Japan's Willcom has launched Bytemobile's embedded browser optimisation technology, which accelerates web browsing for handset subscribers, Digital Media Asia reported Tuesday.

Willcom launched the “Speed-up Service,” which increases download speeds by up to two times from current clientless service and up to four times from standard, unoptimised service, earlier this month.

Mobile customers can subscribe to the service for no additional fee, or subscribe to four different levels of optimisation with corresponding levels of screen image quality, according to Digital Media Asia.
