What are the Difference Between Indoor WiFi Router and Outdoor CPE
Indoor CPE's (Access Point, Range Extenders, Repeaters) using Omni directional antenna to transmit and receive data from all directions to improve data throughput rate and parallelly transmit data to multiple devices.
Because indoor environment has multiple radio reflections due to walls, metals, and other obstacles. This leads to multi-path for radio propagation.
So, your mobile may be receiving data from multiple paths reflected radio streams. MIMO systems are designed to understand & identify multiple-paths and transmit different Data in different Propagation Path. That’s how they maximize the Data throughput.
Indoor CPE devices have average to low antenna gain (5 to 7 dBi). Antenna gain is applicable to receiver side. It is a measure of receiver sensitivity.
Antenna receiver sensitivity means How much power it can grab from atmosphere and narrow it down to a fine cable.
Just to make it clear dBi doesn’t boost the power. For higher antenna gain the antenna size is bigger.
Indoor Routers have simple dipole antenna's whereas outdoor CPE routers have
1. Antenna arrays
2. Disc antenna
3. Parabolic Antennas.
Outdoor CPE Devices have Higher Gain Antenna (9-23 dBi). So, if you Want an Outdoor Range extender with Omni directional Antenna. A Gain of 10dBi-15dBi should do a good job.
One other way that these devices are useful is that you can send wireless signals from one Wi-Fi router to another. This means that a guesthouse can have the same Wi-Fi signal as your main house.
Outdoor CPE devices are becoming common for businesses as well as outdoor household usage. With the increasing technological advancements, many companies and products have flooded the marketplace.
