DW500 Band 3 + 1 Explained: How the 500m² 20dBm Flagship Booster Delivers EE Voice, 1800MHz 4G and 2100MHz 3G All-Networks
The Boost4U DW500 is the 500 m² flagship of the DW dual-band series, pairing Band 3 at 1800 MHz with Band 1 at 2100 MHz for a large detached house, villa, multi-floor home, medium office, pub, restaurant or small hotel. Band 3 carries the EE family's voice calls and 4G LTE data for EE, BT, ASDA and Virgin handsets; Band 1 carries 3G UMTS data and voice across all four networks — EE, O2, Vodafone and Three. Inside the chassis the two stages share ≥60 dB uplink and ≥65 dB downlink gain, a ≥20 dBm flagship output and a ≤5 dB noise figure, fed by the included high-gain Yagi donor aerial and distributed to three indoor whips through the optional 3-way splitter. This deep dive explains what each frequency block carries in the UK, how the gain and output power cover a 500 m² footprint, which MVNO rides which host network, what remains covered outside the local 3G footprint, the honest gaps around rural 800 MHz 4G, legacy 2G and 5G, the Ofcom and UK conformity marks behind the install, and how the DW500 compares with the lower DW tiers and the other 500 m² band combos.
Answer first: on Band 3 (1710–1785 MHz uplink, 1805–1880 MHz downlink) the DW500 amplifies EE-hosted voice calls and 1800 MHz 4G LTE for EE, BT Mobile, ASDA Mobile, Virgin Mobile, Orange, T-Mobile and The People's Operator handsets; on Band 1 (1930–1990 MHz uplink, 2110–2180 MHz downlink) it amplifies 3G UMTS data and voice for EE, O2, Vodafone and Three and their hosted MVNOs. The ≥60/65 dB gain lifts the one to two bar donor picked up by the included Yagi, and the ≥20 dBm output spreads that recovered field through three whips across a 500 m² space for up to 50 users. Where the property sits beyond a local 3G footprint, EE-family handsets keep circuit voice on Band 3 while non-EE SIMs rely on the host's own fallback. The chassis does not tune Band 20 800 MHz rural 4G, Band 8 900 MHz legacy voice or any 5G NR layer, and it cannot help where the outside phone reads zero bars.
Band 3 at 1800 MHz: the EE-Family Voice Call and 4G Layer Across a 500m² Property
Band 3 occupies 1710–1785 MHz on the uplink, where handsets transmit, and 1805–1880 MHz on the downlink, where the mast transmits. In the UK this block carries the EE family's voice calls, texts and 4G LTE data, and it is the layer that keeps an EE, BT, ASDA, Virgin, Orange, T-Mobile or The People's Operator handset calling and browsing inside a large detached home, office, pub or hotel where the handset alone drops behind masonry, glazing or a concrete slab.
Why Band 3 carries both voice and 4G for the EE family
EE allocates its 1800 MHz spectrum across both voice circuit work and 4G packet data; a DW500 handset on an EE-family SIM therefore keeps a normal circuit voice call and a 4G data session on the same band stages, rather than hopping to a separate voice layer the repeater does not carry. For an EE household or cafe whose main account relies on reliable calls, texts and outgoing email, this Band 3 layer is the primary service: incoming and outgoing calls, texts, messaging apps and light browsing hold indoors through the main room, upper bedroom, office meeting room and bar area after the 65 dB downlink gain stages amplify the block and the 3 dBi interior whip re-radiates it through the main room and any split second or third room.
| Brand | Host | Band 3 service in the home |
|---|---|---|
| EE | EE | Voice calls, texts and 1800 MHz 4G LTE data |
| BT Mobile | EE | Voice calls, texts and 1800 MHz 4G data |
| ASDA Mobile | EE | Voice calls, texts and 1800 MHz 4G data |
| Virgin Mobile | EE | Voice calls, texts and 1800 MHz 4G data |
| Orange, T-Mobile, The People's Operator | EE legacy family | Band 3 voice call layer on legacy plans where retained |
The DW500 amplifies whatever band signals the host mast sends; one serving carrier is tuned band at a time, so a household with an EE main account and an O2 or Three secondary SIM should confirm both hosts' masts are visible through the chosen omni or Yagi position. In a shared, mixed-carrier family or small business, the EE-family members hold calls on Band 3 while everyone falls back to Band 1 3G as the common cross-network layer.
