Broadcom Feeling Chipper About Mobile



The next wave of mobile technology is 65 nanometers in size. Broadcom’s new BCM4329 chip unifies 802.11n, enhanced data rate Bluetooth and FM radio capabilities into one tiny piece of silicon that brings mobile technology up to speed for the modern day. From traditional broadcast to wireless Internet connection, this tiny piece of technology represents yet another breakthrough for mobiles as they become more and more tied into the worlds of broadcast and online audio content delivery.

Via John Cox at Network World:

The 65-nanometer chip supports 11n in both the 2.4GHz and 5GHz bands, and can run simultaneously in both. Given the constraints of handset size and power, the chip supports only one 11n data stream and one antenna, compared with notebooks or access points that typically support two or possibly three streams, each with a corresponding antenna. The chip’s Wi-Fi performance maxes out at 50Mbps of wireless throughput, according to the vendor. That’s still nearly twice the throughput of 11a or 11g Wi-Fi.

It supports Bluetooth data rates of 1M, 2M and 3Mbps, based on the Bluetooth 2.1 specification with enhanced data rate. The chip uses Broadcom algorithms to all Bluetooth and Wi-Fi to operate at the same time in the 2.4GHz band, and to use a shared antenna system.

The three most important types of wireless connectivity are combined in one chip. Not a new concept, but the overall capabilities presented are still quite impressive. The fact that is it the first chip to allow full 802.11n compatibility should make it a leader in the market pretty quickly, barring any unforeseen issues. The improved security and enhanced speed provided by adopting the 802.11n protocol will make these very popular chips. Think about the speed that Mr. Cox speaks of above. In an era where video and audio are constantly streamed to handsets everywhere, speed is important. Even more than desktop users, the mobile market is always hungry for more throughput. Looks like they’ll have it now!

In a world where the public’s two concerns seem to be connectivity and data security, it should be the foundation for a whole new generation of phones and smart phones.
