multimedia streaming. .. panels:: :container: container pb-4 :column: col-lg-12 p-2 :card: shadow **What devices support 802.11g?** Most Wi-Fi-enabled devices manufactured after 2003 support 802.11g or later standards. .. panels:: :container: container pb-4 :column: col-lg-12 p-2 :card: shadow **Can 802.11g coexist with 802.11b devices on the same network?** Yes, but the network speed may slow down to accommodate 802.11b devices. .. panels:: :container: container pb-4 :column: col-lg-12 p-2 :card: shadow **What kind of antenna does 802.11g use?** It can use omnidirectional or directional antennas depending on the deployment. .. panels:: :container: container pb-4 :column: col-lg-12 p-2 :card: shadow **What transport protocols does 802.11g support?** 802.11g supports all IP-based transport protocols like TCP, UDP, and others over Wi-Fi. .. panels:: :container: container pb-4 :column: col-lg-12 p-2 :card: shadow **Is 802.11g affected by interference?** Yes, operating in the 2.4 GHz band makes it susceptible to interference from Bluetooth devices, microwaves, and cordless phones. .. panels:: :container: container pb-4 :column: col-lg-12 p-2 :card: shadow **Is 802.11g compatible with modern Wi-Fi routers?** Yes, most modern routers support legacy 802.11g devices, though they typically operate on newer standards by default. .. panels:: :container: container pb-4 :column: col-lg-12 p-2 :card: shadow **What is the difference between 802.11g and 802.11n?** 802.11n offers higher speeds, uses both 2.4 GHz and 5 GHz bands, and supports MIMO technology, unlike 802.11g. .. panels:: :container: container pb-4 :column: col-lg-12 p-2 :card: shadow **Does 802.11g support QoS features?** Basic QoS is supported, but advanced QoS mechanisms are part of later standards like 802.11e. .. panels:: :container: container pb-4 :column: col-lg-12 p-2 :card: shadow Topics in this section, * :ref:`Learnings in this section <802_11g_step1>` * :ref:`Terminology
