　　新的和显著的移动世界大会射频工程师的发展

　　在整个为期四天的2013世界移动通信大会（MWC）的证据是大量的在巴塞罗那，西班牙，全世界的无线移动生态系统的不断扩大而搁置。在移动设备、产品集成电路和无线技术，如使用近场通信的非接触支付等方面，已经宣布、展示和演示了新的进展。让我们从NFC的发展开始。

　　第一手的经验

　　在巴塞罗那的与会者能够体验NFC第一手，开始在会议入口处专用NFC徽章车道。此外，对于拥有NFC功能手机的与会者，该活动在移动世界大会会场和巴塞罗那市展示了一系列集成的移动NFC服务。第一次，NFC触摸点被放置在整个展览层，使它很容易获得信息，以及各种参展商提供和重要的下载。

　　Semiconductor manufacturers participated in the NFC showcase by trotting out their latest components. NXP Semiconductors， for example， demonstrated its NFC solutions for office， home， retail， and smart city environments. One of these solutions is what the company calls MIFARE4MOBILE， which is an advanced mobile ticketing solution that allows NFC-enabled phones to be used for contactless ticketing applications on more than 650 transport systems around the world， via the company’s MIFARE technology. Digi-Key offers a variety of MIFARE products on its website such as the PN544 NXP NFC controller featuring simultaneous multi-card management （ISO14443-A，B，B’， MIFARE） for mobile phones and portable equipment. The controller complies with all released NFC and ETSI/SCP SWP and HCI standards， guarantees interoperability with existing infrastructure， and provides a flexible platform for meeting GSMA requirements in next-generation NFC-enabled devices and services. It also offers fully-host-controllable power states， delivers a small footprint of 4.5 x 4.5 x 0.8 mm， and supports multiple secure elements.
