Philips has released a complete Unlicensed Mobile Access (UMA) semiconductor reference design to make it easy for mobile handset manufacturers to bring UMA-enabled phones to their customers.
The reference design creates a blueprint for a mobile phone that accesses GSM and GPRS mobile services through traditional cellular networks to automatically switch over to WLAN access points.
The company is working closely with Alcatel, a leading provider of communications solutions, on interoperability tests between UMA handsets based on the Philips Nexperia UMA reference design and the Alcatel 5020 Spatial Atrium mobile call server/softswitch.
Philips claims the reference design features the industry’s lowest-power 802.11g WLAN system-in-package (SiP) for connections to WLAN access points.
“The low-power characteristics of this semiconductor solution are extremely important to mobile phone applications, where customers do not want to have their talk-time jeopardised by other power-hungry applications,” the company says in a statement.
The Nexperia 6120 System Solution supports a wide variety of multimedia applications and includes a GSM/GPRS/EDGE mobile platform, an RF baseband transceiver, a power amplifier, a power management unit and a battery charger.
Philips is using Kineto’s UMA Client Software to the reference design to give mobile phones the ability to roam between mobile networks and WLANs. According to the company, the 802.11g SiP enables mobile phone users to access voice, data and multimedia services through WLAN networks up to five times faster than current 802.11b products, without compromising the battery life of mobile phones.
