| EnGenius ECB-3220 Next Generation High Power Access Point/Bridge Review
|
 |
by Bob Ehlers
We received the first early shipments of the new ECB-3220 802.11b/g access point. This product has some impressive specifications and we were very anxious to prove that it was ready to be sold and stable for deployment. The ECB-3220 is the successor to the EL-3054CB3+ and also shares internal componentry and firmware with the soon to be released EOC-3220 outdoor access point/bridge. The key features that set the ECB-3220 apart from other access points/bridges on the market are its transmit power of 26dBm or 400mW, it's receive sensitivity of -95dB, security support for WPA (Wireless Protected Access) and WPA2, support for WMM (Wireless Multi Media) quality of service management, and SNMP (simple network management protocol) manageability.
With the arrival of this new powerhouse, enterprises, service providers and consumers should be able to greatly extend their range of coverage without the need for repeaters or adding additional access points for coverage. The receive senstivity of this unit allows it to "hear" weak client computers at distances far greater than anything else on the market, while the transmit gain allows the unit to be "heard" by clients that may not have very good receive sensitivity. Combine this with improved security which protects your network from hackers and we should have a really great solution. But do we? Read More...

| Non Line Of Sight Wireless Using 900Mhz
|
 |
With the availability of the HR-WRAPDX-9 and HR-IXP-SXP-9 products, which both support 900Mhz broadband operation, Non Line of Sight broadband becomes possible. But what are the realities?
900Mhz operation is achieved through the down-conversion of OFDM (Orthogonal Frequency Division Multiplexing) 802.11g 2.4 GHz signals from the Atheros AR5004 chipset to 900MHz. The second stage amplifier/down-converter maintains full bandwidth and amplifies the transmit signal to 28dBm or 631mW. The radio module appears to our HauteRouterOS operating system as a 2.4GHz radio. In the HauteRouterOSng operating system, we have corrected this so that our management interface shows true values for the radio.

Question: "Given all the options for operating frequencies of the HauteSpot Networks products, which one should I choose for my application?"
Answer:"It depends..." Obviously, if you are trying to offer public access "hot spot" services, then you need to stick with 2.4GHz IEEE 802.11b/g. But if you are trying to link two buildings together, create a backhaul network, operate a private network, or deliver WISP services, then 900MHz and 5GHz are certainly options. Read More... |
