A company called RigNet Inc. has launched what it says is the first deep water 4G LTE (News - Alert) service. The company is delivering it to its oil and gas industry customers in the remote area of Green Canyon field. That’s on the Gulf of Mexico.
RigNet has also tripled the capacity of its wireless MPLS network as part of its network enhancement. The company has been operating its network in the Gulf of Mexico for more than two decades. It outfits customers from Texas to Alabama with connections at rates of up to 100 megabits per second.
This company represents just one recent example of exciting breakthroughs we’re seeing related to underwater networking.
For example, Facebook (News - Alert) and Nokia recently announced record-breaking results from their field trials of submarine cable transmissions.
A field trial on a 5,500-kilometer submarine cable running between New York and Ireland leveraged shaped 64 QAM technology to achieve 7.46 b/s/Hz spectral efficiency. That's a record, topping the next best results in this area by nearly two and a half times, according to Facebook and Nokia (News - Alert).
“This field trial with Nokia demonstrates that the scalable optical technology of PCS together with narrow linewidth laser sources can achieve capacities extremely close to the Shannon limit,” commented Stephen Grubb, Facebook’s global optical network architect. “This ensures that we are both maximizing our investment in submarine cable systems, as well as continuing to drive the cost per bit of submarine transport lower."
In a different trial, this one involving a 11,000-kilometer round trip submarine transmission, 64 QAM techniques enabled the companies to achieve record spectral efficiency of 5.68 b/s/Hz. This field trial also marked the first demonstration of 200 and 250 gigabit per second wavelengths and 16 QAM.
Meanwhile, Microsoft (News - Alert) has been testing fully automated data centers that are underwater. Putting data centers underwater can help with cooling, given data centers require a lot of cost and energy for climate control. But having an underwater data center creates challenges from a human resources perspective, so the company is experimenting with robots to handle repetitive tasks such as switching out failed equipment.