Band 1 at 2100 MHz: the 3G UMTS All-Networks Fallback
Band 1 pairs 1930–1990 MHz uplink with 2110–2180 MHz downlink. This is the 3G UMTS layer, and on the DW500 it carries data and voice across all four MNOs: EE, O2, Vodafone and Three. Its job in the property is the shared safety net: a handset on a non-EE host cannot hold its own data layer on this chassis, or the property sits outside that newer 4G footprint, the phone steps to the 3G stage the chassis still amplifies.
How 3G keeps every network's calls and data alive indoors
3G UMTS supports circuit voice and packet data; an O2, Vodafone or Three handset that cannot hold a newer 4G bearer can still call, text, send a location fix or hold a low-bandwidth data session over the amplified 2100 MHz block. For a mixed-carrier family, staff on an O2 or Vodafone SIM, a business serving customers on several networks, and a small office laptop tethered to an O2 or Vodafone mobile hotspot all depend on Band 1 redundancy that a single-band Band 3 repeater cannot provide. The chassis tunes both bands together: the main whip feeds both donors, and the three branch whips re-radiate the combined field over floors and rooms.
2100 MHz propagation inside brick, plasterboard and party walls
The 2100 MHz band travels shorter distances and loses more through thick brick, concrete, party-wall masonry, bar chrome, kitchen stainless steel and salon stations than a lower rural band would, which is why the interior whip sits central to the main usage area rather than at the far edge of the property. The ≥65 dB downlink gain recovers the faint handset-side signal back toward the mast, and the ≥20 dBm output keeps the room field audible across the main rooms; an upper bedroom or rear cafe corner that reads light on Band 1 is the reason to move that room's whip toward it or add the third branch whip, not to shift the donor mast bearing.
How ≥60/65 dB Gain and ≥20 dBm Output Cover 500m² with Three Whips
The DW500's radio numbers are sized for a five-bedroom detached home, villa, medium office, pub, restaurant or small hotel rather than a single flat; gain, output power, noise figure, included Yagi donor aerial and three-whip distribution each play a separate role in that 500 m² field.
≥60/65 dB: middle-tier gain matched to the large-property footprint
Gain is the chassis's amplification of the faint donor signal: ≥60 dB on the uplink from handset to mast, ≥65 dB on the downlink from mast to handset. That middle-tier recovery is what allows the signal to reach a second reception, upper bedroom, hallway and rear cafe corner across 250 to 500 m² rather than stopping at the main room. The 60/65 dB figures recover the one-to-two-bar donor behind glazing and masonry to a usable reading without pushing the stage into feedback inside a confined room.
≥20 dBm: flagship output that feeds three branches across the property
The ≥20 dBm figure is the field the interior whips radiate into the rooms; this is the difference between the DW500 and the lower home tiers. Compared with the DW250's ≥17 dBm, the flagship output is roughly double the radio power feeding the three-whip layout; compared with the DW200's ≥10 dBm, the 10 dB gap represents about ten times the transmitted field, which is what allows three branch whips and a 50-user load rather than two whips and twenty users. The ≤5 dB noise figure keeps the amplified field clear of hiss and noise, and automatic gain control balances the level as handsets approach and leave each whip.
| Parameter | DW500 figure | What it delivers in the property |
|---|---|---|
| Uplink gain | ≥60 dB | Weak handset call and data recovered back to the mast |
| Downlink gain | ≥65 dB | Faint donor amplified to the indoor whips across three rooms or floors |
| Output power | ≥20 dBm | Balanced field for up to 50 handsets across three splitter branches |
| Noise figure | ≤5 dB | Keeps the amplified field clear of hiss and noise |
| Users / space | 50 handsets, 500 m² | Large detached home, villa, medium office, pub, restaurant, small hotel |
| Outdoor aerial | High-gain Yagi included in the kit | Roof or mast donor pick-up aimed at the best combined mast bearing |
| Indirect hardware | 3 dBi whip, 3-way splitter option | Main whip in the central area; split whips in separate rooms, floors or annex |
The included Yagi matters at this tier because the donor for a large rural or semi-rural property often sits on a distant mast; its directional gain concentrates the receiver on that bearing and feeds a stronger combined Band 3 and Band 1 block into the chassis than a broad omni could pull at the same distance. The three-whip layout then spreads that recovered field over the wide footprint, with the main whip central and the second and third whips serving the spaces beyond concrete partitions or stairwells.
