Unified Global Variants for SKYRS Pakistan

Unlike region-locked hardware, the EG25-G Mini PCIe supplied through SKYRS features a true universal radio profile. This allows local systems to access every operating frequency assigned within the Pakistani territory (including Jazz, Zong, Telenor, Ufone, and Special Communications Organization – SCO).

Product Configurations Available:

• EG25-GGB Mini PCIe (Standard Production Profile)

• EG25-GGC Mini PCIe (Advanced Custom Audio/Ecosystem Profile)

Supported Local Operating Bands:

• LTE-FDD Carrier Pathing: B1 (2100 MHz), B3 (1800 MHz), B5 (850 MHz), B7 (2600 MHz), B8 (900 MHz), B20, B28 (700 MHz APT)

• LTE-TDD Carrier Pathing: B38, B39, B40 (2300 MHz), B41

• 3G allback Matrix (WCDMA): B1, B2, B4, B5, B6, B8, B19

• 2G Fallback Matrix (GSM): B2, B3, B5, B8

Network Versatility Factor: The native implementation of FDD Band 3 (1800 MHz) and FDD Band 1 (2100 MHz) covers the bedrock 4G deployments of Zong and Jazz, while FDD Band 28 (700 MHz) support enables maximum deep-indoor and underground penetrating links where higher frequencies drop out.

Deployment and On-Site Installation Guide

The standardized Mini PCIe card structure drastically reduces integration overhead compared to surface-mount components, making it ideal for immediate field drop-ins.

Physical Integration Method

1. Card Insertion: Align and fully seed the EG25-G card into the standard Mini PCIe slot on your industrial PC (IPC), single-board computer, or EXVIST specialized USB adapter dongle base. Secure the module down via twin retention screws.

2. RF Interconnect Layout: Pop matching U.FL/IPEX miniature coaxial leads onto the card’s surface connectors (labeled Main, Rx-Div, and GNSS). Route these to external chassis-mount SMA connectors using high-isolation, low-attenuation pig-tails.

3. Antenna Configuration: For peak MIMO downlink efficiency and sustained data packet rates, attach dual broad-spectrum 4G LTE antennas. Keep a structural separation of at least 20cm between the main and auxiliary antennas to eliminate cross-talk interference.

Subscriber Identification Integration

• Slide an active M2M SIM card into the push-push or tray-style SIM holder attached to the host platform’s native Mini PCIe interface lines.

Configuration and Operating System Interactivity

The EXVIST EG25-G Mini PCIe translates inner modem functions to host architectures through virtual serial mapping and high-speed network adapters over the USB bus.

Driver System Setup

• Target Infrastructure Support: Universal compatibility with Windows 7/8/8.1/10/11, Linux Kernels (2.6 through modern 6.x releases), and Android 4.x to 11.x platforms.

• Core Network Adapters: Leverages standard QMI_WWAN, GobiNet, or MBIM driver abstractions to expose direct broadband network interfaces.

Initial Communication and Carrier Onboarding (via AT Commands) Establish a connection session over your serial terminal software utilizing the default baud configuration of 115200 bps:

• Test Internal Core Responsiveness: AT -> Expect: OK

• Verify Internal Subscriber Card Presence: AT+CPIN? -> Expect: +CPIN: READY

• Register Carrier Access Point Name (APN): AT+CGDCONT=1,”IP”,”[Carrier_APN_String]” (e.g., “jazzconnect.pakistan” or “telenor.smart”)

• Read Radio Signal Characteristics: AT+CSQ -> Checks Received Signal Strength Indication (RSSI) parameters to verify structural antenna position.

• Check Local Operator Attaching Status: AT+CGATT? -> Returns +CGATT: 1 showing successful activation within the local packet data network.

Availability and Custom Staging Exclusively at SKYRS

The entire deployment ecosystem for EXVIST Quectel EG25-G Mini PCIe industrial hardware, along with matching evaluation testing boards and high-gain custom outdoor RF antennas, is available only at SKYRS within Pakistan.
