FAQ
What wireless standards does the SmartFlex SR305 support?
The SmartFlex SR305 supports Wi-Fi 4, which includes the IEEE 802.11a, 802.11b, 802.11g, and 802.11n wireless standards. This provides compatibility with a wide range of Wi-Fi devices while offering dual-band operation with support for both 2.4 GHz (ISM band) and 5 GHz (UNII band) frequencies for flexible deployment in different regulatory environments.
How many SIM cards can this router support simultaneously?
The router supports dual SIM cards of Mini size, allowing for cellular redundancy or the use of different mobile carriers. This dual SIM capability enables automatic failover between cellular connections if one network experiences issues, ensuring continuous connectivity for critical industrial applications where network uptime is essential.
What cellular networks is this router compatible with?
The SmartFlex SR305 supports GSM networks on 850 MHz, 900 MHz, 1800 MHz, and 1900 MHz bands, with cellular data connectivity for LTE, HSPA+, UMTS, EDGE, and GPRS technologies. This broad compatibility ensures the router can connect to most mobile networks worldwide, from modern 4G LTE networks to legacy 2G and 3G systems where cellular infrastructure varies.
How is this router mounted in industrial environments?
The router is designed for DIN rail mounting, which is the standard mounting system used in industrial control panels and electrical enclosures. The included DIN holder allows for secure installation on 35 mm DIN rails, making integration straightforward in manufacturing facilities, utility substations, and other industrial settings where equipment must be organized efficiently within limited cabinet space.
What wired connectivity options does the router provide?
The router offers five Fast Ethernet ports total: four network RJ-45 ports for connecting local devices and one broadband RJ-45 port for WAN connectivity. All ports operate at Fast Ethernet speeds (100 Mbps), providing reliable wired networking for industrial equipment, computers, and other devices that require stable connections in environments where wireless may be less reliable.
Does this router support VPN connections for secure remote access?
Yes, the SmartFlex SR305 includes VPN support, enabling secure encrypted connections for remote access to the network or for creating site-to-site tunnels between locations. This VPN capability is particularly valuable for industrial applications where sensitive data must be transmitted securely over public networks, such as remote monitoring of critical infrastructure or secure access to control systems from off-site locations.