MVNO Host Map: Which Budget SIM Rides Which Host on the DW500
A household or small business using budget SIMs should know which host each brand rides; the DW500 amplifies the host's Band 3 and Band 1 layers, so a SIM's indoor service follows its leased network rather than its own brand name.
| Brand | Host | Band 3 / Band 1 position indoors |
|---|---|---|
| EE, BT Mobile, ASDA Mobile, Virgin Mobile, Orange, T-Mobile, The People's Operator | EE | Band 3 voice calls and 1800 MHz 4G plus Band 1 3G fallback |
| giffgaff | O2 | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Tesco Mobile | O2 | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Sky Mobile | O2 | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Lycamobile | O2 | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Plusnet Mobile | O2 | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Smarty | Three | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| iD Mobile | Three | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Lebara | Vodafone | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Talkmobile | Vodafone | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| FreedomPop, TalkTalk | Leased fallback host per plan | Check the SIM's current host in the handset status menu; service follows whichever host the plan leases |
Only the EE-hosted brands receive the Band 3 1800 MHz voice and 4G circuit through this chassis; O2-hosted, Three-hosted and Vodafone-hosted MVNOs rely on Band 1 3G indoors. A household mixing an EE main account with giffgaff, Smarty or Lebara members should test each SIM at the main whip before buying the splitter expansion, because a weak non-EE donor bearing limits the Band 1 fallback even where Band 3 holds well.
Voice Fallback Outside the 3G Footprint and the VoLTE Position
Which calls remain connected beyond a local 3G area
If the premises sits outside the local 3G footprint, the EE-family handsets keep circuit voice on Band 3, because that layer is tuned into the DW500 alongside the 4G data block; an EE, BT, ASDA or Virgin handset can still call and text indoors even where the surrounding area has no 3G coverage on other hosts. A non-EE family member on O2, Vodafone or Three loses its repeatable circuit fallback through this chassis, because Band 1 is the only voice layer those hosts receive here; that member relies on the host's own network fallback, which the repeater cannot create.
VoLTE: where 4G Calling applies
Where the handset and host support Voice over LTE, voice rides the 4G packet layer rather than a separate circuit channel; the DW500 amplifies the Band 3 1800 MHz layer either way, so an EE-family VoLTE call follows the same amplified block as a normal Band 3 call. If 4G Calling is switched off in the phone settings, the handset falls back to the circuit voice channel on Band 3 for the EE family. This chassis carries no legacy 2G voice band, so a handset that depends on a 2G circuit call cannot be served by the DW500 even where the host still transmits that layer locally.
DW500 vs the Lower DW Tiers and the Other 500m² Band Combos
The Boost4U range splits by tuned band and coverage tier; the DW500 is the only 500 m² flagship that pairs EE-family Band 3 voice and 4G with all-network Band 1 3G. Choosing the wrong combo leaves either the EE call layer or the shared 3G fallback unboosted.
