How to Openline/Unlock Globe 4G LTE B593s-22 LTE MODEM

This tutorial will teach you on how to openline your Huawei B593s-22 Globe LTE Modem. Why unlock? At default you can only use Globe LTE SIM, through unlocking you can use any SIM you want as long as it conforms the supported frequency of the modem.


Tutorial: Phase 1


1. Go to your web gui, on browser 192.168.254.254 and login using user user/ pass @l03e1t3

2. Copy your device imei (ex. 86009102399XXXX) - on product information tab.

3. Generate the unlock code by going to http://huaweicodecalculator.com/new-algo/
4.  Use your Google account and hit +1 be sure to encode every details.
5. Put your IMEI and copy the red generated NEW ALGO(usually 8 digits)
6. Insert any SIM except Globe (SMART recommended)
7. Log-in again to 192.168.254.254 just ignore the message invalid SIM
8. Use the user account again user/@l03e1t3

Tutorial: Phase 2

1. Download the config file at https://goo.gl/OAz9oe

2. Upload the config file by going to system - scroll down till you see "Upload Configuration File", click browse choose file then upload.











3. The LTE modem will reboot

Tutorial: Phase 3

  1. This time go to 192.168.1.1 on your browser
  2. Log-in as admin user admin/ pass password123
  3. Navigate to INTERNET tab and paste the NEW ALGO code.
  4. Your Huawei B593s-22 is now openline.
Using SMART LTE SIM: APN and Settings
  • To create an APN go to internet, next apn management, and add profile. For profile name you can use any name doesn't matter, APN is internet leave everything else blank.
  • Go to network mode and select the available network in your area WCDMA or LTE only. Don't forget to switch profile when changing SIM's.
  • Explore and tweak your modem's WIFI and password as you desire.

Single Mode vs Multi Mode Fiber Transceivers


The key difference between SMF and MMF?
...Distance and cost!
  • Single Mode Fiber has a greater distance potential and can support runs between 2 meters and 10,000 meters.
  • Multimode generally has a reach up to ~550 meters, whereas single mode has the potential to reach 10,000 meters (40,000 meters with ER)
  • Single mode fiber -> lower power loss characteristic than multimode fiber, which means light can travel longer distances through it than it can through multimode fiber.
Costs
  • The optics for SMF are twice the cost of MMF optics.
  • BUT when installed as part of a project, the extra cost of SMF is negligible compared to MMF.
  • The fragility and increased cost to produce single mode fiber makes it more expensive to use, which is why multimode is typically used when you don’t need the distance of single mode.
Speed
Both single-mode and modern multi-mode fiber can handle 10G speeds.
The distance requirement is critical
  • Multi-mode which can get you 300-400 meters.
  • Single-mode can get you 10km, 40km, 80km, and even farther – you just need to use the appropriate optic for the distance required. Prices go up accordingly.
Compatibility issues:
  • They are not compatible.
  • You cannot mix multimode and single mode fiber between two endpoints.
  • The optics are not compatible either.
How they work:
  • Multi-mode fiber (MMF) – uses a much bigger core and usually uses a longer wavelength of light. Because of this, the optics used in MMF have a higher capability to gather light from the laser. In practical terms, this means the optics are cheaper.
  • Single-mode fiber (SMF) has much tighter tolerances for optics used. The core is smaller and the laser wavelength is narrower. This means that SMF has the capability for higher bandwidth and much longer distances in transmission. Single-mode fiber has a smaller core (9 micron), resulting in less light diffraction over distance than multimode fiber (50, 62.5 micron).
Are single mode transceivers a better option for the future?
  • Using only single mode lets you use one fiber type for everything (fewer optics, cable types to spare)
  • No likelihood of obsolescence (eg, OM3 seemed like it was current for ~3 years)
  • Offers single-pair options for 40 & 100g
  • Offers single-fiber options at 1 & 10g
  • Although the optics are more expensive they’re < 2x while offering much longer reach (remember to buy OEM optics, not rebadged)
  • With SMF it also means you won’t need to rip out your MMF fiber plant to upgrade speeds in a few years.

How to Configure Huawei B593 LTE CPE 4G Router

In order to configure B593 gateway, you should access Web-Based Utility at frist. It is a web browser-based configuration interface that allows easy device setup, configuration and management through Internet browser. Here you can take a detail view about how to do the configuration settings for B593.

Steps to configure B593 gateway

1Access the configuration GUI

1. From your computer, launch your Web browser. and type http://192.168.1.1 in the address bar.
2. Select the Admin radio button and type the Admin password ( At the back of the B593 router, you could see the router's wesite portal and password), press Enter or click Login.


2Do configuration setting with Setup Wizard

1. In the left hand column, click the Setup Wizard. Then click Next.
2. The Wireless and Wireline settings appear. Note: It is recommended to keep the default settings.

3. Click Next and the WLAN (Wireless Local Area Network) screen appears.
Ensure the WLAN checkbox is selected to enable Wi-Fi on the Smart Hub.
Select the desired working Mode for the Wi-Fi network.
Note: 802.11b/g/n is most compatible with other devices. 802.11n has the greatest range.
Select the Channel. It is recommended to select Auto.
Enter a name for your Wi-Fi network in the SSID field.

4. Click Next and the WLAN Security settings appear.
Select the Security type. WPA2-PSK is recommended.
Enter a network password in the WPA-PSK field.
Select the WPA encryption method. AES is recommended.

5. Click Next and review your settings and click Submit to confirm your configuration.
After these settings, you have fininshed the configuration for B593 LTE.
