Xiaomi Redmi Note 8 Pro 128Gb+6Gb Dual LTE [100/132] Minimum network capability

reader/writer role, they:

[C-4-1] MUST implement the corresponding Android APIs as documented by the Android

SDK.

[C-4-2] MUST report the feature com.nxp.mifare from the

android.content.pm.PackageManager.hasSystemFeature () method. Note that this is not a standard

Android feature and as such does not appear as a constant in the

android.content.pm.PackageManager class.

7.4.5. Minimum Network Capability

Device implementations:

[C-0-1] MUST include support for one or more forms of data networking. Specifically,

device implementations MUST include support for at least one data standard capable of

200 Kbit/sec or greater. Examples of technologies that satisfy this requirement include

EDGE, HSPA, EV-DO, 802.11g, Ethernet and Bluetooth PAN.

SHOULD also include support for at least one common wireless data standard, such as

802.11 (Wi-Fi), when a physical networking standard (such as Ethernet) is the primary

data connection.

MAY implement more than one form of data connectivity.

[C-0-2] MUST include an IPv6 networking stack and support IPv6 communication using

the managed APIs, such as java.net.Socket and java.net.URLConnection , as well as the native

APIs, such as AF_INET6 sockets.

[C-0-3] MUST enable IPv6 by default.

MUST ensure that IPv6 communication is as reliable as IPv4, for example:

[C-0-4] MUST maintain IPv6 connectivity in doze mode.

[C-0-5] Rate-limiting MUST NOT cause the device to lose IPv6 connectivity on

any IPv6-compliant network that uses RA lifetimes of at least 180 seconds.

[C-0-6] MUST provide third-party applications with direct IPv6 connectivity to the network

when connected to an IPv6 network, without any form of address or port translation

happening locally on the device. Both managed APIs such as Socket#getLocalAddress or

Socket#getLocalPort ) and NDK APIs such as getsockname() or IPV6_PKTINFO MUST return the

IP address and port that is actually used to send and receive packets on the network.

The required level of IPv6 support depends on the network type, as shown in the following

requirements.

If device implementations support Wi-Fi, they:

[C-1-1] MUST support dual-stack and IPv6-only operation on Wi-Fi.

If device implementations support Ethernet, they:

[C-2-1] MUST support dual-stack operation on Ethernet.

If device implementations support Cellular data, they:

SHOULD support IPv6 operation (IPv6-only and possibly dual-stack) on cellular.

If device implementations support more than one network type (e.g., Wi-Fi and cellular data), they:

[C-3-1] MUST simultaneously meet the above requirements on each network when the

device is simultaneously connected to more than one network type.
