A radio link only works when both ends can hear each other. For n79, IDY recommends the iAN263-L5G first: it improves transmit and receive performance with PC3 while limiting added power, heat and long-term component stress.

Choose a working radio link,
not the highest EIRP alone.
IDY compares both link directions, power and thermal design, and long-term durability. PC3 with the iAN263-L5G is the first choice because it improves both directions without raising device transmit power.

Strengthens transmit only. RF output is four times PC3, increasing the design burden for power, heat and long-term durability.
WHY 1.4× / 2×
Range scales with the square root of power.
In free space, with frequency, receiver sensitivity and propagation conditions held constant, received power is inversely proportional to distance squared. The theoretical distance that maintains the same received level therefore scales with the square root of the power ratio.
THEORETICAL RANGE RATIO√ POWER RATIO=10ΔdB / 20
iAN263 gain: applies to both transmit and receive
HPUE output: applies only to transmission from the product
Range multipliers are theoretical free-space estimates based on range scaling with the square root of the power ratio. Four-times RF output compares 200mW PC3 with 800mW PC1.5; it does not mean total product input power is universally four times higher. Actual EIRP, range, power consumption, heat, durability and applicability depend on product specifications, certification, cable loss, transmit control, installation and propagation.

Values are theoretical range ratios based on the free-space propagation model. Bars are relative visual aids and are not drawn to exact scale. The iAN263-L5G improves both directions, while HPUE extends transmit reach only.
A base station may adjust downlink transmit power and radio resources to compensate for a weaker receive path at the product. This is network-side compensation, not an increase in product antenna receive gain. Its availability and extent depend on base-station capabilities, configuration, cell design, traffic, interference and regulation, and are not guaranteed.
IDY DESIGN PRINCIPLETransmit reach alone does not make a link.
Extending only the uplink is not enough if the product cannot receive the base-station signal. That is why IDY prioritizes a high-gain antenna that improves both directions.
03IDY RECOMMENDATION
Choose a high-gain antenna.PC3+iAN263-L5GChoose ahigh-gain antenna.PC3+iAN263-L5G
Optimize the antenna and placement before increasing transmit power. IDY engineers Local 5G in an order that balances radio efficiency with product longevity.
High-gain antenna first
Improve estimated transmit and receive reach by approximately 1.4× each with PC3, preserving the architecture without adding power or thermal burden.
Optimize placement and cable
Engineer antenna position, orientation, cable loss and the base-station relationship as one radio system.
IDY chooses high-gain antenna engineering
Higher transmit power increases cost and the design burden for power, heat and long-term durability while improving only one direction. IDY chooses high-gain antenna engineering to efficiently improve both directions while retaining PC3.
04IDY RF ENGINEERING
Not an antenna in isolation.
A Local 5G radio system.
IDY evaluates the product, antenna, cable, placement and radio-link conditions with the base station as one n79 system.
