I am looking at buying a Huawei E398 modem that supports LTE in the 800 / 1800/ 2600 MHz bands.

I want to get this modem because I believe that it will work on my 3G router, whereas I am unsure about the other modems on the market.

According to my understanding of the frequencies involved this will work on Vodacom, MTN and 8ta, but not on Cell C, as I understand that Cell C will be using 2100 MHz.

Any views on this ?
 
@Jola:

I did a similar search this morning.

Although you would be able to connect at 2100MHz, you'll not be able to get LTE at this Freq, only 3.5G.

The Huawei E392 (E392u-21) device do however feature this freq. at LTE speeds, but not advertised through any of the service providers at this time.

We'll have to wait and see what comes our way...
 
By example 8ta trial is @2.3GHz. We don't know what will be final frequency, it could be 2.4GHz. And I am pretty sure it won't be 800/900 nor 2100MHz

Hmm, ok !

Do you know which modems 8ta are using in their trial ?

The problem is also that some of the modems (like the Alcatel, for example) will not be supported by most routers.

No, I wasn't accepted, but I hear it is wireless router. Possibly custom frequency, so no reason to start searching.... Sorry.
 
Hmm, this issue is quite complicated. For example, the E392 has the following variations :


HUAWEI E392u-12:

4G LTE Bands: FDD 800/1800/2600Mhz

3G UMTS: 900/1800/2100Mhz



HUAWEI E392u-21:

4G LTE Bands: FDD TDD 2600Mhz

3G UMTS: 900/2100Mhz



HUAWEI E392u-22:

4G LTE bands: FDD 2600/2100/1800/900/DD800Mhz

3G UMTS: 900/1800/2100Mhz



HUAWEI E392u-X?:

4G LTE bands: FDD 700B13/2100Mhz

3G UMTS: 900/2100Mhz



HUAWEI E392u-92:

4G LTE bands: TDD 2300/2600 Mhz

3G UMTS: 900/2100Mhz


HUAWEI E392u-6:

4G LTE bands: FDD 2600/2100/1800/900Mhz

3G UMTS: 900/2100Mhz


HUAWEI E392u-9:

4G LTE bands: TDD 2500Mhz

3G UMTS: 2100Mhz



HUAWEI E392u-511:

4G LTE bands: FDD 2600Mhz

3G UMTS: 2100/900Mhz


So how do you know which one is best for this market, assuming that one is going to use Vodacom, Cell C and 8ta ???

The HUAWEI E392u-22 seems like a good solution, but how does LTE DD800 differ from LTE FDD800 ?
 
It looks like there are the same things. FDD800 refers to LTE-FDD technology on 800MHz band and DD800 is a commercial name of 800MHz band allocated for LTE-FDD in EU.
Terms for LTE-xDD:
FDD - Frequency Division Duplex (upgrade path from WCDMA networks)
TDD - Time Division Duplex (upgrade path from TD-SCDMA, in China known as TD-LTE)

OK, thanks, I am going to try to get the E392u-22 (FDD 2600/2100/1800/900/DD800Mhz).

Should handle Vodacom and Cell C, don't know if it will work with 8ta.

Don't really care about MTN, I have zero MTN reception of any kind.

Until we know which frequencies are going to be used, there is not much point in jumping on the LTE bandwagon. Till then I am going to stick to my K 4605 modem.
 
No, I ordered a Huawei E398 modem that supports LTE in the 800 / 1800/ 2600 MHz bands.

I know that it will not support Cell C and 8ta, so I may have to get another one later.

That 2300MHz frequency that 8ta may use is a problem, very few modems support that.

My E398 will only work with Vodacom and MTN, and neither have attractive data rates.
 
Where did you get the E398 from and how much did it cost? Could you not source the E392?
 
Look at the Huawei E3276, there is a model that covers LTE 800 / 900 / 1800 / 2100 / 2600.

Everything except 8ta.

What I hear this is frequency assigned for testing purpose.
What will be a final, maybe ICASA knows...
Secondly, lets say you managed to buy a modem for this frequency. You go to the 8ta outlet, pickup SIM card just to discover that your SIM is not provisioned for LTE and nobody will do anything in this matter, as they don't want uncontrolled tower load under testing.
These are surprises waiting for you.
 
Jola,

Thanks for the advice. I am planning on getting the Huawei E392u-22 to use with a Mikrotik 433UHA.

I hope that works. I have the CellC Giga 200 package and although CellC has not yet rolled out LTE (at least not where I live) I figured I would try to future proof as much as I can at this stage.

The biggest challenge is where to buy the E392u-22 here in Joburg. I would appreciate any advice.