| Model | Bands | Service boosted indoors | Position versus DW500 |
|---|---|---|---|
| DW500 | Band 3 + Band 1 | EE-family voice and 1800 MHz 4G plus all-network 3G, ≥60/65 dB, ≥20 dBm, 500 m², 50 users, three whips, Yagi included | Flagship voice-plus-3G combo for large homes and businesses |
| DW250 | Band 3 + Band 1 | Same EE voice and 4G plus all-network 3G, ≥60/65 dB, ≥17 dBm, 250 m², 25 users, three whips, omni with Yagi upgrade | Half the space and users, lower output, donor aerial as an upgrade purchase |
| DW200 | Band 3 + Band 1 | Same EE voice and 4G plus all-network 3G, ≥60/65 dB, ≥10 dBm, 200 m², 20 users, two whips | Two-room footprint and lower output for a two-bed home |
| DW100 | Band 3 + Band 1 | Same EE voice and 4G plus all-network 3G at entry tier, ≥45/50 dB, ≥10 dBm, 100 m², 10 users | Single-flat footprint and lower gain |
| CD500 | Band 20 + Band 3 | EE, O2 and Vodafone 4G data on 800 and 1800 MHz; no 3G band, no EE voice circuit | 4G data families without voice calls or 3G fallback |
| CG500 | Band 20 + Band 8 | O2/Vodafone 4G on 800 MHz plus legacy 2G voice on 900 MHz; no 3G, no EE 4G band | Rural 4G and legacy voice without the EE 4G or all-network 3G layer |
| CW500 | Band 20 + Band 1 | O2/Vodafone 4G on 800 MHz plus 3G all-networks on 2100 MHz; no EE voice band | Rural 4G data plus 3G without the EE-family voice layer |
Choose the DW500 where the priority is EE, BT, ASDA or Virgin voice calls and 1800 MHz 4G together with O2, Vodafone and Three 3G across a large property. Choose the CD500 for an EE, O2 or Vodafone 4G data household with no call band requirement; the CG500 for O2/Vodafone rural 4G plus legacy 2G voice; the CW500 for O2/Vodafone rural 4G plus all-network 3G without EE voice; the DW250 for a 250 m² property, the DW200 for a 200 m² two-room space, and the DW100 for a single flat or room.
Honest Limits: What the DW500 Does Not Tune, and the Compliance Marks Behind the Install
The bands and services this chassis cannot cover
The DW500 carries no Band 20 on 800 MHz, so it cannot amplify the rural 4G layer that EE, O2 and Vodafone broadcast at long range; a property whose only outside reading sits on that 800 MHz block should compare the CD500, CG500 or CW500 combos instead. It carries no Band 8 on 900 MHz legacy voice, so a handset relying on a 2G circuit call is not served here, and it carries no 5G NR layer of any band; 5G handsets inside the property fall back to whatever 4G or 3G the host transmits on the tuned blocks. The repeater needs at least one to two bars outside the property on the target band; it cannot manufacture a signal where the mast transmits nothing, and it cannot rescue a basement, steel barn or concrete strongroom that the tuned waves cannot reach from the main chassis.
Compliance, climate and guarantee
The DW500 is an Ofcom licence-exempt mobile repeater class device for indoor use, carrying UKCA, CE and RoHS conformity marks; the Yagi donor aerial and indoor whips must be spaced to keep the stage from feeding back onto the macro masts, which is the separation rule covered in the installation guide. The chassis operates from minus ten to plus fifty five degrees Celsius, carries a 365-day money-back guarantee and lifetime technical support, and runs on a 5V DC adapter from an AC 100–240 V 50/60 Hz UK mains supply. On a moving handover between adjacent masts, the chassis follows the donor bearing the Yagi sees; if the property sits on a soft mast boundary, re-aiming the Yagi toward the stronger combined bearing is the first check before assuming the chassis gain is at fault.
Frequently Asked Questions
The DW500 pairs which paired bands, and what voice and data service does each deliver to a 500m² villa, office or pub?
Band 3 at 1710–1785 MHz uplink and 1805–1880 MHz downlink carries EE-family voice calls, texts and 1800 MHz 4G LTE for EE, BT, ASDA, Virgin, Orange, T-Mobile and The People's Operator; Band 1 at 1930–1990 MHz uplink and 2110–2180 MHz downlink carries 3G UMTS data and voice for EE, O2, Vodafone and Three and their hosted MVNOs. The chassis tunes both blocks together through the included Yagi donor aerial and up to three indoor whips across a 500 m² property for fifty simultaneous users.
On an EE, BT, ASDA or Virgin SIM, why does the 1800 MHz layer keep calling and browsing inside a large property where the handset alone drops?
EE allocates the 1800 MHz spectrum across both circuit voice and 4G packet data, so one handset keeps a normal call and a 4G session on the same band stages the DW500 amplifies. The ≥65 dB downlink gain recovers the faint block behind masonry, double glazing and concrete slabs, and the interior whip re-radiates it through the reception, upper bedroom, meeting room and bar area; no separate voice band is required for these EE-family brands.
For an O2, Vodafone or Three handset that cannot hold a newer data bearer, what 3G redundancy does the 2100 MHz block provide across the premises?
