It looks like we can expect faster wireless connections in the near future: Japanese electronic parts maker Rohm yesterday announced [JP] it has developed a chip that reached a wireless data transmission speed of 1.5 gigabits per second in experiments, the highest level ever. And according to the company, even 30Gbps will be possible in the future.The semi conductor device uses terahertz waves for data transmission, has a micro antenna attached to it and is 2cm long and 1cm high (size of the module).
