3.5GHz May Be the 5G Frequency Band

The development of the next mobile communication standard 5G is progressing. Now it becomes clear that the frequency range of around 3.5 gigahertz will be the basis for 5G mobile networks worldwide. Confirmed Eros Spadotto from Canadian provider TELUS at the Huawei Global Mobile Broadband Forum in London. Even the network outfitter Huawei pleads for this frequency range in a position paper, summarizes it at 3.3 to 4.2 GHz but something further. Frequency spectrum in the range between 3.4 GHz and 3.8 GHz will be awarded in 2018 in many European countries, including a corresponding frequency auction is planned in Germany. In Canada, according to TELUS, an auction is expected in 2019.  




5G Network Frequency: 3.5 GHz to start

The frequency range around 3.5 GHz will be available worldwide in many countries for mobile phone use. However, the area is not exactly defined yet, in most countries preparations are currently underway for the allocation of frequencies to the mobile network operators and the exact "limits" of the auctioned radio spectrum are not yet known. Huawei speaks in its position paper from the C-band, more specifically between 3.3 to 4.2 and 4.4 to 5.0 GHz. In order to expand 5G networks in a timely manner, the core range between 3.3 and 3.8 gigahertz is important, according to Huawei, and should be made available to network providers as quickly as possible.   Some carriers in Europe uses the frequency range of 3.7 GHz in its 5G test network in Berlin, where it reaches speeds of 2 GBit/s, and the range is around 400 meters. The network provider expects the launch of the first 5G networks in exactly this frequency range, more specifically between 3.5 GHz and 3.9 GHz .




5G: more frequency ranges later

Although the range around 3.5 GHz will probably be used in many countries worldwide as a "base band" for 5G: significantly more radio spectrum is needed to achieve the need for bandwidth on the one hand and very good network coverage on the other. Huawei proposes three different "layers" in its position paper: the 3.5 GHz band should be sufficient as a "coverage and capacity layer" for most applications. On the other hand, very high speeds will demand significantly more radio spectrum, which will then be made available in the "Super Data Laye " - probably in the cmWave range around 28 gigahertz. Bruno Jacobfeuerborn, head of technology at Germany Telekom, assumes that at the start of 5G in the year 2020, this "super data layer" is not available, but only later expanded.  


The third very important part in the 5G frequency spectrum is the so-called "Coverage Layer". So the area with which a huge network coverage can be achieved. It does not depend on extremely high data rates, but on the fact that a basic supply of 5G can be made available almost everywhere. Huawei proposes in its position paper for the "Coverage Layer" the frequency range below 2 GHz, which is currently used by GSM, UMTS and LTE. It is conceivable, therefore, that the network operators integrated the existing LTE networks into their 5G networks, making LTE an integral part of 5G. According to Eros Spadotto, the Canadian provider TELUS assumes that the frequency range around 600 MHz will be used in North America for the "Coverage Layer" of 5G. In Europe, the area around 700 MHz is more likely to be used for this purpose.


Huawei B529s-23a HomeNet Box Test

In mid September, T-Mobile unveiled its new LTE home internet service. The internet service comes with a new upgraded offer. The Huawei B529s-23a Cube (T-mobile named it HomeNet Box ), and we are now focusing on this device.



The Huawei B529s-23a is a new LTE router that is exclusively available on T-Mobile networks. The router is easy to use and does not require any additional installation. The user will get it with a SIM card inserted without a PIN code and the whole thing will be ready to use when you return home. Let's start with Huawei B529s-23a router  specification :

  • Dimensions: 120 × 120 × 127 mm, weight: 672g
  • Frequency bands EDGE / GPRS / GSM: 2/3/5/8 (1900/1800/850/900 MHz)
  • 3G / HSPA / DC-HSPA+ frequency bands: 1/8 (2100/900 MHz)
  • LTE frequency bands: 1/3/7/8/20/32/38 (FDD: 2100/1800/2600/900/800/1500 MHz, TDD: 2600 MHz)
  • Speeds: DC-HSPA+: 42 / 5.76 Mbps, LTE cat.6: 300/50 Mbps
  • WLAN: 802.11a/b/g/n/ac (Dual Band 2.4/5 GHz)
  • External Antenna Connections: Two TS-9 ports
  • LAN / WAN connection (RJ45)
  • Slot for microSIM card
  • Built-in lithium-ion battery: 3000 mAh
  • Dedicated power supply: DC 12V / 2A
  • Support: DHCP Server, DNS RELAY and NAT, along with security services
  • The router supports up to 64 devices



