Mobile devices use wireless protocols to communicate wirelessly to an RF system. Any wireless protocol may be used to communicate by the mobile device. For example, Wi-Fi, wireless local area network (WLAN), global system for mobile communications (GSM), long-term evolution (LTE), code-division multiple access (CDMA), time-division multiple access (TDMA), evolution-data optimized (EVDO), high speed packet access (HSPA), universal mobile telecommunications system (UMTS), WiMax, and the like It would be understood that the list of wireless protocols is not exhaustive and that any other wireless protocol may be used. It would also be understood that different generations and/or versions of a protocol may be used. For example, anyone of the various generations and/or versions of LTE such as private LTE, LTE Advanced and LTE-lite. The mobile device communicates with the RF system <NUM> by way of the RF assembly <NUM>, <NUM>, <NUM>, <NUM>. The communication protocol between the mobile device and the RF assembly may be different for each technology. Within the same technology, the communication protocol may be different according to a version of the protocol. For example, different versions of the protocol may be employed by different network carriers. Each of the RF assemblies <NUM>, <NUM><NUM>, <NUM> connected to a base unit <NUM> may communicate wirelessly via different protocols.

The base unit <NUM> is any device that connects to the network <NUM> whereby the mobile devices are connected to the network by way of the base unit <NUM>. The base unit <NUM> is, for example, is a Wi-Fi access point or an edge router.

During operation, the base unit <NUM> provides power to the RF assembly <NUM>, <NUM>, <NUM>, <NUM> via the bus connector <NUM>, <NUM>.

The modular RF assembly <NUM>, <NUM> receives the power from the base unit <NUM> over the first bus connector <NUM> or to the second bus connector <NUM>. The switching circuit <NUM> is switched to receive the first voltage <NUM> from the first bus connector <NUM> or the second voltage <NUM> from the second bus connector <NUM>. When the received voltage <NUM>, <NUM> is different than the operational voltage <NUM>, the received voltage may be controlled by a voltage controller <NUM> to match the operational voltage <NUM>. The switching circuit <NUM> of the modular RF assembly <NUM>, <NUM> switches between the plurality of the bus connectors <NUM>, <NUM> to provide power to the adaptive RF module <NUM>. The switching may be handled automatically by the switching circuit <NUM>. For example, the switching circuit <NUM> switches between the plurality of bus connectors <NUM>, <NUM> according to a voltage detected at one of the plurality of bus connectors <NUM>, <NUM>. The switching circuit <NUM> may be manually set and be a physical switch, e.g. a toggle, that is preset between the plurality of bus connectors to use one of the pluralities of bus connectors. Data, which is accessible to the switching circuit <NUM>, may be stored in memory indicating which of the bus connectors <NUM>, <NUM> is to provide power to the adaptive RF module <NUM> and switching circuit <NUM>.

When an internal modular RF assembly <NUM> is mounted to the base unit <NUM>, the adaptive RF module <NUM> and the base unit <NUM> are communicatively coupled by the first bus connector <NUM> and the internal bus connector <NUM>. The coupling of the first bus connector <NUM> and the internal bus connector <NUM> is maintained within the housing <NUM> of the internal modular RF assembly <NUM> and within a casing <NUM> of the base unit <NUM>. The first bus connector <NUM> and the internal bus connector <NUM> may be, for example, a universal serial bus (USB) connector or Peripheral Component Interconnect (PCI) connector. The transport medium is the respective connectors <NUM>, <NUM>, for example, USB or PCI. The communication protocol between the adaptive RF module <NUM> of the internal modular RF assembly and the base unit <NUM> may be dependent on the type of connector. The connection between the first bus connector <NUM> of the internal modular assembly and the base unit <NUM> may be made when the modular RF assembly <NUM> is mounted to the base unit <NUM>. For example, the first bus connector <NUM> and the internal bus connector <NUM> are mating connectors that engage when the modular RF assembly <NUM> is mounted to the base unit <NUM>.

During operation of the internal modular RF assembly <NUM>, the base unit <NUM> provides power to the first bus connector <NUM>. The switching circuit <NUM> is switched to receive the first voltage <NUM> from the first bus connector <NUM>. An operational voltage <NUM> is supplied to the RF unit <NUM>. The first bus connector <NUM> may receive a voltage between 3V and 12V. The first bus connector <NUM> may receive a voltage substantially between 3V and 5V. Typically, the first voltage <NUM> received over the first bus connector <NUM> is the same as or essentially the same as the operational voltage <NUM> of the RF unit <NUM>. When the received first voltage <NUM> is different than the operational voltage <NUM>, the received voltage may be controlled by a voltage controller <NUM> to match the operational voltage <NUM>.

When an external modular RF assembly <NUM> is connected externally from the base unit <NUM>, the adaptive RF module <NUM> and the base unit <NUM> are communicatively coupled by the second bus connector <NUM>. The second bus connector <NUM> is any connector that communicatively couples the adaptive RF module <NUM> to the base unit <NUM> by a wire <NUM> that is external from the housing <NUM> of the external modular RF assembly <NUM> and a casing <NUM> of the base unit <NUM>. For example, the second bus connector <NUM> may be an Ethernet connector or an optical fiber connector. The wire <NUM>, being the transport medium, may be an Ethernet cable or optical fiber cable. The communication protocol between the adaptive RF module <NUM> of the external modular RF assembly <NUM> and the base unit <NUM> may be dependent on the type of connector.

