CD-R King CW300UB 300Mbps USB Dual Antenna

The CD-R King CW300UB is 300Mbps 802.11n/b/g USB wireless dual antenna. Actually it is just a clone of Comfast, Edup, Kinamax and others which is being repainted according to brand name. It is identical to the above mention if you take a look the specification including the casing and so on, except the name which is CD-R King here in the Philippines.

EDUP EP-MS1532 Ralink RT3072 Review

Well, that, as soon as possible a "bare" of this novel adapter group 4, Tx and Rx antenna switch apart without RT3072 chipset, I think that will mark a before and after in urban use wireless adapters.

The components in detail:

If first impressions are everything an adapter is outstanding, thoroughly analyzing it is not so.

A short distance and with omnidirectional antennas that brings you a very high traffic transfers, but for medium - long distance is very inefficient, unbalanced.

The reception is much more efficient than the transmission, so the AP's detected, only the closest achievable will not because it does not have sufficient transmission power is that power is wasted by bringing omnidirectional antennas.

For medium - long distances have to adopt an asymmetrical configuration of the antenna making it unattractive for these applications.

In the image on the transmission a parabolic Maquia - Chalenger with an illuminator 2Ni Dragonfly Belgrano, to reach the target at 30km, to receive just one planar, totally unbalanced.

Recommended only for short distances and high data transfers. - mandarache

Comfast Ralink RT3072 USB 300Mbps Dual Antenna

Comfast Ralink Chipset RT3072 High Power 802.11n 300Mbps USB 1000mW 6dBi Dual Antenna

One of the Best Long-distance USB WiFi Adapters for 802.11b/g/n wireless networks.You asked for STRONGER WiFi and Extended Range and here it is. Most common Wi-Fi devices have power ratings of less than 50mW (milliwatts.) Our new Wi-Fi device is 10x as strong (1000 mW.) This adapter is what the WiFi world has been waiting for. Plus it comes with TWO 6dBi antennas which provides stronger signal for single antenna. It is compatible with almost all laptops and desktop, PCs and Macs. It is perfect to travel with and weighing less than 2 ounces and measuring 3.5 x 2.5 inches in size (8.5 x 6.3cm).

Specifications:

• Provides 300Mbps transmission rates
• WPS (PBC and PIN) enabled device
• Supports Soft AP to establish a quick wireless LAN network
• 300M Wireless LAN USB Adapter, 2.4GHz, 802.11n/g/b
• MAX-Indoor :500M,Outdoor: 2000M
• 20MHz/40MHz bandwidth
• Supports Roaming technology
• Output Power 30dBm ± 1dBm/1000mA
• Supports Ad-Hoc and Infrastructure modes
• WEP 64/128, WPA/WPA2、WPA-PSK/WPA2-PSK Support
• Supports Windows 98/SE/ME,Windows 2000/XP/VISTA/ 7/CE, Linux, Mac
• Two 6dBi detachable antenna, remarkably strengthen signal power of the USB adapter

It has a stunning 1000mw output power. So if you are looking for a device to connect to an outdoor 2.4 GHz antenna, such as on a boat or an RV, this is a perfect solution.This Wireless USB Adapter gives you the flexibility to install the PC or notebook in the most convenient location available, without the cost of running network cables.Its auto-sensing capability allows high packet transfer up to 300Mbps for maximum throughput, or dynamic range shifting to lower speeds due to distance or operating limitations in an environment with a lot of electromagnetic interference.
