Introduction:
Netgear is an established brand in the networking world. You can’t go to any retail outlet that sales networking equipment and not find at least a router or NIC. Netgear has continuously targeted the entry-level and mid-level networking market. The networking world is an ever evolving mesh of hardware and standards that are consistently trying to one-up one another and are continuously fighting for market share. This is the case with the newest line of products being offered from manufacturers. While 802.11n is still technically not an official standard it is quickly being offered to the public by most manufacturers. Even enterprise level companies like Cisco are starting to offer products featuring 802.11n standardization.
“802.11n builds on previous 802.11 standards by adding multiple-input multiple-output (MIMO). MIMO uses multiple transmitter and receiver antennas to improve the system performance. The transmitter and receiver use pre-coding and post-coding techniques, respectively, to achieve the capacity of a MIMO link. Pre-coding includes spatial beam forming and spatial coding, where spatial beam forming improves the received signal quality at the decoding stage. Spatial coding can increase data throughput via spatial multiplexing and increase range by exploiting the spatial diversity, through techniques such as Alamouti coding. The number of antennas relates to the number of simultaneous streams: two receivers and two transmitters (2x2) or four receivers and four transmitters (4x4). The standards requirement is a 2x2 with a maximum two streams, but allows 4x4.” ~Wikipedia.org
Like every other well built computer architecture out there, the new 802.11n protocol is going to be the standard from here on out. While the standard is not official as of yet, over seventy manufacturers are already offering Wireless N (Draft 2.0) products to consumers!
In June of 2007, the Wi-Fi Alliance awarded Netgear Wi-Fi Certified under the 802.11n Draft 2.0 specifications. “We designed our RangeMax NEXT Wireless-N products to enable our customers to enjoy increased range and performance for a multitude of next-generation applications such as high-definition video streaming, online gaming, IP telephony and fast file transfers of music, photos, etc. Having been through this intensive testing process for interoperability and compatibility with IEEE draft 2.0, our RangeMax NEXT Wireless-N Routers are proven industry leaders, products that maximize the digital home experience for our global customers. By being among the first to hit this impressive mark demonstrates our unwavering commitment to driving multi-vendor interoperability.” ~Netgear.com
Enough gib-gab, let’s get to looking at the newest Wireless N products from Netgear!
