The other is Frequency Range 2 (FR2), [2] which includes frequency bands from 24.25 GHz to 71.0 GHz. In November and December 2023, a third band, Frequency Range 3 (FR3), [ 3 ] covering frequencies from 7.125 GHz to 24.25 GHz, was proposed by the World Radio Conference ; as of September 2024, this band has not been added to the official standard.

The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz).Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication.
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
This level of service is the most widely deployed, and was deployed in many metropolitan areas in 2020. Some regions are not implementing the low band, making Mid-band the minimum service level. High-band 5G uses frequencies of 24–47 GHz, near the bottom of the millimeter wave band, although higher frequencies may be used in the future.
(Generally speaking, lower frequencies allow carriers to provide coverage over a larger area, while higher frequencies allow carriers to provide service to more customers in a smaller area.) In the U.S., the analog AMPS standard that used the cellular band (800 MHz) was replaced by a number of digital systems.
A mobile phone signal (also known as reception and service) is the signal strength (measured in dBm) received by a mobile phone from a cellular network (on the downlink). Depending on various factors, such as proximity to a tower , any obstructions such as buildings or trees, etc. this signal strength will vary.
Globe offers commercial wireless services through its 2G, 3G, 3.5G HSPA+, 4G LTE, and LTE-A networks, with 5G currently being deployed in key areas in the Philippines. [8] Its 5G coverage is available in over 3,000 locations all over the country, and nearly 100% of the population in the National Capital Region, Davao City, and Cebu. [9] [10]
