    • Small ∼ Less than 250 sq. m. ∼ 1-2 rooms
    • Medium ∼ 250 - 500 sq. m. ∼ 3-5 rooms
    • Large ∼ 500 - 1000 sq. m. ∼ Large spaces
  2. The required service
    • 2G / GSM ∼ Voice Call and SMS
    • 3G / UMTS ∼ Internet Data
    • 4G / LTE ∼ Internet Streaming
    • All services ∼ Voice Call, SMS, and Internet
  3. The subscribed carrier network
    • Vodafone NZ / Spark / 2 Degrees 


Different carrier networks run on different frequencies. It is important to get a mobile booster that supports the frequency of your carrier network.
The table below shows the 2G, 3G, and 4G frequencies supported by each carrier network:

Carrier Network \ Service 2G / GSM 3G / UMTS 4G / LTE
Vodafone NZ 900MHz 2100MHz 800/2600MHz
Spark 850MHz 850MHz 1800MHz

Other key factors

Getting the right mobile booster is vital, nevertheless, obtaining the right accessories to set off a more effective result is fundamental. You can determined whether additional accessories is required by knowing:

  1. Your location
    Users in urban areas tend to receive stronger network signal than users in rural areas. Outdoor signal input is essential for mobile boosters to function. It is crucial to get the correct antenna to ensure ample signal input into the booster.
    You can refer to the table below:
    Outdoor Signal Strength Solution
    3 -5 Signal Bars
    A standard panel antenna which is included in the kit is sufficient to provide coverage. Users in city area can get an Outdoor Omni Antenna to obtain an all-rounded reception.
    2-3 Signal Bars
    An Outdoor Yagi Antenna is recommended. A Yagi can increase outdoor signal reception by 9-11dB.
    0-2 Signal Bars
    An Outdoor Parabolic Antenna is recommended as it can collect network signals from the base station as far as up to 30km. Please note that the parabolic antenna is only allowed in rural areas.
  2. The building infrastructure
    Open-plan houses tend to receive better signal coverage than houses with multiple partition walls. Signals are weakened as they pass through walls. For buildings with multi-levels and partition walls, you may need a booster with stronger output power to enhance the indoor coverage. Alternatively, you can consider a Indoor Antenna Extension System . This system allows you to have multiple indoor whip aerial extended from the main booster unit to other areas of the building. Below table shows a list of our products that support this syatem and the maximal whip aerial each product can connect.