The appearance of the Huawei B529s-23a router is pleasing to the eye. Cube-shaped body with rounded edges, made of black plastic with a matte surface. It looks like the predecessor router Huawei E5170 LTE Cube. The accent is horizontal, through the middle of the belt in magenta. As it turns out, it is a glowing item, but luckily the backlight can be turned off with a button. In addition to the button mentioned above, the front panel and the four status LEDs, mode, LAN, Wi-Fi, power, are also included on the front panel. On the rear panel is a power connector, LAN/WAN port, antenna connectors, and WPS button (for automatically configuring Wi-Fi connections). The bottom of the "box" is the SIM card connector and the reset button. In addition, there is a label with predefined Wi-Fi network names and passwords.



As I mentioned, after being removed from the cardboard, the HomeNet Box B529 should be ready for operation. All accustomed to chargers with microUSB connector may be surprised, because there is a power adapter with a different connector, giving the output of 12V and 2A. It was probably easier and cheaper, especially since it was rather stationary. But as if you were going to take him away from home, it's the first of the popular chargers you will not use.



When connected to the power and start up, the user can use the provided password to connect to the wireless network and use the Internet. There will be two networks: one in the 2.4 GHz band and the other in the 5 GHz band. The name scheme is: WLAN1-JYABAG WLAN1-5G-JYABAG And that "-5G-" means a 5 GHz band, which is currently less used and less disturbed. Therefore, it is worth choosing.  


We join and enjoy the benefits of the Internet and for many users it is enough to get the best possible coverage of a fast LTE network. In addition, the router provides the possibility to connect two external antennas. If you use the Huawei B529 Router at the location with weak signal, you can use LTE external antenna to get better surfing experience.



The Huawei B529s-23a is a device that offers far more capabilities than simple LTE modems. The first function is that the RJ45 port can works in both LAN and WAN mode, which means users can connect an Ethernet cable to the router and get wireless network from network provider. There is one SIM card slot in the Huawei B529s-23 router, user can insert a valid SIM card with data plan into the router and get wireless internet from the mobile network carriers. The two connection option makes users choose the data plan which suit best.  


What’s more, the built-in battery with a capacity of 3000 mAh can provides about 1 hour of working time. This is not too much, but it is a protection against momentary power shortages and is a continuation of our backup communications. And user can take it outdoor and keep it working on the go.   User can connect to the Huawei B529 router via the Huawei HiLink application, which gives you access to basic information. After logging in, you can check your connection status, the number of transferred data in the set billing period, and the connected devices. What is important for many people is to read and send text messages. You can also change settings for operator selection and preferred network type, eg "4G only".  


However, access to the settings will only be possible after you log in to the administration panel. To get there, connect to a web browser with To log in, users nee to use the standard login and password: admin / admin (we recommend to change immediately). When logged in to the panel, you will see basic connection information and device status. The next three menu items, Statistics, SMS and Update are also in the application. On the Settings tab, the most important options are grouped into eight items in the side menu. I will discuss them briefly in turn.  


Quick Setup


Allows you to change the wireless network ID and password and to enable automatic updating of the device.  


Connection settings


In this menu, you can set new APN access point profiles (default is already defined), select cellular mode (auto, only 2G, 3G only, LTE only) or network search mode (automatic / manual). We will also be able to disable data transfer or enable roaming data. However, there is no separate option for domestic roaming.  




This is a menu in which, apart from the connection status, the RJ45 network interface mode can be set. Here we will determine whether the port works as a LAN or WAN, with additional parameters. In addition, there is also a MAC clone option - the hardware address of the network adapter.    




VPN is a private network based on public links. Properly configured ensures confidentiality and communication security. Options built into the router allow you to establish a connection using the L2TP protocol. This menu will be used by more advanced users.  



