The two are very similar except that the remote unit of the former is powered by PCs or credit card terminals thru its USB cable and the latter is powered by a separate power adapter. Also, the Cordless Link for Credit Card terminals is designed specifically for credit card terminals so that it may not function as well as a Wireless Link for PC or laptop applications in some very rare occasions (less than 1% of time).
No, As a matter of fact, you can share one telephone line for as many as 10 units of Cordless Link for Credit Card terminals. However, when one of the links is in use, all others will get a busy dial tone. It’s just like sharing multiple telephones with a single phone line.
A Wi-Fi router is a gateway. It usually detects (or receives) signals from any adapter around it and routes the signal to another adapter or another router, where it enters the “cyber space”. Not only that, a router also processes the data it receives. It does encryption and decryption. A Wi-Fi adapter also processes the data. It processes the data into a “package” form and then adds a header, which tells the router where the signal will go to. It also does encryption and decryption on the data.
Our device, on the other hand, is not a gateway. It does not direct the signal to go anywhere except to the credit card processor’s gateway. It does not have any choice. It does not receive many signals. It receives only one signal from its companion device. Nor does it do anything to the signal. It does not package the data, nor does it do any encryption or decryption. It does purely transmission. It does not process the data nor does it store any data. Ours is more like a printer than a router.
The only thing it does, if you want to find a needle in the hay, is that it monitors the communication. It makes sure it is talking to a friend rather than a foe. If it is not talking to a friend, it cuts off and switches to another frequency instantly, as dictated by FCC Part 68. Most other electronic devices are certified only under Part 15. Ours is certified under FCC Parts 15 and 68.
Similar to Wi-Fi, you need to use a certified terminal. Our device does not store any data nor will it process any data, therefore it does not have security issue except for the interception of the data during the transmission process. However, legally it is impossible to “sniff” the transmission data as FCC Part 68 dictates that any two devices operate in this band cannot share the same frequency. In addition, our device does use the patent-protected Lock-In™ technology which makes it practically impossible to sniff the transmission signal.
It's the same as a cordless phone. It should reach about 200 to 300 ft in most homes and stores. It reaches further than 802.11 or Wi-Fi. It is possible to reach longer disctance if special arrangements are made. Please contact the company for more info about this.
Yes. The Cordless Link works with all operating systems. If you can currently log into with a direct wire connection, you can use the Cordless Link. No driver installation or other software changes are necessary.
The Cordless Link works without adjustment with all present and historical credit card terminals, including everything from using 300 bps Hayes products to those based on V.34, V.32bis, V.32, V.22bis, V.22, V.90/92 modem protocols. Also, no adjustment is required to move the Wireless Link from connection to a hardware-based modem on an MS-DOS machine to a software-based modem.
Microwave ovens and many cordless phones operate at frequencies higher than the 900 MHz frequency used by the Cordless Link, which therefore is not sensitive to them. Other 900 MHz devices, such as some cordless phones or a second Cordless Link, should be kept three feet away in order to avoid interference. Just as cordless phones do, the Cordless Link minimizes this problem by automatically shifting communication frequency.
The Cordless Link works at least as well as WiFi in difficult environments. Indeed, you may find that the Cordless Link works perfectly well for you in environments in which WiFi fails. The Cordless Link's microwave radio is narrow-deviation FM (frequency modulated) and operates at 900 MHz rather than at a higher frequency. Narrow deviation concentrates the Cordless Link's power for better signal-to-noise ratio. FM, as opposed to AM, rejects variations in signal amplitude (as you may have noticed in switching between noisy AM and quiet FM signals on your car radio). As explained above, the 900 MHz band is immune to several potential interference sources. And finally, the relatively long wavelength of the Cordless Link's 900 MHz signals allows them to diffract around many obstacles, thus providing more uniform coverage.
Please email a description of the problem to Nebo Wireless (support at nebowireless.com). We are happy to give you a quote, though the cost of repairing and shipping is generally more than the price of a new Cordless Link set.
