True 3G systems such as EV-DO, W-CDMA (including HSPA and HSPA+) provide combined circuit switched and packet switched data and voice services from the outset, usually at far better data rates than 2G networks with their extensions. All of these services can be used to provide combined mobile voice access and Internet access at remote locations.
WiMAX release 2.1, popularly branded as WiMAX 2+, is a backwards-compatible transition from previous WiMAX generations. It is compatible and interoperable with TD-LTE . Newer versions, still backward compatible, include WiMAX release 2.2 (2014) and WiMAX release 3 (2021, adds interoperation with 5G NR ).
Unifi Mobile operates 4G WiMAX, 4G LTE, and 4G LTE-A networks, and provide domestic roaming with Maxis with 4G and 2G EDGE networks.. In March 2007, P1 was one of four companies awarded 2.3GHz spectrum licenses by the Malaysian government to deploy 4G WiMAX services throughout Malaysia.
A 2011 update provides data rates up to 1 Gbit/s for fixed stations. WiMax offers a metropolitan area network with a signal radius of about 50 km (30 miles), far surpassing the 30-metre (100-foot) wireless range of a conventional Wi-Fi LAN. WiMAX signals also penetrate building walls much more effectively than Wi-Fi.
IEEE 802.16 - called fixed WiMAX because of static connection without handover. IEEE 802.16e - called mobile WiMAX because it allows handovers between base stations. IEEE 802.16m - advanced air interface with data rates of 100 Mbit/s mobile and 1 Gbit/s fixed.
The two-bit protocol version subfield is set to 0 for WLAN (PV0) and 1 for IEEE 802.11ah (PV1). The revision level is incremented only when there is a fundamental incompatibility between two versions of the standard. [1] [2] PV1 description is incorporated in the latest 802.11-2020 standard.
The growth of laptops and 802.11/Wi-Fi wireless networking have made MANETs a popular research topic since the mid-1990s. Many academic papers evaluate protocols and their abilities, assuming varying degrees of mobility within a bounded space, usually with all nodes within a few hops of each other.
