[Q] cellphone and cell tower with either 3g or 4g - Networking

1. is all cellphone with lte cat3 (100 mbps dl, 50 mbps ul) will also support dc-hsdpa?
2. is all cellphone with lte cat3 (50 mbps dl, 25 mbps ul) will also support dc-hsdpa?
3. is all cell tower with lte cat3 (either with 100 mbps dl, 50 mbps ul or 50 mbps dl, 25 mbps ul) will also support dc-hsdpa?
4. my lovely isp will upgrade cell tower from hspa+ [21 mbps dl, 5,76 mbps ul (2100mhz)] to lte cat3 [either with 100 mbps dl, 50 mbps ul or 50 mbps dl, 25 mbps ul (1800mhz)]. will nokia lumia 900 rm-823 can support either lte or dc-hsdpa?

If it supports the LTE band, it will get LTE. If the phone supports DC-HSPA+, it will get DC-HSPA+ if the carrier puts it out. You don't always get DC-HSPA+ just because you upgrade an HSPA+ tower to LTE. But you will likely see better HSPA+ speeds because of the upgraded backhaul.

Is HSDPA the same as HSPA+ under network?

I went to the T mobile store and showed them under about phone > network it shows HSDPA. He said this is normal and it its really HSPA+. Does everyone else have this or is it just me?

http://en.wikipedia.org/wiki/High-Speed_Downlink_Packet_Access
High-Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, also dubbed 3.5G, 3G+ or turbo 3G, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity. Current HSDPA deployments support down-link speeds of 1.8, 3.6, 7.2 and 14.0 Megabits/s. Further speed increases are available with HSPA+, which provides speeds of up to 42 Mbit/s downlink and 84 Mbit/s with Release 9 of the 3GPP standards.[1]
Yea I know that Im asking if anyone has an actual HSPA+ under network that shows up because everyone I've seen around my way has HSDPA. The rep said even though it says that you get HSPA+ speeds.

Mine shows UMTS, but im running cm7.
Scratch that, just got 4g. Says HSDPA.

[Q] The TmoUS hd2 having hsdpa support.

Does anyone know why the hd2 has hsdpa support (hspa+ downloads) before T-Mobile's hspa 4g campaign? It can be considered as half of a 4g device since it only supports 4g downloads but not 4g uploads.
Sent from my HD2 using XDA App
the htc hd2 supports up to 7.2Mbps. But the real 4G t-mobile is coming out is 40+
HSDPA and HSPA+ are 2 different things.
TmoUS HD2 does support HSDPA (when you see the H in the taskbar) but does not support HSPA+
HSDPA (High-Speed Downlink Packet Access) is actually more like 3G+ since I do get insane download speeds on it, and it has the actual capacity to get 14.4 MBPS down (although I don't know anyone who gets that)
HSPA+ (Evolved High-Speed Packet Access) can get up to 42 MBPS down and our phones do not support this.

HSPA+

Hello,
The Xoom has a Qualcomm MDM6600™:
- HSPA+ with data rates of up to 14.4 Mbit/s
- CDMA2000® 1xEV-DO Rev. A/Rev. B support
Is there a way to activate the HSPA+ ? because it is compatible with european networks.
Moved to general.

Philly Tmobile Hspa+

whats the Philly area hspa+ number
HSPA+ 42. Your phone's settings will list it as HSPA+: 15.
Parts of Philly have HSPA+ 42 on the 1900Mhz spectrum, as well. This generally means it should be good there.
thanks but I seem to get better speeds when it says hspa+ 10

Enable 1700 band on 910c?

Is there anyway to enable 1700 AWS /LTE on the 910C using QPST?
I know a few phones have benefited from a QPST modification in the past.
I'm interested in the Exynos Note 4 and would like to use with tmobile however I wonder if there's a way to enable all of the tmobile bands to work to ensure 100% network phone & data coverage compatibility.
It seems the only issue tmobile has is the missing 1700 band for 3G aws, 4G aws & LTE.
Is there a way to enable the 1700 band on the 910C using QPST?
According to Tmobile....

Voice over LTE (VoLTE)
VoLTE (Voice over LTE) allows you to place and receive calls on our LTE data network. Phone calls are connected with a clear and rich experience. You never know when you might need to check Facebook while talking to your mom and sharing your Mobile Hotspot with your friends. All of this, on our amazingly fast 4G LTE network. Here's some of the highlights:
Switch between 4G VoLTE and Wi-Fi without dropping a call!
Enjoy crystal-clear calls with our new HD Voice service.
Browse the web with speed while on a call.
Placing a call connects twice as fast.
4G LTE
T-Mobile's advanced 4G LTE network is smoking fast! With incredible speed, you can do more using our nationwide 4G LTE network. 4G LTE delivers up to 50% faster speeds then 3G. If you're in an area served by 4G LTE, you can expect blazing fast speeds because of our expanded capacity. Check out our coverage map to see all the places we have 4G LTE.*
Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz)
4G (HSPA+)
With 4G, theoretical maximum download speeds range from 21 Mbps up to 42 Mbps. You can take advantage of incredibly fast download speeds, and even use voice and data services at the same time.
Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)
3G (HSPA)
With 3G, theoretical maximum download of 14 Mbps. With 3G, you can use voice and data services simultaneously.
Frequencies: Band 4 (1700/2100 MHz)
2G (GSM, GPRS, and EDGE)
EDGE, our enhanced 2G service, delivers a theoretical maximum download speed of 236 kbps. GPRS, our 2G service, delivers a theoretical maximum download speed of 114 kbps. Typical speeds are between 35 kbps and 45 kbps. Keep in mind, voice and data services cannot work simultaneously when on GPRS or EDGE.**
Frequencies: Band 2 (1900 MHz)
Requirements
It's important to use a device capable of the network type you desire, and you should be in a location that has cellular network coverage. Check out our coverage map to see what areas we service, and check out Phones & Devices for device specifications.
Data speeds vary depending on its operating system, processor, battery life, running applications, peak theoretical speeds, and distance from the cell site. USB laptop sticks almost always offer higher speeds than smartphones, because they use the power of a laptop with larger batteries, processors, and other technologies. Also, downloading information is faster than uploading. There is no way to predict an exact speed with so many factors affecting your experience.

(Bands 1, 2, 3, 4, 5, 7, 8, 17, 20) - N910F, N910C
And according to the providers' link given by B.Diddy, the major US LTE bands are the following:
Verizon:
- Band 4 (1700/2100 MHz)
- Band 5 (850 MHz)
- Band 13 (700 MHz)
Sprint:
- Band 25 (1900 MHz)
- Band 26 (800 MHz)
AT&T:
- Band 2 (1900 MHz)
- Band 4 (1700/2100 MHz)
- Band 5 (850 MHz)
- Band 12&17 (700 MHz)

I have the same situation. Have you fix it for your 910C? What is QPST and what should I do? Thanks in advance.