During operation of the external modular RF assembly <NUM>, the base unit <NUM> provides power to the second bus connector <NUM>. The switching circuit <NUM> is switched to receive the second voltage <NUM> from the second bus connector <NUM>. The second bus connector may receive a voltage higher than an operational voltage <NUM>. When the voltage is higher than an operational voltage <NUM>, the switching circuit <NUM> controls the voltage to reduce the voltage to the operation voltage by the voltage controller <NUM>. For example, when the second bus connector <NUM> is Ethernet a voltage from the base unit <NUM> is used to provide the supply power to the adaptive RF module over the Ethernet. Power over Ethernet (PoE) typically supplies a voltage between <NUM> and <NUM> volts. For PoE, the second bus connector <NUM> receives a voltage between <NUM> and <NUM> volts, which is greater than the operational voltage <NUM> of the RF unit <NUM>.

A conventional base unit only has a single type of bus connector, for example, an internal bus connector <NUM>. A single type bus connector, internal or external, simplifies the communication between the RF assembly <NUM>, <NUM>, <NUM>, <NUM> and the conventional base as the transport medium of the bus connector the same. With the transport medium being the same, there is a single protocol between the convention base unit and the RF device. With base unit <NUM> comprising multiple types of bus connectors, the internal bus connector <NUM> and external bus connector <NUM> there are different transport mediums. The processor <NUM> of the base unit <NUM> is configured to.

<FIG> illustrates a communications flow between a mobile device <NUM> and the network <NUM> over the system <NUM>. A packet of information <NUM> formed according to a wireless protocol may be received by an RF assembly <NUM>, <NUM>, <NUM>, <NUM> from a mobile device <NUM>. For example, the packet of information <NUM> received by RF device <NUM> is formed according to a WIFI protocol. Based on the received packet of information, the RF assembly <NUM>, <NUM>, <NUM>, <NUM> may send a packet <NUM> of information to the base unit <NUM>. The packet <NUM> of information is transported over the bus connector <NUM>, <NUM> by a protocol suitable for the respective bus connector <NUM>, <NUM> that connects to the RF device <NUM>. The base unit <NUM> receives the packet <NUM> of information according to a protocol suitable to the transport medium of the respective bus connector <NUM>, <NUM>. For example, the packet <NUM> of information is transported over an external bus connector <NUM>, such as Ethernet using a Point-to-Point Protocol (PPP). Since the packet <NUM> of information may have been transported over either the internal bus connector <NUM> or the external bus connector <NUM>, the base unit <NUM> may be configured to identify I<NUM> the transport medium on which the packet <NUM> of information was received and/or the protocol of packet <NUM> of information. After the base unit, <NUM> identifies I<NUM>, the transport medium and/or protocol, the base unit <NUM> may send a packet <NUM> of information based on the received packet <NUM> of information and the identified data I<NUM>.

A packet <NUM> of information with information for the mobile device <NUM> may be received by the base unit <NUM> from the network <NUM>. Since the RF assembly <NUM>, <NUM>, <NUM>, <NUM> in communication with the mobile device <NUM> may be connected to the base unit <NUM> by the internal bus connector <NUM> or the external bus connector <NUM>, the base unit <NUM> may be configured to identify I<NUM> the transport medium on which to send a packet <NUM> of information and/or the protocol the packet <NUM> of information to send to the RF assembly <NUM>, <NUM>, <NUM>, <NUM>. After the base unit <NUM>, identifies I<NUM>, the transport medium and/or protocol, the base unit <NUM> may send the packet <NUM> of information based on a received packet <NUM> of information and the identified data I<NUM>. Based on the packet <NUM> of information, the RF device <NUM> may send a packet <NUM> of information to the mobile device <NUM>.

Although an exemplary embodiment of the present disclosure has been described in detail, those skilled in the art will understand that various changes, substitutions, variations, connector <NUM>, <NUM> that connects to the RF device <NUM>. The base unit <NUM> receives the packet <NUM> of information according to a protocol suitable to the transport medium of the respective bus connector <NUM>, <NUM>. For example, the packet <NUM> of information is transported over an external bus connector <NUM>, such as Ethernet using a Point-to-Point Protocol (PPP). Since the packet <NUM> of information may have been transported over either the internal bus connector <NUM> or the external bus connector <NUM>, the base unit <NUM> may be configured to identify I1 the transport medium on which the packet <NUM> of information was received and/or the protocol of packet <NUM> of information. After the base unit, <NUM> identifies I1, the transport medium and/or protocol, the base unit <NUM> may send a packet <NUM> of information based on the received packet <NUM> of information and the identified data I1.

A packet <NUM> of information with information for the mobile device <NUM> may be received by the base unit <NUM> from the network <NUM>. Since the RF assembly <NUM>, <NUM>, <NUM>, <NUM> in communication with the mobile device <NUM> may be connected to the base unit <NUM> by the internal bus connector <NUM> or the external bus connector <NUM>, the base unit <NUM> may be configured to identify I2 the transport medium on which to send a packet <NUM> of information and/or the protocol the packet <NUM> of information to send to the RF assembly <NUM>, <NUM>, <NUM>, <NUM>.
