We have recently reviewed LTE Advanced (which will deliver up to 1 gigabit per second) and is being deployed starting in 2013 and the new multi-gigabit wifi deployments.
Here is a list of technologies which will enable even more access and higher speed wireless communication.
1. Chamtech has developed the “Spray-On Antenna” to assist intelligence gathering operations by concealing the antennas for equipment that needs to transmit and or receive in frequency bands from 1 MHz through 6.4 GHz. The antenna paint has thousands on nanocapacitors that are far more efficient (so they do not build up heat) than antennas with wires. This technology can boost wireless range by a large amount. RFID range is boosted from 5 feet to 700 feet.
2. DARPA’s 100 Gb/s RF Backbone (100G) project intends to develop a fiber-optic-equivalent communications backbone that can be deployed worldwide. The goal is to create a 100 Gb/s data link that achieves a range greater than 200 kilometers between airborne assets and a range greater than 100 kilometers between an airborne asset (at 60,000 feet) and the ground.
3. American and Israeli researchers have used twisted, vortex beams to transmit data at 2.5 terabits per second. This twist encoding technique is likely to be used in the next few years to vastly increase the throughput of both wireless and fiber-optic networks.
According to Thide, OAM should allow us to twist together an “infinite number” of conventional transmission protocols without using any more spectrum. In theory, we should be able to take 10 (or 100 or 1000 or…) WiFi or LTE signals and twist them into a single beam, increasing throughput by 10 (or 100 or 1000 or…) times.
The next task for Willner’s team will be to increase the OAM network’s paltry one-meter transmission distance to something a little more usable. “For situations that require high capacity… over relatively short distances of less than 1km, this approach could be appealing. Of course, there are also opportunities for long-distance satellite-to-satellite communications in space, where turbulence is not an issue,” Willner tells the BBC. In reality, the main limiting factor is that we simply don’t have the hardware or software to manipulate OAM. The future of wireless networking is very bright indeed.
4. NTT is using elastic optical path networks to achieve 1 terabit per second communication and others are developing graphene-Based Optical Modulators to boost communication speed by ten times.
5. NTT demonstrated one petabit per second transmission over one optical fiber over a 50 kilometer distance and are working to get another ten times boost in speed.
