TP-LINK TL-SG1008P 4-Port Gigabit PoE Switch

In my previous post, I talked about the TL-SG1008PE, an 8-port Gigabit POE switch. If you need a cheaper alternative, take a look at the TP-LINK TL-SG1008P 4-Port Gigabit PoE Switch. It essentially the same switch, but it only has 4 POE ports instead of 8. It will support IEEE 802.3af compliant powered devices. Notice it’s 802.3af only. It doesn’t support 802.3at. This PoE switch currently sells for $80 at Amazon.

If you’re looking for a POE switch to power your networking devices over power over ethernet, check out the TP-LINK TL-SG1008PE 8-Port Gigabit PoE Switch. It has 8 Gigabit POE ports. It will support devices that are compliant to IEEE 802.3at/af standard. The switch has a maximum output of 124 watts. Most of all, it works quite well with the Ubiquiti Unifi products, in particular, the Unifi Outdoor Plus. The TP-Link switch currently sells for $130 at Amazon.



14 Cities With Google Fiber

Google plans to roll out Google Fiber to 14 cities. 12 cities in Kansas and Missouri have already struck a deal. Provo, Utah and Austin, Texas were recently added to the list. Google Fiber is officially available in Kansas City, MO and Kansas City, KS. Google Fiber boasts download speeds of up to 1 Gbps. Eventually, Google plans to install Google Fiber in 1000 cities. So, 2 cities down and 998 more to go.

Here’s a list of the Fiber Cities so far.

Marvell 8864 Gigabit Wireless

Marvell, the maker of wireless chips, plans to release the 8864 chip for the wireless 802.11ac Wi-Fi standard, which is capable of up reaching gigabit speeds. The release is scheduled for some time next year. Excerpt from Computerworld:

The Marvell 8864 chipset increases performance by using four antennas to receive and four to send data, a configuration which is referred to as simply 4×4. Sending and receiving data using multiple antennas is possible thanks to a technology called MIMO (Multiple-Input Multiple-Output), which is already used in both Wi-Fi and LTE networks.

In addition to MIMO, Marvell’s chipset also uses a technology called beamforming, which improves performance by aiming the signal at the receiver. The way Marvell has implemented beamforming means smartphones, tablets and laptops don’t have to proactively support it to get the advantages.

The combination of multiple antennas with beamforming results in higher speeds, as well improved range and reliability. For users the improvements also mean longer battery life, because devices such as smartphones can “get on and off the air” faster, Giordano said.

To take full advantage of the 8864 chipset’s capabilities, clients also have to have a 4×4 antenna configuration, but other clients will also see significant improvements, Giordano said.

The Marvell chipset will be used on a multitude of different products, including access points, routers, gateways, video bridges and set top boxes, the first of which will start shipping in the middle of next year.
