Dtac 4G has arrived in my area. Hooray?

I'm not sure, because my sim is in an aircard, and I haven't seen an aircard that supports LTE so far.

By the way, since I have a 3G router, does that mean I will have to upgrade my router as well to make use of a LTE aircard?

Any suggestions?

Not if the Router support the USB modem. They have them here, but they are a bit overpriced. You can pick up a suitable mobile WiFi 4G modem in the UK for 1000 baht. here, they would cost more than double.

From what I can gather from the specifications is that my router doesn't support such an aircard.

So I think the best solution would be to purchase a 4G modem/router in which I can insert a sim card, right?

My goal is that the internet can be accessed over the LAN from different rooms in the house. Is that possible with a MIFI device ?

If I conne3ct a MIFI device to my network hub, can every room connect to it, or do I need a router between?

While "MiFi" is a Novatel Wireless registered trademark brand, other similar devices will go by some combination of the names, "Mobile, Portable, Pocket, Personal, Private WiFi Hotspot" and "3G / 4G / LTE / Mobile Internet" classification.

The one primary 'feature' of these devices is that they allow a Mobile Internet connections to be shared to several WiFi devices (though, they limit the number of concurrently connected devices to 5 or less). Many of the "Portable Hotspot" devices can also be connected to a computer via a Micro-USB connection though doing so disables the Wi-Fi networking, converting the device into a traditional single-client modem.

You still might be able to find one of these devices with an Ethernet connector that would allow you to patch it into your current home network, but the device itself will limit its usefulness to only a small handfull of Ethernet devices that can concurrently connect to it. A workaround using an additional NAT router prior to connecting to your existing network 'might' work (doing the SAME THING as your current 3G stick and 3G router do now).

Thanks, in practice it will never be more than 3 connections at the same time. Are you aware of 4G device with ethernet port?

Haven't seen one in Thailand.

The thing about Ethernet ports on these devices will be MOST ARE PREWIRES to ONLY ACT AS A WAN INPUT, or can be configures to act as a LAN OUTPUT.

So even if the device HAS an Ethernet port, it may not do what you want it to do (WAN vs LAN operation).

A quick Internet search finds:

D-Link DWR-921 3G/4G/LTE Router has an actual 3G/LTE built-in modem

3G: UMTS/HSDPA/HSUPA band 900/2100 MHz Power Class 3

4G/LTE: band 900/1800/2600/800 MHz <- note the bands covered, or not covered

4G LTE FDD 800/850/900/1800/2100/2600 MHz

Currently LTE in Thailand is restricted to band 1 2100MHz. But 1800 MHz (band 3 I think) should be available in the next few years :-D
