Voyager Alpha CL-2200XP Alpha long range wireless phone station to station handset expandable 2 way radio

1. Is this a cellular phone?

No. They are regular cordless phones that are capable of giving you long-range communication. In certain applications, it can replace the use of cellular phones.

2. Is your phone Digital Spread Spectrum (DDS)?

No. Digital Spread Spectrum technology is generally used in the newer 2.4 GHz digital phones. DSS technology works by taking a phone signal and dividing it into multiple channels. The phone broadcasts its signal through all these multiple channels at the same time. There are 2 drawbacks:
a. The power from the phone is divided into multiple channels (as many as it is divided into) to supply the same amount of power to each channel. Generally, less power means less range.
b. The signal is broadcast through the multiple channels from the phone in a fan-pattern. If you try to install two phones side-by-side, the signals overlap and cause interference. DSS phones are not very good for multi-phone systems.

3. I can buy other consumer 900Mhz or 2.4GHz phone for a lot less. Why is your phone more expensive?

The Voyager phones are designed for commercial applications (though they can just as easily be used for the home). Many standard features such as Auto Voice Attendant, Digital Voice Scrambler, Digital Answering Machine, Adjustable Ringer and Speaker Volumes, and expandability to multi-line and multi-handsets are all already built-in. The main feature is its long-range capabilities. The signal from your conventional cordless phone will probably lose its signal after about 1 block. The Voyage phones should easily give you a range of at least half a mile. All Voyager phones systems can easily penetrate through 15 floors of concrete and still provide a clean signal.

4. How can I improve my range?

Installing an omni-directional roof antenna will dramatically increase the range of the phone, especially if you can install it higher than most of the surrounding buildings. A yagi antenna is designed to channel the signal in only one direction and it will give you greater distance than a standard omni-directional antenna.

5. Is your phone digital?

Yes and no. All data processing within the phone is done digitally but it sends the signal through one analog (called Narrow Band) channel. This is how Voyager phones can achieve long distances.

6. Can I connect more than one phone line into your system?

No. One base unit can accommodate only one phone line. You can have a multi-phone system by installing more base units.

7. Do I need a roof antenna?

No. It is not mandatory but it will dramatically increase the range of your phone.

8. Can I use you phone in a concrete building?

Yes. The Voyager CL-2200XP Series phones were tested and we were able to penetrate through at least 15 floors of concrete without losing any signal quality. All the other Voyager phones will give you the same performance, if not better.

9. What is the range between handset and handset and do I need to go through the base station?

Yes, you have to go through the base station and this is actually an advantage because it could double your range. Generally, phone systems that claim to have intercom between 2 handsets without the use of the base unit have very limited range.

10. Why are you using 900MHz when 2.4, 5.8 and 1.9 GHz is the latest technology?

900MHz has better penetration power. Also, 2.4GHz generally incorporates Digital Spread Spectrum technology and this causes interference when you are using a multi-phone system. Actually, microwave ovens operate on 2.4GHz so you could receive a lot of interference if you are using it at home.

11. Which phone systems are approved for use in the United States and Canada?

The CL-2200XP Series phones have both F.C.C. and D.O.C. approvals.

12. Do you use "frequency-hopping" technology to prevent eavesdropping?

No. Voyager incorporates a Digital Voice Scrambler system to prevent eavesdropping.
