Before Lei Feng published an article, the modular mobile phone Google reality is not feasible, one of the most important point is, modular mobile phone cannot be realized by electronic signal, optical interconnection might be possible, but this technology is not mature. Optical interconnection chip is still under study, has invested huge funds. Intel optical technology has demonstrated impressive, should be on the market within 5 years. Eventually we will be able to make integrated circuits, optical interconnected, so as to achieve the communication of ultra high speed, then the modular mobile phone will be more feasible.

　　Now, we seem to be modular mobile phone from a step closer. Japanese researchers have developed a "Two-Fold Transmission Line Coupler" (T-TLC) of the non contact communication technology, can realize the non-contact communication between modules, and the size of the coupler is only 6mm2, very suitable for smart mobile phone module such as Project Ara.

　　At the end of 2014, there are Silicon Valley startups Keyssa released a "new type of non-contact connection technology of Kiss Connectivity", can let the system as long as close to each other that can quickly transfer data, to jump off the traditional design framework to be mechanical connector and cable transmission. Keyssa vice president of marketing Mariel van Tatenhove expects the production in the first half of 2015, there have been some mobile phone, tablet computer and personal computer makers are product design, is expected in the second half of 2015 is to be able to see the product market, reform the existing mobile device design and transmission mode.

　　When the product is truly epoch-making innovation of mobile phone, laptop or camera can come out? Let's rub one's eyes and wait.
