Modem Performance/Specifications

The EM7455/MC7455 is a Category 6 LTE modem. It is capable of 300Mbps downward and 50Mbps upward.
Real world, you lot are unlikely to ever see much more 230Mbps, even on Sprint Carrier Aggregation of Band 41+41 (40MHz total).
These are my peak results so far (B2+B12, 30MHz full):
Higher speeds will require a modem capable of 3CA (Three Carrier Aggregation) such as the em7565
- EM7565 allows 3CA of B2+B12+B30 for a total downlink of 40MHz on approximately 60% of AT&T towers (Assuming yous are close and have a strong signal).
- LTEFix at present offers the em7565 pre-flashed to the latest firmware. If the process of flashing seems daunting, I suggest you buy through them and pay for the flashing service as yous volition receive a modem already in a usable country.
- These are my top results and so far (B2+B12+B30, 40MHz total):

Which Modem to Buy

If your Laptop has a M.2 WWAN slot, get the Dell DW5811e em7455 and modify its identity according to your needs.
- ~$30 Dell DW5811e em7455
- This model (typically) supports Bands 29 and thirty, unlike the Lenovo Branded Modem.
- When purchasing the Dell, I would recommend you get a product model. Engineering Samples will sometimes contain an early (SWI9X30C_00.08.02.00) firmware that tin be a regal pain to flash due to AT!BOOTHOLD not being implemented.

Adapters and Antennas

Get USB adapter with SIM slot for modem
- $26, shipped from Texas. Includes minor 3dBi antennas.
  - USB To NGFF Yard.2 Key B Adapter Enclosure With SIM Card Slot
If you are at the edge of coverage and need something better, wait for 700-2700 MHz antennas with SMA connectors.
- Purchase some $0.75 SMA Female To RP-SMA Male Adapters if y'all purchase antennas, just to exist certain you lot can use what you get.
  - SMA vs RP-SMA, learn the divergence
- Log-Periodic antennas offer splendid proceeds for a depression price and small footprint.
  - $29 698-2700MHz Yagi Radome 9dBi-11dBi 4G LTE Directional Antenna
- Omni-Antennas tin boost overall indicate if you already have decent service and just want dandy service.
  - While not explicitly tuned to Ring 12/13/17, a pair of 2.4GHz 9dBi RP-SMA Antennas will provide a nice bespeak boost.

Create Attainable COM Port

How to Calculate Bitmasks to Lock LTE Bands

When you encounter something like AT!Ring=10,"B2B4B5B12",0,000000000000081A, you lot may wonder how that number on the cease is derrived. It is a bitmask.

Starting time, unlock Advanced/Admin mode:
- AT!ENTERCND="A710"
Adjacent, bank check the bitmask options for your specific modem. There volition be variations betwixt modems, so ever check what is actually bachelor on your modem and reference that tabular array.

Now, if we desire to create a mask that combines 3G B2+B1 and LTE B3+B7+B20, we do the following:
- Look at the GW Band column for 3G ring bit codes, annotation that:
  - 0000000000400000 - B1 (2100)
  - 0000000000800000 - B2 (1900)
- Add together the two masks, since we are dealing with hex, 10 = A, eleven = B, 12 = C, and then on:
  - 0000000000C00000 - B1+B2
Perform the same task for the LTE column (discover that the mask is different than the 3G mask):
- Look at the LTE Band column for LTE band bit codes, note that:
  - 0000000000000004 - B3
  - 0000000000000040 - B7
  - 0000000000080000 - B20
- Add together together the 3 masks:
  - 0000000000080044 - B3+B7+B20
To necktie it birthday, we upshot our custom band command:
- AT!Band=ten,"B2B1-B3B7B20",0000000000C00000,0000000000080044
Finally, we set out custom band in slot x:
- AT!Ring=09
