Navigating tough terrains
MetroCarrier’s customer requested a symmetric service at 20 or 50 Mbps to provide high-performing, stable internet connectivity. However, the nature of the terrain meant that terrestrial infrastructure, such as fiber optic cables, wasn’t an option. The hard-to-reach and awkward position of the location requiring the connectivity upgrade, in the hills of Guadalajara, presented a challenge for establishing a network.
Infinet Wireless and GTMS, to provide connectivity at distances of up to 20 km whilst overcoming obstacles such as obstructive hills in the area, decided to install a solution using a mixture of solar panels and wireless links. An orography analysis, measuring the location’s topology, was performed with National Institute of Statistics and Geography’s (INEGI) and NASA’s Shuttle Radar Topography Mission’s (SRTM) digital databases to select the ideal location for the repeater device.
Subsequently, a 9m braced tower and solar electric system – equipped with solar panels, a battery bank and an inverter – was installed at the ranch. At CTC Obregón, the tower was increased in length from 15m to 24m. At the San Joaquín ranch, a mast and solar electric system inverters were. installed
To enable the transport links in the Wireless Access Network (WAN), and to extend coverage of the Local Access Network (LAN) for end users at the ranch, 5.8 GHz free band Wi-Fi links were installed. This enables the end user to benefit from enhanced speeds and reduced channel interference
“The hilly terrain presented a significant challenge when setting up the links. However, thanks to our expertise and experienced workforce, we’re able to operate in terrains and deliver networking solutions in locations considered unreachable. The engineering team after, assessing the feasibility of the project, was able to successfully assign a work team to complete what the project to the standard expected by MetroCarrier,” said Mario De La Rosa, CEO of (GTMS) Global Telecommunications Microwave Solutions.
The requirements of the customer were exceeded thanks to the network design and high performing solutions. GTMS successfully designed a network that delivered the symmetric 20 or 50 Mbps service requested by the customer with a record implementation and installation time. Furthermore, the customer received a throughput capacity of 300 Mbps, exceeding their expectations of the service.
The quality of Infinet Wireless’ solutions guaranteed stability and high performance. Infinet Wireless used a selection of links to meet the requirements for the network. In CTC Ciudad Obregon, a 17.75 km2 ranch, a repeater was installed with external 32 dBi antennas and Infinet’s InfiLINK XG point-to-point (P2P) solution. At the San Joaquín, a repeater was used on the 2.26 km2 ranch, with 23 dBi antennas and the InfiLINK 2x2 LITE P2P equipment. The cost-effective medium capacity LITE series can be upgraded to Infinet Wireless’ PRO solution, meaning the customers’ capacity can be expanded.
All of the links used have an availability of 99,999%.
The customer will also benefit from a continuous service. The network has a 72-hour backup provided by solar panels and wireless links that can work regardless of weather conditions. Energy consumption savings were made, meaning the customer made significant cost savings as a generator isn’t needed to continuously power the network.
“In the selection process, despite evaluating a number of competitors’ solutions, the scope and stability of Infinet Wireless’ solutions stood out as the best option. So far we have 60 links connected as a result of the project. We’re impressed by the reliability of both the links and the Infinet Wireless team and hope to continue growing with the brand,” said Sergio Zepeda, Director of Engineering for MetroCarrier, Guadalajara, Mexico.
Zepeda expressed "the trust and support of Infinet Wireless solutions will allow us to continue with this quality margin and open new markets".
Although here was a tight time frame to complete the work, the partners involved were able to complete the project on schedule and to a standard that impressed the customer.
“With Infinet Wireless’ solutions, we have managed to meet the needs and challenges of our customers in the region. The obstacles presented by MetroCarrier’s request have been overcome and we will continue to implement more projects hand in hand with Infinet Wireless in the future,” added GTMS’ De La Rosa.
GTMS is a has more than 15 years of experience in various Telecommunications projects throughout Mexico. This company has been a provider of services and technological solutions for all sectors, has managed and installed Infinet Wireless solutions for more than 10 years. For the El Rancho project, GTMS decided to use Infinet Wireless for its scope and stability, so far, there are more than 60 links for MetroCarrier, others for carriers and end users.
