Wi-Fi Mini-Physical Interface Module Overview

Wi-Fi Mini-Physical Interface Module (Wi-Fi Mini-PIM) for SRX320, SRX340, SRX345, and SRX550M provides an integrated wireless access point —or wireless LAN— along with routing, switching, and security in a single device. Mini-PIM supports the 802.11ac Wave 2 wireless standards and is backward compatible with 802.11a/b/g/n. The Wi-Fi Mini-PIM can coexist with other Mini-PIMs supported on the SRX Series device.Table 1 provides a summary of the features supported on Mini-PIM.

Typical deployments for Wi-Fi Mini-PIM solution include:

Secure wireless LAN connectivity to endpoint devices of corporate users at remote branch offices as seen in Figure 1. 802.11ac, WPA2, 802.1X, and SSID-to-VLAN mapping features provide secure Wireless LAN connectivity.
Direct network connectivity to the enterprise Internet of Things (IoT) devices. The security features on the SRX Series devices secure the IoT devices.

The Mini-PIM inserted onto the SRX series device provides a secure wireless access point connection to multiple clients in a remote location. The following figure illustrates the secure LAN connectivity of Wi-Fi Mini-PIM.

Features Supported on the Wi-Fi Mini-PIM

Table 1 lists the key features supported on the Wi-Fi Mini-PIM.

Table 1: Wi-Fi Mini-PIM Features

Feature	Description
2x2 MU-MIMO	Enables transmission of data to multiple clients simultaneously.
Dual radios	Both radios of 2.4 GHz and 5 GHz bands are simultaneously supported. The maximum supported speed is upto 1.2 Gbps.
Virtual access points (VAPs) and VLAN features	Allows you to segment the WLAN into multiple broadcast domains that are the wireless equivalents of Ethernet VLANs. A single access point is segregated into multiple individual VAPs, simulating multiple access points in a single system. An access point supports multiple VLANs, which can be distributed across VAPs and radios. You can configure up to eight VAPs per radio. You can map up to 16 extended service set identifiers (ESSIDs) to individual VLANs. The VLANs from the Mini-PIM software map to VLANs on Junos OS.
Co-existence of interfaces	The Wi-Fi Mini-PIM coexists with 4G LTE, VDSL, T1, and serial interfaces.
Client authentication methods	Client authentication methods supported are Wi-Fi Protected Access (WPA) Enterprise (WPA2 standards) and Wi-Fi Protected Access (WPA) Personal (AES-CCMP cipher suits and WPA2 standards).

Benefits of Using the Wi-Fi Mini-PIM

Provides advanced security capabilities (WPA personal and WPA enterprise authentication methods).
Simplifies network design, and provides unified management.
Supports end-to-end segmentation from user to applications with ESSID-to-VLAN mapping.
