SAF – Reliable Industry Grade Wireless Solution for Egyptian Gas Company

Egypt, North of the Sinai Coast

Venue

Gas Drilling Rig
Onshore site located north of the Sinai Coast
Offshore platform is 52km away in the Mediterranean Sea

Solution Overview

SAF PhoeniX split mount radio system
Setup: 1+1 space diversity (SD) setup
Antennas: separate ODU with antenna for each site

Services

Communication of data of the gas well
Control and Access the DCS
Day-to-Day calls between staff on- and offshore

Problem

ATSI (Advanced Technology Solutions International) was called in to assist an Egyptian gas company to replace their existing satellite communications network. The system was ineffective with frequent downtime, huge delay time and insufficient bandwidth to carry the traffic. There are also high costs associated with running the satellite communications system.

Microwave link conditions were challenging due to distance, and interference due to water in the link path that can lead to inconsistent performance.

Project Details

ATSI decided to go with SAF PhoeniX split mount radio system:

Link distance: 52 km
Frequency: 7GHz
Setup: 1+1 space diversity (SD) setup
Antennas: separate ODU with antenna for each site

Solution

SAF Teknika hardware was utilized to provide the best performance. A 1+1 space diversity (SD) setup was used and a separate ODU with antenna was deployed for each site to provide best link performance. This setup meant that the receiver could then pick out the better of the two received signals at two antennas, significantly reducing link multipath interference problems as well as avoiding links with weak RF receiving signals. SAF links were installed at 135 meter height on the onshore tower and at 25 meter height on the offshore tower – therefore overcoming the distance issues.

Outcomes

Result

System reliability hit 99.999% with full redundancy
Downtime was reduced to 5 minutes or less per annum
The use of long-distance links is significantly more cost-effective
SAF system is easier to manage and maintain than previous satellite communication system
Full customer satisfaction as a solution was provided to overcome a challenging and critical installation that had a lot of environment barriers

Rapid Systems has been providing full-service Internet and Information Technology since 1996. To interconnect their network towers, they have been using licensed 11GHz microwave links with a capacity around 1 Gbit/s per link. In order to support their plans for expansion, they need to upgrade their links to support up to 10 Gbit/s moving forward. Rapid Systems considered E-Band as their solution, but the biggest challenge is that some of their towers exceed distances of 8 miles. Keeping the radios synchronized and deployment costs low would require an innovative solution.

The Hollinger Project was a huge undertaking as the historic mine site would have to be converted to an open pit mine. Some of the initial challenges would have to be overcoming the leftover structures of the mine, but the biggest challenge would be creating a wireless network that would be suitable for the site. While a public Wi-Fi network could suffice, there were security risks that ultimately made a private network for communications to be selected. With the security concerns noted, the next considerations would be the need for...

Since there are no cables running to the island, all connectivity is delivered through wireless means. The water reflection, tides, harsh weather, and other obstructions such as boats and trees can cause disruptions in the wireless stability on the island. The biggest issue is that during the summer months when the number of visitors surge, the island struggles to keep up with the increased demand and that poses a risk to the local systems.

Since the Public Safety DAS market is very mature with many competitors in Denver, there needs to be significant cost and feature considerations when bidding for a project as large as these two towers. One of the biggest issues with creating a competitive solution was the sheer size of the buildings, with over one million square feet to cover. Utilizing a fiber distributed DAS would be too costly and complex to cover heavy stairwells and enclosed garage spaces as well.