Unlike the previous position, this should be used by almost every user. Wireless networks can operate both in the 2.4 GHz and 5 GHz bands, and for each band you can select the channel and bandwidth (defaults to automatic mode). Interestingly, for each band you can run two SSIDs, which gives you four visible networks. However, we will not find any additional options for separating users connecting to the router. Additional options are available for MAC address filtering and WPS settings to help you connect new devices to your wireless network. How do networks work in practice? Very good. The received network signal is stronger than the one that is offered by me, eg Horizon router from UPC. It is also slightly better compared to my second Asus RT-N16 router, which the manufacturer has armed with 3 external antennas.  




DHCP is a protocol for assigning network settings (including IP address) to the device connected to the router.  



It’s extremely powerful option that allows you to make changes to the default firewall settings. You can also block and filter devices, filter domains, and run port forwarding. DDNS (Dynamic Domain Name) is also available, but profiles are available for only three defined service providers. Interestingly, this group also includes the option to enable or disable the PIN code on the SIM card.    


In this position you can check the status of the device, perform network diagnostics, change system settings and password, or restore factory settings. At this point you will need to make changes when you connect the external antenna to the router.    




The Huawei B529s-23a router has been proven to be very powerful for home users. Good performance, connectivity, good hardware and a decent enough (for such hardware) software functionality is the most important of its advantages. And the stability and strength of the wireless network proves to be good. The built-in rechargeable battery can be used as a mobile WiFi router.


Huawei B715 LTE Cat.9 WiFi Router Released

As a direct successor to the popular LTE Router Huawei E5186, Huawei presents a new LTE router B715 in Poland for the network provider “Play”. As a new LTE advanced router, the Huawei B715 reaches LTE category 9 with up to 450 Mbit/s in the downlink, which is a great improvement than the predecessor Huawei E5186 router. The B715 router has four RJ45 Gigabit LAN interfaces and a USB port, as well as an integrated telephone function with RJ11 connection. And we also see it’s available in Latvia for network carrier LMT with branded version.

Huawei B715: 4.5G LTE Advanced Technology


The Huawei B715 has integrated LTE antennas, but also has two SMA connectors on the back for an external LTE antenna, which can be connected when needed. The LTE modem can connect up to three frequency ranges by means of carrier aggregation (channel bundling), which theoretically allows up to 450 Mbit/s in the downlink. In the uplink, up to 50 Mbps are possible via LTE. In addition to LTE, UMTS (3G) and GSM (2G) are also supported.


Huawei B715 B715c-23c


The RJ11 connector on the back panel of the Huawei B715 can be used to connect an analogue telephone, as well as a USB port for integrating a printer or storage media into the network. Wired devices can be connected via the four LAN ports. If required, one of the four LAN ports also acts as a WAN port, so the B715 can also be used with an external modem (eg fiber optic or cable modem). Wireless devices can connect to the Huawei B715s-23c via Wi-Fi, the router supports the frequency ranges around 2.4 GHz and 5 GHz.

Huawei B715 and B618 in comparison


Attentive readers may already have noticed, with up to 450 Mbps, the new B715 LTE router is not the fastest router model in the Huawei product range. The Huawei B618 even offers up to 600 Mbps via LTE Cat11. The Huawei B618 also has the 4 × 4 MIMO antenna technology installed, the B715 can seem only on 2 × 2 MIMO antenna technology fall back. Nevertheless, the Huawei B715 also has advantages over the B618: there are four RJ45 Gigabit LAN ports and not like the B618 with only 2 TS-9 connectors, the B715 has the SMA ports for external antenna, which is common on Huawei LTE stationary routers. If you need the external antenna for Huawei B715 Router, we would like to recommend below the two antennas. We had tested the antennas and they can work well with Huawei B715 LTE Router:


4G LTE Indoor Antenna (2 x SMA Connectors) for Huawei/ZTE 4G LTE Routers/Gateway/LTE CPE


If you prefer 4G outdoor antenna to get better signal, you could try below the antenna:


4G LTE Outdoor Antenna (2 x SMA Connectors) for Huawei/ZTE 4G LTE Routers/Gateway/LTE CPE


We would take full detail test for the new Huawei B715s-23c router, and compare it with the more advanced Huawei B618. Keep follow on us(twitter: 4GLTEMALL) and we will update our test report once it’s done.