Band 1 3G UMTS supports both circuit voice and packet data, so an O2, Vodafone or Three handset can still call, text, send a location fix or hold a low-bandwidth hotspot session over the amplified 2100 MHz block where its newer 4G layer is weak or absent. This shared cross-network fallback is what a single-band Band 3 repeater cannot offer, and it keeps mixed-carrier staff, customers and family members connected through the main rooms and branch whips.
How does the flagship 20 dBm output and 60/65 dB gain differ from the 250m² and 200m² tiers, and what enables the three-whip 500m² field?
The DW500 keeps the same ≥60 dB uplink and ≥65 dB downlink gain as the middle tiers but raises the output to ≥20 dBm: roughly double the DW250's ≥17 dBm and about ten times the DW200's ≥10 dBm over the 10 dB gap. That extra headroom feeds three splitter branches and fifty users across a wide footprint, while the ≤5 dB noise figure keeps the field clear of hiss and the included Yagi supplies a stronger combined donor bearing than the lower-tier donor aerials.
List the MVNO brands by their leased host on this flagship kit, and explain which SIMs miss the EE 1800 call circuit.
EE, BT Mobile, ASDA Mobile, Virgin Mobile, Orange, T-Mobile and The People's Operator ride the EE host and receive the Band 3 voice and 4G layer; giffgaff, Tesco Mobile, Sky Mobile, Lycamobile and Plusnet ride O2; Smarty and iD Mobile ride Three; Lebara and Talkmobile ride Vodafone; FreedomPop and TalkTalk lease a fallback host per plan. Only the EE-hosted brands receive the Band 3 call circuit; every other host relies on Band 1 3G indoors through this chassis.
Outside the local 3G coverage footprint, which handset family keeps circuit voice through Band 3, and which non-EE family has no repeatable fallback?
EE, BT, ASDA and Virgin handsets keep circuit voice on the tuned Band 3 layer even where the surrounding area has no 3G coverage, because that voice circuit is part of the 1800 MHz block the DW500 amplifies. A member of the household or staff on O2, Vodafone or Three loses its repeatable circuit fallback through this chassis, since Band 1 is the only voice layer those hosts receive here; that handset depends on the host's own network fallback, which the repeater cannot manufacture.
When a phone switches off 4G Calling in its connection settings, which Band 3 channel restores the EE-family conversation on this DW500 install?
With Voice over LTE switched off, the EE-family handset falls back to the Band 3 circuit voice channel, the same 1800 MHz block the chassis amplifies beside the 4G data layer; the call follows the main whip and any branch whips like a normal Band 3 session. This fallback applies only to EE-hosted brands, because non-EE hosts receive no Band 3 circuit channel on this model.
List the 800 MHz rural data, 900 MHz legacy voice and 5G conditions this radio cannot serve, and name the alternative Boost4U family each matching buyer should compare.
The DW500 carries no Band 20 800 MHz rural 4G, no Band 8 900 MHz legacy voice and no 5G NR layer; a property whose only outside reading sits on 800 MHz should compare the CD500, CG500 or CW500 combos, a handset that depends on a 2G circuit call needs a Band 8 model such as the CG500, and a 5G requirement cannot be met by any current indoor repeater in this range. The chassis also cannot help where the outside phone reads zero bars on the tuned bands.
What minimum external bar count does the donor need before the flagship repeater amplifies anything, and which structural pockets cannot be reached indoors?
The Yagi donor needs at least one to two bars outside the property on the target Band 3 or Band 1; the chassis amplifies an existing weak block and cannot create signal where the mast transmits nothing. A basement below the donor floor, a steel barn or insulated metal workshop, a concrete strongroom, and a separate outbuilding behind a thick party wall generally cannot be reached from the main chassis and need their own donor and repeater rather than a pushed-through whip.
What Ofcom licence status applies to this indoor unit, which conformity marks back it for the UK and EU market, and what separation keeps the amplified field from feeding the macro masts?
The DW500 sits in the Ofcom licence-exempt mobile repeater class for indoor use and carries UKCA, CE and RoHS conformity marks. Feedback onto the macro masts is prevented by the 10 m vertical separation between the Yagi donor and the indoor whips, correct BS and MS port connection, separate indoor and outdoor lead routing, and automatic gain control that balances the field as handsets move between rooms; an over-close whip or reversed port can latch oscillation that these spacing rules are designed to stop.
