  1. The main LTE bands are in bold print. Not yet deployed are not available (N/A). Partial deployments varies from country to country and the details are available at List of LTE networks . Networks on LTE bands 7, 28 (LTE-FDD) are suitable for global roaming in ITU Regions 1, 2 and 3. Networks on LTE bands 1, 3 (LTE-FDD) are suitable for roaming ...

  2. The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn ), or 1 km in 2.91 s or one mile in 4.69 s. It depends strongly on temperature as well as the medium through which a ...

  4. 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.

  5. Frequency bands for 5G New Radio (5G NR), which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), which includes sub-6 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to cover potential new spectrum offerings from 410 MHz to ...

  6. The "duck test" is meant to be used for internal processes within Wikipedia. For example, consider that " User:Example1 " is engaged in a heated dispute with someone else, and gets blocked because of it. Immediately after, a " User:Example2 " registers on Wikipedia and continues the dispute right away, saying the same things and in the same tone.

  7. The Myers–Briggs Type Indicator ( MBTI) is a pseudoscientific [5] self-report questionnaire that claims to indicate differing "psychological types" (often commonly called "personality types"). The test assigns a binary value to each of four categories: introversion or extraversion, sensing or intuition, thinking or feeling, and judging or ...

  8. The Beta function (in the denominator of the beta distribution) approaches infinity, for both parameters approaching zero, α, β → 0. Therefore, p−1 (1− p) −1 divided by the Beta function approaches a 2-point Bernoulli distribution with equal probability 1/2 at each end, at 0 and 1, and nothing in between, as α, β → 0.
