新的和顯著的移動世界大會射頻工程師的發展

　　在整個為期四天的2013世界移動通信大會（MWC）的證據是大量的在巴塞羅那，西班牙，全世界的無線移動生態系統的不斷擴大而擱置。在移動設備、產品集成電路和無線技術，如使用近場通信的非接觸支付等方面，已經宣布、展示和演示了新的進展。讓我們從NFC的發展開始。

　　第一手的經驗

　　在巴塞羅那的與會者能夠體驗NFC第一手，開始在會議入口處專用NFC徽章車道。此外，對于擁有NFC功能手機的與會者，該活動在移動世界大會會場和巴塞羅那市展示了一系列集成的移動NFC服務。第一次，NFC觸摸點被放置在整個展覽層，使它很容易獲得信息，以及各種參展商提供和重要的下載。

　　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.
