Z1900 Cell Phone Signal Booster -
Frequently Asked Questions

Do I need a Z1900?

Between 10 and 25 percent of wireless subscribers have difficulty using their wireless devices in their homes or officers due to poor signal strength indoors. The Z1900 is used to improve signal for these wireless services within areas up to 2500 sq ft. The Z1900 cell phone signal booster improves the cell phone signal inside your home or office. If you rely on your wireless phone or PDA to work consistently and reliably at home or in your small office, you should consider the Z1900 product from Spotwave.

Will the Z1900 unit work with any wireless service?

The Z1900 system will work only in the PCS frequency range (1850 – 1990 MHz).

Most of the wireless phones in use today are in the PCS frequency. It does not work with the iDEN (Nextel) service or the cellular-only (824 – 896 MHz) providers. The product look up tool on the Spotwave website allows you to enter your zip code and determine if your particular service provider is supported with the product in your area. It’s that simple.

What benefits can I expect from using the Z1900 product?

You can stop suffering from dropped calls when you’re inside your home or small office.

  • Many building materials interfere with, or block, the cell phone signal. With Z1900 system, you can bring that outside cell phone signal inside – where you need it the most.
  • You can extend the battery life of your cell phone. Because the Z1900 enhances the signal, the phone uses less power to capture the cell phone signal, thus conserving the battery of the phone- ensuring longer talk times.
  • Many cell phone users are already replacing or considering replacing their landlines and using their cell phones as their only phones. Some are using their cell phone as their primary work phone. However in order to cut the chord and go completely wireless at home, you need reliable coverage. The Z1900 improves the wireless coverage so that you can use your cell phone as your only phone if you want to.
  • In addition, Z1900 enhances the following wireless applications:
    • Sending and receiving text messages
    • Instant messaging
    • Picture mail
    • Internet usage from your cell phone
    • PDA interactive messaging
    • 3G high-speed data on laptop air cards
    • Downloading software
    • Security systems backup

Why do I lose cell phone signal strength indoors?

A great outdoor signal doesn’t always mean a great indoor signal. Several factors affect wireless signals from penetrating into buildings, including building material (metal, concrete, tinted glass), wall density, the number of windows and building height.

Can I use a Z1900 product in my home?

Yes, Z1900 cell phone signal boosters can be used in both homes and businesses. Many consumers want to use their cell phone to replace an expensive landline phone, and many more need a stronger cell phone signal for their home office.

Can I use a Z1900 product in my business?

Absolutely. Even small businesses invest a great deal of money in wireless services – cell phones, PDAs, and 3G technologies - for the benefit of owners, employees and customers. In a business situation, more than anywhere, enhancing signal strength is a necessity, not a luxury because the business benefits of the wireless investment cannot be fully realized if the wireless tools you’re paying for cannot be used within your own facility.

How can I tell if it will help extend coverage in my home or office?

If you can place a call outside your home or small office, the Z1900 cell phone signal booster unit will help you by boosting the signal inside the building. Usually this can be done with one or two bars displayed on your cell phone. If there is no signal outside, this unit will not give you an improvement in coverage. Remember, we can only help improve your signal strength if you have enough of a signal outside to place a call. The Spotwave website product look up tool allows you to input your zip or postal code to determine what carriers will be supported with the product in your area.

How much will my cell phone coverage be extended with a Z1900 product?

Spotwave's Z1900 can take a relatively weak outdoor signal ( eg 2 Bars or -100dBm) then boost it and retransmit it inside the home at a full 4-5 bars on your cell phone (-85 to -80dBm).

Our Z1900 is rated to provide signal improvement to a maximum of 2,500 sq ft in a typical wood frame open home or office environment. Since every home is different, we recommend placing the coverage unit where in area (such as home office) where signal improvement is most required and then the signal will degrade as it passes through walls and floors.

What can I expect my cell phone signal range and strength to be inside my home or office?

The closer you are to the Coverage Unit, the more bars you will see on your phone. This will vary with different conditions. Some of the conditions that will affect the improved coverage area are signal strength outdoors, the type of walls in the home, the placement of the unit and proximity to cellular towers.

Your expectations should be that your indoor coverage will be improved. You will be able to make calls and use your PDAs where you couldn’t before. The coverage improvement will depend upon many factors. The intent of the Z1900 product is to bring outside coverage inside.

How does a Z1900 work?

The basic Z1900 intelligent coverage system is comprised of a Network Access Unit (NAU), a Coverage Unit (CU) and a power supply. The NAU is the outward facing part of the system that communicates with the base station or cell tower. The NAU can be installed indoors or outdoors depending on where you can locate the best signal. The NAU is connected (via coaxial cable) to the Coverage Unit which provides wireless coverage to indoor areas.

Where is the best place to put my Z1900 NAU?

The Network Access Unit is the outward facing unit. It is the unit that picks up the signal from and communicates with the service provider’s cell tower. Locating the Network Access Unit in a window, or on an exterior wall, away from metal siding and as high as possible will usually provide better performance.

Use your mobile phone to identify the inside location with the strongest received signal (usually near an exterior wall). If no adequate signal is available indoors then it may be necessary to try an outside location (such as an outside roof or external wall) where a stronger signal is received.

Where should I put my Z1900 Coverage Unit to get the best coverage?

Where you need coverage the most. The Z1900 Coverage is the component that amplifies the signal inside. The coverage is improved in a circular manner from the base unit. The farther you are away from the base unit, the weaker the signal. The CU could be placed in the family room, the basement, an office, a bedroom, a home office or a central location. The unit comes with 35ft of cable to connect the Network Access Unit to the interior CU. Should you need a longer (replacement, not addition to) cable, these can also be purchased directly from Spotwave.

The blue indicator on the bottom of the Network Access Unit is an indicator of the level of RF isolation between the Network Access Unit and the Coverage Unit. If the indicator is a solid blue, then there is enough RF isolation (between the Network Access Unit and Coverage Unit) to provide the best coverage possible. The Coverage Unit can be mounted to a wall or placed on a desk or shelf using the included cradle. If it makes cable routing easier, you can also mount the Coverage Unit upside down with the cables extending downward.

Is a Z1900 the same as a wireless router; will it help my WIFI signal?

The Z1900 will not help your WIFI service. This unit is designed to work with wireless PCS phones and devices. The WIFI in your home or office uses a different frequency.

Will the Z1900 interfere with any other wireless signals in my home?
Not only does Spotwave ensure the Z1900 will not cause interference with other wireless electronics in your home, but we use patented technology to ensure the product will not create any interference in the frequencies in which it operates or on a carriers wireless network. Spotwave products use a patented coverage area signature (CAS) technique to ensure constant stability and no interference. No other product on the market does this.

Can using the Z1900 improve the battery life of my wireless phone?
Yes! Because the Z1900 boosts the signal, the phone will consume less power to capture the cell phone signal, thus conserving the battery of the phone -- enabling you to talk longer.

Can I install a Z1900 product myself?

The Z1900 cell phone signal booster system is designed to be easy to set up. Detailed installation instructions are included with the system and available on our website.

Many vendors advertise that a product will work, but fail to deliver. Do you have any references?

Spotwave knows that some of the most critical and hardest to please consumers are technology reporters. So we’ve trench tested the product with some key product reviewers who all attest the product has worked for them. Don’t just take our word for it – see what the journalists themselves had to say after using the Z1900.
