Wi-Fi Mini-Physical Interface Module Overview
The Wi-Fi Mini-Physical Interface Module (Mini-PIM) for branch SRX Series Services Gateways provides a branch-in-a-box
solution (which includes an SRX Series device, LTE, and wi-fi) for retail and small office deployments. The Mini-PIM has
an embedded enterprise-class wireless system-on-chip (SOC) that supports the 802.11ac Wave 2 wireless standards. The
Mini-PIM is backward-compatible with 802.11a, 802.11b, 802.11g, and 802.11n.
The Mini-PIM supports the following key features:
•2x2 MU-MIMO—Enables transmission of data to multiple clients simultaneously.
•Dual radios—Provides concurrent dual bands of 2.4 GHz and 5 GHz. The radios operate in any one of the supported
radio modes. You can configure each radio to support connectivity from one type of client or different types of clients.
•Virtual access points (VAPs)—Allows you to segment the WLAN into multiple broadcast domains that are the wireless
equivalent of Ethernet VLANs. A single access point is segregated into multiple individual VAPs, simulating multiple
access points in a single system.

NOTE: You can configure up to eight VAPs on each radio.
•Configurable transmit power—Enables you to configure the transmit power for each radio on a percentage basis. By
default, the Mini-PIM assigns 100 percent power to each radio at startup to provide maximum coverage.
•Wireless security for client authentication—The Mini-PIM supports the following authentication methods:
•Wi-Fi Protected Access (WPA) Personal, which includes AES-CCMP with preshared key authentication.
•WPA Enterprise, which includes AES-CCMP with RADIUS server authentication.
•MAC authentication, where wireless clients are allowed or denied network access based on their MAC address.
The Mini-PIM is supported on the SRX320, SRX340, SRX345, and SRX550M devices and can coexist with other Mini-PIMs
supported on these devices.

Channels and Frequencies Supported on the Wi-Fi Mini-PIM
The Wi-Fi Mini-PIM supports channel bandwidths of 20 MHz, 40 MHz, and 80 MHz. The 2.4 GHz radio supports 20 MHz
and 40 MHz channel bandwidths, and the 5 GHz radio supports 20 MHz, 40 MHz, and 80 MHz channel bandwidths. You
can configure the bandwidth by using the set wlan access-point ap-name radio [1|2] radio-option channel bandwidth
bandwidth command.
NOTE: You can configure the 80 MHz channel bandwidth only on the 5 GHz radio.
The default channel bandwidth is 20 MHz for the 2.4 GHz radio and 40 MHz for the 5 GHz radio. Setting the bandwidth
to 40 MHz or 80 MHz reduces the number of available channels for use.
Table 5 lists the channels supported on the 2.4 GHz radio.

Dynamic Frequency Selection
Dynamic Frequency Selection (DFS) enables use of 5 GHz frequencies that are typically reserved for radars. In countries
where DFS is required, the Wi-Fi card performs appropriate checks for radar. If radar is detected on a channel, the access
point selects a radar-free channel and performs a 60-second availability check before operating on that channel.
DFS is enabled by default. You can disable DFS by using the dfs-off option:
set wlan access-point ap-name radio 1 radio-options dfs-off
NOTE: Only the 5 GHz radio (radio 1) supports DFS.
You can configure the DFS settings in any of the following ways based on your requirement:
DFS enabled (default)
•If you set the channel number to auto, the access point selects the channel from the list of DFS and non-DFS channels.
If the access point selects a DFS channel and detects radar on the channel, it switches to another channel automatically.
•If you set the channel number manually to a DFS channel and if the access point detects a radar on this channel, it
switches to another channel automatically;
DFS disabled (dfs-off configured)
•If you set the channel number to auto, the access point selects the channel from the list of non-DFS channels.
•If you set the channel number manually, you can configure either a DFS or non-DFS channel. If you configure a DFS
channel with DFS disabled, a warning message appears when you commit the configuration.
