This document discusses a 4G smart trails system solution that uses 4G industrial routers and a management platform to create a stable wireless network for outdoor environments. The solution allows for automatic identification and recording of individuals exercising on smart trails through non-sensing and face recognition equipment. It also provides convenient operation, maintenance, and supervision for city managers while reducing network configuration and maintenance costs.

1. Use 4g Router to Build Smart Trails System
Smart city is an urban model that utilizes information and communication technology
to realize the optimization and coordination of urban management, services, life and
environment.
Recently, an innovative 4G smart trails system solution has brought new changes to
the urban fitness environment. The solution mainly uses E-Lins' 4G industrial router
H685 series and NMS management platform, which can quickly establish a stable
wireless network in an outdoor environment and realize real-time data collection and
transmission. The solution uses non-sensing collection equipment and face
recognition equipment to automatically identify and record sports people. Sports

2. people can enjoy digital fitness services through mobile APP or check their exercise
status. This solution also provides city managers with convenient operation,
maintenance and supervision methods, reduces the cost of network configuration and
maintenance, and improves efficiency and security.
E-Lins' 4G industrial router H685 series is the core communication hardware of the 4G
smart walkway system solution. It supports various outdoor networking methods. The
industrial-grade design can cope with complex environmental changes and can
operate stably in harsh environments of -30~70°C. Combined with the problem that
the network cannot be fully deployed outdoors, the 4G industrial router H685 series
supports multiple Internet access methods. Users can freely choose 4G/3G, wired, and
wireless methods based on the regional conditions, and support dual-link broadband
network and 4G network at the same time. The work is backed up with each other to
ensure that the network is stable and online.
Choosing the 4G network mode in the outdoor environment can save the cost and
time of private network wiring. The industrial router H685 series is plug-and-play, used
with the Internet of Things traffic card, the network is stable, the optional package is
convenient for centralized management, the tariff is favorable, and the traffic is
sufficient , which can effectively reduce the operator's network configuration cost.
Industrial 4g router with ethernet, like smart trail system terminals, also need to be
used in harsh outdoor environments exposed to sunlight and rain. For this reason, the
industrial-grade design of the H685 series uses a metal shell material to facilitate heat
dissipation, supports wall-mounted mounting ears for fixed installation, provides
5V~40V DC wide voltage power supply (5-60V optional), has IP30 protection level, and
the power during normal operation Less than 3W, these configurations meet the
networking requirements of outdoor use scenarios, are safe and stable, and the
network continues to operate.
During long-term and high-intensity operation, regular maintenance and management
are essential. When performing necessary equipment network maintenance, no
personnel are required to be present. Operators can quickly and remotely manage on-
site equipment directly through the NMS management platform. It is also possible to
set individual routers in real time through the public network IP to grasp the network
and operating status of the on-site industrial routers, which can effectively ensure the
continuous working status of smart trails and industrial routers. The labor cost of
system equipment operation and maintenance.
