3. Router Description

Cellular router SmartStart is designed for wireless communication in mobile networks that
use traditional cellular technologies. The primary purpose of this router is its use in the newest
Category 4 (Cat.4) services on the cellular LTE network.

3.1 LTE Category 4 (Cat.4)

LTE Category 4 (Cat.4) is the next step in 4G LTE device capability. Cat.4 rated SmartStart
routers are capable of achieving typical speeds in 4G coverage areas where the network is
enabled with 20 MHz of contiguous spectrum. The peak downlink data rate for a Category 4
is approximately 150 Mbps. Also in the uplink, LTE Category 4 provides a peak data rate of
50 Mbps.

3.2 Basic HW Information

As a standard, the SmartStart router is equipped with one Ethernet 10/100 Mbps, one
serial interface RS232, one binary input and one output. SL304 also contains two readers for
3 V and 1.8 V SIM cards, which are placed on the rear panel of the device. The router can
be equipped with a WiFi module, but this must be part of the initial configuration – it cannot
be assembled to the router at some point in the future. The SmartStart router is supplied in a
plastic casing.

3.3 Configuration and Diagnostics

The router can be configured using a password-protected Web interface. The web interface
provides (after logging in) detailed statistics about the router activities, signal strength, detailed
system logs etc. This device supports the creation of VPN tunnels using technologies IPSec,
OpenVPN and L2TP for secure communications. There are also supported functions such as
IPv6 (the latest revision of the Internet Protocol), DHCP, NAT, NAT-T, DynDNS, NTP, VRRP,
control by SMS, primary connection backups and many other functions are also supported.
Other diagnostic functions ensuring continuous communication include automatic inspec-
tion of PPP connection offering an automatic restart feature in case of connection is lost, or
hardware watchdog which monitors the status of the router. Using a special window (start up
script window) you may insert Linux scripts for various actions. For some applications is the
key possibility to create several different configurations for one router which can be switched
as needed (e.g. using SMS or status of the binary input). Cellular routers may automatically up-
date configuration and firmware from server. This allows mass reconfiguration of many routers
in one time.
