800), 20(800), 26(850)

And I wanted to ask, is this phone comatible with Fido's LTE-Advanced network (carrier aggretion) and is it VoLTE compatible? Again it is an unlocked phone.

Thanks,

Regards.

*UPDATE*

Sorry forgot to add my location, I am near Couborg, Ontario, and hour East of Toronto. The ROGERS towers near my area provide signals at a Frequency of 850Mhz and 1900Mhz.

@Sami123! We're looking to obtain more info on this. We'll update this thread shortly. Smiley

Hello Sami123,

 

 Welcome to the forums!

 

  First, that phone would have all of the bands/frequencies for LTE. You can verify the compatible bands here.

 

  With regards to carrier aggregation and voLTE, I believe @FidoMaria is looking into it for you.

 

  With regards to your last statement, are there additional towers with different bands/frequencies in your areaÉ If those are the only bands/frequencies in the area, you are not likely to get LTE. There are no LTE bands/frequencies at those towers you listed.

 

  Hope this helps Smiley

 

Cheers

Re: LTE Advanced/Carrier Aggregation

Oh I see, I checked an online database, that may be inaccurate. ertyu.org. I do get LTE there, as I have another phone that does recieve LTE.

Hello,

 

  I tend to use that site as well. It is entirely possible that some of the tower information needs to be updated. However, does your phone actually show LTE or does it show 4G? If it's the latter, it's possible that the connection is H+ rather than LTE, which would correspond to the bands/frequencies shown in the area.

 

Cheers

Re: LTE Advanced/Carrier Aggregation

It shows LTE (Long term evolution or Real 4G LTE) not HSPA+ (3G/H/ Fake 4G). My area is also covered by LTE according to Fido's coverage map.

I have just bought the S6 Smiley and just wanted to know will an unlocked S6 be compatible with LTE-ADVANCED (CAT 6) and/or VoLTE (HD Voice).  Also I am out of the country at the moment and can't access Fido just yet, until I come back to Canada. @FidoMaria@Cawtau

 

Thanks! Smiley

Re: LTE Advanced/Carrier Aggregation

Hi there Sami123

 

We only offer the LTE network at the moment. Although there's no mention of LTE-A on Fido.ca today, we're still looking into it, to get more information 😃 I'd simply suggest to stay tuned here for updates. 

 

To obtain the VoLTE (HD Voice) service, you must have a Fido phone (no exceptions) as the service is not available to non-Fido devices. 

 

I hope this helped!
